SecondBrain vs Voicenotes

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.

Voicenotes records online and in-person meetings and turns them into transcripts, notes, summaries, action items, and next steps. It works with meeting apps without a bot joining the call, and users can ask AI questions about information in their conversations. Transcription supports 100+ languages. The free Basic plan costs nothing and includes 100 weekly transcription minutes, 30-day history, and unlimited recordings. Pro is $9 a month, with unlimited recordings, transcription minutes, history, audio imports, and storage, plus advanced integrations. Enterprise is $24 a month and adds SSO and SCIM, consent management, admin sharing controls, custom CRM and dialer integrations, and a dedicated success manager with priority support SLAs. Voicenotes lists web, Windows, macOS, iOS, and Android availability, as well as a Chrome extension. Integrations include Glean, Zoom, Google Meet, Microsoft Teams, Slack Huddle, MCP, Zapier, webhooks, Readwise, Notion, Obsidian, Todoist, and Things 3. The company says it encrypts data, is SOC 2 Type II certified and GDPR compliant, and does not use recordings or transcripts to train AI models.
