Users can track how lifestyle changes like supplements, workouts, or sleep affect their cognitive performance over time. Cogmi supports both individuals and teams aiming to improve productivity and mental well-being by aligning tasks with real-time brain function.

YTSummary is a YouTube video summarizer that pulls ChatGPT summaries from any link so you can skip hour-long lectures, podcasts, and conference talks. Paste a URL on ytsummary.app or use the Chrome extension while watching, then pick Outline mode for key highlights, Mind Map mode for a hierarchical visual, or Segment mode for timestamped breakdowns aligned to chapters and key moments.

Most YouTube summarizers spit out one flat paragraph. YTSummary splits output by mode so students get quick overviews, researchers get segment-level detail, and visual learners get mind maps showing how ideas connect. It handles videos of any length on paid tiers and supports custom summary languages plus exports to image and PDF formats.

Students, researchers, marketers, and content writers use it to digest lectures, conference talks, podcasts, and competitor videos without sitting through full runtimes. The free tier includes 10 summary credits with no credit card required, while Basic and Pro plans raise monthly caps and remove video length limits.
