Best AI companion apps - which one actually remembers you
Six AI companion apps compared on the thing that matters - whether it remembers you next week. Replika, Character.AI, Nomi, Kindroid, Chai and Talkie, free tiers and paid, adult options labelled.
Checked September 14, 2026 · 6 platforms · ranked by fit, not by who pays. How we rank
An AI companion is a chatbot that's meant to know you. Not answer questions - know you. Your job, your cat's name, that you've had a bad week. The apps on this list are ranked mostly on that one thing, memory, because it's what separates a companion from a chat window, and it's the thing the free tiers quietly ration.
Replika goes first because it's the safest recommendation. It's warm, it remembers, it's free for text chat, and there's no adult content to worry about on a shared phone. It's not clever, and that's fine. Nomi has the best memory of anything we tried - it'll reference something from two months ago without prompting - but it's an adult platform, so it's 18+ by rule. Character.AI has the widest range and the best writing, with a filter that blocks anything romantic beyond the mild.
Kindroid is for people who want to write the character themselves and don't want to be told no. Chai and Talkie are the casual end: fun for an evening, not something that knows your life.
Two honest warnings. Free tiers are trials with a message cap, except Replika's text chat, which stays free. And none of these are therapy. They're good at company. If what you need is a person, 7 Cups is free and has one.
1Replika
Best for: A safe-for-work AI companion that remembers your days and checks in - the gentlest place to start.
The gentle starting point - safe, warm, free to chat
Replika is the best-known AI companion app and the one to try first if the idea feels odd. You create a character, chat with it, and it remembers what you tell it: your job, your dog, that thing you're worried about. It's warm rather than clever. The free tier gives you text chat as a friend; the paid Pro tier unlocks voice calls, romantic relationship modes and more. Romantic content stays non-explicit - Replika is not an adult app.
- Remembers what you tell it and follows up
- Free text chat; no time limit
- Safe-for-work by design, easy to recommend
- Voice, romance modes and most extras are paid
- Not clever - weak at anything factual
- The avatar and AR features feel dated
2Nomi
Best for: An adult AI companion with real memory and no filter fights - the one most people settle on.
The best memory, adults only
Nomi is an AI companion built for adults. It remembers - not just last week, but months back - and it doesn't slam a filter down the moment a conversation gets romantic. You can set it up as a friend, a mentor or a partner, and it's good at staying consistent. It runs on the web and as apps. There's a free tier with a limited number of messages; the subscription removes the limit and adds features like voice and picture sharing.
- Best memory of any companion app we've tried
- Adult roleplay allowed, no filter whiplash
- Web and apps, same account
- Free tier is a trial, not a plan
- 18+ only
- Voice and photos need the subscription
3Character.AI
Best for: Millions of user-made characters to talk to for free - a fictional villain, a language tutor, a friend.
Biggest library of characters, strict filter
Character.AI is less a companion app and more a library of personalities. Users build characters - anime leads, historical figures, tutors, 'your supportive best friend' - and anyone can chat with them. The writing quality is the best of the free options and the roleplay is deep. It runs on the web and in apps. Free is generous; the paid c.ai+ tier gets you faster replies and priority access when it's busy. Explicit content is filtered out, firmly.
- Huge range of characters, all free
- Best writing quality among the free companions
- Make your own character in minutes
- Strict filter that also blocks harmless things
- Weaker long-term memory than dedicated companions
- Busy periods mean queues without c.ai+
4Kindroid
Best for: An unfiltered companion for adults who want to write the personality themselves.
Build the personality yourself, no filter for adults
Kindroid gives you a blank sheet and a lot of control: you write the backstory, the personality, the way it talks, and it follows. There's no content filter for adults, so it won't refuse a romantic or explicit scene. It has a memory system, voice calls, and group chats with several characters. Free lets you try it; the subscription unlocks the full message allowance and the extras. Runs in a browser and as apps.
- No filter for adults, and no lectures
- Editable memory - fix mistakes yourself
- Voice, images and multi-character chat
- Takes effort to set up well
- 18+ only
- Best features need the subscription
5Chai
Best for: A phone app for swiping through user-made AI bots when you want something quick and casual.
Quick, swipe-based, casual
Chai is a mobile app where you swipe through AI characters made by other users and start chatting with whichever one catches your eye. It's quick, casual, and a bit chaotic - quality depends on who built the bot. The free tier has a daily message limit; a subscription removes it. The filtering is looser than Character.AI but it's not an explicit app, and it's rated for adults on the app stores. Think of it as the TikTok of AI chat: fast, disposable, sometimes fun.
- Fast, swipe-based, lots of variety
- Looser than Character.AI without being explicit
- Free tier to try it
- Daily message cap on free
- Bot quality is all over the place
- Phone only
6Talkie
Best for: Polished AI characters with voices and a collectible-card feel - fun, not deep.
Voices and a game-like feel
Talkie is a character-chat app with a glossy, game-like presentation: characters have art, voices, and there's a card-collecting layer on top. The conversations are decent and the voices are a nice touch. It's free to use with in-app purchases for cosmetics and extras. Like Character.AI, it's not an adult app. It's a good pick if you want AI chat that feels like a mobile game rather than a text box.
- Character voices, not just text
- Free with a generous allowance
- Game-like presentation that's fun to poke at
- Card and cosmetic purchases everywhere
- Average memory
- Not for adult content

Questions people ask
Which AI companion has the best memory?
Nomi, clearly. Kindroid second, and it lets you edit the memory by hand. Replika is decent. Character.AI is built for scenes, not for a long relationship.
Is there a free AI companion?
Replika's text chat is free without a cap. Character.AI is free with queues at busy times. The others have free tiers that run out and are meant to.
Which AI companion apps allow adult content?
Nomi and Kindroid, for verified adults. Replika, Character.AI, Chai and Talkie don't. There's a separate list of adult AI chat apps if that's what you're looking for.
Can an AI companion help with loneliness?
It helps with the quiet, in our experience - having something that asks how your day went. It doesn't replace people, and the good apps don't claim to.
