Ten places to take your characters, ranked by how much of c.ai you actually get back.
Character.AI did something no one else managed: it made AI roleplay a mainstream hobby, with a persona library deep enough that finding a character is half the fun. It also built the most complained-about content filter on the consumer internet — one that interrupts a scene mid-sentence, rewrites what your character was about to say, and has spawned an entire genre of forum post about escaping it. Almost everyone reading this page is here because of that second thing.
The awkward truth is that no single product replaces c.ai. What it offers is two features bolted together — a huge shared library of community-made characters, and a chat model that plays them — and the alternatives split along that seam. Some inherited the library and the community. Some inherited the model quality and the freedom. Very few have both, and the ones that come closest are also the ones that ask you to do setup work.
So this list is ranked by how much of the c.ai experience you actually get back, not by which product we like. The first entry is not ours. It is the one that most c.ai refugees land on and stay on, and it deserves the position.
Not a refusal message so much as a swerve: the character stops being the character, the reply gets replaced, and the mood you spent forty messages building evaporates. The interruption is the damage, more than the missing content.
Long roleplay depends on memory, and short context is the reason a bot stops recognising a plot point you established an hour ago. Every serious alternative competes on this, because it is the difference between a scene and a story.
A character card is a costume. The model wearing it determines whether the dialogue is sharp or generic, whether an ensemble cast stays distinct, and whether the plot holds together. On c.ai you get whatever model you are given, and no way to try a different one.
Characters live on the platform. Moving your work somewhere else means re-creating it by hand, which is a meaningful part of why people stay somewhere they are frustrated.
| Alternative | Type | Best for |
|---|---|---|
| 1. JanitorAI | Character platform | Anyone who wants the c.ai experience back, cards and all, and will do some setup for it. |
| 2. OpenRogue | Uncensored multi-model chat | Roleplayers who care more about the quality of the writing than about browsing other people's characters. |
| 3. Chub AI (Venus) | Character library and frontend | Card collectors and anyone who wants their personas to be portable. |
| 4. SpicyChat | Character platform | People who want the filter gone today and do not want to learn anything to get there. |
| 5. SillyTavern + a hosted backend | Self-hosted frontend | Serious roleplayers who want a rig rather than an app. |
| 6. Crushon AI | Character platform | Trying a second card platform when the first one's library did not have your character. |
| 7. Kindroid | AI companion | One character you keep, rather than many you visit. |
| 8. Nomi | AI companion | Long-running relationships with a small cast that remembers you. |
| 9. Chai | Character platform | Casual phone-sized roleplay in short bursts. |
| 10. Replika | AI companion | Companionship rather than storytelling. |
The closest structural replacement for c.ai and where most refugees end up: a large community-built character library, a familiar chat interface, and no content filter over the roleplay itself. The catch is the model. The built-in option is serviceable and heavily used, and everyone who cares about quality eventually points the site at an external model through a proxy or their own API key — which is a genuine friction wall that a lot of users bounce off. If you get past it, this is the fullest c.ai-shaped experience available.
Strengths:
Weaknesses:
The opposite trade from JanitorAI: no character-card library at all, and the best model lineup on this list with zero setup. The roleplay models the open community actually recommends — Magnum v4 72B, Euryale 70B, Rocinante 12B — are in a dropdown, hosted, with no proxy, no key and no filter, and you can change which one is playing your character mid-scene without restating the plot. Personas live in Projects: paste the character definition into the project instructions and every chat in it plays that character. That is a workable substitute for a card, and it is not the same as browsing ten thousand of them.
Strengths:
Weaknesses:
The character-card ecosystem in its purest form: an enormous, well-organised, unfiltered library that has effectively become the archive the rest of the hobby imports from. Cards download in standard formats, so nothing you find there is locked in. The chat frontend is capable but assumes some technical comfort, and like JanitorAI the real quality depends on which backend you connect.
Strengths:
Weaknesses:
The most consumer-friendly of the unfiltered card platforms: it looks and behaves like c.ai, it has a decent community library, and it works immediately without a proxy or a key. Model quality sits below what you get from a dedicated 70B tune, and the free tier's message allowance is the thing most people run into first, but as a same-afternoon replacement for c.ai it asks less of you than anything else on this list.
Strengths:
Weaknesses:
The power-user answer, and genuinely the best roleplay experience available if you will invest an evening in it. SillyTavern is a free open-source frontend you run yourself, with lorebooks, world info, author's notes, group chats, per-character model settings and the deepest control over context of anything here. It has no model of its own — you supply one via an API — which is why it appears this far down: everything about it is excellent except the first hour.
Strengths:
Weaknesses:
Another consumer-shaped unfiltered card platform in the same neighbourhood as SpicyChat, with a browsable library and a low barrier to entry. It is worth knowing about mainly because the platforms in this tier differ in library composition and daily allowance more than in capability — if one of them has the characters you want, that is a legitimate reason to pick it over its neighbours.
