Janitor AI alternative: story-led character chat

Koimo is a Janitor AI alternative for people who want story-led character chat that works without proxies or API keys: an original cast, fan characters and your own characters, with 50 free messages a day. It is 18+ and explicit scenes fade to black.

Who Koimo suits

Janitor AI is a browser-based character chat site built around a large library of community-made characters. Its help centre explains how to chat with its own model or connect your own API key through a proxy setting, which gives you control but means setting up and paying for a provider yourself.

Koimo takes the other approach. There is nothing to configure: you pick a character and start. Every Koimo original and fan character is written as a full story premise, with a concrete opening scene and a calmer alternative start, instead of a short bio.

If explicit roleplay is what you want, Koimo is the wrong fit: romance is welcome, but explicit scenes fade to black. Choose Koimo for slow-burn romance, fantasy, mystery and cozy stories that stay in character.

What you get on Koimo

  • Free: 50 messages a day, no ads and no in-app currency.
  • Plus: $7.99/month for 150 messages a day and a longer story context. Compare plans.
  • Characters: an original cast and unofficial fan characters, plus your own private characters.
  • Portable: import supported Character Card V2/V3 files and SillyTavern chats; export your characters and chats in open formats.
  • Boundaries: adults 18+ only, and explicit scenes fade to black. See the content policy.
  • Where: in the browser on any device, and installable as a web app on iPhone, Android and desktop.

Chats keep running summaries and facts so a long story can refer back to earlier events. That helps continuity, but no memory system recalls every message word for word.

Bring a character with you

If you have a character as a Character Card V2 or V3 file (PNG or JSON), import it to your private library. Our card viewer shows what a card contains before you upload anything, and the card creator helps you write one from scratch.

A card holds the character, not your past conversation. Start an imported character with a short recap of where the story stands.

Whatever you try, test it with one short scene: give the character a place and a problem, disagree once, and mention a small detail you bring back a few messages later. Whether the character keeps its voice, leaves your actions to you and remembers the detail tells you more than any list of features.
