Use Cases

📄

Research Papers

Upload academic papers and ask for key findings, methodology critique, or summarize specific sections without re-reading the whole thing.

📋

Contracts & Legal Docs

Upload contracts, NDAs, or terms of service. Ask "What are the termination clauses?" or "Summarize my obligations in plain English."

📊

Reports & Whitepapers

Upload annual reports, market analyses, or product specs. Extract key metrics, compare sections, or create executive summaries instantly.

📖

Manuals & Documentation

Upload technical manuals, API docs, or user guides. Ask specific questions instead of searching through hundreds of pages.

Frequently Asked Questions

Is my PDF data safe? expand_more
Your PDF is processed entirely in server memory and is never saved to disk. Extracted text is sent to the AI model (OpenAI) for processing but is never stored. For large PDFs, a temporary session is created that automatically expires after 30 minutes of inactivity (or 2 hours maximum).
What types of PDFs are supported? expand_more
Any text-based PDF up to 10 MB: reports, contracts, research papers, manuals, invoices, specifications, and more. Scanned or image-only PDFs are not currently supported — the PDF must contain selectable text.
How does it handle large PDFs? expand_more
Small PDFs (under ~40 pages) use full context injection — the AI sees the entire document for maximum accuracy. Larger PDFs automatically use vector search, which intelligently finds the most relevant sections to answer each question.
How many messages can I send per day? expand_more
You can send up to 20 messages per day for free. The quota resets at midnight and is shared across all AI chat tools. Your remaining message count is shown at the top of the page.
