Bunni

Bunni is a document-first conversational tool that lets users upload PDFs to summarize, extract information, and ask questions directly about the document content. Designed for researchers, students, professionals and teams, it supports multiple languages, handles large files (up to 20MB), and can combine multiple PDFs into a single chatable collection. Bunni uses large language models (OpenAI's GPT-4 family currently, with Claude and DeepSeek coming soon) to generate answers based on the uploaded documents rather than general web knowledge.

The product is aimed at users who need fast, factual access to the contents of reports, academic papers, manuals, and other PDFs. It provides shareable links so you can share a document and its Q&A with colleagues, and uses a credit-based pay-as-you-go model (no recurring subscription) with a free trial option and a 100% no-questions refund policy.
