#sqlite

Substrate runs as a personal web application. You sign up, get your own space, and start writing. No social feeds, no algorithms, no noise.

Under the hood, Substrate uses SQLite for storage, full-text search for finding things fast, and semantic embeddings for discovering related ideas you might have forgotten about.

Substrate is built on the principle that your notes are yours. Not stored on someone else's cloud, not mined for training data, not locked into a proprietary format.

Storage

Everything lives in a single SQLite database file. It is fast, portable, and backed by decades of reliable technology. You can back it up, copy it, or move it anywhere.
