Index: Save Anything

Save links, notes, and documents in seconds. Index turns scattered context into a personal knowledge base you can explore through grounded, cited conversations.

Save anything. Think with everything.

Index is a personal knowledge workspace for the context you do not want to lose. Share a link, note, or document from your iPhone, and it becomes part of a calm, organized brain you can return to later.

ASK YOUR BRAIN Discuss complex ideas across everything you have saved. Index grounds answers in your own context and links citations back to each source.

CAPTURE WITHOUT BREAKING FOCUS Use the iOS share sheet to save useful links, selected text, files, and quick notes in seconds.

TURN LINKS INTO CONTEXT Index extracts readable page content, creates a concise summary, and keeps your own note beside it.

STAY IN CONTROL Your account syncs across devices. Delete individual items and conversations whenever you want, or permanently delete your account and its captures, files, chats, and feedback from inside the app.

Built for founders, researchers, and knowledge workers who want less friction between finding something useful and thinking with it.
