Why Silas

An AI that reads your documents.
Actually reads them.

Other tools skim a few pages and fill in the gaps with guesses. Silas processes your entire document — every paragraph, table, and figure — so nothing gets missed.

Upload everything. It only gets smarter.

Most tools break down after 20 files. Silas handles thousands without losing accuracy. The more you upload, the more it has to work with.

Ask "show me the architecture diagram" and see the actual figure from your PDF — with a citation. Not just text. The images, charts, and tables too.

Show me the system architecture diagram from the Q3 spec.

Every answer has a source. Or it says so.

Every answer shows exactly where it came from — down to the paragraph. And if it can't find something in your documents, it tells you instead of making things up.
