SillyTavern alternative: hosted, no setup

Koimo is a hosted SillyTavern alternative: no install, no API keys and no model to choose. Import your Character Card V2/V3 files and SillyTavern chats, chat in any browser, and export them back whenever you like.

Who Koimo suits

SillyTavern is a locally installed interface for character cards that connects to a model backend you choose and configure. It is very flexible, and its cost, privacy and quality depend on the setup you build.

Koimo is for the times you don’t want to run that setup: on your phone, on a borrowed computer, or when you just want to chat. Everything is hosted, and the model, prompt and memory are handled for you. You give up control over the model and sampler settings in return.

Koimo is 18+ and explicit scenes fade to black, which also differs from an unrestricted local setup.

Bring your cards and chats

  1. Open the import tool and choose your character cards (V2/V3 PNG or JSON) and SillyTavern .jsonl chats.
  2. Check the preview. Conversion runs on your device; nothing is uploaded until you choose to save to your library.
  3. Save the characters and chats you want, then continue a chat or start a new one.

A different model can read the same card differently. Start with a short recap of the scene. Export at any time to get V2/V3 cards and JSONL chats back for SillyTavern.

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.

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.
