About Diffsurge MD

Diffsurge MD is a privacy-first browser extension that intercepts files (PDFs, Excel, DOCX, etc.) you drop into ChatGPT, Claude, Gemini, and DeepSeek, and instantly converts them into clean Markdown before they are uploaded. Why use Diffsurge MD? 1. Save Tokens & Money: A typical PDF can drop from ~30k tokens down to ~8k tokens when converted to Markdown. This leads to faster AI replies, lower API costs, and much better context recall. 2. 100% Local & Private: Unlike other tools, Diffsurge MD runs a Python engine (Pyodide + Microsoft MarkItDown) directly inside a WebAssembly worker in your browser. Your files never leave your device for conversion. 3. Seamless Integration: It works automatically. Just drag and drop or click to upload your files into your favorite AI chat interface, and Diffsurge MD handles the rest in the background. Features: - Completely free and open-source. - No telemetry, tracking, or data collection. - Supports a wide variety of formats out-of-the-box (PDF, DOCX, XLSX, images, etc). - Optional self-hosted cloud engine available for audio transcription or excessively large files. Take control of your data and ship less to your LLM today!
