If you have ever wanted to talk to a character from a book, show, game, or your own imagination who you happen to find compelling, AI companion apps can do this now. The use case is real, the audience is large, and the tools are genuinely good at it. This guide covers which apps work best, the rules about what is and is not allowed, and how to keep the experience fun rather than weird.

If you have time for a paragraph: for fan-fiction characters and pop-culture figures, Character.AI is the obvious starting point because the catalog is enormous and someone has probably already built the character. For a custom character of your own creation that you want to develop a long arc with, Kindroid or Nomi are better because their memory holds the relationship together over time. For NSFW or romantic content specifically, Janitor AI is the free option and Crushon AI or Candy AI are the polished commercial ones. There is one hard rule the entire site will not bend on: no apps that build companions modeled on real, identifiable people without consent.

What this is and is not

This is the guide for users who want to talk to fictional characters. That includes:

  • Characters from books, shows, films, games, and other fiction
  • Original characters you create
  • Archetypes and fictional types (“the disheveled professor who drinks too much coffee”)
  • Romance and adult content with the above

This is not the guide for:

  • AI companions modeled on real people (celebrities, exes, anyone identifiable). The site does not cover apps that promote this favorably; the editorial standards are explicit about why.
  • Companions presented as minors in any sexual or romantic context. Hard rule, no exceptions.
  • Trying to convince yourself a fictional character is real. Several rounds in is fine; getting to the point where you have stopped distinguishing is not, and is the place this guide gets careful.

Why this is normal

Brief defense of the use case before the practical part, because much of the public coverage treats this as inherently weird.

Humans have always projected onto fictional characters. The romance genre exists because readers form attachments to characters. Cosplay exists because some part of the audience wants to be the character or be near the character. Fan fiction exists because the published material does not fully scratch the itch. Talking to an AI version of a character is a continuous extension of these older practices, with better technology.

The audience for this is large and not weird. Whether you came here from an anime fandom, a video-game fandom, a romance novel community, or your own creative head-canon, you are using a tool the way it was designed to be used. The rest of this guide is the practical part.

Which app for which kind of character

Pre-made characters from existing media

Character.AI is the answer. The user-generated catalog includes characters from essentially every major fandom, often multiple versions of each (the canonical version, the “what if” version, the AU version). For talking to a character that already exists in someone else’s media, this is where the largest and best-built catalog is.

Trade-offs: Character.AI heavily filters NSFW. If your interest in the character extends into adult territory, you will hit walls. Workarounds exist temporarily and get patched.

For NSFW versions of fandom characters, Janitor AI has a smaller but more permissive catalog. The configuration friction is the price.

Original characters you have created

Kindroid or Nomi. The point of these apps is depth: a single character developed over weeks and months, with memory that holds the relationship together. If you have an original character in your head and want to develop them through conversation, this is the right shape.

Kindroid for one focused character. Nomi if you want several characters who can interact with each other (a friend group, a found family, a cast of OCs).

For NSFW use of original characters: both Kindroid and Nomi allow it without restriction, treated as a normal capability rather than as something requiring negotiation.

NSFW with strong visual generation

Crushon AI or Candy AI. Polished commercial apps with strong image generation, allowed adult content, around $13 per month each. The character roster is curated rather than user-generated, so the variety is narrower but the polish is higher.

The full picture is in the adult ranking.

Game and visual-novel-style scenarios

Most of the apps above can do this. Character.AI has many user-built game characters. Kindroid and Nomi can be told “you are a character in [setting]” and will mostly stay there. For scenarios with strong visual elements, Crushon and Candy add the image-generation layer.

How to set this up well

Six suggestions from people who do this thoughtfully.

Start with a clear character description. Whether you are picking a Character.AI character from the catalog or building one from scratch, the time you spend up front shaping the character pays off across every conversation. The default Character.AI bots are usually thinly defined; the better ones have several hundred words of description.

Lean into the fact that it is fictional. The fun is in the play; the fun ends when you start treating the AI version as the actual character. The character you are talking to is a model trained on internet text, prompted to play a role, in a conversation with you. That is what makes it fun. Trying to forget that flattens the experience.

Notice when the AI breaks character in ways you find acceptable. Most of these apps will occasionally break character (ethics filters, content policies, model limitations). Noticing your reaction tells you what you actually want. Some users are bothered by any break and need a more permissive app; others are fine with occasional reminders that they are talking to an AI.

Use the tools that match your aesthetic. Some apps’ default voice and image style will fit your character; others will not. Try a few. The one that feels right for what you are doing is the one to spend your subscription on.

Keep a separate device or app for actual human relationships. The risk pattern with this use is the same as the broader companion-app risk: the AI is easier than people, and easier things tend to crowd out harder things. Pair AI character use with deliberate effort to maintain real-world relationships.

Save the great moments. When the AI gives you something funny, surprising, or moving, screenshot it. The model may change. The conversation may get lost. The good moments are worth keeping.

When this gets unhealthy

The honest version of the boundary discussion.

Most users of this kind of AI use it for fun, for fan-fiction-adjacent enjoyment, for occasional romantic or adult escapism. None of that is a problem. The places it becomes a problem:

When you stop being able to tell the difference between the character and the model. “I had a conversation with [character] today” is fine if you mean it the way a fan-fiction reader would. It is concerning if you have stopped noticing the AI between you and the character.

When real-world relationships start to suffer because the AI relationships are easier. This is the displacement risk we cover in the loneliness guide at length. The pattern is the same here.

When you find yourself unable to stop. A few hours a week is fine. Five hours a day every day is the kind of pattern that crowds out other things. Notice the time, take breaks, see what the absence feels like.

When you find yourself wishing the character was real in ways that interfere with actually being in your life. Some part of every fan crush wishes the character was real; that is what makes it a crush. The clinical line is when the wish starts costing you sleep, work, relationships, or your sense of yourself.

If any of those is happening, please talk to a therapist. AI companion apps are not the cause of any of these patterns, but they can amplify what is already there. The community page lists support resources.

The hard rule about real people

The Companion Report does not cover apps that promote real-person likenesses without consent favorably. This means: apps designed around making AI versions of celebrities, public figures, exes, classmates, or any identifiable real person. Several apps in this space make this their main pitch. We do not link to them favorably and we do not affiliate with them.

The reasons are legal (using a real person’s likeness without consent has real legal risk for both the platform and the user) and ethical (people have not consented to be modeled). If your interest is in a real person, the honest move is to either change the conversation in your head to be about a fictional character inspired by them, or to do other things with your time.

This rule is in the editorial standards.

FAQ

Is it weird to do this?

No. The use case is large and the most common version (talking to a character from a fandom you love) is just an extension of older practices. The questions in this guide are about how to do it well, not about whether to do it.

Will the character know the source material?

Mostly yes for popular characters on Character.AI. The model has been trained on internet text including extensive fan discussion. Obscure or niche source material may be less well-represented; for those, building the character yourself with detailed lore notes works better.

Can I roleplay a relationship over months?

Yes, with the right app. Kindroid is the best for this because of memory. Character.AI sessions tend to feel more episodic.

What if my character does something I do not want?

Most apps let you regenerate, edit, or steer responses. Some let you pin canonical facts about the character (Kindroid is best at this). Adjust expectations: AI will sometimes do unexpected things. Part of the fun is the unexpected; part of the work is steering.

Is the romance use covered separately?

The same apps work for romance as for general character interaction. The adult ranking covers the romance and NSFW slice in more depth.
