MDFlux v0.1.0

Turn any document into clean, AI-ready Markdown. Runs on your machine, nothing uploaded, and it reads the scanned PDFs other tools miss.

This is the first public build of MDFlux, a portable Windows app built on Microsoft's MarkItDown.

What it does

• Converts PDF, DOCX, PPTX, XLSX, EPUB, HTML, CSV, JSON, XML, images, and audio into clean Markdown.
• Reads scanned, image-only PDFs with built-in OCR (plain text extractors return zero characters on these).
• Uses up to 6 times fewer tokens than feeding pages to a vision model, so every downstream LLM call costs less.
• Runs fully offline after a one-time first-run setup. No API key, no account, nothing uploaded.
• Batch-converts a whole folder with progress, cancellation, and per-file diagnostics.
• Optional cleanup: off, rule-based, or a local AI pass.

Install

1. Download MDFlux_0.1.0_portable.zip below.
2. Extract it anywhere (for example C:\Apps\MDFlux\).
3. Run MDFlux.exe.

This is a portable app, so there is no installer. The first launch sets up a private, self-contained Python environment (one time, needs internet). After that it runs offline.

Notes for the first run

• Windows SmartScreen may show a one-time "Windows protected your PC" message. The build is open source and unsigned, so click "More info" then "Run anyway". Code signing is on the roadmap.
