What our research says

AskYourPDF

A sensible pick when the job is repeatable question-answering across a document library rather than one clever answer, and the embeddable agent plus API are what separate it from the many ChatPDF clones. If you already live in Google's stack, NotebookLM covers the research half at no cost.

Pros

Page-level source citations instead of unattributed summaries
Documented API and Chrome extension, so it fits into existing workflows
Very large per-document page ceilings (2,500 on Premium, 6,000 on Pro)
Premium at $11.99/month billed yearly undercuts most document-chat rivals

Cons

Free tier is one document, three conversations and 50 questions per day
Advertised prices are annual-billing rates; monthly billing costs about 25% more
Daily rather than monthly quotas mean a heavy research day hits a hard wall
The 40-plus free writing tools are search-traffic surface, not the product

Knowbase

Stronger than the usual chat-with-PDF tool because audio and video are first-class: transcription with speaker labels means meeting recordings join the same searchable pool as the documents. The limits are storage and query counts, and they bite early - 500 queries a month is a fortnight of real use.

Pros

Transcribes audio and video with speaker identification, then makes it searchable alongside documents
Queries either a single file or the whole library in one go
Connectors for Google Drive, Notion and Dropbox rather than upload-only
Shareable links and an embeddable chatbot widget, plus a documented API

Cons

Query caps are low - 500 a month on the $19 tier - and count against everyone in a shared workspace
No company name, address or jurisdiction is published on the site or in the terms PDF
Storage on the entry tier is 2 GB, which a handful of video files will exhaust
