Think
in links.
Tessera is a note-taking system that stores what you know the way you actually know it — as a network, not a filing cabinet.
Notes are cheap to write and expensive to find. Tessera inverts the cost: bidirectional links, on-device semantic search and daily resurfacing make retrieval the default outcome of writing anything down.
A single note and its neighbourhood. Solid lines are explicit links; dashed lines are unlinked mentions Tessera has detected.
Capture is cheap. Retrieval is everything.
Any tool can store a note. Almost none can give it back to you at the moment you need it. Tessera is designed backwards from retrieval: every feature exists to make old thinking findable.
Links, not folders.
A folder holds a note in one place. A link holds it in many. Type two brackets and the structure builds itself — bidirectionally, automatically, permanently.
Meaning over keywords.
You rarely remember the words you used. You remember what you meant. Search runs on device against meaning, in under forty milliseconds.
Plain text is the only format that lasts.
Your vault is a folder of Markdown files. Open it in any editor. Back it up with anything. Leave whenever you like — you won't need to.
Privacy is a feature, not a setting.
Sync is end-to-end encrypted. Indexes are built on your machine. There is no version of Tessera that can read your notes.
