Your second brain should run at the speed of thought.Not the speed of a bloated browser window.

Modern note applications devour 2GB of RAM just to render a bulleted list, introduce 80ms typing latency, and hide your knowledge inside proprietary SQLite blobs. Syntact treats your thoughts as a high-throughput plaintext filesystem kernel: instant sub-millisecond fuzzy indexing, bidirectional AST backlinks, and pure keyboard flow.
