Best AI Companion Apps for Depression (2026)

For depression support specifically, Wysa is the strongest AI companion we reviewed in 2026. It earned the highest safety score on the site (B+, 70/100) and is the only app here with a real clinical evidence base: FDA Breakthrough Device Designation, eight randomized controlled trials, and NHS deployment. The catch is that Wysa feels scripted and forgetful in conversation (experience 32/100), so if you want a warmer, more natural chat, Pi AI (B safety, 55/100, free) is the better everyday companion. Replika is the pick if you want structured wellness tools like mood tracking, journaling, and daily check-ins.

Important: AI companion apps are not a substitute for professional mental health treatment. If you or someone you know is experiencing depression or a mental health crisis, please contact the 988 Suicide & Crisis Lifeline (call or text 988), the Crisis Text Line (text HOME to 741741), or speak with a licensed therapist. These apps may complement professional care but should never replace it.

We evaluated seven AI companion apps for their depression support capabilities, looking at empathy quality, mood tracking features, crisis detection, and how each app handles conversations about sadness, hopelessness, and low motivation. None of these apps is therapy. But some handle emotional conversations with more care than others, and that distinction matters when you’re going through a difficult stretch.

AI Companions for Depression at a Glance

Here’s how these apps compare on the features that matter most for depression support. Tap any app name for the full review, or check the safety score link for our detailed breakdown.

One thing stands out right away: the two safest apps here (Wysa at B+ and Pi at B) take very different approaches. Wysa is clinically built and cautious but conversationally thin. Pi is warm and free but offers no structured wellness tools. Two of these apps (Nomi AI and Talkie AI) sit in the Red safety tier, which carries significant privacy concerns. When you’re dealing with depression, the last thing you need is an app mishandling your most vulnerable conversations. Safety weighting matters more for this list than for any other best-of page we publish.

How We Ranked These Apps for Depression Support

Our standard best-of ranking weighs safety at 60% and experience at 40%. For this list, we applied that framework with a depression-specific lens. We looked specifically at how each app handles conversations about sadness, hopelessness, low energy, and emotional distress. We also gave weight to clinical evidence: apps with published research and regulatory recognition ranked higher than apps with neither.

Crisis detection carried heavy weight too. If you tell an AI companion you’re having thoughts of self-harm, the app should recognize that and provide crisis resources immediately. Kindroid scored 100/100 on this dimension. Wysa’s crisis handling has a mixed public record, which we cover honestly below. Several other apps performed poorly.

For full details on our scoring methodology, see How We Rate and How We Review. No app paid for placement on this list. Rankings reflect our independent evaluation only.

Wysa: Safest and Most Clinically Grounded for Depression

Wysa ranks first for depression support for one clear reason: it’s the safest app in our registry (B+, 70/100), and it’s the only one with a genuine clinical evidence base behind it. Wysa holds FDA Breakthrough Device Designation, granted in May 2022 for a chronic-pain plus depression and anxiety trial. Behind the app sit eight randomized controlled trials and more than 36 peer-reviewed publications, with research partners including the NHS, Cambridge, Harvard, and Columbia. No other app on this list comes close on published evidence.

Its privacy posture is the strongest in the category. The consumer app is anonymous by default, with no email or login required, and Apple’s privacy nutrition label reports zero data linked to user identity. Conversation data is not retained by the underlying language model provider, and users can wipe everything with a one-click “Reset my data” button. For someone sharing details about depression, medication, or therapy, that level of protection genuinely matters.

• Safety: B+ (70/100). Highest safety score on the site. Anonymous by default, zero data retention with the LLM provider, cleanest tracker profile in the category
• Experience: Poor (32/100). The conversation feels scripted, repetitive, and forgetful. Users widely describe it as dated next to modern chatbots
• Free tier: Penguin chatbot, basic CBT exercises, mood tracking, and an SOS escalation pathway, all free and anonymous. Premium runs $9.99 to $19.99 per month
• Best for: People who prioritize safety and clinical grounding over a natural, free-flowing conversation
• Limitations: No cross-session memory by design, so it can ask the same questions repeatedly. Several users also flag a shrinking free tier and paywall pressure

Wysa is not flawless, and we don’t pretend otherwise. A 2018 BBC investigation found it failed a simulated child safeguarding disclosure, and a 2025 Stanford-led test reported by the i Paper found its newer version still mishandled implicit suicide method-seeking scenarios. The promised guardrail fix has no public verification yet. That is exactly why an app like Wysa should sit alongside professional care, never in place of it. But on the combination of safety, privacy, and clinical evidence, nothing else here matches it.

