AI Summarizer for YouTube (Mac App Store)

Long YouTube videos are full of valuable information — but who has time to watch them all the way through? InsightKeeperAI YouTube Summarizer is a free AI tool that converts lengthy YouTube videos into three distinct types of summaries: a quick summary for the key takeaways, a sequential summary that walks through the content in order, and deep-dive questions to help you think more critically about the material. It runs locally on Mac, which means your data never leaves your device — full privacy guaranteed. Save time, cut through information overload, and get the insights you actually need, faster.
