Mixed PDF and EPUB sources
Ready sources in both formats can provide evidence, with real chapter locations for EPUBs.
AI Knowledge Base Q&A
Collect research PDFs and EPUBs in a folder and ask AI to compare ideas, summarize evidence or help with writing. Retrieval uses relevant snippets from ready sources, with real page and chapter citations you can inspect.

Upload PDFs and EPUBs into a folder and wait for parsing and indexing to finish.
Open AI chat at the bottom of the folder, ask a comparison, summary or writing question, and confirm the request cost.
Open page or chapter citations, check the original, and continue asking or organizing your own notes.
Ready sources in both formats can provide evidence, with real chapter locations for EPUBs.
All authorized, valid sources in the folder are retrieval candidates, regardless of list filters or pagination.
Answers use relevant snippets and cite source titles with PDF pages or EPUB chapters.
Ask follow-up questions in the current page session. Successful answers use the configured request price.
Ask where papers agree or differ and inspect the evidence behind each position.
Develop an argument from folder sources, verify citations, and write your own account.
Collect tutorials and books and ask about concepts to guide further reading.
All valid folder sources are candidates, but each answer uses a bounded set of relevant snippets. It does not claim to read or cite every book in full. Pending sources are not treated as read.
Yes. Parsed and indexed PDFs and EPUBs participate in retrieval. Citations show pages for PDFs and chapters for EPUBs.
Membership and AI credits are separate. Each successful answer uses the configured request price, shown before starting. Failed requests release reservations; replaying the same request does not charge twice.
Follow-ups are supported in the current page session. Folder contexts stay separate. History recovery after refresh is not promised.
Your documents, canvas and maps belong in one workflow.
