Gistilo

Gistilo is a YouTube video summarizer aimed at researchers, students, content creators, and anyone with too many videos and not enough time to watch them. A user pastes a YouTube link and receives either 7 key insights or a detailed summary instead of a long transcript, and can optionally verify claims made in the video against outside sources.

The tool works by analyzing a pasted YouTube link or the video a user is currently watching through its Chrome extension, then generating a structured summary. Usage is measured by video duration, rounded up to the nearest minute, so a 7:30 video counts as 8 minutes against a user's monthly allowance.

Gistilo produces an executive summary with labeled sections and highlighted key claims rather than a flat list of bullets, supports videos up to 5 hours long on its Pro plan, skips sponsor segments, and can export summaries as clean PDFs. Optional fact-checking verifies key claims against sources and clearly labels anything it cannot verify.

The free plan covers 6 hours of video per month, videos up to 90 minutes long, and 3 fact-checks a month, while the Pro plan at $7/month covers 80 hours of video per month, videos up to 5 hours long, and 100 fact-checks a month. A browser extension is available free for Chrome, Edge, Brave, Arc, and Opera, and included hours reset each billing cycle.
