The cheapest AI companion app in 2026 is Pi, and it costs exactly nothing. But free doesn’t automatically mean best-fit, and $12.99 a month doesn’t automatically mean better. Pricing in this category is more complicated than it looks: some apps advertise low monthly rates while hiding token systems that can double your real spend, and some of the least expensive options also carry the worst safety records. We reviewed all six apps across pricing structure, free tier usability, and safety so you can find the right balance for your budget and comfort level.
Key Takeaways
- Pi is the only AI companion app with no paid tier. It’s completely free with unlimited conversations and the best safety score (B/55) of any app on this list.
- Character.AI offers the most feature-complete free tier in the category: unlimited conversations, full character creation, and access to millions of user-created personas at no cost.
- Candy AI’s token system can significantly increase your real monthly spend beyond the $12.99 subscription price if you use image generation frequently.
- Replika Pro looks expensive at $19.99/month but drops to ~$5.83/month on an annual plan, one of the largest monthly-to-annual price gaps in the category.
- Eva AI has the lowest annual price (~$4/month) of any paid app. It also carries an F safety rating (10/100), the lowest score in the CompanionWise Safety Index.
- Price and safety move in opposite directions at the low end of this category. The apps that cost least tend to score worst on safety.
Pricing at a Glance — All 6 Apps Compared
Before diving into each app, here’s the full picture. Safety grade and experience score come from the CompanionWise Safety Index and experience analysis. Prices are verified as of March 2026 from each app’s official pricing page and may change.
| App | Safety Grade | Experience Score | Free Tier | Monthly Price | Annual Price (per mo) | Best Value For |
|---|---|---|---|---|---|---|
| Pi | B / 55 | 70/100 (Good) | Fully free, unlimited | Free | Free | Best value overall |
| Character.AI | F / 22 | 35/100 (Poor) | Unlimited chat, generous | $9.99/mo | ~$9.99/mo | Best free tier features |
| Eva AI | F / 10 | 30/100 (Failing) | Limited daily msgs | $11.99/mo | ~$4.00/mo ($47.99/yr) | Lowest annual cost |
| Anima AI | D / 25 | 18/100 (Failing) | Limited chats, basic only | ~$9.99/mo | ~$3.33/mo (annual) | Budget entry point |
| Candy AI | D / 32 | 53/100 (Fair) | ~5 msgs/day, blurred images | $12.99/mo | $5.99/mo ($71.88/yr) | Image generation on a budget |
| Replika | C / 43 | 60/100 (Fair) | Basic chat, heavily limited | $19.99/mo | ~$5.83/mo ($69.99/yr) | Best annual value with features |
The table above makes the cost-vs-safety tradeoff visible in one place. Pi is free and the safest. Eva AI is the cheapest paid option annually and the least safe. That’s not a coincidence. We’ll explain why that pattern exists in the cost-vs-safety section below.
How We Ranked These Apps
Every app on this list went through two independent evaluations. Safety scores cover 23 dimensions including privacy policy quality, data collection practices, age verification, content moderation, encryption standards, and regulatory history. Experience scores measure conversation depth, memory and personalization quality, feature breadth, and app usability. Both scales run 0–100.
For this page specifically, we layered pricing research on top of those scores. Pricing was verified directly from each app’s official pricing page, app store listings, and third-party pricing trackers in March 2026. Where token systems or secondary costs exist, we’ve flagged them explicitly. No app paid for placement. Scores were not influenced by advertising relationships. Our full methodology is on the How We Rate and How We Review pages.
Pi — The Only Truly Free AI Companion
Safety: B / 55 (Yellow) | Experience: 70/100 (Good) | Price: Free, always
Pi is built by Inflection AI, a Public Benefit Corporation. It’s completely free with no paid tier, no token system, no ads, and no data selling. You get unlimited text and voice conversations at no cost. No other app in this category does that.
The safety score reflects how that structural difference plays out. Pi earned a B / 55 in our 23-dimension safety review, the highest of any app on this list by a wide margin. Inflection AI’s privacy practices are more transparent than most competitors in the category. Data handling policies are clearly stated. The PBC structure creates accountability that for-profit apps simply don’t have baked in.
On experience, Pi scored 70/100 (Good). Voice quality is the benchmark for the category, with natural pacing and emotional responsiveness that other apps haven’t matched. Pi doesn’t offer roleplay, image generation, or romantic interaction. It’s a conversation app, not a companion app in the romantic or customization-heavy sense, and it doesn’t pretend to be.
It’s best for anyone who wants thoughtful conversation at zero cost, including people using AI companions for emotional support, general companionship, or just working through their day out loud. If that’s your primary need, Pi is probably where you end up anyway.