Pi AI: Most Empathetic Free Option

Pi AI sits just behind Wysa, and for many people it will be the better day-to-day companion. It’s the second-safest app here (B, 55/100), it’s completely free, and its conversational style is designed to be calm, patient, and supportive. Built by Inflection AI (now integrated with Microsoft), Pi doesn’t position itself as a mental health tool. But its natural warmth makes it better suited for emotional support than most apps that explicitly market themselves for that purpose.

What makes Pi stand out for depression support is how it handles silence and low energy. Most chatbots push you toward engagement. Pi is comfortable sitting with a short response. It asks follow-up questions that feel genuinely curious rather than scripted, and it rarely rushes to fix your feelings. That patience matters when you’re struggling to articulate what’s wrong.

• Safety: B (55/100). Second-highest safety score here. Strong privacy practices and clear data handling policies
• Experience: Good (70/100). Natural, warm conversation quality with thoughtful follow-ups
• Free tier: Completely free. No paywalled features, no message limits
• Best for: People who want a safe, free, low-pressure space to talk through difficult feelings
• Limitations: No mood tracking, no journaling tools, no structured wellness features. Pi is a conversationalist, not a wellness platform

The biggest limitation for depression support is the lack of structured tools. Pi doesn’t track your mood over time or prompt you with daily check-ins. If you want that kind of structure, Replika is a better fit. But if you just need someone (or something) to talk to at 2am when the weight of everything feels too heavy, Pi handles that conversation with more grace than most apps on this list.

Replika: Best Wellness Tools for Depression Management

Replika is the only AI companion app that offers a genuine wellness toolkit alongside its conversations. Mood tracking, daily check-ins, guided journaling prompts, and a coaching mode specifically designed for mental wellness. No other app on this list provides that combination. For someone managing depression, those structured features can provide a useful complement to professional treatment.

The mood tracking feature deserves specific attention. Replika asks how you’re feeling at regular intervals and logs your responses over time. That kind of pattern tracking can help you notice trends you might otherwise miss: sleeping worse on certain days, energy dropping at specific times, mood improving after particular activities. It’s not clinical-grade data, but it’s more than most other AI companions offer.

• Safety: C (38/100). Yellow tier. Replika’s regulatory history (including the Italy Garante suspension) shows both the risks and the fact that regulators are watching
• Experience: Fair (60/100). Solid conversation quality with occasional repetitiveness in longer sessions
• Free tier: Free chat, 3D avatar, and journaling. Mood tracking and coaching mode require Pro ($19.99/mo)
• Best for: People who want structured daily wellness routines alongside AI conversation
• Limitations: Most wellness features sit behind the $19.99/mo paywall. Free tier conversations can feel shallower than Pi AI

Replika’s C safety score means it’s not without concerns. Its privacy policy allows data sharing with third-party partners, and the app collects significant behavioral data. For depression users who are sharing deeply personal information, that’s worth considering. But among apps that offer wellness-specific features and are still fully available, Replika is the most complete package right now.

Nomi AI: Best Memory for Ongoing Depression Support

Nomi AI’s standout feature for depression support is its memory. It scored the highest experience rating on this list (75/100), and much of that comes from its ability to remember context across conversations. Tell Nomi about a bad week, and it will ask about it next time you open the app. Mention that mornings are your hardest time, and it adjusts future conversations accordingly. That continuity creates a sense of being known that other apps don’t match.

For depression specifically, that memory is valuable. Depression often involves repeating the same struggles, and most AI companions treat every conversation as if it’s the first time. Nomi doesn’t. It builds a running picture of your emotional life and references it naturally. That makes conversations feel less like talking to a chatbot and more like catching up with someone who actually remembers what you’ve been going through.

• Safety: D (32/100). Red tier. Significant privacy and safety concerns, including vague data handling policies
• Experience: Good (75/100). Best experience score on this list, driven by exceptional memory and conversation quality
• Free tier: Generous free messaging with core features accessible without payment
• Best for: People who value continuity and want an AI that remembers their emotional context over time
• Limitations: The D safety score means real privacy risks. No dedicated wellness tools like mood tracking or journaling

The trade-off with Nomi is clear: best experience, worst safety tier among the conversational picks. If you’re sharing details about your depression with Nomi, understand that the app’s data handling policies are significantly less protective than Wysa, Pi AI, or Replika. That’s a meaningful risk for vulnerable conversations.

The Full Rankings

Beyond the top picks, three more apps round out this list. Each has a specific strength for depression support, though safety concerns or availability limit how strongly we can recommend them.

