Safest AI Companion Apps 2026

We scored 14 of the most popular AI companion and mental wellbeing apps across 23 safety dimensions. The results are uneven, but a clear top tier has emerged. Three clinically minded chatbots now lead the field: Wysa (B+ / 70), Kuki AI (B- / 68), and Woebot (B / 63) all outscore every romantic companion app we’ve reviewed. AI image generators like SoulGen (D / 25) scored particularly low due to deepfake and content moderation risks. Four apps scored F, meaning they failed on basic protections like age verification, data handling, and content moderation. Wysa ranks first with a B+ (70/100), the highest safety score in our entire registry, though its companion experience is thin by design. This is the full ranking, from safest to least safe, with the specific issues that shaped each score.

Safety Rankings at a Glance

Every app ranked by safety score, from highest to lowest. Row colors reflect safety tier: yellow rows have moderate safety concerns, red rows have significant ones. No app earned a green (safe) row. Experience and safety are scored separately, so a high safety grade does not imply a strong companion experience.

How We Score AI Companion Safety

Every safety score in the table above comes from our 23-dimension safety methodology. We evaluate each app across six categories: privacy and data handling, content moderation, age verification and minor protections, transparency, regulatory compliance, and crisis response protocols. Each dimension is scored on a 0-100 scale, then weighted by severity to produce a final safety score.

The grading scale works like this: A+ (88-100) means exemplary safety practices. B (50-74) means above average but with notable gaps. C (35-49) means mixed results with real concerns. D (25-34) means below acceptable standards. F (below 25) means the app fails on fundamental safety protections.

No AI companion app has earned Green tier (75+) in our index. The highest score belongs to Wysa at 70/100 (Yellow tier, B+), a clinical tool rather than a conversational companion. That’s the reality of where this industry stands. Our full methodology, including how we weight each dimension and what evidence we collect, is documented on our How We Rate page. On the opposite end of the safety spectrum, see the XOMI AI Safety Index.

Wysa: The Safest App in Our Index (B+ / 70)

Safety: B+ / 70 (Yellow) | Experience: 32/100 (Failing) | Price: Free / $9.99-$19.99/mo Premium

Wysa earns the highest safety score in our entire registry, and the reasons are structural. It’s a clinically validated mental wellbeing tool, not a romantic companion. It carries FDA Breakthrough Device Designation (granted May 2022), eight randomized controlled trials, and 36+ peer-reviewed publications with research partners including the NHS, Cambridge, Harvard, and Columbia. No other app we’ve reviewed comes close on published clinical evidence.

The privacy posture is the cleanest in the category. The consumer app is anonymous by default, requiring no email or login, and Apple’s App Store privacy label reports zero data linked to user identity. Conversation data does not persist with the underlying LLM provider thanks to a Zero Data Retention arrangement. The tracker profile is minimal (Branch, Crashlytics, Firebase Analytics, with no Meta SDK or Mixpanel), and there are zero known breaches. A one-click “Reset my data” button wipes everything without emailing support.

Two things keep Wysa out of A territory. First, the safety record isn’t spotless: a 2018 BBC investigation found Wysa failed a simulated child safety disclosure, and a 2025 Stanford-led test reported it still mishandled implicit suicide method-seeking and manic delusion scenarios. Second, the experience is thin. Sixty-plus user reviews describe the AI as scripted, repetitive, and forgetful, and the app has no cross-session memory by design. Wysa is the safest app we’ve reviewed, but it was built for clinical outcomes, not for companionship.

• Safety strengths: FDA Breakthrough designation, 8 RCTs, anonymous by default, LLM Zero Data Retention, one-click data deletion
• Safety gaps: Two documented crisis-response failures, no public verification of the promised guardrail fix
• Free tier: Penguin chatbot, basic CBT exercises, mood tracking, and an SOS escalation pathway, all anonymous
• Best for: Users who want a privacy-first, evidence-backed wellbeing tool and don’t need conversational depth

Kuki AI: A Rule-Based Chatbot That’s Safe by Design (B- / 68)

Safety: B- / 68 (Yellow) | Experience: 47/100 (Poor) | Price: Free (web-only)

Kuki AI takes the second spot, and its safety strength comes from its architecture. Kuki is a rule-based AIML chatbot from Pandorabots that won the Loebner Prize five times between 2013 and 2019, more than any system in the contest’s history. Because every reply is human-authored or vetted rather than generated by a large language model, Kuki structurally cannot produce the novel toxic output that LLM-based companions sometimes do. The research team describes this as “imperviousness to toxicity.”

