Permissions:
This extension allows you, after clicking the “Crop” button, to capture an image of the video player in the active tab.
The permission “Read and change all your data on the websites you visit” might appear very broad, but we request it solely to:
detect the YouTube video player in the page you’re on;
capture the visible screenshot of the video to let you select and crop the region you want;
we do not access or transmit any other webpage data or content without your explicit action.
The process is entirely under your control: you click the button, you select the area, you confirm the crop.

- Contextly has become my go-to extension for YouTube. As someone who watches a lot of tutorials and lectures, the AI summaries save me so much time. I especially appreciate the Bring Your Own Key option because it lets me use my own OpenAI API while keeping my data private. The chat feature works smoothly right inside the player, and asking questions about long videos feels like having a study buddy on demand. It is not perfect, the interface can feel a bit cluttered at first, but the time it saves makes it totally worth it. Highly recommend for students or anyone who learns from YouTube.

- Beatrice Melo
- Very convenient; the automatic summary dialogue saves me a lot of time, especially for long videos.
- David Schulte
- Very suspicious extension. The author mails random extension store developers and ask for 5 star reviews. I looked at the source and it is a vibe coded mess. All it does is taking the YouTube generated transcript and chapter overview into a Vercel Api builds a chat bot around it. The code mentioned a expensive subscription service with Standard, Premium and Unlimited models (https://contextlyapp.com/payments). The page is also not working and vibe coded. Again you can do this free in ChatGPT.
