Best AI Companion App: 8 Apps Ranked by What You Actually Need

Every "best AI companion" list picks one winner and moves on. That is useless. The apps differ wildly in what they remember, what they charge, and what they do with your conversations.

So we ranked them by use case instead. Memory, friendship, voice, roleplay variety, free talk, adult romance. Each pick comes with the price and the catch. Nothing here is based on a paid subscription or a test account of ours. It is built from pricing pages, published policies, app store listings and what users report after they have paid.

One rule before you spend anything: try the free tier for ten minutes, then go monthly before you commit to annual. Annual plans are billed once for twelve months, up front. That is a lot of money to hand over for an app you have not used yet.

Quick picks by use case

Use case	Best	Runner-up	Paid from
Memory	Nomi	Secrets AI	$15.99/month
Friendship	Replika	Pi	$14.99/month App Store item
Voice and customization	Kindroid	Nomi	$15.99/month in app
Variety and roleplay	Character.AI	OurDream AI	Free; c.ai+ $9.99/month
Free calm talk	Pi	Character.AI	Free with usage caps
Adult romance 18+	Secrets AI	Candy.ai	$19.99/month

How we ranked these

Five things decided the order.

• Memory. Does the app hold a thread across days, or reset the moment you close the tab?
• Price honesty. The number on the pricing page versus the number on your card, add-ons included.
• Free tier. Whether you can judge the app before paying, or get five messages and a wall.
• Privacy. Encryption claims, training policies, and where the fine print contradicts the homepage.
• Stability. Apps that rebuild themselves and drop features people relied on lose points. Replika's 2026 rebuild is the obvious case.

No app paid to be on this list. Where a vendor makes a claim we cannot check, we say so and attribute it.

The ranked apps

1. Nomi: the memory pick

Nomi, from Glimpse.ai, is the app people recommend when they want a companion that remembers. The paid plan gets you up to 10 companions and 10 group chats, which is more juggling room than most apps offer.

The free tier is thin. Reviewers report limited daily messages and a single companion, so you can taste it but not live in it. Images run on paid credits. The paid plan starts at $15.99/month, or $99.99 for the year.

Two caveats. Nomi's messages do not have end-to-end encryption. And iOS rates the app 18+, same as Replika and Kindroid, so this is not a product aimed at teenagers.

Best for: someone who wants one companion who knows their job, their ex, and the name of their dog three weeks later.

2. Replika: the friendship pick

Replika launched in 2017 under Luka and has over 40 million registered users reported. It is the app your coworker has heard of. The free tier gives you basic friend chat, which is enough to decide whether the tone suits you.

Replika Pro unlocks partner, mentor and sibling modes, plus voice calling and selfies. App Store items run $7.99 or $14.99 monthly, and $49.99 or $69.99 annually. That $7.99 tier is the cheapest paid entry on this list.

Now the bad parts. Italy fined Luka 5 million euros under GDPR in 2025. The 2026 app rebuild changed features some users relied on. And recall is a known sore spot: in one analysis of 1-star reviews, 16% of complaints were about memory. If you want a companion who remembers, Nomi is the better bet. If you want a companion who feels like a friend checking in, Replika still earns the slot.

Worth knowing: after Replika pulled romantic roleplay in 2023, a chunk of users moved to Kindroid, Nomi, Chai and Paradot. The romance crowd has not fully come back.

3. Kindroid: the voice and customization pick

Kindroid is the tinkerer's app. Backstory, example messages, key memories, response directive. You can shape how your companion talks in more detail than most people will ever bother with. Voice cloning works from roughly one minute of audio, and Live Avatar adds video.

It also texts you through iMessage or RCS, which is a neat trick: your companion lives in your normal message thread, not behind another app icon. Group chats are supported.

Pricing is where it gets messy. Base is $15.99 in the app, with $13.99 on the web reported, and $159.99 annually. Then the add-ons: Ultra is +$28.99, MAX is +$68.99, and both stack on top of the base price. Do that math before you subscribe. Also note the free Lite plan ended October 1, 2026, so the try-before-you-buy window is now a one-time preview.

