Wedelia Notes

Lets Wedelia, an AI companion app, search your Obsidian vault while she answers you.

You ask Wedelia something. If your notes might help, she asks this plugin, the plugin searches the vault on your computer, and only what matched is sent back.

What leaves your device

• A search sends up to 5 matching excerpts, each at most 400 characters, with the path of the note it came from.
• Opening a note sends that one note, capped at 40,000 characters. Wedelia can only open notes you share (see below), and asking for a note you don't share gets the same answer as asking for one that doesn't exist.
• Nothing else. The vault is not uploaded, not indexed on a server, and there is no copy of it anywhere else.

The honest caveat: whatever is sent travels with that one request, so the AI model provider handling the request sees it, the same as the rest of your message. "Not stored" is true. "Never leaves your machine" would not be.

It only works while Obsidian is open. When it is closed, Wedelia is told your notes are unreachable and says so rather than guessing.

Never searched or opened

• What Wedelia's own vault mirror writes into your vault: the top-level Memories/, Diary/, People/ and Itineraries/ folders, and Tasks.md and README.md at the vault root. Otherwise she would read her exported memories back as if you had written them.
• .obsidian/ and anything else whose path starts with a dot
• Any folder you list under Private folders

Requirements and disclosures

• Account: requires a Wedelia account. The connection password comes from the Wedelia app.
• Network use:
  • api.wed.chat exchanges your connection password for a short-lived ticket.
  • The Wedelia notes relay (hosted on Google Cloud, its address comes with the ticket) receives Wedelia's search requests; the plugin holds a request open to pick them up and posts back the results.
• No telemetry: the plugin sends nothing beyond the above. How Wedelia handles your data is described in its privacy policy.
• Closed-source service: this plugin is MIT-licensed. The Wedelia app, API and relay it connects to are not open source.
• The plugin never modifies your notes and never touches files outside your vault.

Install

From Obsidian: open Settings → Community plugins → Browse and search for "Wedelia Notes", or open its directory page and select Add to Obsidian.

Manually: download main.js and manifest.json from the latest release into <your vault>/.obsidian/plugins/wedelia-notes/, reload Obsidian, and enable Wedelia Notes under Community plugins.

Set up

1. In the Wedelia app, open Privacy & data → Connect Obsidian and copy the connection password.
2. In Obsidian, open Settings → Wedelia Notes and paste it.
3. Optionally list folders to keep private, one per line.
4. Turn on Let Wedelia search this vault. The status reads Ready once it has connected.

Large vaults

Search never reads the whole vault. Obsidian already holds every path, mtime and heading in memory, so names, headings, tags and aliases are matched for free, and only the notes that matched get opened. When nothing matches for free it falls back to reading the 400 most recently modified notes, and the whole thing stops at an 8-second budget regardless: the request it answers lives 18 seconds, and answering late is the one failure it cannot have.

Measured on a 49,802-note, 60.8 MB vault: reading everything took 17.1s. That was never going to fit.

The ceiling this buys: a term that appears only in the body of an old note, whose name and headings never mention it, is not found. A real index is the upgrade, not a bigger scan. This is the best place to help.

Development

npm install
npm test
npm run typecheck
npm run build
node test/bundle.smoke.cjs

• src/ has everything with a decision in it, tested without an Obsidian runtime.
• main.ts is the Obsidian adapter: list files, read a file, settings pane.
• test/fixtures/relay-envelopes.json holds envelopes produced by the Wedelia relay. The relay only accepts a result that matches exactly, so the tests check the plugin builds the same bytes.
• npm run package builds a zip with a ready-to-copy wedelia-notes/ folder.
• Releases are cut by pushing a tag equal to the manifest.json version. The release workflow builds, tests, attests and publishes main.js and manifest.json, so release assets are never built on a laptop.

npm run build also writes dist/package.json marking the bundle as CommonJS. Obsidian evaluates it that way regardless, but without it Node reads the .js extension as ESM and the smoke test cannot load the bundle. An ESM bundle would load in Obsidian as an empty module with no error at all, which looks exactly like a plugin that installed fine and does nothing.

Contributing

Issues and pull requests are welcome. The relay protocol is set by the Wedelia service, which is not in this repository, so a change to the envelope format can't be accepted here on its own.
