Installing

For installation you have two options (you need to choose only one):

First option: Using Built-in AI in Chrome 138+:

1. Install Chrome 138 or above
2. That's all. Use the extension. You might need to wait the first time while the model is loading, but further interactions should be almost instant (although it depends on your hardware, of course).

If something goes wrong reload the page, if it doesn't work please open an issue.

Second option (more advanced): Using local installed Ollama server (you need 16GB RAM or more):

1. Install Ollama
2. Install ollama3.1 model:

Open terminal and run:

ollama run llama3.1

3. Set CORS headers:

For macOS open terminal and run:

launchctl setenv OLLAMA_ORIGINS "*"

For other OS please check this

4. Restart Ollama server:

for macOS: click on the Ollama icon in the menu bar and click "Quit Ollama" and then run Ollama from the Launchpad (or Applications folder) again.
