Luminar: AI Summaries for Videos & Articles

Summarize YouTube videos with subtitles and web pages with readable text into linked digests, diagrams, and PDF export.

A digest for captioned videos and readable web pages. Luminar turns YouTube videos with subtitles and web pages with readable text into a scannable, editorial digest, right where you are reading or watching. No new tabs. No pasting transcripts into a chatbot. One click gives you a map of the content, titled sections, and key ideas presented as clean diagrams when the source supports them. It is built for people with more to watch and read than time. What you get - A proportional map of the video or article, so you can see its shape before you commit to it. - Titled, linked sections. Skim the structure in seconds, then jump straight to the exact moment in a video or the passage in an article. - Diagrams for comparisons, timelines, and processes when the source contains structure worth visualising. - An editorial summary that reads like a sharp briefing, not a bullet dump. - Export the digest to a PDF to keep or share. - A light and dark theme that follows the page you are on.
