Managing bookmarks as a developer can be a frustrating challenge. That’s why we created VsCodex — a powerful VSCode extension designed to make your workflow smarter and more organized.

It uses LLMs (Large Langage Models) to recommand bookmarks based on the current file you are editing.

Developing a VSCode extension comes with its own set of challenges, the most significant being the inability to run processes outside the extension itself. To overcome this, we’ve adopted cutting-edge and portable technologies for the backend of this project.

By following a local-first approach, we’ve integrated DuckDB , a high-performance portable database with SQL-like syntax, packed with advanced features for data analysis. Even more impressive, it supports vector databases, unlocking powerful search and AI capabilities.

Additionally, we’ve incorporated Transformers.js , enabling the execution of lightweight LLMs directly in-memory. This ensures that users can make model requests without incurring any external costs or relying on cloud infrastructure, providing privacy and efficiency.

This innovative stack ensures that our extension is fast, private, and highly portable — ideal for modern development workflows.
