Overview

What is JanitorAI?

Janitor AI is a web and mobile platform for chatting with AI characters and building your own. It is aimed at people who want interactive fiction, roleplay, or ongoing conversation with a fictional persona without having to set up a chatbot themselves.Chats run on Janitor's own model (JLLM) by default, but users can connect an outside model through a proxy or API key, or through the paid janitor+ Router. Creators can add Scripts for triggers, events, and lorebooks, and style character pages with custom CSS.

More about JanitorAI

Do's & Don'ts

Do:

  • Write detailed character definitions for better long chats
  • Connect a cheap external model (e.g., DeepSeek) for higher quality
  • Enable "Allow Proxies" on characters you use with your own API

Don't:

  • Don't expect strong replies from the free model alone
  • Don't skip the help center – proxy setup is technical
  • Don't use without completing age verification if required

Key Features

  • Character creator with personality, scenario, example dialogue, and avatar
  • Built-in JLLM model plus proxy/API-key support for external models
  • Scripts framework for triggers, events, and lorebooks
  • Janitor+ subscription: 5x context, priority replies, monthly swipes on top models
The verdict

Pros & cons

Pros

The character library is far larger than any competitor's, so nearly every genre or scenario already has several characters to try.

The free tier has no daily message cap, which is rare in this category.

Connecting a stronger model through an API key or the Router sharply improves output; characters stay in role and follow long prompts.

Character building goes deeper than rivals, with lorebooks, Scripts, and full CSS control over the bot page.

Moderation is more permissive than Character.AI, so mature and dark themes are allowed under the Limitless tag.

Cons

The default JLLM model repeats itself, speaks for the user, and drifts off the scenario within a dozen or so messages.

Outages and "failed to fetch" errors happen often enough to interrupt longer sessions.

Proxy and API-key setup confuses first-time users, and errors from third-party providers are hard to diagnose.

There is no native voice or image generation.
