About Bunni
Bunni is an AI tool that enables users to chat with PDF documents, asking questions and extracting information from uploaded files. The platform supports large files up to 20MB and allows users to upload multiple PDFs simultaneously, querying them as a unified collection. Users can share documents and Q&A sessions with others via unique links and choose whether to allow shared access to ask additional questions. The tool is designed for researchers, professionals, and students who need to quickly summarize academic papers, extract data from reports, or reference technical documentation. Bunni operates on a pay-as-you-go credit system with no recurring fees, making it accessible for occasional users. The platform currently uses OpenAI's GPT-4, GPT-4o mini, o2, and o2 mini models, with plans to add Claude and DeepSeek support. A notable limitation is that Bunni is recommended only for non-sensitive content, as users are advised not to upload private or sensitive material.
