Save PDFs to one library and ask questions across them

Share a PDF into Kajr from Files, Mail or any app with a share sheet, and it is saved to your library on your device. Kajr summarizes it, tags it, and lets you ask questions across all your PDFs and saved links at once, with each answer citing the save it used.

PDFs are where knowledge goes to hide

Papers, contracts, manuals, statements and reports end up in a downloads folder with names like “final_v3.pdf”. Nobody reopens them to find one clause. A summary and tags on arrival make them findable, and questions make them useful.

Ask about one document or all of them

Ask “what is the notice period in my lease?” or “which of my saved papers use a randomized controlled trial?” and Kajr answers from your saves and shows which PDF each answer came from. Always check the original for anything with legal or financial consequences.

Think before you ask about sensitive documents

PDFs stay in your library on your device. When you ask a question, the relevant text is sent to a cloud AI provider to generate the answer, so keep that in mind before asking about anything confidential.

Questions you can ask Kajr

When does my lease end and what is the notice period?
Which of my saved papers use a randomized controlled trial?
What does the warranty in the washing machine manual cover?

Frequently asked questions

Are my PDFs uploaded to the cloud?

Your PDFs are kept in your library on your device, and Kajr does not maintain a cloud copy of them. When you ask a question, the relevant text is sent to a cloud AI provider to generate the answer.

Can I ask questions across several PDFs at once?

Yes. Ask about a topic and Kajr pulls from every save that touches it, PDFs and links together, and shows which ones the answer came from.

Can I rely on the answers for legal or financial documents?

Use them to find the right passage, then read the original. Summaries and answers can miss detail.
