Caspian is a local-first knowledge base that lets you anchor plain Markdown notes to any image, map, 3D model, or webpage, storing your notes on your disk rather than relying on external cloud storage.
Key benefits include:
- Local Vault Ownership: Notes are stored as plain Markdown files in a personal directory (vault) on your disk, with full control and no account or cloud dependency.
- Versatile Anchoring: Import images, maps, 3D models, or webpages and pin/draw regions to attach notes directly to specific areas of the content (e.g., anatomy diagrams, geographic locations, floor plans).
- Visual Navigation: Navigate notes by clicking anchor points on visuals instead of searching through folders or graph views, simplifying access to related information.
- Unified 2D/3D Support: A single anchoring system works seamlessly for flat floor plans, rotating 3D models, and other media types, ensuring consistent note organization across formats.
Perfect for students, researchers, educators, or anyone needing spatial note organization with local data control.
