Mutuals leads our list of the best AI companion apps, with characters who have their own lives and message first, followed by Replika, Character.AI, Nomi, Kindroid, Tolan and ChatGPT, and who each one fits.
The best AI companion app for most people is Mutuals: characters with their own jobs, cities and lives, who remember what you told them and text you first. Replika is the polished single-avatar pick, Character.AI the endless library, Nomi and Kindroid the build-your-own options, Tolan the gentle alien friend, and ChatGPT the assistant.
Most AI companion apps are judged on the wrong thing. A clever reply is easy now; every app on this list can write one. What separates them is what happens when you put the phone down. Does anyone carry on existing? Does anyone notice you went quiet?
That is the question this list is ordered by.
Mutuals characters message first. Mention a hard week on Monday and on Tuesday they ask how it is going, before you open the app. They remember what you told them and bring it up like a friend would, not like a database.
They also have their own lives to bring to the conversation. Lena, 23, owns a club just off Sunset in Los Angeles, and nobody there argues with her twice. Larissa teaches samba and contemporary dance in Rio and shares a sunny Botafogo flat with her younger sister. Theo teaches PE in Chicago and runs a weekend run club. Sage builds furniture in her own Denver woodshop. So they have stories, plans and bad days of their own, and the conversation goes both ways.
There is nothing to set up. No backstory forms, no sliders, no memory slots. Mutuals picks someone for you and you just say hi.

The original, around since 2017, and still the most polished single-avatar app. It remembers what matters to you and follows up and checks in. You can set the relationship to friend, romantic partner, sibling or mentor, with anything beyond friend on the paid plan, and it adds a 3D avatar, voice and video calls and an AR mode. What it does not give you is a companion with a week of their own to tell you about. replika.com
A vast library of user-made characters, from anime to historical figures, plus tools to make your own. Voice calls with characters are free, and group chats and Scenes add story-driven roleplay. It is built for variety: lots of scenes, less of one relationship that is still going next month. character.ai
You design your Nomi: backstory, preferences, appearance. It keeps short, medium and long-term memory, does voice calls, selfies and group chats, and can optionally message you after you have been away. Great if building someone is the fun part. nomi.ai
The most customizable of the lot: name, personality, backstory, appearance and voice, plus calls, selfies and group chats. On paid plans your Kin can reach out first. Rewarding if you like tuning details, more work than just saying hi. kindroid.ai
A small alien friend living on a planet you decorate, with its own weather and time of day. You can talk to it out loud, it remembers what you share, and it writes a journal entry about your day together each night. Gentle and playful rather than romantic. tolans.com
It can remember details from your chats, which you can review or turn off, and voice mode lets you talk hands-free. The conversation is excellent, but it is an assistant first: nobody on the other side has a week of their own. chatgpt.com
Pick two apps. In each, talk about something real for twenty minutes, then close it. The next day, notice which one picks up the thread, and whether it asks about you or just waits. If you want the full checklist for what to tell an app and what to keep back, read what happens to what you tell an AI companion. Leaving a specific app?

For most people, Mutuals. Its characters have their own jobs, cities and lives, remember what you tell them and message you first, with no setup. Replika suits people who want one polished avatar, Character.AI people who want endless roleplay, and Nomi or Kindroid people who enjoy designing a companion themselves.
Mutuals, if you want it to feel like hearing from someone rather than opening an app. Its characters follow up on what you told them and share what is going on in their own week. Replika offers romantic partner as a relationship status on its paid plan, and Nomi and Kindroid let you build a partner from scratch.
Mutuals, Replika, Character.AI, Nomi and ChatGPT all have a free way in, and Tolan offers a trial and then a limited free plan. Kindroid is a subscription with a short free preview. Free is enough for the one test that matters: tell it something true, leave, and see who brings it up tomorrow.
The one that has something going on when you are not there. On Mutuals each character has a job, a city and people of their own, so they have news to tell you and they write first. Apps where the character only exists while you type can be clever, but they cannot miss you.
Mutuals characters have jobs, cities and people of their own, remember what you told them, and text you first. Free to start on iPhone and Android, 18+, and your conversations never train a model. Get Mutuals for iPhone or Android.