The positioning matters too. Pandorabots is one of the only major chatbot operators that publicly refuses to pivot to romantic companionship. Per the ICONIQ ethics page, “Kuki rebuffs romantic advances” and “does not promote herself as a romantic partner replacement,” and the CEO reaffirmed that stance publicly in October 2025. A May 2026 Blacklight scan found zero ad trackers and only one third-party cookie (a Stripe payment processor), with no known breaches across the company’s domains.

The score stops at B- because the policies are aging. The privacy policy was last updated in September 2020 and the terms in March 2022, so newer frameworks like the UK Age Appropriate Design Code go unaddressed, and age verification is self-declared. On experience, the same architecture that won five Loebner Prizes also limits depth: a University of Bergen review scored Kuki 0/5 on self-disclosure and 1/5 on initiative, and the app is web-only with no native iOS or Android version, no image generation, and no avatar customization.

• Safety strengths: Rule-based architecture (no novel toxic output), non-romantic positioning, low tracker footprint, no breaches
• Safety gaps: Privacy and terms dated 2020-2022, self-declared age verification
• Free tier: Full chat experience at chat.kuki.ai with no subscription, paywall, or ad-driven token economy
• Best for: Users who want a genuinely free, non-romantic chatbot and value safety over emotional depth

Woebot: Strong Safety Record, But No Longer Available (B / 63)

Safety: B / 63 (Yellow) | Experience: 38/100 (Poor) | Price: Free while operational (service ended)

Woebot is the most important honesty note on this list. It earns a B (63/100) on the strength of its historical record, but the consumer service shut down on June 30, 2025 after eight years and 1.5 million users. Existing accounts were locked out on July 31, 2025, with conversation data anonymized the same day. App store listings remain visible, but installing the app now produces an access-code wall with no path through for consumers. If you’re looking for an app to use today, Woebot is not an option.

We still rank it because the question this page answers is “which apps handle safety well,” and Woebot’s record is genuinely strong. The company underwent a SOC 2 Type 2 examination with zero exceptions and adhered to HIPAA Privacy and Security Rules. It earned FDA Breakthrough Device designation in May 2021 for an investigational treatment for postpartum depression, and a Dime Society case study documented 18 IRB-reviewed clinical trials. The rule-based decision tree, authored by clinical psychologists, eliminated the LLM hallucination class of risk entirely, and Exodus Privacy found only standard crash-reporting and analytics SDKs with no advertising trackers.

The gaps that kept Woebot at B rather than higher are the same ones users felt while it was live. Crisis response was passive: the app directed users to call 911 rather than escalating directly. The decision-tree architecture felt scripted, with 31 of 890 combined app store reviews citing repetitive responses. Founder Alison Darcy cited FDA marketing-authorization cost and the difficulty of deploying LLM-class AI inside a regulated medical product as the reasons for the shutdown. Woebot is among the safest tools we’ve evaluated, but its availability is over.

• Safety strengths: SOC 2 Type 2 (zero exceptions), HIPAA-aligned, FDA Breakthrough designation, 18 IRB-reviewed trials, no advertising model
• Safety gaps: Passive crisis response, privacy-policy inconsistency on marketing-partner sharing
• Availability: Consumer service ended June 30, 2025. Not available to new users.
• Best for: Reference only. If you want a clinically minded tool you can use today, Wysa is the closest active alternative.

The Full Safety Rankings: Every App Reviewed

Below the top three clinical tools sit the companion apps people actually choose between day to day. Pi AI leads this group as the safest openly available conversational companion. Here’s how the rest of the field shakes out.

