Goodnotes vs SecondBrain

Goodnotes is a note-taking app from Goodnotes, a company founded in 2011 and based in London. It runs on Android, iOS, macOS, web, and Windows, with offline access, note sharing, and real-time collaboration. Listed integrations include Google Calendar, Google Drive, ChatGPT, Claude, Microsoft Outlook, and Apple Calendar. The Free plan costs nothing and includes three notebooks, three text documents, three whiteboards, three folders, 100 MB of storage, and a 5 MB import limit. Essential costs $11.99 a year and includes 5 GB of storage and unlimited files, with a 7-day free trial. Pro costs $35.99 a year and includes unlimited files, also with a 7-day trial. Teams costs $120 a year and adds collaboration, SAML SSO, domain control, consolidated billing, and user and admin management. AI Pass is a $9.99 a month add-on with approximately 6,300 additional AI credits per month; availability varies by region and eligible plan. Enterprise and Special Edition have no listed prices.

SecondBrain turns spoken thoughts, typed notes and content shared from other apps into organized notes, calendar events and reminders. Its AI transcribes, titles and files notes into a folder tree that builds as material is added. Mentioning a date can create an event and reminder, and the app provides a daily morning briefing. Full-text search and an interactive 3D graph help users find notes and explore connections. A shared-memory connector using MCP supports assistants including Claude, ChatGPT, Gemini, Cursor and Claude Code. The connector requires Pro, and connecting ChatGPT also requires Developer mode, which the maker says is available on Plus or above. The maker says notes and calendar events are stored in an EU-hosted Supabase PostgreSQL database with per-account Row-Level Security; voice and text go through Google Gemini's paid API tier, which it says does not train on content. The free plan has limited notes. Pro is $8.99 a month or $34.99 a year; the App Store also lists a second yearly price of 44.99 USD.
