Why Estravon.
One job, done properly.
Markdown, attached in place
A first-class Zotero attachment — synced, versioned, and always sitting next to the source it came from.
Built for books
Chunking, section naming, tables of contents, and scanned pages — the hardest cases handled, not avoided.
Flows into your tools
Open the output in Obsidian, Zettlr, or Claude. It's just Markdown — no lock-in, no special format.
Your key, your control
Open source, pay as you go, and your PDF is deleted within the hour. No training on your content.
How it works.
Right-click an item
Pick any book or chapter in your Zotero library that has a PDF.
Choose a page range
Name the section, set the pages, and pick a quality mode. Hit go.
Get Markdown attached
A structured .md file lands on the item, with an extraction log for traceability.
Two ways in.
Same destination — a clean Markdown library. You just choose who flies the ship.
