Auto Tagger (Jev)

An Obsidian plugin that suggests or applies a tag to the currently open note using TypeSafe's Jev model and the tags that already exist in your vault.

Install it from the Obsidian community store.

How it works

1. Run Auto-tag current note from the command palette, or click the tag ribbon icon.
2. The plugin reads the note title and the start of its body, and collects your most-used vault tags.
3. It asks Jev a single Choice question: which tag best matches this note. The candidate list includes a literal None of these fit well option.
4. The chosen tag is applied (unless "None of these fit well" won), and a notification shows the tag and the model's confidence so you can build an intuition for your own vault before trusting any threshold.

Applying tags

• If the note already has frontmatter, the tag is added to its tags list.
• Otherwise an inline #tag is appended to the end of the note.
• Tags the note already has are never duplicated.

Settings

• TypeSafe API key — required. Stored locally in your vault, never logged.
• Tags to consider — how many of your most-used tags to send (1 to 25, default 15). Sending fewer, higher-signal options improves the model's discrimination.
• Note body characters — how much of the note to send, taken from the start (default 2000).
• Dry run — show the suggested tag without changing the note.
• Developer mode — log the raw Jev response (tag, confidence, and full probability distribution) to the developer console.

Privacy

• When you run Auto-tag current note, the plugin sends the note title, the first Note body characters of the note, and the candidate tag names to TypeSafe (https://api.typesafe.ai/v1/systemone) using the Jev model. No other vault content is read or transmitted.
• This happens only when you explicitly trigger the command or ribbon icon. The plugin makes no automatic or background network calls.
• Your TypeSafe API key is stored locally in the vault's plugin data file and is used only as the bearer credential for that request. It is never logged.
• The plugin collects no telemetry and sends no data to any service other than TypeSafe.
