Copilot for Obsidian

Simple, local-first, open source AI copilot for Obsidian

Obsidian Downloads

Copilot for Obsidian is a free and open-source ChatGPT interface right inside Obsidian. It has a minimalistic design and is straightforward to use.

  • 💬 ChatGPT UI in Obsidian.
  • 🛠️ Prompt AI with your writing using Copilot commands to get quick results.
  • 🚀 Turbocharge your Second Brain with AI.
  • 🧠 Talk to your past notes for insights.

My goal is to make this AI assistant local-first and privacy-focused. It has a local vector store and can work with local models for chat and QA completely offline! More features are under construction. Stay tuned!

🛠️ Features

  • Chat with ChatGPT right inside Obsidian in the Copilot Chat window.
  • No repetitive login. Use your own API key (stored locally).
  • No monthly fee. Pay only for what you use.
  • Model selection of OpenAI, Azure and local models powered by LocalAI.
  • No need to buy ChatGPT Plus to use GPT-4.
  • No usage cap for GPT-4 like ChatGPT Plus.
  • One-click copying any message as markdown.
  • One-click saving the entire conversation as a note.
  • Use the active note as context, and start a discussion around it by switching to "QA: Active Note" in the Mode Selection menu.
    • This feature is powered by retrieval augmentation with a local vector store. No sending your data to a cloud-based vector search service!
  • Easy commands to simplify, emojify, summarize, translate, change tone, fix grammar, rewrite into a tweet/thread, count tokens and more.
  • Set your own parameters like LLM temperature, max tokens, conversation context based on your need (pls be mindful of the API cost).
  • User custom prompt! You can add, apply, edit, delete your custom prompts, persisted in your local Obsidian environment! Be creative with your own prompt templates, sky is the limit!
  • Local model support for offline chat and QA using LocalAI. Talk to your notes without internet! (experimental feature)

📝 Planned features (based on feedback)

  • Support embedded PDFs as context
  • Integration with ElevenLabs or Bark to let the AI speak like human
  • Unlimited context for a collection of notes.
  • Retrieval augmented generation (RAG) with your vault. Explore, brainstorm and review ideas like never before!
