AI Note Assistant: Joplin Plugin

An AI-powered chat panel for Joplin that lets you have a conversation with your notes. Ask questions, get summaries, brainstorm ideas, and dig into your knowledge base, all without leaving the editor.

Features

  • Chat with your notes: Ask anything and the assistant answers using the content of your Joplin notes as context.
  • Attach specific notes: Click the 📎 button or type @ in the message box to pick and attach individual notes to a prompt, so the AI focuses only on what you choose.
  • @ mention autocomplete: Type @ followed by any part of a note title to get an instant searchable dropdown. Select a note to pin it to the message.
  • Conversation memory: The assistant remembers the full back-and-forth within a session, so you can ask follow-up questions naturally.
  • Secure API key storage: Your Cohere API key is encrypted with AES-256-GCM (random 96-bit IV per save) before being stored, it is never kept in plain text.
  • Theme aware: Automatically adapts to your Joplin theme (Light, Dark, Dracula, etc.) using native CSS variables.
  • Keyboard friendly: Press Enter to send, Shift+Enter for a new line, and navigate the note picker entirely with the keyboard.

Installation

Via Joplin Plugin Marketplace (Recommended)

  1. Open Joplin and go to Tools › Options (or Joplin › Settings on macOS).
  2. Click Plugins in the left sidebar.
  3. Search for joplin-plugin-ai-note-assistant.
  4. Click Install and restart Joplin.

Manual Installation

  1. Download the .jpl file from the GitHub Releases page.
  2. In Joplin, go to Tools › Options › Plugins.
  3. Click the gear icon (top right) and select Install from file.
  4. Select the downloaded .jpl file and restart Joplin.

Setup

This plugin requires a free Cohere API key to work.

  1. Sign up or log in at dashboard.cohere.com/api-keys.
  2. Create a new API key and copy it.
  3. In Joplin, open the AI Note Assistant panel and switch to the ⚙️ Settings tab.
  4. Paste your key into the API Key field and click Save & Encrypt.
  5. The status row will confirm API key is configured.

How to Use

Once installed and configured, the AI Note Assistant panel appears automatically on the side.

Asking a question (no attachment)

Type your question in the input box and press Enter. The assistant will use up to 30 of your most recent notes as background context to answer.

Attaching specific notes

  1. Click the 📎 button next to the input box to open the note picker dropdown.
  2. Search by title and click a note to attach it. Repeat for multiple notes.
  3. Attached notes appear as chips above the input. Click × on a chip to remove one.
  4. Send your message — the assistant will use only the attached notes as context, giving you a more focused answer.

@ mention shortcut

Type @ directly in the message followed by part of the note title (e.g. @project plan). The picker opens automatically. Select a note with the mouse or keyboard — the @query text is removed and the note is attached as a chip.
