Lotse is a coding agent for your GitHub repositories.
Describe a change on your phone. Lotse works on it in the cloud, runs your tests and opens a pull request for you to review, even when the app is closed. You get a push when it's ready.

Lotse works best on small, well-defined changes. Repositories that need a database or a browser to test, and Android, Ruby, PHP or .NET projects, are limited. Lotse says so in the pull request.
The current limits are shown in the app. Lotse Pro is an auto-renewing subscription billed by Google Play or the App Store; cancel any time in your store's subscription settings.
Before your first task the app asks for your consent: your task description and the repository code are sent to AI model providers via OpenRouter to do the work. AI output can be wrong, so always review a pull request before you merge it. Details are in the privacy policy.
Lotse is the new name of Jules Console. Same app, same account, and your Pro subscription carries over. Google ends Jules on December 31, 2026; if you used Jules in this app, your sessions stay viewable until then.
