Sygal

Sygal converts PDF, Word, Excel, images and web pages into clean Markdown and JSON locally.

Sygal is a document conversion tool designed to turn raw files into clean Markdown and structured JSON for artificial intelligence pipelines. It processes documents locally on Mac and Windows machines to protect user privacy. Users can drop PDFs, Word documents, Excel spreadsheets, images, web pages, or YouTube links into the application. The software automatically detects formats and normalizes them into consistent outputs, which reduces token usage for artificial intelligence models. For scans and images, users provide their own API keys to utilize optical character recognition providers such as OpenAI, Claude, Mistral, NVIDIA, or Gemini. The application also includes a persistent local library with full-text search, native preview windows, editable results, batch conversion, and a command line interface.
