Personal memory layer · macOS

One memory for everything you've already saved.

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

Live today across six surfaces. Apple Photos, Apple Notes, and ChatGPT history follow.

The problem

You have the information. You simply cannot find it across the places it lives.

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

How it works

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

01

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.

02

It builds one memory

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

03

Ask anything

Ask in plain language. Neostriatum returns the answer across every surface at once — with the real source and date attached, never invented text.

Why it's different

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

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

Your data

Private by default. The point is yours to keep.

  • Your data stays yours. We do not sell it, and there is no ad model.
  • We do not use your content to train anyone's models.
  • Neostriatum reads your surfaces in place. Nothing is migrated into a silo.
  • Portable and exportable. You can leave with everything.
Surfaces

Live today across six. More on the way.

The adapter architecture adds surfaces quickly — the memory grows deeper the more of your life it can read.
