Features

Everything you need to remember more

A focused system for capture, retrieval, and AI-powered connections — without the clutter of a generic notes app.

Search everything

Ask in plain language. Memory-OS finds notes, links, meetings, and highlights across months of context.

Capture anywhere

Browser extension, mobile, and API. Drop thoughts in the moment — organize later, or never.

Knowledge graph

See how ideas link together. Surface clusters you didn’t know you were building.

AI connections

Automatic “this relates to…” suggestions that pull from your own history — not the open web.

Memory growth

Track how your second brain expands. Spot active topics and quiet gaps over time.

Smart collections

Work, Learning, Ideas, Personal — auto-sorted when possible, fully controllable when you care.

How it works

Three steps to a quieter mind

Designed for people who capture more than they can organize by hand.

Capture freely

Clip pages, dump meeting notes, save voice memos. Don’t worry about folders in the moment.

Ask anything later

Search with questions, not keywords. Memory-OS ranks what matters from your private corpus.

Let AI link the rest

Related notes surface automatically so old ideas keep paying rent in new projects.

Pricing

Start free. Scale when it sticks.

No credit card for the free tier. Upgrade when capture volume and AI features earn it.
