Chat with a PDF for free, no sign-up
Klaizon lets you chat with a PDF for free: attach the document, then ask for a summary, a specific clause, the deadlines, or anything you don't understand in plain English. It also reads Word files and spreadsheets. There is no sign-up, the file is opened in your own browser, and nothing is stored on our server.

How do I ask questions about a PDF?
- Attach the file with the paperclip: PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx) or CSV, or a photo or screenshot of the page.
- Ask anything: “Summarise this in five bullets”, “What happens if I end the lease early?”, “List every date in here”.
- Ask for a file back if useful: “Make me a one-page summary PDF”.
What kinds of documents work best?
Anything with real text in it: contracts, leases, policies, papers, manuals, reports, statements. A scanned page has no text to pull out, so attach it as a photo or screenshot instead (up to three at a time) and Klaizon reads it as a picture.
Is my document uploaded anywhere?
The file is opened inside your browser, not uploaded to Klaizon for storage. The text needed to answer your question is sent with your message to the AI, as with any question, and is not kept by our server. The file itself stays in your browser's Files panel until you delete it.
How long can the document be?
Klaizon reads around 48,000 characters of text per message, roughly 20 to 24 pages. For a longer document, ask about one section at a time.
