A developer shares their journey building Outcrop, a knowledge base alternative to Notion, using Rust for performance and simplicity. The project includes custom implementations of a Zanzibar-inspired authorization system, a search engine using tantivy with sub-millisecond latency, and a Rust port of ProseMirror for real-time collaborative editing. The architecture prioritizes speed through in-memory authorization checks, integrated search with permissions, and microsecond-level document processing. The product targets software teams and aims to launch within six months at €10 per seat.

<p>Note-taking is dead. If you really want Obsidian, is the best. With memory getting better, chatbots can replace note-taking tools quite easily in the future. If you want to find gaps in your thinking, knowledge base LLMs are the best alternatives to manually linking ideas. PS. You need research skills to efficiently adopt AI. Note-taking is mostly documenting human hallucinations. That was the pitch that starts the hype-cycle madness we are in, all of which have failed to display significant results - notetaking, work-from-home, blockchain, generative-ai, and subscription social media (dail.dev is a child of this hype).</p>
