We build open tools for researchers. Our first product is Estravon — PDF-to-Markdown extraction for Zotero: turn book chapters and papers into clean, structured Markdown attached directly to your Zotero library items.
- estravon-plugin — Zotero plugin: extract PDF sections to Markdown, attached directly to the item.
- estravon-backend — Self-hosted Python backend: bring your own OCR key, or run fully offline with MinerU.
- estravon-backend-alternatives — Community backend adapters (markitdown, MinerU remote, and more).
- estravon-backend-benchmarks — Apples-to-apples PDF-to-Markdown engine comparison.
If these tools save you time, you can support Tiberavon — by card or via GitHub Sponsors. It funds hosting, OCR costs, and development time.
