What is Bunni?
Bunni is an AI tool for chatting with PDF documents. It lets you upload one or more PDFs, ask questions about their contents, and get summaries or extracted information from the files themselves rather than from the public web.
The product is built around a simple chat interface for documents. You can use it to summarize research papers, annual reports, news articles, instruction manuals, guides, and how-tos, which makes it useful for quickly finding facts hidden inside long documents.
A key feature is support for large files up to 20MB, along with multi-file chat that treats several PDFs as one combined knowledge source. Bunni also offers shareable document links so you can share the PDF and the Q&A thread with others, and optionally allow them to ask questions too.
Bunni is positioned as a pay-as-you-go service with no recurring fees. It supports all languages and uses OpenAI models including GPT-4, GPT-4o mini, o2, and o2 mini, with Claude and DeepSeek listed as coming soon.
It is aimed at students, researchers, professionals, and anyone who needs to extract answers from documents quickly. The website also says it is suitable for non-sensitive content and should not be used for private or sensitive material.