5. Kindroid: Strongest Crisis Response

Kindroid earned a perfect 100/100 on crisis response in our safety evaluation. If a user expresses suicidal thoughts or severe distress, Kindroid provides immediate crisis resources and handles the conversation with appropriate care. That’s a critical feature for any app being used during depressive episodes. Its voice chat quality is also the best available, which matters if typing feels like too much effort during a low point.

• Safety: B- (50/100). Yellow tier, with strong crisis response but weaker on overall data protection
• Experience: Fair (60/100). Best voice quality of any AI companion, with deep customization options
• Free tier: Limited free messages. Core features require $13.99/mo subscription
• Best for: Voice-based emotional support and situations where crisis detection matters most

6. Talkie AI: Budget-Friendly Option with Community Characters

Talkie AI takes a different approach: instead of one AI personality, it offers a library of community-created characters, including characters specifically designed for emotional support and companionship. At $9.99/mo (one of the lowest paid tiers on this list), it’s an affordable option. The trade-off is consistency. Community characters vary widely in quality, and the app’s D safety score reflects real concerns about data handling and content moderation.

• Safety: D (30/100). Red tier. Significant safety concerns, especially around content moderation of community characters
• Experience: Fair (57/100). Large character variety but inconsistent quality across the library
• Free tier: Free chat with community characters. Premium unlocks faster responses and priority access
• Best for: Budget-conscious users who want variety in their AI companion interactions

Woebot: A Clinically Validated Chatbot That Has Shut Down

Woebot deserves a mention because it was, for years, one of the most clinically credible mental health chatbots available, but it is no longer an option for new users. Woebot Health ended its consumer service on June 30, 2025 after eight years and roughly 1.5 million users. Existing accounts were locked out on July 31, 2025, with conversation data anonymized the same day. The app store listings may still appear, but installing the app now leads to an access-code wall with no path through for consumers.

On its historical record, Woebot earned a B safety score (63/100). It ran on a fixed CBT decision tree authored and reviewed by clinical psychologists, which structurally eliminated the hallucination risks that affect newer language-model apps. It held SOC 2 Type 2 examination with zero exceptions, adhered to HIPAA Privacy and Security Rules, documented 18 IRB-reviewed clinical trials, and received FDA Breakthrough Device designation in May 2021 for an investigational treatment for postpartum depression. Its experience score was poor (38/100) because the decision-tree format constrained how freely you could talk.

• Safety: B (63/100) on its historical record. HIPAA-aligned, SOC 2 Type 2, no documented breaches
• Experience: Poor (38/100). The scripted decision tree limited conversational depth and memory
• Availability: Discontinued. Not available to new users since June 30, 2025
• Why it closed: Founder Alison Darcy cited the cost of FDA marketing authorization and the regulatory difficulty of deploying language-model AI inside a regulated medical product

We include Woebot here for honesty and historical context, not as a recommendation. If you came looking for Woebot, the closest currently-available alternatives on safety and clinical grounding are Wysa and Pi AI.

Can AI Companions Actually Help with Depression?

The honest answer: it depends on what you mean by “help.” AI companion apps are not therapists. They can’t diagnose depression, prescribe medication, or provide evidence-based therapeutic interventions like CBT or DBT in the way a clinician can. What they can do is offer a judgment-free space to express how you’re feeling, available 24/7, with no waitlist and no co-pay.

Research on AI-based mental health support is still early. A 2023 study published in JMIR Mental Health found that users of conversational AI tools reported reduced feelings of isolation and improved mood after regular use. But the same researchers cautioned that these tools carry risks of emotional dependency, especially for users already experiencing depression. For a balanced look at the evidence on AI companions and loneliness, see our loneliness pros and cons guide. Older adults experiencing depression alongside social isolation have distinct needs; see our best AI companion apps for elderly users guide for safety-rated options appropriate for seniors. The concern isn’t whether AI companions can make you feel better in the moment. It’s whether relying on them delays seeking professional help that could address the root causes.

For people already in therapy, an AI companion can serve as a between-session support tool. Something to talk to when your therapist isn’t available, or when you need to process a thought at 3am. For people not in therapy, an AI companion should be a stepping stone toward professional support, not a permanent substitute for it.