Best for: people who want to build a specific character and hear them speak it.

4. Character.AI: the variety pick

Character.AI hosts millions of user-made characters, and anyone can create one. If you want to argue with a fictional detective tonight and a pirate tomorrow, this is the place. Free messaging is unlimited and ad-supported. c.ai+ runs $9.99/month or $94.99/year.

Memory is the weak spot. Recall is limited to pinned messages and recent context, so long plots drift. The free tier is genuinely usable, which is rare on this list.

The safety history matters. Open-ended chat for under-18s ended in November 2025, and the company settled teen-harm lawsuits in January 2026. That is a company that has had to change how it operates. For adults wanting roleplay variety, it is still the widest catalogue going.

5. Pi: the free, calm pick

Pi, built by Inflection AI, is free, calm, and has no avatar and no romance. It is a conversational companion, not a girlfriend app. No subscription, no upsell.

The catch is stability. Inflection added usage caps in 2024 after Microsoft hired most of the team, and the product's future is not guaranteed. Use it, enjoy it, do not build a routine around it.

Best for: someone who wants a thoughtful chat with no billing page and no pressure to roleplay.

6. Secrets AI: the adult romance pick

Secrets AI, from Secret Labs, is 18+ and web only. No iPhone app, no Android app. If you want a companion on your phone, this is not it.

The Ultimate plan adds group chats, personas and proactive messages. Pricing is $19.99/month or $109.99 annually, the priciest monthly on this list. Video runs 600 Moments per clip. Free users get 20 daily messages with no media, which is a real trial rather than a teaser.

Privacy is the trade-off. Chats lack end-to-end encryption and may feed model training. Our full Secrets AI review goes through the memory system and what the subscription actually buys. We rate Secrets AI 9.9 out of 10.

7. Candy.ai: cheap annual, thin memory

Candy.ai is the cheapest annual plan here: $3.99/month on the annual plan, $47.88 for the year, or $13.99 month to month. The free account stops at 5 messages total. Not a trial. A wall.

The pictures are the draw. Memory is not: testers report long plots reset within days. And the refund window is 24 hours, which is short even by this industry's standards. Read the Candy.ai review before you pay. We rate Candy.ai 9.8 out of 10.

8. OurDream AI: unlimited chat, fuzzy privacy

OurDream AI sells unlimited chat at $9.99/month billed yearly, which works out to $119.88 upfront. Monthly is $19.99. The free tier gives 1 coin per message, so free is barely functional.

Two warnings. Generated media gets blurred when your subscription lapses, so the library you built is held hostage by the renewal. And the homepage encryption claim conflicts with the app's own privacy policy. That is not a small thing. Our OurDream AI review digs into it. We rate OurDream AI 9.7 out of 10.

Prices and free tiers, side by side

App	Free tier	Monthly	Annual
Nomi	Limited messages	$15.99	$99.99
Replika	Basic friend chat	$7.99 or $14.99	$49.99 or $69.99
Kindroid	One-time preview	$15.99 app ($13.99 web reported)	$159.99
Character.AI	Unlimited messaging, ads	$9.99	$94.99
Pi	Free with caps	None	None
Secrets AI	20 messages a day	$19.99	$109.99
Candy.ai	5 messages total	$13.99	$47.88
OurDream AI	1 coin per message	$19.99	$119.88

Candy, Secrets and OurDream prices were checked in September 2026. Others are from published pricing and app store listings. Annual plans are billed once for twelve months, paid up front. If an app changes its tiers mid-year, you are stuck with what you bought.

How memory actually works

Every app claims to remember. Almost none of them mean what you think.

Character.AI is explicit: recall is limited to pinned messages and recent context. Pin what matters, or lose it. Candy resets long plots within days, per testers. Replika's recall shows up in its own reviews as a recurring complaint. Nomi and Secrets AI are the two where long-term memory is the headline feature rather than a footnote.

