BestChar
An embeddable platform that puts AI characters into a website. Remembering the user and talking with feeling is the point. Names, preferences and what was said are kept as raw conversation in a DB, while semantically similar memories are retrieved from a vector DB and carried into the next turn. Connect the same user and the context follows across a website or an app. One widget line integrates in five minutes; pick among 15+ models (OpenAI, Claude, Gemini) by purpose, or bring your own API key. Voice conversation, multi-character group chat, a knowledge base and ko/en/ja come with it. Planned, built and operated by IbouAI.
