Annotex

Publish the note you're editing to your self-hosted Annotex server with one command. Invited colleagues open the link, read the rendered note, and leave inline, anchored comments (with LaTeX). The note's Markdown — including $math$ — is rendered on the server and gets the Annotex comment layer + KaTeX.

This plugin needs an Annotex server — it's a companion to one you run yourself, and does nothing until you point it at your server's URL. Don't have one? Start your own in one command on any machine with Node 18+:

npx annotex-server

It prints an admin token to paste here and an admin URL to invite colleagues. Details: annotex-server. Then see Configure and Network use & privacy below.

What it does

• Adds a command "Publish current note" (and a ribbon icon).
• Renders the current note on your server at https://<your-server>/n/<docId> and copies the share link to your clipboard.
• Gives each note a stable docId (stored in frontmatter as annotex-doc), so renaming the file — or re-publishing after edits — keeps the same comment thread.
• Publishing again updates the published page; comments survive edits (Annotex re-anchors them by quoted text).
• Mirrors annotations back into your vault. Each published note gets a <note>.annotex.json file right beside it holding all its highlights and comments. It's refreshed automatically whenever you open or publish the note (and on demand via "Sync annotations to vault"), so the discussion travels, versions, and backs up together with the note. The Annotex server stays the live hub colleagues comment against in real time; the sidecar is your owned, offline copy of it.

Install

Once it's in the Community Plugins store, install it the normal way: Obsidian → Settings → Community plugins → Browse → search Annotex → Install → Enable. Until then, use one of the manual options below.

Option A — from the latest release (no build tools needed)

1. Download manifest.json and main.js from the latest release.
2. In your vault, create the folder <vault>/.obsidian/plugins/annotex-publish/ and put both files in it. (.obsidian is hidden — on macOS press Cmd-Shift-. in Finder to show hidden folders.)
3. In Obsidian: Settings → Community plugins → Reload, then enable Annotex.

Option B — via BRAT (auto-updates from this repo)

Install the BRAT community plugin, then Add beta plugin → epipolarstudios/annotex-obsidian-plugin. BRAT tracks new releases for you.

Option C — build from source

git clone https://github.com/epipolarstudios/annotex-obsidian-plugin
cd annotex-obsidian-plugin
npm install && npm run build      # produces main.js

Then copy manifest.json + main.js into <vault>/.obsidian/plugins/annotex-publish/ and reload + enable as in Option A.

After any manual update, Settings → Community plugins → Reload (or toggle the plugin off/on) is what picks up the new main.js.

Configure

Settings → Annotex:

• Annotex server URL — the base URL of your Annotex server, e.g. https://annotex.example.com.
• Publish token — generate one in your server's admin panel (/admin → Publish tokens → Generate) and paste it here. It authorises publishing only (not managing access) — safer than your master admin token. The plugin keeps it in this vault's plugin data, on the device running Obsidian — it's only ever sent to your server, never anywhere else. Treat it like a password; don't sync it to a shared vault. (Your master ADMIN_TOKEN also works here, but a scoped publish token is preferred.)

Network use & privacy

This plugin makes network requests only to the Annotex server URL you configure — no other remote services, no third parties, and no analytics or telemetry of any kind.

• On publish it sends the current note's Markdown to your server (PUT /api/documents/…), authenticated with your publish token.
• On open / sync it fetches that note's annotations from your server (GET /api/annotations/…) to mirror them into the vault.

Nothing is sent anywhere else. The plugin is a companion to a self-hosted Annotex server that you run and control, and does nothing until you point it at one.

Required configuration (disclosure): the plugin needs an Annotex server URL and a publish token to function. It only reads/writes files inside your vault (the note it publishes, and a <note>.annotex.json mirror beside it) — never outside.

Use

Open a note → run "Publish current note" (Command palette, or the ribbon icon) → the share link is copied to your clipboard. Send it to an invited colleague (add them first in the Annotex admin panel). Edit and re-publish any time; the link and its comments stay.

Support

If Annotex is useful to you, you can support development:

Notes & limits (v0.2)

• The <note>.annotex.json sidecar is currently a one-way mirror (server → vault): it's a durable, versioned copy of the comments, but it isn't yet re-imported to rebuild the server from the vault. Keep it in your vault backup; automatic restore-on-publish is a planned follow-up.
• Obsidian wikilinks are flattened to their display text ([[Note|Alias]] → Alias); embeds ![[...]] are dropped. Standard Markdown + $…$/$$…$$ math render fully.
• Publishing is admin-authenticated, so anyone who can run this plugin with your token can publish. Keep the token private.
• The published note is only viewable by invited Annotex members — it is not public.
