aiPDF
Chat-with-your-documents app that ingests PDFs, EPUBs, web pages and YouTube videos with cited answers.
In short
aiPDF allows users to upload documents, books, or video links to ask questions and get summaries with source citations. It is best for individuals seeking a simple, free-to-start interface for document analysis without developer setup.
Pick aiPDF if you want a friendly, free-to-start chat-with-documents app that also handles EPUBs and YouTube videos, not just PDFs.
Skip it if you need an API, on-prem deployment, transparent model choice, or enterprise-grade document governance.
aiPDF is a document-chat web app that lets you upload PDFs, EPUB books, paste website URLs, or drop in YouTube links and then ask questions, request summaries, and pull structured insights with citations back to the source. It positions itself as a friendlier alternative to the wave of ChatPDF clones, with preprocessing for faster turnaround and a Q&A pipeline the team benchmarks against Google and Stanford evaluation sets.
The target user is a student, researcher, or knowledge worker who wants a low-friction reader-plus-chat interface rather than a developer building RAG into their own product. Pricing follows the standard freemium ladder (free tier plus Playful, Dynamic and Flagship paid plans) with file size and storage retention scaling by tier. There is no public API, no self-hosting, and the underlying model is not disclosed, so it's strictly an end-user tool.
Multi-language support and response export are the more useful extras over the basic ChatPDF feature set, but the user base is small and the product is clearly an indie effort rather than an enterprise platform.
aiPDF is a competent entry in the crowded chat-with-PDF space, with the nice twist of accepting EPUBs and YouTube links alongside documents. It's an end-user app, not a platform, and the lack of a disclosed model or API ceilings how seriously a team can adopt it, but the free tier makes it a reasonable everyday reader.
