Ravenote is a Chrome extension that helps you take notes on Udemy courses. It reads lecture transcripts from the Udemy page you're viewing and uses AI to generate structured notes, quizzes, and summaries.
We do not collect any personal data. Ravenote has no user accounts, no analytics, and no tracking. We do not know who you are or what courses you take.
All your data is stored locally on your device using Chrome's built-in storage API:
This data never leaves your browser unless you explicitly export it.
When you generate notes, quizzes, or summaries, Ravenote sends the lecture transcript text to OpenRouter (openrouter.ai) for AI processing. This is the only external service Ravenote communicates with.
What is sent:
What is NOT sent: your name, email, browsing history, or any data from pages other than the Udemy lecture you're viewing.
OpenRouter's privacy policy governs how they handle data sent to their API. We recommend reviewing it at openrouter.ai/privacy.
Ravenote requests the following Chrome permissions:
You can delete all your data at any time using the "Clear all" button in the Ravenote popup, or by uninstalling the extension. Since all data is stored locally, uninstalling removes everything permanently.
If we make changes to this privacy policy, we will update the date at the top of this page. Major changes will be communicated through the extension's update notes on the Chrome Web Store.
