About Underscored
For the ideas you find
while reading — and the
people you want to share
them with.
Underscored is where great passages live. Save anything worth keeping, share it beautifully, and discover what the people you follow are reading.
Save from anywhere
Highlight text in Safari or any app, tap Share, tap Underscored. Your clip is saved instantly — source attached — and you're back to reading. Two taps. Zero interruption.
On desktop, the Chrome extension works the same way — highlight any text on the web and save it in one click. No screenshots needed.
Get the Chrome extension →Clip from YouTube
The Chrome extension adds a transcript panel to every YouTube video. Click any line — or select a range — and save it as a clip with the video title and timestamp attached automatically.
Ideas don't only live in articles. Now they don't have to stay in videos either.
Clip from the physical world
Point your camera at any printed text — a book, a magazine, a newspaper — and Underscored captures the passage instantly. No typing. AI identifies the author and source automatically.
On iOS, you can also share a screenshot directly to Underscored — we'll extract the text and identify the source for you. And if you have saved screenshots already, use Scan Saved Screenshots to import them all at once.
Try scanning →Share cards worth posting
Every clip generates a beautiful image card — the passage, the source, and the article's cover image, composed automatically. Dark, light, or event themes. Landscape, square, or story formats.
Beautiful enough to post on its own. Every card shows underscored.ai — so every share is a discovery moment for someone new.
Follow great readers
Follow people whose taste you trust and see what they're saving in your Following feed — what your people are reading. Discover ideas you didn't know you needed, from people whose judgment you value.
Browse the Discover feed to see public clips from all readers. Tap any username to see their full library.
Browse Discover →Context on every clip
Every clip arrives with meaning attached. Clips saved from URLs carry context from the source. Clips from books or physical pages get AI-generated context — background on the author, the work, and the moment it was written.
Search by meaning
Search understands what you mean, not just the exact words you typed. Type "resilience" and surface clips about stoicism, perseverance, and fortitude. Your entire library — passages, authors, titles, and tags — is searchable.
Get started free →Collections
Group clips into themed collections — by project, subject, or wherever your thinking is going. Collections can be public or private. Public ones live on your profile page at underscored.ai/username.
Get started free →iOS app — private beta
The Underscored iOS app is currently in private beta. The full experience — share extension, scan, share cards, and your Following feed — built for iPhone.
Request access and we'll be in touch.

This year, with tools that didn't exist back then, I finally got to finish it — and it turned out better than I imagined it could be. It's for anyone who has ever read something worth keeping and lost it. I hope you enjoy.
