aiPDF is a web app that lets users summarize, extract information from and chat with documents. The homepage describes it as an AI tool for any file, and the product accepts PDFs, EPUB books, website URLs and YouTube videos.
It is operated by Ethical Network, a company registered in London. The founding team of Cata, Rishi and Theo met online in early 2023. The company says it donates monthly to environmental charities through earth.fm.
A user uploads a file or pastes a URL. The company says documents go through a brief preprocessing period that depends on their size, after which the AI generates summaries. Chatting can begin while summaries are still being produced.
When a question is asked, the system matches it with the relevant sections of the document and answers from the information found there. The site says responses are double-checked and come with references extracted from the uploaded files.
The core feature is question answering over a document, with summaries of anything up to full books. Multi Document Chats and Joins let users work across several files, and OCR pages cover scanned material. Responses can be exported for reports or research notes.
The company also lists language support: it says the system handles all languages and replies in the language of the query. On the control side, users can delete documents manually whenever they choose.
