YTSK - Chrome Web store

YTSK (Smart AI YouTube Summarizer) is a tool that uses artificial intelligence to give you short summaries of YouTube videos. It connects to your personal Gemini API key from Google AI Studio. This means you don't have to pay for a monthly subscription, and you can manage your own costs.

Benefits

YTSK helps you save time by quickly giving you the main points of a YouTube video. You can choose different AI models like Gemini 2.5 Flash, 3.0 Flash, or Pro, depending on whether you need a fast summary or a more detailed one. You can also create your own instructions for the summary, telling the AI exactly how you want it presented, like a short overview or a list of tasks. It works in over 15 languages, so you can get summaries in languages like Korean, Japanese, Chinese, Spanish, and French. YTSK can pull information from official subtitles or automatically generated transcripts. You can easily share your summaries to social media like X or Threads, or copy them along with the full transcript.

Use Cases

This tool is great for students and professionals who need to understand video content quickly. Content creators can use it to find new ways to use their video material. Language learners can benefit from summaries in different languages. It's also useful for people who like to adjust AI settings to their specific needs.

Pricing

There are no monthly subscriptions. Users connect their own Gemini API key from Google AI Studio, allowing them to control costs.
