# Aider in your browser

[Aider browser UI demo video](/content/assets/aider-browser-social.mp4)

Use aider’s new experimental browser UI to collaborate with LLMs to edit code in your local git repo. Aider will directly edit the code in your local source files, and [git commit the changes](/content/docs/git.html) with sensible commit messages. You can start a new project or work with an existing git repo. Aider works best with Claude 3.5 Sonnet, DeepSeek R1 & Chat V3, OpenAI o1, o3-mini & GPT-4o. Aider can [connect to almost any LLM, including local models](/content/docs/llms.html).

Use the `--browser` switch to launch the browser version of aider:

```
python -m pip install -U aider-chat

export OPENAI_API_KEY=<key> # Mac/Linux
setx   OPENAI_API_KEY <key> # Windows, restart shell after setx

aider --browser
```
