Who it's for

For SillyTavern users who want a browser-based setup

Many people who write with AI characters started on SillyTavern and now want their cards and lorebooks in a browser, without a local install. Moving that collection by hand is slow and easy to get wrong. They also want to keep using their own API keys and favorite models instead of being locked into one.
