You-tldr

You-tldr is a TikTok video summary tool that turns any YouTube video into a verifiable summary in seconds. YouTLDR converts YouTube videos into live transcripts, timestamped summaries, interactive chat, and repurposed content in 125+ languages. It targets creators, students, and researchers who need verifiable takeaways and a searchable library, with processing gated behind a Pro subscription.

YouTLDR is a YouTube-focused summarization and repurposing tool that converts any public video into a live transcript, a timestamped AI summary, a navigable timeline, and an interactive chat. Pasted URLs or the Chrome extension trigger processing: the transcript scrolls in step with playback, each summary key point links to the exact moment it was drawn from, and markers appear on YouTube's own progress bar. Users can ask questions with the full transcript as context, then export the transcript, translate it into more than 125 languages, or generate one of six output formats (blog post, LinkedIn post, X thread, slide deck outline, chapter list, Shorts ideas). Study notes and quizzes are also available for lecture content. The product is aimed at people who treat video as working material rather than background noise. Content creators repurpose research calls and conference talks into written assets. Students turn recorded lectures into notes and practice questions. Researchers pull findings out of interviews and conference sessions while keeping the evidence trail intact. The Chrome extension places the same transcript, summary, timeline, and chat panel directly in the YouTube watch page, so the workflow stays inside the platform where the video lives. YouTLDR positions itself against YouTube's built-in Ask button and general-purpose assistants by emphasizing verifiability and persistence. Summaries are not handed over as a wall of bullets to be trusted; every claim is tied to a timestamp, and each processed video is saved to a searchable library with its transcript, summary, and chat history. The output formats go beyond a single reply, producing drafts and decks that can be edited and published. A practical constraint shapes the experience: browsing public transcript pages is free, but processing a new video requires an active Pro subscription. The tool handles videos with captions or audio, including auto-generated captions, and also accepts uploaded audio or video files. For teams and individuals who need to audit claims, translate foreign-language talks, or extract multiple content formats from one source, it is a focused alternative to broader AI note takers.
