Question 1

Is PDF Chat free?

Accepted Answer

Yes — sign in with a free KaamSet account to upload PDFs and chat with them. Daily upload limits keep costs sustainable; premium accounts get higher caps.

Question 2

How large a PDF can I upload?

Accepted Answer

Up to 20 MB. For very large documents, split into logical sections (e.g. chapters) for the fastest retrieval.

Question 3

Does it work on scanned PDFs?

Accepted Answer

Only if the PDF contains real text. Pure-image scans need OCR first — try the Notes Beautifier's OCR step or run any OCR tool, then paste the text into the AI Notes Summarizer.

Question 4

Are my PDFs private?

Accepted Answer

Yes. Each PDF is stored under your account with row-level security so only you can query it. We never share documents.

Question 5

How accurate are the answers?

Accepted Answer

PDF Chat retrieves the most relevant passages and sends them to the model. Answers are grounded in your source. If something is unclear, click the citation to read the original passage.

Question 6

Can I delete a PDF later?

Accepted Answer

Yes — use the 'New PDF' button on the tool screen. Future versions will let you manage your full library.

Question 7

Why is the first question slow?

Accepted Answer

Indexing a long PDF can take 10–30 seconds depending on length. Subsequent questions are fast because the embeddings are cached.

Question 8

Can I share an answer with classmates?

Accepted Answer

Use the Publish to Library button to share notes generated from the conversation as a public study page.
