In their own words
HyNote
HyNote turns meetings and other material—including audio, PDFs, videos, images, websites, and text—into searchable notes. It transcribes in more than 50 languages, identifies speakers, and offers live translation. The service can create summaries, key points, action items, and meeting notes, with more than 30 professional templates. Study features include flashcards, quizzes, and study plans; publishing tools can produce blog posts, podcasts, slides, and infographics. HyNote exports to Google Docs and Notion, syncs with Google and Apple Calendar, and offers Google Calendar reminders and a way to join Google Meet and start recording from its Calendar page. It is available on web, macOS, iOS, Android, and as a Chrome extension. The free plan includes recording, transcription, uploads, and calendar integration, with sessions capped at 120 minutes. Pro costs $6.66 a month, billed annually, and a 7-day trial is listed. Mobile use requires an active internet connection; the Mac app requires macOS 14 or later.
SecondBrain
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.
