Research that remembers the assignment
Keep sources attached to the question, project, or decision that made them useful.
The context layer for your life
Your best thinking,
finally indexed.
Save anything from Mac or iPhone. Index keeps the source, the screen, and the thought behind it—then helps you think across everything you know.

Prioritize the onboarding rewrite. Three saved sources point to the same friction: people understand capture, but not the payoff.

THE PROBLEM ISN’T SAVING
The link was never the valuable part.
The valuable part was the thought it sparked, the decision it informed, and the work it connected to. Index keeps that thread intact.
ONE CONTINUOUS WORKFLOW
From “save this” to
“use this.”
Capture without changing apps. Add the context future-you will need. Ask Index to bring the right ideas back when the work demands them.
Mac quick capture
Two taps. The whole moment.
Index captures the active window, readable text, and browser URL without pulling you away from the work.
⌘⌘Save screen context
Personal context
Keep the thought behind it.
A third tap opens a quiet composer over whatever you’re doing. Add a sentence, save it, and keep moving.

Grounded discussion
Ask the question behind the question.
Index retrieves the relevant memories, answers from your own material, and shows the sources that shaped its response.

The overlooked cost
of context switching
Great work compounds when the reason behind an idea stays attached to the idea itself.
The real unit of knowledge is not the link. It is the link plus the context that made it matter.

QUESTIONS, ANSWERED
The important details.
What can I save to Index?+
Links, selected text, screenshots, notes, PDFs, files, social posts, and content shared from supported Mac and iPhone apps.
Does Index use what is on my screen?+
Only when you trigger quick capture and grant macOS Screen Recording permission. Index captures the active window so it can preserve readable context; you can review and delete the resulting memory.
Can I edit or delete my memories?+
Yes. Memories can be edited or deleted individually, and you can delete your complete account and its stored content from the app.
Can I use one subscription on Mac and iPhone?+
Yes. Sign into the same Index account and your access and personal index follow you across both platforms.
