Quick Answer

Obsidian + Ollama + a community plugin pointed at Ollama's local OpenAI-compatible endpoint is the simplest private setup. LM Studio works the same way if you prefer a GUI. Target 32GB of RAM for comfortable headroom running a 7B–14B model alongside Obsidian.

  • β–ΈBest setup: Obsidian + Ollama, connected through a community plugin
  • β–ΈBest plugin approach: any community plugin supporting a configurable OpenAI-compatible local endpoint
  • β–ΈBest for privacy: keep both the model and the API endpoint on your own machine β€” verify it, don't assume it
  • β–ΈBest hardware target: 32GB RAM for comfortable local LLM use alongside Obsidian

Key Takeaways

  • βœ“Best overall: Obsidian + Ollama, connected via a community plugin
  • βœ“Best alternative: Obsidian + LM Studio, if you want a GUI for testing models
  • βœ“No cloud API required β€” everything runs through a local endpoint once configured correctly
  • βœ“32GB RAM is a good hardware target for running Obsidian alongside a 7B–14B local model
  • βœ“Check plugin maintenance and confirm the local endpoint before trusting a plugin with your vault

Best Setup: Obsidian + Ollama

If you already use Obsidian and want private AI inside your vault, Obsidian + Ollama connected through a community plugin is the setup to start with. The chain is simple: Obsidian β†’ a community plugin β†’ Ollama β†’ your local model. Ollama exposes an OpenAI-compatible API on your machine by default, and compatible Obsidian plugins talk to that same standard, so the request never leaves your device.

LM Studio works the same way and is the better pick if you want a graphical interface for downloading and testing models before wiring one into Obsidian β€” see the comparison below.

Use this if: you want a simple, well-documented local AI backend with broad plugin support. Skip it if: you need a GUI for model management, or you're not ready to check a community plugin's maintenance quality before relying on it daily.

Ollama vs LM Studio

Both expose a local OpenAI-compatible API and both work with Obsidian plugins that support a configurable endpoint. Choose Ollama if you want a simple, script-friendly local backend. Choose LM Studio if you prefer a graphical interface for browsing, downloading, and testing models before pointing a plugin at them.

Which Plugin Should You Use?

Don't treat any single plugin as a permanent winner β€” the Obsidian community plugin ecosystem changes quickly, and maintenance quality varies considerably from one plugin to the next.

  • β–Έ**Update activity:** a plugin last updated long ago may stop working as Ollama's or LM Studio's API changes over time.
  • β–Έ**Local endpoint support:** verify the API endpoint field is genuinely configurable β€” some plugins claim general compatibility but are hard-coded to a specific cloud provider.
  • β–Έ**Streaming responses:** a plugin that only supports non-streaming requests feels noticeably slower on longer replies.
  • β–Έ**Vault/context access:** some plugins can pull context from your existing notes to include in prompts; others only work with manually typed input β€” decide whether that matters for your use case before picking one.

How Much Hardware Do You Need?

Obsidian itself is lightweight β€” the hardware requirement is really about the local model you run alongside it.

Is It Actually Private?

Yes β€” if the entire chain stays local: Obsidian β†’ plugin β†’ localhost β†’ Ollama or LM Studio β†’ your local model. Your notes never need to leave the machine.

Don't assume this automatically, though. Verify the plugin is pointed at a genuine localhost endpoint and isn't silently falling back to a cloud API β€” check its settings and, if you want to be certain, its network activity.

Frequently Asked Questions

Do I need an API key to connect a local LLM to Obsidian?β–Ύ
No β€” a purely local setup, where both the plugin and the model run on your own machine, doesn't need cloud authentication. Some plugins still show an API key field, but it can typically be left blank or filled with a placeholder value for local connections.
Will my notes leave my machine if I use a local LLM plugin in Obsidian?β–Ύ
No, as long as the plugin is genuinely pointed at a local endpoint and not silently falling back to a cloud service. Verify the configured address is a localhost URL, and check the plugin's network activity if you want to confirm no external requests are being made.
Ollama or LM Studio β€” which should I use with Obsidian?β–Ύ
Both expose a local OpenAI-compatible endpoint that Obsidian plugins can connect to. Ollama is the simpler, more script-friendly default; LM Studio is the better pick if you want a graphical interface for browsing and testing models before wiring one into Obsidian.
What hardware do I need to run a local LLM alongside Obsidian comfortably?β–Ύ
Obsidian itself is lightweight, so the hardware requirement is really about the local model. 32GB of RAM is a comfortable target for a 7B–14B model running alongside Obsidian β€” see our VRAM and RAM sizing guides for model-specific requirements.
