zapp2md: Export WhatsApp Chats to Markdown for LLMs with Voice Message Transcription

⚡ The gist in 5 seconds - The utility zapp2md exports WhatsApp chats into a single Markdown file for Claude, ChatGPT, Gemini, and other LLMs. - Voice messages are transcribed, and text from images and PDFs is extracted automatically. - Works fully locally, free of charge, Windows only. IT/PT/EN languages are supported. ### 🔍 What was found The amotvvv/zapp2md project has been published on GitHub — a tool for converting exported WhatsApp chats into a single Markdown document optimized for feeding into large language models. According to the README, the utility transcribes voice messages, recognizes text in images and PDF files, and then assembles everything into a structured document. It is Windows-only, free, and processes data locally — nothing is sent to the cloud. How it works: the user takes a standard WhatsApp chat export (usually a.txt or.html file), runs zapp2md, and the utility converts it into a single.md file. Built-in transcription and OCR modules process media attachments, embedding the results directly into the text. Three interface languages are listed in the description — Italian, Portuguese, and English. ### 💡 Why it matters zapp2md solves a common data-preparation task for LLMs: instead of manually processing dozens of files, the user gets one clean Markdown document that includes texts, voice message transcripts, and the contents of images/PDFs. This simplifies analyzing conversations, building datasets, and creating personal AI assistants. The tool is fully local, which matters for privacy, but it is limited to Windows and a small set of languages. The project is still fresh, so stability and format support should be verified on a case-by-case basis.
