Bunni

Bunni is an AI document assistant that lets users upload a PDF and then summarize it, extract key information or ask questions answered from its content. Several files can be combined into one collection so that a question draws on all of them at once. Each document can be shared through a unique link, and the people who receive it can also ask questions. The product is aimed at researchers, students and professionals working through papers, reports and manuals. The vendor states that answers are based on the uploaded document rather than general internet knowledge, and that the service is suitable for non sensitive material only. Uploads of up to 20MB are supported on paid usage, and the site describes an API for uploads and questions, with API access charged only in credits. The homepage says the service runs on OpenAI models and that Claude and DeepSeek are planned. The vendor offers a free tier of 20 credits, valid for seven days, for documents up to 5MB. Paid usage is credit based. Credits cost from $0.015 each in packs starting at $10, and purchased packs are valid for one year. One credit covers each PDF upload and each standard quality question, while summaries and higher quality answers cost more. The site states there are no recurring fees and describes a full refund policy.
