Turn any document into clean, AI-ready Markdown,
right on your machine.
PDF, Word, Excel, images, scans, web pages, even YouTube links: Sygal converts them locally into clean Markdown and structured JSON, ready to drop into a prompt, a knowledge base or a pipeline. On scans, images and web pages in particular, that also means far fewer tokens for your AI.

Reads everything you throw at it
From raw to
clean Markdown.
Drop a dense PDF, a spreadsheet or a screenshot. Sygal returns clean Markdown you can read, or JSON your pipeline can parse.
A raw file and clean Markdown aren't the same to an AI.
Sygal normalizes every document into one clean, structured output your AI can actually work with. What that changes depends on where the file comes from.
2 to 7x lighter, where it counts
Images, scans, PDFs, web & YouTubeA scan, a screenshot, a scanned PDF or a web page carries a lot your AI pays to read but never uses: pixels, layout, markup. Converted to text, the same content can run roughly 2 to 7x lighter on tokens, and the model reads what matters. YouTube links come in as clean transcripts, ready to summarize or search.
The gain is largest on visual and web content; exact figures vary with each file.
One clean, consistent output
Word, Excel, PowerPointAlready-structured files get a different win: Sygal standardizes them into the same clean Markdown and JSON as everything else. One predictable output for your whole pipeline, ready to parse, search and reuse, with no format-by-format handling.
Whatever a document starts as, it ends the same way: clean, structured, and ready for your AI.

NVIDIA NIM and Gemini are also available, along with a custom provider. NVIDIA offers a free option to get started with no API budget.

Your documents stay on your machine.
Two columns, no ambiguity: what stays, what can leave.
Stays on your machine

Questions, answered.
Everything you might want to know before you try Sygal.
Yes. Documents are converted locally with MarkItDown, so they never leave your machine and there's no account to create. Only images you send through OCR, and URLs you choose to import, reach the network. You choose from built-in providers (OpenAI, Claude, Mistral, NVIDIA NIM) or add any custom provider with your own API key.
“I'm an independent developer in Paris. I built Sygal for two reasons: to stop using tools that upload everything, lock you into a subscription, and still hand back messy text; and to stop burning through my AI credits. A raw document drags along a lot of noise an AI has to read without needing it. Sygal is the tool I wanted for myself: local, paid once, built to hand my AIs clean text. If it spares you the same hassle, that's the whole point.”