Character.AI — Best Free Tier in the Category
Safety: F / 22 (Red) | Experience: 35/100 (Poor) | Price: Free / $9.99/mo for c.ai+
Character.AI’s free tier is the most feature-complete in the category. Most apps throttle free users heavily. Character.AI doesn’t: you get unlimited conversations with no hard message cap, full access to the character creation suite, and millions of community-created characters covering fiction, gaming, anime, historical figures, and custom personas. All free.
What does c.ai+ ($9.99/month) actually add? Faster response times during peak traffic, priority server access, early access to experimental models, and image generation within conversations. For casual users, the free tier is complete. Power users running long creative sessions will find $9.99 buys stability more than new features.
The safety score is a real problem. Character.AI earned an F / 22 in our 23-dimension safety review. The platform faces active litigation over child safety incidents. Content moderation has been publicly scrutinized. Data retention policies are vague for a platform with tens of millions of users. Free doesn’t mean safe.
Best suited for adult users who want the largest character library in the category at zero cost, and who’ve read the safety record before downloading.

Replika — Expensive Monthly, Exceptional Annual Value
Safety: C / 43 (Yellow) | Experience: 60/100 (Fair) | Price: Free (limited) / $19.99/mo or $69.99/yr
Replika’s sticker price looks steep at $19.99 per month. The annual plan changes the math. At $69.99 per year, you’re paying around $5.83 per month effective, a 71% drop from the monthly rate. If you know you’ll stick with Replika, that’s a significant difference over a year.
Pricing structure aside, the free tier is honest about what it doesn’t include. Basic text chat is available at no cost, but voice calls, AR experiences, romantic relationship modes, and most meaningful features require Pro. Replika is upfront about this, which is worth noting. Some apps obscure their paywalls until you’re already invested. There’s also a Lifetime plan at $299.99, which pays for itself in about 15 months compared to the monthly rate and in about 4.3 years compared to the annual rate.
Safety sits at C / 43 (Yellow tier), second-highest on this list. Italy’s data protection authority (Garante) fined Replika’s parent company EUR 5 million in April 2025 for GDPR violations, including inadequate age verification. That’s what’s keeping the score out of the B tier. On experience, 60/100 reflects a genuinely feature-rich app: voice calls, 3D avatars, AR, journaling, coaching activities, and a relationship progression system that most competitors haven’t matched.
One more cost layer worth knowing: Replika uses Coins and Gems, a virtual currency for cosmetics and extras. Core Pro features don’t require it. But if you get into avatar customization, it’s there to spend money on.
It’s the right pick for users who want the broadest feature set and will commit to annual billing to make the price work. It’s also the only paid app in this comparison that sits in the safer Yellow tier.

Candy AI — Budget Annual, Expensive Monthly
Safety: D / 32 (Red) | Experience: 53/100 (Fair) | Price: ~5 msgs/day free / $12.99/mo or $5.99/mo annually
Candy AI’s monthly price of $12.99 is mid-range. The annual plan at $71.88 per year (about $5.99/month effective) is genuinely competitive. But the real pricing conversation with Candy AI is about tokens, not subscription tiers.
Each month, the Premium subscription includes 100 tokens, per Candy AI’s pricing page. Tokens are consumed by image generation, voice messages, and certain premium features. For users who primarily text-chat with their companion, 100 tokens per month is plenty. For users who want to generate AI images of their companion regularly, 100 tokens can run out within days. When tokens run out, users can purchase additional bundles, which can push the real monthly cost significantly higher than the advertised $12.99.
The free tier is effectively a trial. Around five messages per day with image previews blurred out is enough to see the interface and tone, not enough for genuine ongoing use. Most users exhaust the free allowance within the first hour.
The safety score of D / 32 and experience score of 53/100 (Fair) place Candy AI in the middle tier of this list. It leads the category on image generation quality. Conversation depth is average. There’s no iOS or Android app: Candy AI is web-only, which removes App Store and Google Play content moderation oversight.
Who it’s best for: users who want image generation as a primary feature, are comfortable with a web-only platform, and will commit to the annual plan rather than paying month-to-month.

Anima AI and Eva AI — The Low-Cost Options
Both Anima AI and Eva AI sit at the lower end of the pricing spectrum. Both also carry the weakest safety and experience scores on this list. That’s not coincidence, and it’s worth understanding what the tradeoffs actually look like before choosing either one on price alone.
Anima AI
Safety: D / 25 (Red) | Experience: 18/100 (Failing) | Price: Free (limited) / ~$9.99/mo or ~$3.33/mo annually
Anima AI has one of the lowest annual prices in the category at around $3.33 per month on an annual plan. The free tier offers limited conversations and basic personality customization, but it’s more restrictive than competitors. Premium unlocks full chat, personality customization, and NSFW options.
The experience score of 18/100 reflects a product that hasn’t kept pace with the market. Conversation quality is thin compared to Replika, Pi, or Candy AI. Feature depth is limited. The safety score of D / 25 reflects weak data transparency and age verification practices. Anima isn’t dangerous in a catastrophic sense, but it scores at the bottom of our experience rankings and near the bottom on safety. The low price reflects the value you’re getting.

