## What is Second Brain?

Speak or type one messy thought. Second Brain separates every intention, creates the right Apple Reminder, Calendar event, or Markdown update, and shows exactly what changed.

Your tasks stay in Apple Reminders, your dates stay in Apple Calendar, and your knowledge stays in ordinary Markdown files you control.

VOICE TO ACTION
• Speak or type when one thought contains several intentions
• Attach an existing image or take a photo without leaving the capture
• Turn things you need to do into Apple Reminders
• Put meetings, deliveries, and passive dates into Apple Calendar
• Create, append to, or update the right Markdown page
• Keep dates and times exactly as you expressed them

SEE AND CONTROL EVERY CHANGE
Each capture keeps your words and a receipt for every result. Review destinations, confirm pending events, retry failures, repair exact duplicates, or undo supported changes.

YOUR TOOLS, NOT ANOTHER SILO
• Tasks live in Apple Reminders
• Events live in Apple Calendar
• Context stays in ordinary Markdown files
• Use the recommended iCloud Drive folder, another Files folder, or an Obsidian vault
• Capture from Siri, Shortcuts, widgets, Control Center, the share sheet, or the Action Button

KNOWLEDGE WITH SOURCES
Ask questions about your pages and inspect linked sources. Search in the app, Siri, or on-device Spotlight. Projects keep notes, pages, reminders, events, and recent activity together.

MANAGED INTELLIGENCE
Managed Intelligence is an optional monthly or annual App Store subscription for hosted OpenAI processing. The secure service verifies access and limits, stores no request bodies, and deletes temporary results after acknowledgement or within 24 hours.

EXTERNAL AI PROVIDER CONNECTIONS
Settings > AI & Providers can connect an existing Anthropic or OpenAI developer account as an external service. Second Brain does not sell provider access or include provider sign-up, pricing, or purchase links. The credential stays in Apple Keychain, and requests go directly to the selected provider under that provider's terms.

PRIVATE BY DESIGN
Before any personal data is sent to an AI service, Second Brain names the recipients and data categories and asks for permission. Choose Use Without AI to keep all AI transmission disabled while local capture, notes, reminders, events, and search remain available. Managed requests go to Second Brain's Cloudflare-hosted service and then OpenAI. Personal-key text requests go directly to OpenAI or Anthropic. Permission can be reviewed or withdrawn in Settings > Privacy & AI.

Voice can be transcribed fully on device with Apple Speech, so audio never uploads, or through an optional permission-gated online route. When Online transcription is selected, recordings go to OpenAI directly or through the managed Cloudflare route. Failed or cancelled online uploads preserve the local recording for retry. Photos stay local unless the user includes them in an authorized AI request. There is no Second Brain login, advertising, or tracking. Firebase Analytics and Crashlytics receive content-free product or diagnostic data, never captures, transcripts, audio, chat, files, titles, keys, or model content. The public What Gets Sent view and content-free privacy ledger show the applicable routes and transfers.

SUBSCRIPTION TERMS
Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. Manage or cancel subscriptions in your Apple Account settings. Any trial converts to the selected paid plan unless canceled before the trial ends.

## Version history (last 5 releases)

### 1.6 — 2026-08-27

Second Brain 1.6 keeps work visible and gives voice capture a private local route:

• Follow captures, searches, edits, and purchases through a live status orb that expands into progress, results, and recovery controls
• Choose on-device Apple Speech transcription that never uploads audio, or the existing permission-gated Online transcription
• Take a photo directly from Capture and review it with the rest of the input
• Keep recordings safe through suspension, network loss, and retryable transcription failures
• See clearer Capture, Inbox, Activity, Ask, Notes, onboarding, and Settings surfaces

### 1.5 — 2026-08-18

Second Brain 1.5 makes Managed Intelligence clearly optional:

• The Managed Intelligence screen now contains only App Store subscription and restore controls
• Continue with local capture, notes, Reminders, Calendar, and search without subscribing
• Connect an existing external AI developer account separately under Settings > AI & Providers
• Keep provider credentials in Apple Keychain on the device
• Continue to review or withdraw AI data-sharing permission independently

Capture processing and generated pages are also more reliable:

• Prevent duplicate Calendar events, Reminders, and pages when foreground and background processing overlap
• Reuse the original page or event safely when an interrupted action is retried
• Show Project, Created, Updated, and a collapsible original capture as page fields instead of repeating them in the Markdown body

### 1.4 — 2026-08-15

Second Brain 1.4 unifies projects and makes interrupted work recover cleanly:

• Create a project and its requested child pages in one correctly routed capture
• See Project created once in receipts, with created pages counted separately
• Edit a project's name, color, description, and Markdown notes in one place
• Rename a project while preserving child pages and known links
• Repair older receipts that misplaced exact duplicate pages
• Use Misc as the fallback when a note has no better project
• Keep capture, Ask, page editing, research, and voice work pending through temporary access or network failures, then resume automatically
• Preserve recordings and pending results across suspension or relaunch without creating a note from the raw request
• Review Cloudflare, OpenAI, and Anthropic routes before any personal data is sent, or choose Use Without AI
• Review or withdraw AI permission in Settings > Privacy & AI without losing local work

### 1.3 — 2026-08-01

Second Brain 1.3 makes intelligence easier to start and more reliable to use:

• Choose built-in Managed Intelligence with an App Store subscription, or connect your own Anthropic or OpenAI key
• Purchase, restore, and refresh subscription access without leaving your current workflow
• See clearer privacy information for managed and personal-key requests
• Get more actionable voice availability, transcription, retry, and setup states
• Finish capture processing within two minutes, saving any unresolved text safely in Ideas
• Keep Capture, Chat, Inbox, Pages, and background processing on one consistent intelligence path

### 1.2 — 2026-07-25

Second Brain 1.2 is a broader, more dependable workspace:

• Attach images and files, preview exactly what is sent, and use supported images with your chosen AI model
• See local images inside Markdown pages and open the original attachment
• Create and edit recurring reminders and calendar events with clearer previews
• Navigate Pages, Inbox, receipts, and privacy history with more consistent controls
• Capture reliably from voice, Siri, Shortcuts, the share sheet, Control Center, and the Action Button
• Start voice capture over AI Chat or a detail screen without losing your conversation, draft, or place
