MDFlux

MDFlux is a desktop app for turning documents into structured Markdown for AI workflows, research, or text editing. It suits people who need usable text from mixed files and scanned archives while keeping conversion on their own machine.

• Document conversion: Convert PDFs, Word documents, PowerPoint slides, Excel spreadsheets, EPUB books, HTML, and data files while retaining headings, tables, and lists.
• OCR and transcription: Extract text from scanned PDFs and images, including images embedded in documents, and transcribe audio locally.
• Folder batches: Process a folder of mixed files with per-file progress, cancellation, and diagnostics, then inspect the Markdown in a rendered preview.
• Optional cleanup: Keep the original extraction, apply rule-based fixes, or use a local model through Ollama; a Changes tab shows additions and removals line by line.

The app builds on Microsoft's MarkItDown and is free, open source, and MIT-licensed. It runs on Windows and Linux x64 without an account. Lite needs internet on first launch; Full bundles the document-conversion and OCR runtime for offline setup. Both editions download speech model weights on demand, while subsequent document conversions run offline.

Local conversion and Ollama cleanup keep documents on your machine. An optional API cleanup mode sends text to an external provider such as OpenAI, DeepSeek, or another OpenAI-compatible endpoint and requires your own API key. MDFlux doesn't manage Ollama model downloads.
