About

Index

Read full description

Index is a visual workspace for designers, creatives, and brands — built to close the gap between saving and doing. Save anything in a tap — links and images — from any app with the share sheet. Everything lands in your inbox, captured now and sorted on your terms later. Then put it to work: • Inbox — triage new saves instead of losing them in a pile • Folders — give every save a clean home • Boards — curate visual collections • Projects — gather saves into the work you're actually shipping • Tags — label across everything and resurface it instantly Your inspiration stops scattering across screenshots, bookmarks, and a dozen other apps — and starts being something you can actually use. Index is in private beta. You're early, and your feedback shapes where it goes.
