For Zotero
Books, turned into Markdown.
Right-click any item in your Zotero library, nominate a page range, and receive a structured Markdown transcription attached to the item — ready for Obsidian, Zettlr, or Claude.
Open source · pay as you go · your PDF is deleted asap
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.
Private by design
Pay as you go, and your PDF is deleted as soon as conversion completes. No training on your content. Open source if you want to verify — and there's a fully local mode if you'd rather we never saw it at all.
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.
