Description
YouTube Summary with AI is a Chrome extension that adds instant text summaries to YouTube videos. Its own site frames the pitch directly: no AI account and no API key required, so a viewer installs it and gets a summary without signing up for a separate AI service first.

The extension works by generating a text summary of a YouTube video's content, letting a viewer quickly understand the main points before deciding whether to watch it in full, or instead of watching it at all. This suits learners going through long lecture or tutorial videos, and professionals scanning through longer talks or interviews for the parts that matter to them.
The free tier gives seven summary quotas per week, with a limit on transcription length per summary. A Pro tier, priced at $9.90, adds 300 quotas and removes the transcription-length limit, giving access to unlimited transcription words per summary. A separate subscription, priced at $14.90 a month with a yearly option that discounts the annual price, removes the quota limit entirely for unlimited summaries alongside the same unlimited transcription length. Users can manage or cancel a subscription from their account profile page.
The extension is developed by LELU TECH LTD, a Hong Kong-based software company, which lists the tool among a small set of its own browser-extension products, including a listed partner tool called flowprompter.
Because it runs as a browser extension rather than a standalone app, it works directly on YouTube's own video pages, adding a summary option without the viewer needing to copy a video link into a separate website or tool. That also means the extension only works where it is installed and signed in through the browser, rather than through a separate account system, which is part of how it avoids requiring a separate AI account or API key in the first place. For someone who watches a lot of long-form video, whether lectures, interviews, or tutorials, the extension's main value is time: a summary takes seconds to read against a video that might run well past an hour.
