Document chat that reads your PDFs and cites the page
Beginner
What is DocGPT.io?
DocGPT.io is an academic research tool. DocGPT is a web app that reads the PDFs you upload and answers questions about them, citing the page where the answer appears. It also offers GPT-4 chat, multi-document conversations, arXiv and Wikipedia lookups, and unlimited document storage.
DocGPT is a browser based workspace that pairs a PDF editor with a GPT-4 chat layer. You upload a document (books, research papers, manuals, essays, contracts are the examples the product itself names) and then ask questions in plain language. The tool reads the file first, so answers draw on the actual contents rather than a generic model response. Where relevant it points back to the page where the passage sits, and it can also add outside knowledge on top of what the document says. The product goes beyond single-file Q&A. Several documents can be discussed in the same conversation, which suits anyone comparing contracts, cross-referencing papers or working through a reading list. A plugin layer lets the assistant reach external sources such as Wikipedia and arXiv, so a session can start from your own files and pull in outside material when the uploaded material is not enough. The site frames a typical flow around drafting a scientific paper from documents in your cloud, with the assistant sent to search arXiv or Wikipedia for supporting information. The audience is fairly broad by design: students working through textbooks and assignments, researchers, and professionals who deal daily with dense paperwork such as contracts. The homepage also presents the chat side as a cheaper route to GPT-4 level models, and a prompt wizard is included in the plan. Among document-chat tools, DocGPT leans on the combination of editor and assistant rather than retrieval alone. It competes on price and on breadth (chat, storage, tools, external lookups) instead of deep enterprise features; the small independent team and the limited public documentation are the trade-off to weigh against better-supported rivals.

Pros and cons
Pros
- Answers questions directly from the uploaded file and points to the page where the information sitsAI
- Handles several documents in one conversation, which helps with comparisons and cross-referencingAI
- Built-in access to external sources such as arXiv and Wikipedia for filling gaps in the uploaded materialAI
- Unlimited document storage is bundled into the paid plan rather than sold as an add-onAI
- Rotating early bird pricing of 30 days free, then $4.99 per month, undercuts typical ChatGPT premium costsAI
Cons
- The public site is thin on detail about file formats, size limits and how the cloud storage is securedAI
- No pricing page beyond the single early bird offer, so renewal terms and future price changes are unclearAI
- External lookups cover only a short list of sources (Wikipedia, arXiv mentioned), not broad web searchAI
- The plugin set is described as coming in the future, so some of the promised research tooling is not yet liveAI
- Little visible documentation, help centre or API for teams that need to audit or integrate the toolAI