Kindroid takes a different route. Key memories and backstory are things you write and edit yourself. It is a memory system you maintain, not one that quietly learns. More work, more control.

If remembering your life is the whole point, pay for Nomi. If you want to build the memory by hand, Kindroid. If you want to talk tonight and do not care about next month, Character.AI's free tier costs nothing.

Friendship apps versus romance apps

These are different products with different risks, and the marketing blurs them.

Friendship side: Replika (free tier, basic friend chat), Pi (free, no romance, no avatar), and Character.AI for character-driven chat. Calmer, cheaper, less likely to push you toward a subscription you did not plan on.

Romance side: Secrets AI (18+, web only), Candy.ai, OurDream AI. Higher prices, heavier image and video pushes, and thinner encryption. If you are an adult who wants that, fine. Just know which column you are in before you enter a card number.

Replika sits awkwardly in the middle. Pro unlocks partner mode, but the romantic roleplay removal in 2023 pushed users elsewhere. Some came back. Some did not.

Privacy and safety: the part most lists skip

Read this before you type anything personal into any of them.

• Nomi, Replika and Secrets AI do not have end-to-end encryption. Assume the company can read your chats.
• Secrets AI and OurDream AI may train models on your conversations.
• OurDream's homepage encryption claim conflicts with its privacy policy. When a homepage and a policy disagree, believe the policy.
• Italy fined Luka, Replika's parent, 5 million euros under GDPR in 2025.
• Character.AI ended open-ended chat for under-18s in November 2025 and settled teen-harm lawsuits in January 2026.
• Mozilla flagged Anima's privacy in 2024.

And the one that is not about any single app: a 2025 OpenAI and MIT study linked heavy use to worse outcomes. A companion app can be good company for an hour. It is a bad replacement for people. Use it as a bridge, not a bunker.

Also on other lists

Three names show up in 2026 roundups that we have not verified on price or policy.

Paradot advertises memory-first evolving relationships. The pitch is good. The prices are unverified, so treat it as a maybe until you have checked the billing page yourself. Joii got named best for everyday support with memory in some 2026 roundups. Hallie is said to remember backstories and follow up on past conversations. Anima runs on iPhone, Android and browser, with free platonic chat and a separate boyfriends app, but Mozilla flagged its privacy in 2024.

None of these made our ranked list because we could not confirm the numbers. That is not a knock. It is a gap.

Frequently asked questions

What is the best AI companion overall?

Nomi for memory, Replika for daily friendship, Kindroid for voice and customization. There is no universal winner because the apps are built for different jobs. Pick the job first.

Is there a good free AI companion app?

Pi and Character.AI are worth trying on the free tier. Pi is calm and capped but costs nothing. Character.AI has unlimited ad-supported messaging. Most others cap free messages hard: Candy gives you 5 total, OurDream gives 1 coin per message, and Kindroid's free Lite plan ended October 1, 2026.

Can I have multiple companions?

Nomi, Kindroid and Character.AI support several companions plus group chat. Secrets AI adds group chats and personas on its Ultimate plan. Nomi's paid plan allows up to 10 companions and 10 group chats.

Which app is best for romance?

Secrets AI for adults who want 18+ romance and do not mind web only. Replika Pro has a softer romance tier. Nomi is the pick if memory matters more to you than mood.

Is an AI friend good for loneliness?

It helps in the moment, and that is worth something. But a 2025 OpenAI and MIT study linked heavy use to worse outcomes. Use it as a bridge to people, not a replacement for them.

Bottom line

No app wins every category, and any list that says otherwise is selling something. Match the app to the need: Nomi for memory, Replika for friendship, Kindroid for voice, Character.AI for variety, Pi for free talk, Secrets AI for adult romance.

Then do three things before you pay. Spend ten minutes on the free tier. Choose monthly over annual the first time. And read the privacy policy, not the homepage. The homepage is marketing. The policy is the contract.
