All features

Everything Chatvia does, in one place.

The self-hosted AI agent platform for teams. Free on your own server, with no limits on agents or replies. A license adds more workspaces, the API, voice and Live Chat.

Knowledge and search

Your knowledge, found in a blink.

Agents answer from your own documents, websites and Q&A.

  • Files of every kind

    PDF, Word, PowerPoint, Excel, CSV, EPUB, Markdown and images. Read in the background while you watch the progress live.

    Read the docs

  • Website import

    Find the pages of a site, pick the ones you want, and refresh them daily, weekly or monthly.

    Read the docs

  • Hybrid search

    Vector search and BM25 keyword search run side by side inside PostgreSQL. No extra database to run.

Q&A pairs

Write the exact answer to a question. Fix a weak answer from the chat log and it becomes a Q&A pair.

Reranking

A reranker puts the best passages first, with Cohere, OpenRouter or your own server.

Each part of a document gets a summary and the questions it answers, so agents find the right part.
