🔍
Highlights risky clauses inline
As you browse apartment listings, job postings, and contract PDFs, Main AI silently scans and highlights anything risky directly on the page — no copy-paste required.
⚡
One-click full analysis
See a document you want fully analyzed? One click sends it to Main AI for a complete finding with statute citations, dollar impacts, and ready-to-send letters.
📸
Analyzes screenshots too
Even image-based contracts and lease PDFs that you can't select text from. Capture a screenshot and Main AI reads it — OCR included.
🔒
Private by default
The extension only activates when you click it. It never scans passively in the background or sends data without your explicit action.
