What it does

aiPDF lets you upload a document and ask questions about it, summarise it or extract information from it. The site says it accepts PDFs, EPUB books, website URLs and YouTube links. Answers are drawn only from the uploaded material and come with references to the passages they rely on. You can begin chatting while summaries are still being generated, the tool replies in the language of your question, and responses can be exported. Stored documents can be deleted manually at any time. Automatic deletion happens after one month on the Playful tier and six months on the Dynamic tier, while Flagship documents are kept until you delete them. The site says data sent to the AI is excluded from external model training. It runs in a web browser with nothing to install, and file-size limits depend on the plan.
