Aginsi vs ChatPDF

Aginsi is an AI research co-pilot that turns reading material into summaries with key passages highlighted. It accepts articles, academic papers, PDFs, long threads, reports, and video transcripts; summaries keep their references and show the amount of compression and estimated reading time saved. The free Margin plan costs nothing and includes 10 monthly summaries for articles and PDFs. Scholar costs $9 a month and adds unlimited summaries, a library with tags and search, Markdown and PDF export, and a browser companion. Faculty costs $29 a month and adds team seats, shared shelves, batch and API access, and priority support. The product is available through web, extension, and API. Aginsi says it discards submitted source documents and retains only summaries users choose to save. Source text is processed transiently and not used to train models. Users can request access to, correction of, export of, or deletion of account data and saved summaries by contacting [email protected]. The company describes itself as a small studio in Helsinki.

ChatPDF lets users summarize documents and ask questions about their contents using conversational AI. Answers include citations that point to references in a PDF, and users can organize files in folders or discuss multiple PDFs in one conversation. It accepts PDFs in any language and supports conversations in any language; listed file types also include Word, PowerPoint, Markdown and text. Sharing links can be created, with access permissions managed or revoked. ChatPDF says documents are encrypted during transfer and storage and can be deleted by the user. Queries are routed dynamically between GPT-4o and GPT-4o-mini. The service works in a browser on any device and is listed for Android, iOS, Linux, macOS and Windows. Its backend API accepts uploaded PDFs or public URLs and lets users query them to build custom PDF chatbots. The API documentation limits each PDF to 2,000 pages or 32 MB and describes the chat API as stateless. The Free plan costs nothing and allows two documents per day.
