Ideas show up at bad times. Then they are gone. Just say it out loud. SecondBrain keeps it for you. Later that day: ask in your own words. Your idea comes right back. SecondBrain Pro. Search it on the App Store.

The video shows a spoken note in Quick Capture and a later question in AI Chat. Search by meaning, as shown, needs Premium and your own backend.

A place for the things you want to remember

Catch the idea

Record a thought on your iPhone or Apple Watch. Or type a note when speaking is inconvenient.

Find the decision

Search saved memories by text, tags or dates. Use AI chat to ask about your memories when a supported AI provider is available.

Keep your context

Collect learnings, tasks and decisions over time. Choose iCloud to keep memories available across your devices.

Try the everyday workflow first

  1. Capture one thought by voice or text.
  2. Save it with a useful tag.
  3. Find it again in Recall. On supported devices, try asking AI Chat about it.

Voice capture, search and iCloud sync are included in Free. No SecondBrain account is required. Apple speech recognition may use Apple's servers; read how processing differs by feature.

Your memories, your storage choice

On this device

Choose Local Only to store memories on your device. On-device AI processes them locally on supported hardware.

In your iCloud

Sync with your personal Apple iCloud account. iCloud sync is free in every tier.

Compare storage and data flows

Bring your memories into your AI workflow

Optional for power users: Premium adds a connection to your own Cloudflare backend and MCP integration. Search memories by meaning and connect compatible tools such as Claude Code or Cursor.

This takes setup: your own Cloudflare account, a deployed backend, an API key and an MCP client. Cloudflare usage may cost extra. Memories and selected AI context are transmitted to your configured infrastructure.
