Sygal is a document converter and Markdown tool for macOS and Windows. It helps you turn documents, PDFs, scanned files, URLs, YouTube links, and copied text into clean Markdown or JSON. The output is structured, easy to reuse, and ready for AI workflows, note-taking, search, or automation.
Sygal runs 100% locally on your machine, without cloud processing. That means your files stay with you, which is especially useful when you work with sensitive, private, or confidential documents.
It is built for developers, researchers, writers, consultants, and anyone who wants a fast way to prepare documents for AI without giving up control over their data.

Sygal converts documents into Markdown and JSON entirely on your own machine, with no cloud processing and no account required. Files never leave your device, which matters when you work with scans, images, or confidential documents. Beyond files, it also converts web pages and YouTube videos, and can translate the Markdown output into English, French, Italian, Spanish, or German using AI.
Developers and technical users who feed documents into AI/LLM pipelines, plus professionals who handle confidential documents daily: consultants, accountants, legal and executive assistants, researchers, and writers who need a fast, private way to turn PDFs, scans, or web pages into clean text.
Sygal was built by an independent developer in Paris who needed a reliable way to turn his own documents into AI-ready Markdown without uploading them to a cloud service. It grew from a personal tool into a packaged macOS/Windows app, then into a CLI for developers and AI agents, keeping the same local-first principle throughout.
Most document-to-Markdown tools, PDF editors like Adobe Acrobat, or online converters like Zamzar process files through a server you don't control. Sygal runs the conversion locally, so nothing is uploaded unless you explicitly opt in to OCR with your own API key. It's a one-time purchase (no subscription), runs on macOS and Windows (plus Linux via the CLI), and outputs clean Markdown and JSON ready to feed into AI pipelines.
The desktop app is built with Electron, and the Sygal CLI is a Node.js package published on npm. Document parsing builds on the open-source MarkItDown library, extended with local logic for structured Markdown/JSON output and optional OCR.
