Turn videos, articles, PDFs, papers, and audio into clear briefings, cited syntheses, and a library you can return to. 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
Works on videos and articles
Open a YouTube video with available subtitles and Luminar reads the transcript. Open a Wikipedia page, essay, long read, documentation page, or other web page with readable text and Luminar extracts the text. Either way you get a clear digest tied back to the source.
How it works
1. Open a long video or article. 2. Click Luminise, right on the page. 3. Read the digest. Jump to the source where it matters. Export a PDF if you want one.
Free to start
Luminar is free and needs no account to get going. Add it to Chrome and try it on the next long thing you were about to half-watch.
Who it is for
Students working through lectures and long reads. Researchers triaging talks and papers. Engineers and PMs cutting through documentation. Anyone who saves long videos and articles they never quite get back to.