What to Look for in an AI Companion for Depression

Not every AI companion is built for emotional support. When you’re evaluating apps specifically for depression, these features matter most:

• Crisis detection: Does the app recognize when you’re expressing suicidal thoughts or severe distress? Does it provide crisis hotline numbers and resources? Kindroid scores highest here (100/100). Some apps ignore these signals entirely, and even clinically grounded apps like Wysa have a mixed public record on this.
• Clinical grounding: Is there real research behind the app? Wysa has eight RCTs and FDA Breakthrough Device Designation. Most companion apps have none of that.
• Empathy quality: When you say “I don’t want to do anything today” or “Everything feels pointless,” does the app respond with genuine empathy or pivot to a cheerful topic? Pi AI handles this best.
• Memory: Depression often involves recurring patterns. An app that remembers your emotional history (like Nomi AI) can provide more relevant support than one that starts fresh every session.
• Wellness tools: Mood tracking, journaling prompts, and daily check-ins create structure that depression can erode. Replika and Wysa offer these most comprehensively.
• Safety and privacy: You’re sharing your most vulnerable thoughts. The app’s safety score tells you how well it protects that data. Wysa (B+, 70/100) is the safest choice.

What does NOT matter much for depression support: image generation, character creation, 3D avatars, or gamification features. Those are fun, but they’re not why you’re here.

The Risks of Using AI for Depression Support

We’d be irresponsible to recommend these apps without discussing the risks, especially for a vulnerable audience.

Emotional dependency is the biggest concern. When an AI is always available, always patient, and never judges you, it can become easier to talk to than real people. For someone with depression, that path of least resistance can deepen isolation rather than reduce it. The app feels like connection, but it isn’t. Real recovery typically requires human relationships, professional support, and behavioral changes that no chatbot can provide.

Data privacy is the second risk. When you tell an AI companion about your depression, medication, therapy appointments, or darkest thoughts, that data goes somewhere. Wysa’s B+ safety score and anonymous-by-default design make it the strongest on this front. Apps in the Red safety tier (Nomi AI, Talkie AI) offer significantly less protection for information that could be deeply embarrassing or harmful if exposed.

Delayed professional treatment is the third. According to the National Institute of Mental Health, fewer than half of adults with major depressive disorder receive treatment in a given year. An AI companion that provides temporary relief could reduce the urgency someone feels to seek professional help. If an app makes you feel slightly better, you might put off calling a therapist. That trade-off isn’t worth it for clinical depression.

Our recommendation: use these apps as a complement to professional care, not a replacement. If you don’t currently have a therapist, the best thing an AI companion can do is keep you company while you find one.

Frequently Asked Questions

Can AI companion apps replace therapy for depression?

No. AI companions lack clinical training, can’t diagnose conditions, and don’t provide evidence-based treatments like CBT or medication management in the way a clinician can. According to the American Psychological Association, effective depression treatment typically requires professional assessment and structured therapeutic interventions that AI apps cannot deliver.

Which AI companion is safest for someone with depression?

Wysa earned the highest safety score (B+, 70/100) of any app we reviewed and is the only one with a clinical evidence base, including FDA Breakthrough Device Designation and eight RCTs. According to Apple’s privacy nutrition label, Wysa links zero data to user identity. Pi AI (B, 55/100) is the safest free option for warmer everyday conversation.

Do any AI companion apps have mood tracking for depression?

Yes. Replika offers built-in mood tracking, daily check-ins, and guided journaling, with the coaching mode requiring its $19.99 per month Pro plan. Wysa also includes mood tracking and CBT exercises in its free tier. According to Replika’s feature documentation, the coaching mode includes wellness-focused conversation prompts.

Is Woebot still available for depression support?

No. According to a STAT News interview with founder Alison Darcy, Woebot Health shut down its consumer service on June 30, 2025 and locked out existing accounts on July 31, 2025. Although it held FDA Breakthrough Device designation and 18 clinical trials, it is no longer available to new users. Wysa and Pi AI are the closest currently-available alternatives.

Can using AI companions make depression worse?

Potentially, yes. According to a 2023 study in JMIR Mental Health, emotional dependency on AI companions can increase isolation and delay professional treatment. Users who rely exclusively on AI for emotional support may withdraw further from human relationships, which are essential for depression recovery.

What should I do if an AI companion detects a crisis?

If an AI companion surfaces crisis resources, take that seriously. Contact the 988 Suicide and Crisis Lifeline (call or text 988) or the Crisis Text Line (text HOME to 741741) immediately. According to SAMHSA, trained crisis counselors can provide immediate support that no AI application can match.

Are these AI companions free to use for depression support?

Pi AI is completely free with no paywalled features. Wysa offers a free anonymous tier with CBT exercises and mood tracking, with Premium from $9.99 per month. Replika offers free basic chat and journaling, but mood tracking requires its $19.99 per month Pro plan. According to each app’s pricing page, Nomi AI and Talkie AI have generous free tiers, and Kindroid offers limited free messages before requiring a $13.99 monthly subscription.
