aiPDF

aiPDF is a web app for chatting with documents. Users upload a PDF or EPUB, or paste a link to a web article or YouTube video, and then ask questions, request summaries and extract information from the content. The vendor says answers are backed by references to the passages in the uploaded material and that the assistant responds in the language of the question. It is aimed at students, researchers and professionals who work with long reports, essays, ebooks and other dense material. Summaries are generated while the document is still being processed, so a conversation can begin before they finish. The paid plans add multi document chats and joins, which combine several files in one conversation, and optical character recognition pages for scanned files. The vendor also says users can delete their documents manually and that it donates monthly to environmental charities through its own charity, earth.fm. Pricing is published in three tiers, with a yearly billing option that the page says saves up to 30 percent. Playful Free allows 2 PDF uploads, 550 questions, a 35 MB maximum file size and 50 OCR pages. Dynamic costs $9 per month and allows 120 uploads, 5,500 questions, a 50 MB maximum file size, 5 multi document chats and 500 OCR pages. Flagship costs $19 per month with unlimited uploads, storage duration and questions, a 65 MB maximum file size, unlimited multi document chats and 3,000 OCR pages. An Enterprise package with commercial use is available through a contact form.
