Personal AI memory · macOS

One brain for everything you've already saved.

Your email, notes, slides, code, voice memos, and chat history live in a dozen places. Neostriatum indexes them where they already are — and answers any question across all of them at once. No migration. Your data.

Live today across 6 surfaces. Apple Photos, Apple Notes, and ChatGPT history coming next.

The problem

You have the information. You just can't find it across all the places it lives.

The answer is somewhere — an email, a slide, a note, a voice memo, a ChatGPT thread from three weeks ago. Search one app and you only see one app. The connections never surface, so the same question costs you ten minutes, every time.

Gmail the thread you half-remember
Slides the number you presented once
Obsidian the idea you wrote down
Voice the thing you said out loud
Code the decision in a commit
ChatGPT the answer you got, now lost
How it works

Three steps. No migration. It reads the life you already have.

1

Connect your surfaces

Point Neostriatum at the places you already work — email, your Obsidian vault, slides, code, voice transcripts. It reads them in place. You move nothing.

2

It builds one memory

Every item is understood by meaning and cross-linked into a single brain — so the email, the slide, and the photo about the same project know they belong together.

3

Ask anything

Ask in plain language. Neostriatum pulls the answer across every surface at once — with the real source and date attached, not invented text.

Why it's different

Every other tool makes you move in. Neostriatum reads what's already yours.

Note apps only know what you typed into them. Enterprise search only sees your company's tools. Neostriatum is personal, cross-vendor, and zero-migration.
