Bring your own AI

Blocwrite works with OpenRouter (cloud models) or LM Studio (local models). Pick one in the app under Profile → AI — both stay fully supported.

OpenRouter (cloud)

Use hundreds of models via your own API key. Keys and requests go between your browser and OpenRouter — Blocwrite does not bundle credits.

  1. Create an account at openrouter.ai and create an API key.
  2. In Blocwrite: Profile → AI → choose OpenRouter, paste your key, then Refresh models and pick one.
  3. Optional: change Base URL only if you use a proxy; default is https://openrouter.ai/api/v1.

Many models have free tiers on OpenRouter; you control cost and model choice.

LM Studio (local)

Run models on your machine. No OpenRouter key needed for this path — switch provider in Settings whenever you want cloud models again.

  1. In LM Studio: load a model and start the server (Developer tab).
  2. In LM Studio: open Server Settings and turn on Enable CORS.
  3. In Blocwrite: Profile → AI → choose LM Studio (local), paste the Base URL from LM Studio’s Local Server panel, then pick your model.

Safari blocks local HTTP — use Chrome or Firefox. If Brave fails, disable Shields for this site.
