New in v1.1.0: Launch into Obsidian community and ready for installation.

A vault that connects itself,
one note at a time.

SANE quietly reads your notes, finds what belongs together, and weaves the threads — tags, summaries, links — without ever touching your prose.

Install for Obsidian See how it works

— What it does

A quiet librarian for the notes you've already written.

Six small powers that, together, turn a folder of notes into something that remembers itself.

Semantic similarity

Notes are compared by meaning using embeddings. "Neural networks" finds your jottings on "backpropagation" — even when no word matches.

Lives in frontmatter

Tags, keywords, links, summaries — all written to the YAML at the top. Your prose stays exactly as you wrote it.

Triggers, your way

Process instantly on save, after a delay, on a schedule, or strictly on demand.

Five providers

OpenAI, Google AI, Grok, Azure, or fully local with Ollama. Mix and match for embeddings and chat.

Cost-capped

Daily budget limits and real-time tracking. No runaway bills, no surprises.

Always reversible

Every added field is prefixed sane_. One command undoes everything.

— The process

Four steps, repeated quietly, every time you write.

You write

Add or edit a note. SANE notices and waits — or fires immediately. Your call.

It listens

An embedding is computed for your new content and compared against the vault's semantic map.

It finds kin

The most relevant existing notes surface as context — the threads worth weaving.

It enriches

Tags, keywords, links, and a summary land in the frontmatter. The body of your note stays untouched.

— What it leaves behind

A handful of quiet annotations.

Everything SANE adds lives in the YAML frontmatter, prefixed with sane_. Delete the prefix, and every trace is gone.