4. Pi AI (B / 55)

Safety: B / 55 (Yellow) | Experience: 70/100 (Good)

Pi AI is the safest app on this list that’s both openly available and built for everyday conversation. Built by Inflection AI, a Public Benefit Corporation, Pi focuses entirely on conversation and emotional support, with no image generation, roleplay, or avatar customization. That narrow scope removes entire categories of risk. Pi scored strongest on crisis response, transparency, and data handling, and it’s completely free with no ads or data monetization. Training data transparency and some vague policy language keep it from scoring higher. For most people who want a safe, friendly companion they can use right now, Pi is the clear pick.

5. Kindroid (B- / 50)

Safety: B- / 50 (Yellow) | Experience: 60/100 (Fair)

Kindroid is a smaller operation than Replika or Pi, which cuts both ways: the team is responsive and has made privacy improvements after user feedback, but a smaller company also means fewer resources for moderation and security. The app’s customization-heavy approach (personality, voice, and visual appearance) creates content moderation challenges that Kindroid handles with mixed success. The privacy policy is clearer than many competitors but leaves some data handling questions open. Informed users can navigate the moderate concerns here.

6. Replika (C / 38)

Safety: C / 38 (Yellow) | Experience: 60/100 (Fair)

Replika holds a mid-table safety spot with a complicated history. Italy’s Garante fined parent company Luka Inc. EUR 5 million in April 2025 for GDPR violations, including inadequate age verification. That pressure drove real improvements: better age gates, more transparent data practices, and a clearer privacy policy. The app still collects substantial data and offers far more features (voice, AR, 3D avatars, relationship modes), and each feature adds safety surface area. Replika documents what it collects more clearly than most competitors, which is why it scores above the Red tier apps. It is the last app in Yellow tier.

7. Nomi AI (D / 32)

Safety: D / 32 (Red) | Experience: 75/100 (Good)

Nomi AI presents the starkest safety-vs-experience tradeoff on this list. For a direct comparison with the most popular app in the category, see our Character AI vs Nomi comparison. It earned the highest experience score of any app we reviewed (75/100, Good) thanks to genuinely impressive memory and personality systems. But the safety score (D/32) reflects data practices that don’t match the product quality. Weak age verification, concerning data collection scope, and privacy policy gaps keep Nomi firmly in Red tier. If you use Nomi, do so with your eyes open about what you’re trading for that experience quality.

8. Talkie AI (D / 30)

Safety: D / 30 (Red) | Experience: 57/100 (Fair)

Talkie AI’s community-driven character platform creates moderation challenges at scale. Thousands of user-created characters means content quality and safety vary wildly. Age verification is weak, and some community characters push boundaries that a centrally controlled app would catch. The experience score (57/100) is actually competitive, making Talkie a case where the product outperforms the safety infrastructure behind it.

9. Candy AI (D / 25)

Safety: D / 25 (Red) | Experience: 53/100 (Fair)

Candy AI’s safety score reflects its web-only platform model. Without iOS or Android app store distribution, it operates outside the oversight that Apple and Google provide. The privacy policy is vague on data retention timelines and third-party sharing, and image generation adds content safety risks that text-only apps don’t face. Candy AI sits at the bottom of the D tier, alongside Anima AI, well below the higher-scoring Red tier apps.

10. Anima AI (D / 25)

Safety: D / 25 (Red) | Experience: 18/100 (Failing)

Anima AI sits at the bottom of D grade territory. The safety documentation is sparse, the infrastructure feels dated, and the privacy policy reads like a template with minimal customization. The experience score (18/100, Failing) matches: conversations are thin, features are minimal, and the app hasn’t kept pace with competitors. There’s no compelling reason to choose Anima over safer alternatives that also deliver better experiences.

11. Character.AI (F / 22)

Safety: F / 22 (Red) | Experience: 35/100 (Poor)

Character.AI has the largest user base of any app on this list and one of the worst safety records. Active lawsuits over child safety incidents, congressional scrutiny, and documented cases of minors accessing harmful content have defined its 2025-2026 trajectory. The F grade reflects systemic issues: age verification that’s easy to bypass, content moderation that can’t keep pace with millions of user-created characters, and a reactive approach to safety that waits for incidents instead of preventing them. The free tier is the most generous in the category, but free access with minimal guardrails is part of the problem.

