Our verdict on SecondBrain

SecondBrain is an AI note-taking assistant for people who prefer speaking over typing. It records and transcribes voice, turns voice and text into structured notes and summaries, files content into folders, and lets users ask questions across saved notes. It also supports full-text search, calendar events, reminders, a connected-note brain graph, and Markdown export. With web, iOS, and Android apps, it fits individuals who want one place to capture thoughts and turn them into organized personal knowledge.

Its standout feature is the connection between capture and follow-up. A spoken thought can become a saved note, a structured summary, a calendar event, or a reminder, while later questions can draw across the note collection. The brain graph adds a visual layer for connected ideas. MCP connections extend that memory layer to Claude, ChatGPT, Gemini, Cursor, and Claude Code, while iPhone Calendar and Apple Reminders connect captured actions with familiar mobile tools. This makes SecondBrain more than a transcription utility, particularly for users who want voice input and AI-assisted retrieval in the same workflow.

The product has a free tier, with SecondBrain Pro and SecondBrain Pro Yearly plans offering unlimited notes, unlimited AI capture and answers, and an AI assistant connector. That plan structure suits users who want to begin with basic capture and expand into higher-volume AI workflows. SecondBrain is a strong fit for personal knowledge capture across devices, especially when voice input and assistant connections matter. Choose another tool if your priority is an open-source note system, a primarily typed workflow, or a narrower app focused only on transcription rather than notes, reminders, search, and connected AI access.
