SummYT (formerly YouTube Summarized) vs SumlyAI

SummYT (formerly YouTube Summarized) turns long YouTube videos into short summaries you can read in seconds. Paste a video link on summyt.app and get a skimmable recap, full transcript, and a chat panel where you can ask questions about the content. Summaries, transcripts, and chats save to a personal library so you can return without re-processing the same video.

Most YouTube summarizers give you a one-time text dump and nothing else. SummYT keeps everything in one workspace: summary, transcript, and chat tabs for the same video, plus a browser extension for Chrome and Edge that works while you are already on YouTube. That library layer matters when you are working through a lecture series or research playlist and need to reference earlier videos days later.

Students, researchers, and professionals use SummYT to preview lectures, tutorials, and interviews before committing to a full watch. The site supports English, Spanish, Portuguese, and Turkish. A playlist length calculator is also available as a separate tool. The Chrome and Edge extensions let you summarize and save videos without leaving the YouTube page.

SumlyAI sends personalized podcast summaries to your inbox after new episodes drop. You build a profile with your interests and goals, pick shows to follow, and receive takeaways framed for your context instead of generic bullet recaps.

Most summarizers compress episodes into the same highlights for every listener. SumlyAI filters for mental models and actionable advice tied to your profile, delivers within 12 hours of release, and targets a morning briefing workflow so you can skim a 3 minute note instead of a 2 hour episode.

It fits founders, operators, and lifelong learners who subscribe to long-form shows but forget details by the next week. The homepage lists 1,017+ users, a free plan with no credit card required, and a 14 day free trial on the Premium Starter tier.
