Search for a free AI companion and you get a wall of apps that all say "free" in the title. Most of them are free the way a gym's first week is free. That is fine, as long as you know what you are getting before you get attached.
This guide goes through what five popular companion apps actually give you for free, what costs extra, and how to spot the apps whose "free forever" promise is paid for some other way. One honesty note first: we make one of these apps, Aisha. We describe the others using what each company says about its own product, and we skip exact prices because they change too often to stay accurate.
Why "free forever" is rare
A companion that remembers your week, answers in a voice and sends you a photo is expensive to run. Every reply is a call to a large AI model, and long memory means feeding it more of your history each time. Somebody pays for that.
So a companion app usually does one of three things:
- Free to start, then a plan. You get enough to judge it, then pay for more. This is the honest version.
- Free with limits that never lift. Slower replies, shorter memory, no voice.
- "Free forever" with ads or data. The app pays for itself by showing you ads or sharing what you tell it. Read the data-safety section before you trust one of these with your secrets.
None of these is automatically bad. The problem is not knowing which one you signed up for.
What each app gives you for free
Character.AI
The most generous free use on this list. You can chat with thousands of characters made by other users, from anime personas to historical figures, without paying. There is an optional subscription, c.ai+, for extras.
The catch is that it is built for variety, not one companion who knows you over months. Memory and continuity are weaker than in apps made for a single long relationship, the content filters are strict, and the company has restricted open-ended chat for users under 18.
Free is best for: roleplay and variety.
Nomi
Nomi says it is free to start chatting with no credit card required. Its pitch is memory, with short, medium and long-term recall, and you choose whether your Nomi is a friend, a mentor or a partner. Unlimited use needs a subscription.
Free is best for: testing whether its memory works for you before you pay.
Kindroid
Kindroid describes itself as a subscription service, and new accounts can try it before subscribing. You build your own companion, a "Kin", down to backstory, look and voice, and subscribers get a longer working memory of your recent chats.
Free is best for: a short test drive of the character builder.
Replika
Replika is free to start. According to recent reviews, voice calls and most of the extras sit behind its paid tier, so the free version is mostly text chat.
Free is best for: seeing whether the best-known companion app suits you.
Aisha
Aisha is free to start, with a limited amount of free chat, and no card needed. She is one character built for depth instead of variety: she builds her own picture of you, carries your story on from day to day, and the decisions you make change her life and your life with her. She also texts first.
Ludo with her is free for everyone, a full game across the table, and you can try a movie night together, where you pick something to watch and she reacts as it plays. Voice notes, voice calls and photos are part of the paid plans. When you want more, plans in India start from a ₹49 Day Pass, and outside India you can pay by card.
Free is best for: finding out in a few days whether a companion with her own life feels different.

How to get the most out of a free start
You only get one first impression with each app, so test the thing that matters:
- Tell it something specific on day one, like "I have a job interview on Thursday".
- Talk normally and notice whether the replies feel natural or scripted.
- Come back two days later and see whether it remembers the interview without being reminded.
- Before you pay, check whether the plan renews automatically and how to cancel.
If an app fails step three on the free tier, paying will rarely fix it.
Red flags to avoid
- "Unlimited free" companion apps with no clear business model. Something is paying for it, often your data.
- Modded or "free unlocked" APKs. They come from outside the official stores, can carry malware, and still ask for personal information.
- Apps that ask for contacts, location or photos on day one without a reason you can see.
- No privacy policy, or one you cannot find. Skip it.
The bottom line
There is no truly free companion that remembers you and calls you, because someone has to pay for the AI behind it. What you can get for free is a fair trial. Use it to test memory and personality, and only pay for the one that passes.
