On semantic retrieval
Keyword search finds tokens. Embedding search finds meaning. We want both.

Slept poorly. Decided the search palette should accept DSL fragments, not just text.

Three notes I want to revisit before the week ends. Filed under 'research'.

Reading: A Pattern Language
Alexander's patterns map cleanly onto component design. Especially #159, light on two sides.

Note as the unit of thought
Documents are containers. Notes are atoms. Atomic notes make recombination cheap.

Knowledge as a graph
Notes are not documents.
They are nodes.
The unit of thought is the note.

Search the words.
Find the meaning.
Sugilite runs hybrid search by default — exact keyword matching and on-device semantic retrieval, fused into one ranking. So a literal term lands every hit, while a question in plain words still surfaces the notes you meant, even when they share no keyword at all.
Every note is embedded right on your machine by a built-in EmbeddingGemma model. No API keys, no account, nothing sent to the cloud.
Your vault,
ready for any AI.
Sugilite ships with a standalone Model Context Protocol server. No GUI required. Launch the binary, point any MCP-compatible client at it, and your notes become tools — search, read, write, embed, traverse the graph.

Works with Claude, Gemini, ChatGPT, Cursor, Windsurf, Antigravity, and any other client that speaks MCP. Use the app for writing, or skip it entirely — your AI sees the same vault either way.
Bring your vault. Keep your habits.
If you already use Obsidian, Sugilite reads your vault directly. No conversion, no export. The shortcuts that already live in your hands keep working.
