Key point

Open-sourced a web-search Research agent and a document chatbot Support agent.

Two agents have been open-sourced.

Research agent: Searches the web and returns answers as streaming, attaching sources. It aims for search-style responses like Perplexity.
Support agent: When you upload documents, it works as a chatbot that includes citation.

Both agents run on OnCell, with isolated storage, database, and search separated per user.

The backend implementation for each is composed of just one file, a notable feature that keeps the structure simple.
