Yes — eight apps let you upload a book PDF and ask it anything, and Otio and ChatPDF fit that use best

Asked:

“apps like notebook lm but for like say if i am reading a book and then i can upload the pdf and then get summary, or a query or anything”

This shortlist compares eight upload-and-chat apps — ChatPDF, Otio, AskYourPDF, SciSpace, Adobe Acrobat, Claude, PDFgear and Sharly AI — on summaries and Q&A, citation support, document types, free option, stated paid price and stated limits. Every claim quotes one first-party page per app (eight independent official hosts), researched on 2026-09-21.

Upload only legally obtained, non-DRM PDFs, and verify important answers against the cited pages — pricing and limits change, and ambiguous extracted figures are flagged below rather than smoothed over.

Method: comparison shortlist of 8 AI PDF-chat apps, one row per app, built from first-party pages only (8 independent hosts; no URL backs more than 1 of 8 rows, 12.5%), researched 2026-09-21. “Official pages found” counts pages matched in this scan, not quality. Null fields shown as “not confirmed”; ambiguous extracted prices or limits (e.g. Sharly AI’s “10”, Otio’s unstated billing period) are flagged, not interpreted. Long quotes trimmed for space in cards; the table keeps full source language.
