Who Koimo suits

Chai is a mobile chat app with a large catalog of bots made by its community. Free use is limited and paid tiers unlock more; check its App Store listing or the app itself for current limits.

Koimo is smaller and more curated. Each character has a written premise, a first scene that sets up a clear situation and a calmer alternative start. The free plan is a simple daily allowance: 50 messages a day, resetting each day, with no ads, coins or energy to manage.

Koimo runs in the browser rather than an app store. On a phone you can add it to your home screen so it opens like an app.

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.

Where to start

Browse the characters by genre, read an opening and choose one. If you want a specific personality, write your own character; it stays private to your library.

Long stories use summaries and saved facts to keep continuity, and our continuity guide shows how to keep a long story on track.

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.
