pdf2gpt

Main features: PDF summarization and asking specific questions about a PDF. Core characteristics:

1. Huge PDFs supported: Automatically breaks PDFs into chunks so it fits into the GPT context limit.
2. Fast: Upload files right away, no account needed for smaller files.
3. Powered by GPT: Rides the GPT hype train with underlying GPT model capabilities. Usage flow: Users can choose to 'summarize' or 'ask a specific question about' a PDF. Files can be uploaded via drag-and-drop or by pasting a URL. After submission, the system processes the file and outputs a summary or answer, with an option to ask further questions about the generated summary. Pricing model: Freemium and paid. Smaller files can be processed for free without an account; however, the developer noted they cannot keep the service completely free due to piling up OpenAI bills, implying paid requirements for larger files or heavier usage (specific prices not listed).