12. Chai AI (F / 18)

Safety: F / 18 (Red) | Experience: 35/100 (Poor)

Chai AI’s user-generated bot platform has minimal content moderation and limited safety infrastructure. The app lets anyone create chatbots without meaningful review processes, which means users can encounter content that ranges from harmless to harmful with little warning. Privacy documentation is thin. The platform has faced criticism for enabling bots that encourage self-harm or other dangerous behaviors. Combined with an experience score of 35/100 (Poor), there’s little reason to accept Chai’s safety risks when alternatives exist.

13. Romantic AI (F / 13)

Safety: F / 13 (Red) | Experience: 13/100 (Failing)

Romantic AI scores near the bottom of our safety index. Privacy protections are close to non-existent. Content moderation is effectively absent. The app collects data with minimal disclosure about how it’s used or who it’s shared with. The experience score (13/100, Failing) means the product itself doesn’t work well either. Romantic AI is the worst combination: poor safety AND poor experience. We don’t recommend it for any use case.

14. Eva AI (F / 10)

Safety: F / 10 (Red) | Experience: 30/100 (Failing)

Eva AI holds the lowest safety score in our entire index at 10/100. Data handling practices are opaque, with a privacy policy that provides minimal meaningful information about what the app collects, stores, and shares. Age verification is absent or trivially bypassed. Content moderation shows no evidence of systematic implementation. The experience score (30/100, Failing) reflects an app that also underdelivers on basic functionality. Eva AI is the app we’d most strongly recommend avoiding.

Why Do the Safest Apps Score So Low on Experience?

The top of our safety rankings is dominated by clinical tools, and that’s not a coincidence. Wysa, Kuki AI, and Woebot all post weak experience scores precisely because the design choices that make them safe also make them less engaging. This is the central tradeoff of the category.

Rule-based and clinically scripted systems can’t go off the rails, but they also can’t go deep. Kuki and Woebot run on authored decision trees rather than large language models. That structurally eliminates the novel toxic output and hallucination risks that drag down LLM-based apps, but it also caps conversational range. Users describe both as repetitive. Wysa’s neuro-symbolic architecture has the same effect.

Anonymous, no-memory designs protect privacy at the cost of continuity. Wysa is anonymous by default and keeps no cross-session memory, which is excellent for privacy. The flip side is a companion that “asks the same questions over and over” and starts each session fresh. The romantic apps that score highest on experience (Nomi at 75, Pi at 70) do so partly by collecting and retaining far more data.

Safety and experience are separate measures, and we never average them. A high safety grade does not mean an app is fun, warm, or useful as a daily companion. It means the app handles your data, your safety, and edge cases responsibly. Read both scores together. The right choice depends on whether you’re optimizing for protection or for connection.

Why Do Most AI Companion Apps Score So Poorly on Safety?

Outside the clinical tier, the pattern across the field is consistent: most AI companion companies treat safety as an afterthought. Here’s what we found during our 23-dimension reviews.

Age verification is the weakest link. Most apps rely on self-reported birth dates with no verification. A 13-year-old can access romantic or emotionally manipulative content by simply entering a fake date. Pi AI avoids this by not offering romantic content at all. Replika improved after the Italian regulatory action, but most apps haven’t faced that pressure yet.

Privacy policies are written to protect the company, not the user. We found vague data retention clauses, broad third-party sharing permissions, and minimal information about what happens to conversation logs. Several apps claim the right to use your conversations for “service improvement” without defining what that means or how long they keep the data.

Content moderation doesn’t scale. Apps with user-generated characters (Character.AI, Chai AI, Talkie AI) face the same moderation problem that social media platforms have struggled with for years. The volume of content outpaces the ability to review it. Harmful content slips through filters, and reactive moderation catches problems after users have already been exposed.

