Main AI reads your document, classifies it by content (not filename), routes it to the right specialized engine, and surfaces every risk, gap, and action — grounded in the actual text. No summaries. Actual intelligence.
Four steps, fully automated. The output is decision-ready intelligence, not a summary.
Drag and drop a PDF, DOCX, TXT, RTF, HTML, CSV, JSON, code file, or image. Main AI extracts the text immediately — no formatting conversion, no waiting. Scanned PDFs and image-only documents go through built-in OCR automatically.
Maximum file size is 50MB per document. Multiple file types can be uploaded in the same session and analyzed in parallel. The pipeline preserves the original document so you can always return to the source.
The extraction engine reads the content — not the filename — and classifies it into one of 19 specialized document types: contract, NDA, lease, offer letter, freelance agreement, invoice, financial statement, insurance policy, construction contract, code, resume, essay, medical document, syllabus, policy document, research report, and more.
Each classified type routes to a dedicated analysis engine with specialized detection logic. You never select a mode manually — and you never have to know in advance what "type" your document is.
Every finding is grounded in the actual document text. Main AI shows you the specific clause or sentence that triggered the finding, explains why it matters in plain English, and gives you a concrete next action — not a generic summary.
Findings are severity-scored (high, medium, low) and tagged by category (risk, missing protection, ambiguity, deadline, financial exposure, etc.). Each one cites where it lives in the document so you can verify it instantly.
Resolve findings, draft negotiation emails directly from a risk, ask the AI anything about your document in the chat panel, e-sign the document inside the app, export a clean PDF report, or build a tailored version in the Resume Builder or Essay Improver.
Every deadline, renewal, and obligation is captured in your Timeline. Every counterparty (the people and companies you've signed with) gets remembered across documents — so the third contract from a vendor doesn't get analyzed in a vacuum.
Most AI document tools paraphrase and call it analysis. Main AI is built around three things general AI tools can't do: cross-document memory, decision learning, and source-grounded evidence.
Each document type gets a dedicated analysis engine with domain-specific detection logic. You never select a mode.