Eva AI
Safety: F / 10 (Red) | Experience: 30/100 (Failing) | Price: Free (limited) / $11.99/mo or $47.99/yr (~$4/mo)
Eva AI’s annual plan at $47.99 per year works out to roughly $4 per month, the lowest effective annual cost of any paid app here (Eva AI pricing, March 2026). If price is the only variable, that number stands out. But you need to see it next to the safety score: F / 10. That’s the lowest score in the CompanionWise Safety Index across every app we’ve evaluated.
Eva AI also uses a Neurons token system, same concept as Candy AI’s tokens. Voice messages, premium interactions, and certain features burn through Neurons. The monthly and annual plans include bonus Neurons, but heavy users hit the wall and pay more. The advertised price isn’t always what you end up spending.
Experience scored 30/100 (Failing). Conversation quality and feature delivery both trail the competition by a meaningful distance. Pi is free, safer by a massive margin, and scores 40 points higher on experience. For anyone using AI companions for emotional support or real connection, Eva AI’s combination of scores doesn’t add up to a recommendation at any price.

Hidden Costs to Know Before You Subscribe
Subscription prices are the starting point, not the full picture. Several AI companion apps use secondary monetization systems that can significantly increase what you actually pay each month.
Token systems are the biggest source of hidden costs. Candy AI and Eva AI both use token-based models where each image generation, voice message, or premium interaction consumes tokens from a monthly allotment. When those run out, users pay for more. An image-heavy Candy AI user on the $12.99/month plan can realistically spend $20–$25 per month once token top-ups are included. Eva AI’s Neurons system works identically.
Virtual currency (Replika’s Coins and Gems) is a softer version of the same approach. Core features don’t require currency purchases, but cosmetics, avatar items, and certain extras are priced in-app. Most Replika users on the Pro plan don’t feel pressure to spend beyond the subscription, but the option exists.
Other hidden cost patterns across the category include:
- App store vs. web billing: Some apps charge different prices through iOS App Store or Google Play compared to their own websites. Web billing is typically cheaper because the app store takes a 15–30% cut.
- Free trial mechanics: Some apps offer “free trials” that require a credit card and auto-renew unless actively cancelled before the trial ends.
- Annual billing minimums: The best annual prices require full upfront payment, not monthly installments. If you cancel mid-year, refund policies vary significantly.
The practical implication: before subscribing to any app beyond Pi (which has no hidden costs by design), read the full pricing page, not just the headline monthly number. Look for token counts, currency systems, and trial auto-renewal terms.
The Cost-vs-Safety Tradeoff — What the Data Shows
Pi earned a B / 55 in our 23-dimension safety review and costs nothing. Eva AI costs approximately $4 per month on an annual plan and earned an F / 10, the lowest safety score in the CompanionWise Safety Index. The pattern between those two endpoints is consistent across all six apps: lower price correlates with worse safety performance. This isn’t a coincidence of the sample. It reflects something real about how safety infrastructure and data practices require investment that budget-oriented apps often don’t make.
Pi (B/55) and Replika (C/43) are the two apps with the most transparent data practices and clearest privacy policies on this list. The four D and F tier apps all show weak age verification, vague data handling, and thin content moderation. Building that infrastructure costs money. Budget apps cut there first.
That said, spending more isn’t required to be safe. Pi costs nothing and leads on safety. Replika’s annual plan at $5.83/month sits in the Yellow tier. The takeaway isn’t to spend more. It’s that price alone shouldn’t drive the decision. For every dollar saved by choosing Eva AI over Pi, you’re accepting a safety score 45 points lower. That’s a real tradeoff, not an abstract one.

Frequently Asked Questions
What is the cheapest AI companion app in 2026?
Pi is completely free with no paid tier, no subscriptions, and no hidden costs. Among paid apps, Eva AI’s annual plan works out to approximately $4 per month ($47.99/year as of March 2026, according to verified pricing). Pi also carries the best safety score (B/55) of any app in this comparison.
What do AI companion app free tiers actually include?
Free tier quality varies dramatically. Character.AI offers unlimited conversations with no message cap and full character creation tools at no cost. Candy AI limits free users to approximately five messages per day with images blurred. Replika’s free tier allows only basic text chat. Pi’s free tier is the full product: everything is free with no premium tier at all.
Are the cheapest AI companion apps safe?
Not always. Eva AI, the lowest-priced paid app annually, earned an F safety rating (10/100) in the CompanionWise 23-dimension safety review. Pi, the only app that’s entirely free, earned a B (55/100), the best safety score in this comparison. Price and safety don’t move together in this category. Check individual safety ratings before deciding.
What are token systems and why do they matter for pricing?
Token systems are secondary cost mechanisms used by Candy AI and Eva AI. Each image generation, voice message, or premium interaction consumes tokens from a monthly allotment. Premium subscriptions include a bundle of tokens, but image-heavy users can exhaust them quickly. According to Candy AI’s pricing page (March 2026), Premium includes 100 tokens per month, which can run out within days for users who generate images regularly.
Is Replika’s Lifetime plan worth it?
At $299.99 as a one-time payment versus $19.99 per month, the Lifetime plan pays for itself in approximately 15 months. For users certain they’ll use Replika long-term, it’s the cheapest path over a multi-year horizon. For users still exploring, the annual plan at approximately $5.83 per month is a lower-commitment way to access the full feature set at a reasonable price.
