Sombra

Sombra is a Chrome extension that transforms how you capture and organize knowledge from the web. Instead of bookmarking links that may break or disappear, Sombra saves the actual content as clean markdown, creating a permanent, searchable knowledge base that's truly yours.

SMART CONTENT CAPTURE Automatically converts web pages to clean, readable markdown with extended metadata. Captures visible screenshots using Chrome's native APIs. Works on authenticated sites without server-side authentication. Preserves content structure while removing clutter. If you can see it, you can save it.

AI-NATIVE INTEGRATION Native MCP (Model Context Protocol) integration for Claude Desktop and other AI clients. Query your saved content directly through AI assistants providing intelligent content analysis and categorization. Search across all saved content.

COMPLETE DATA OWNERSHIP Automatic sync to your personal Dropbox account. Export all data in standard formats (markdown). No vendor lock-in - your data remains accessible even without Sombra. Rolling background sync ensures nothing is lost.

FLEXIBLE ORGANIZATION Create custom collections to group related content. Browse by website/host for domain-specific research. Tag system for cross-cutting themes. Project-based organization for focused research.

PRIVACY & SECURITY No third-party data sharing. User data completely isolated (users never see each other's saves). Minimal server footprint with strong privacy protections.

PRICING Free: 100 lifetime saves with all features unlocked Pro: $7/month or $70/year for 2000 saves annually
Supporter: $120/year for unlimited saves and screenshots

PERFECT FOR Researchers building knowledge repositories. Students collecting sources for projects. Professionals tracking industry insights. Writers gathering reference materials. Anyone who wants to own their digital knowledge.

Sombra bridges the gap between ephemeral web browsing and permanent knowledge building, giving you the tools to create a personal knowledge graph that grows with your interests and expertise.