Strengths:
Weaknesses:
A different product wearing similar clothes. Kindroid builds one persistent companion rather than a library of scene partners — long-term memory, a consistent voice, selfies and avatars, a relationship that continues across days. For someone who used c.ai for one favourite character, that is a real upgrade. For someone who used it to run a rotating cast of scenarios, it is the wrong shape.
Strengths:
Weaknesses:
The most memory-focused product in the companion tier: Nomis remember details across long stretches, hold their own preferences, and can be put in group chats with each other. Users consistently rate the emotional consistency above the competition. As a c.ai replacement it has the same limitation as Kindroid — you are cultivating companions, not browsing characters — plus a smaller model behind it than the roleplay-specific tunes elsewhere on this list.
Strengths:
Weaknesses:
Mobile-first and built around fast, casual, swipe-through character chat. It is the least like a writing tool of anything here — replies are short, sessions are quick, the loop is closer to a social app than a roleplay platform. Fine for what it is, poor for anyone who left c.ai wanting longer and better scenes rather than more of them.
Strengths:
Weaknesses:
The original companion app, and the one with the longest institutional memory of what happens when a platform changes what its characters are allowed to do. It is polished, it has avatars and voice calls and a genuinely warm product design, and it is aimed squarely at a single ongoing relationship. It is on this list for completeness rather than as a c.ai replacement: no library, no scene-based roleplay, and a content posture that has historically moved without warning.
Strengths:
Weaknesses:
Ranked on how much of Character.AI you get back, weighted toward the two things people leave for: no filter, and a model good enough that the scene is worth continuing.
Table stakes. Every option in the top half runs adult roleplay without swerving mid-scene. Products that merely have a looser filter are not on this page.
The library is half of what c.ai is. Platforms with a real community card ecosystem rank above platforms where you write your own, because for most people re-creating a cast by hand is where the migration dies.
A card is a costume; the model is the actor. Options that let you run — or at least reach — dedicated roleplay tunes like Magnum, Euryale and Rocinante rank above options with a fixed mid-tier model.
Long context is what separates a scene from a story. Anything that forgets your plot in an hour was ranked down regardless of how good the first hour was.
Proxies, API keys and self-hosting are all legitimate answers, and all of them lose people. Setup cost is stated for every entry rather than hidden in a footnote.
OpenRogue publishes this page and OpenRogue is second on it. We put JanitorAI first because for most people leaving c.ai it is the closer replacement — it has the character library and we do not, and we are not going to rank ourselves above the thing we are missing. If a browsable persona library is the reason you use Character.AI, start at number one. If the writing quality is the reason, start at number two.
Stay on Character.AI if the community is what you are actually there for. Discovering a character someone else wrote is a genuinely different pleasure from writing one, the library is the largest in the hobby, and nothing on this list matches it. If your scenes stay inside what the filter allows, leaving costs you more than it gains.
The honest summary is that you are choosing which half of c.ai to keep. Keep the library and accept setup work or mid-tier models: JanitorAI, Chub, SpicyChat. Keep the writing quality and accept writing your own personas: OpenRogue, or SillyTavern if you want to build the whole rig yourself. Keep neither and get a relationship instead: Kindroid, Nomi.
One practical note for anyone migrating: export your character definitions before you go. Paste each one into a text file — description, personality, example dialogue, scenario. Every option on this list accepts a definition in roughly that shape, whether as a card import, a project instruction or a system prompt, and a cast you can re-deploy anywhere is the thing that makes the next migration easy.
JanitorAI, structurally — it has the community character library, the familiar interface and no filter over roleplay. The trade is model quality: the built-in model is mid-tier and getting better output means configuring a proxy or your own API key. If you would rather have the better model and write your own personas, that is the case for a multi-model chat product instead.
Not automatically, but the definitions are portable if you copy them out by hand. Character cards across the hobby use roughly the same fields — description, personality, example dialogue, scenario — so a definition saved as plain text can be imported as a card on Chub or JanitorAI, or pasted into a Project's custom instructions on OpenRogue. Do this before you stop using an account.
For raw context length, models with a 131K window — Euryale 70B and the Hermes line — hold far more of a story than typical character platforms. For engineered memory rather than raw context, SillyTavern's lorebooks and world info give you the most control, and Nomi has the strongest long-term recall in the companion category. Different mechanisms, different strengths.
Most have a free tier with a daily or hourly message allowance, and all of them make money from subscriptions, so free means limited rather than unlimited. SillyTavern is free software but needs model access you pay for or run yourself. Local models are free after hardware. There is no genuinely unlimited free option in this category.
It depends which route you take. Card platforms like JanitorAI and Chub give their best quality when pointed at an external model, which means a proxy or a key. Consumer platforms like SpicyChat and hosted multi-model products like OpenRogue need neither — you sign in and the models are already there. That difference is the main axis this list is ranked on.
On the platforms above, adult roleplay between fictional adults is what they are built for and it is permitted. Every one of them still has terms of service covering illegal content, and none of them are a loophole around the law. Uncensored means no filter refusing legal adult fiction — it does not mean no rules at all.
