Gistly
Gistly is a productivity-focused YouTube video summarizer delivered mainly as a Chrome extension that adds a summary panel to watch pages. Install it once, open any video, and it returns TLDR summaries, key insights, timestamped breakdowns, and transcripts without leaving YouTube. The Dumpling Software team also runs free web utilities on gist.ly for transcripts, SEO article drafts, and FAQ generation.
Most summarizers ask you to paste a URL into a separate site. Gistly stays inside the player and places its widget where YouTube ads usually sit, which keeps lecture binges and news catch-up in one tab. The trade-off is scope: only YouTube URLs count, so podcasts or uploads outside YouTube are not supported unless they are published there.
Summaries run on OpenAI GPT models, including GPT-4 per the extension listing, and the Chrome listing cites about 7 seconds of processing per video. Output can be translated into 40+ languages, shared as links, or fed into gist.ly generators that turn a watch page into a blog-ready article. Gistly states it can handle videos up to 4 to 6 hours before hard technical limits appear.
Students, content creators, and product managers quoted in on-site reviews use it to skim long explainers and interview clips faster. Paid upgrades route through Lemon Squeezy checkout linked from gist.ly, while the transcript, article, and FAQ tools on the site stay free to try.
