Become a sponsor to Virgilio Junior
Open tools that keep your data on your machine 🔒
I'm Virgílio, an SRE and indie builder from Boa Vista, Roraima, Brazil. I make open-source tools around one belief: powerful workflows should not cost you your privacy or your context window. Everything I ship is local-first, dependency-light, and MIT.
The ecosystem
| Project | What it does |
|---|---|
| 📚 book-to-skill | Turns books and documents into structured agent skills for Claude Code, Copilot CLI, and Amp. It distills frameworks and decision rules into a compact skill the agent loads on demand, instead of dumping whole books into context. Thousands of stars, a multilingual contributor community. |
| 📄 localpdf.io | Every PDF tool you need, 100% local and 100% private. Convert PDF to Word/Excel/images/text, OCR scanned docs, merge, split, and compress, all self-hosted with Docker. No accounts, no cloud, nothing leaves your computer. |
Why sponsor
I maintain both on my own time: reviewing PRs, fixing edge cases across languages, shipping releases, and writing docs. Sponsoring funds that time and keeps these tools free, open, and private for everyone.
Every sponsor is a star in the constellation that keeps these projects alive. Whether you use them daily or just believe in privacy-first open tooling, thank you for being here. ✨
