Why I Built Knovum: A Local-First Infinite Canvas AI Workspace

说明与用途

Knovum 是一个本地优先的知识工作空间，具有无限画布和嵌入式 AI，提供隐私保护和即时语义搜索。

问题

Existing productivity tools force users into rigid tree directories or lock private thoughts behind proprietary cloud subscriptions.

结果

Knovum delivers a lightweight, secure, and privacy‑preserving knowledge workspace with infinite canvas, local AI, and semantic search, outperforming traditional tree‑based tools.

工作流

• 1. Choose Tauri 2 as the desktop foundation for low memory footprint and security.
• 2. Build the infinite canvas with Vue 3 and Konva, enabling 60 fps and JSON Canvas compatibility.
• 3. Store data locally in SQLite and index vectors with LanceDB for instant semantic search.
• 4. Transcribe audio locally using Whisper + FFmpeg and slice into time‑coded note cards.
• 5. Integrate Model Context Protocol for bi‑directional AI agent workflows.
