More than a summary.

Give it a document. Get back structure.

KeyLen AI works on PDFs. You choose one; the app extracts its text on your device and sends that text to be analysed. What comes back is organised — not another wall of prose to read.

It is built for the documents people actually have to work through: product manuals, annual reports, technical papers, proposals.

Quick, or deep.

Quick Analysis takes a document in one pass and returns the essentials — summary, key points, risks and recommendations.

Deep Analysis applies a specialised method to a particular kind of document, such as Product Insights for product manuals and solution documents. It returns a longer, structured report.

Deep Analysis is part of the trial and Pro. It is not included in the free tier.

Four things, every time.

• Summary — what the document says
• Insights — what matters in it
• Risks — where the problems are
• Recommendations — what to look at next

Deep Analysis adds further sections specific to the document type.

You can export a result as Markdown, or share it.

What happens to your document.

The PDF stays on your device. KeyLen AI extracts its text on your device, and sends that text — not the file — for analysis.

Analysis runs on our service, which passes the text to the AI provider that produces the result. The extracted text is not stored on our servers.

The result is stored so you can reopen it, and is deleted on a 90-day schedule. There is no account and no sign-in.

Free, and Pro.

The free tier gives you 3 quick analyses a day. Deep Analysis begins with the trial.

KeyLen AI Pro raises the allowance to 600 quick analyses and 300 deep analyses per month, and is available monthly or yearly. A 7-day free trial is offered.