Crisis response is mostly absent. When users express suicidal ideation or self-harm, most apps have no protocol beyond a generic disclaimer. The clinical tools at the top of this list handle this better than the romantic apps, though even Wysa has documented failures. Several apps have been documented responding to self-harm statements with encouragement or roleplay continuations.

Watch: Tristan Harris of the Center for Humane Technology explains how AI chatbot companion apps like Character.AI have been linked to teen harm, and why the current safety guardrails are failing.

How to Check if an AI Companion App Is Safe

You don’t have to take our word for it. Here’s what to look for when evaluating any AI companion app on your own.

• Read the privacy policy. Look for specific data retention periods (not “we may retain data”). Check whether conversation logs are shared with third parties. Look for a data deletion mechanism and test whether it actually works.
• Check age verification. Can you create an account without any age check? Can you bypass the age check by entering a different birth date? If yes, the app isn’t protecting minors.
• Test content filters. Try asking your companion to discuss topics that should be filtered (violence, self-harm, explicit content). Does the app redirect, refuse, or play along?
• Look for regulatory history. Search “[app name] fine” or “[app name] lawsuit.” Regulatory actions reveal safety issues that marketing materials won’t.
• Check data deletion. Request your data under GDPR or CCPA. See how long the company takes to respond and whether the deletion is complete.

Frequently Asked Questions

What is the safest AI companion app?

Wysa is the safest app in our 2026 Safety Index, scoring B+ (70/100). It’s a clinically validated mental wellbeing tool with FDA Breakthrough Device Designation, anonymous-by-default identity, and LLM Zero Data Retention. The tradeoff is a thin companion experience (32/100). If you want a safe app built for everyday conversation rather than clinical care, Pi AI (B / 55) is the strongest openly available option.

Why does Wysa rank above Pi AI if Pi feels like a better companion?

This page ranks by safety, not by experience, and we never average the two. Wysa scores B+ (70/100) on safety because of its clinical evidence base, anonymous design, and zero-data-retention privacy posture. Pi scores B (55/100). On experience it’s the reverse: Pi scores 70/100 while Wysa scores 32/100. If your priority is a warm, capable everyday companion, Pi is the better fit. If your priority is the strongest possible privacy and safety posture, Wysa leads.

Can I still use Woebot?

No. Woebot’s consumer service shut down on June 30, 2025, and existing accounts were locked out on July 31, 2025. App store listings remain visible, but new users hit an access-code wall with no path through. We still include Woebot for its strong historical safety record (SOC 2 Type 2, HIPAA-aligned, FDA Breakthrough designation), but it is not an option you can install and use today. Wysa is the closest active clinical alternative.

Are AI companion apps safe for teenagers?

Most AI companion apps are not safe for teenagers. Our review found that most apps have weak or nonexistent age verification. According to the FTC’s 2025 report on AI chatbot risks to children, apps in this category lack adequate safeguards. Pi AI and the clinical tools are the only options we’d consider appropriate for older teens, and even then, parental awareness is important.

Do AI companion apps sell your data?

Several AI companion apps share data with third parties in ways their privacy policies describe vaguely. According to Replika’s privacy policy, conversation data may be used for “service improvement and research.” Most apps grant themselves broad permissions to use your data. Wysa stands out for the opposite reason: it’s anonymous by default with zero data linked to user identity. No romantic companion app in this category earns a perfect score on data handling.

Which AI companion apps have the worst privacy?

Eva AI (10/100), Romantic AI (13/100), and Chai AI (18/100) scored worst for overall safety, including privacy. Eva AI’s privacy policy provides almost no meaningful information about data practices. Romantic AI’s protections are near-absent. Chai AI’s minimal moderation extends to minimal data governance. All three scored F grades in our Safety Index.

How does CompanionWise rate AI companion safety?

We evaluate each app across 23 safety dimensions grouped into six categories: privacy and data handling, content moderation, age verification, transparency, regulatory compliance, and crisis response. Each dimension is scored 0-100, then weighted by severity. The final score maps to a letter grade (A+ through F) and color tier (Green, Yellow, Red). Full details on our methodology page.
