What YouTLDR is

YouTLDR is an AI tool for working with YouTube videos through transcripts, summaries, timelines, chat, translation, and repurposing outputs. You can paste a YouTube URL on the main site or use the Chrome extension to open the toolkit directly inside a watch page.

The product is designed for people who need more than a short summary. Its workflow keeps every key point tied to a timestamp, offers a live transcript cursor during playback, and supports outputs such as blog posts, social drafts, slide decks, study notes, and quizzes.

Core features

Transcript, summary, timeline, and chat

Paste a YouTube URL or use the browser extension to generate a transcript, summary, timeline, and chat view from the same video source.

Timestamped evidence

Every summary point links back to the exact timestamp in the video, and the live transcript cursor follows playback so you can verify claims quickly.

Chrome extension inside YouTube

The Chrome extension opens a side panel inside YouTube with the full toolkit, including searchable transcript, AI summary, timeline, and interactive chat.

125+ language support

YouTLDR translates transcripts and summaries in 125+ languages, letting you work across multiple languages from the same video.

Repurposing outputs

The repurposing tools convert videos into blog posts, LinkedIn posts, X threads, slide decks, chapter lists, study notes, quizzes, and Shorts ideas.

Saved video history

Saved videos keep their transcript, summary, and chat in history so they can be reopened and searched later.

Common use cases

Study or research a lecture
Turn a long YouTube video into timestamped notes so you can review the main points without losing the original evidence trail.
Repurpose video into publishable content
Extract key moments from interviews, talks, or tutorials and repurpose them into blog posts, LinkedIn updates, X threads, or slide outlines.
Ask questions about a video
Use the transcript and chat to ask specific questions about a video when you need a precise answer from a long recording.
Watch and analyze in YouTube
Work directly inside the YouTube player with a side panel, so you can summarize, translate, and jump between moments without switching tabs.
Reopen and search prior analyses
Save videos to history so you can revisit transcripts, summaries, and chats later instead of rebuilding the analysis from scratch.
