Word of mouth

Creator notes that more than 50% of users end up using it for meeting notes, suggesting organic adoption through daily workflows

Growth Levers

  • Double down on the meeting notes use case since 50%+ of users already use it for this purpose
  • Build direct audio tapping for Zoom/Teams calls on macOS to reduce friction for meeting transcription
  • Add a meeting bot feature that can join calls directly (as suggested by a commenter)
  • Expand journaling prompts library — gratitude journaling, idea capture, anxiety management templates
  • Market to productivity and journaling communities on Apple-focused forums and subreddits
  • Leverage the privacy angle of local Whisper transcription vs cloud-based competitors

First Customer Strategy

The creator built the product to solve their own problem — tried various note-taking apps but nothing stuck like Apple Notes, and found that talking about ideas was the second-best method for thought clarity after writing by hand. By combining voice recording, local Whisper transcription, and LLM rewriting, they created a friction-reducing tool. Post-launch, users organically discovered the meeting notes use case.

Pricing Insight

No pricing details mentioned in the thread. The product integrates with Apple Notes and uses local Whisper for transcription, suggesting a one-time purchase or subscription model to cover LLM API costs.

New Market Opportunities

  • Meeting transcription and summarization Asked about Zoom call transcription; creator confirmed many users already use it for this and is working on direct audio tapping
  • Meeting bot integration Suggested letting the app join meetings directly rather than just listening to system audio
  • Mental health and wellness journaling Creator built in prompts for journaling based on expert recommendations — gratitude journaling, anxiety management, life events tracking

Key Takeaways

  • • Users often discover use cases the creator did not prioritize — meeting notes became the dominant use case despite being built as a journaling tool
  • • Building on existing ecosystems (Apple Notes) reduces adoption friction because users stay in their familiar workflows
  • • Local transcription (Whisper) is a privacy differentiator in the voice-to-text space where competitors use cloud APIs
  • • Combining existing technologies in a novel way (voice + transcription + LLM rewriting) can create a compelling product without breakthrough tech
  • • The gap between 'it works if you know how' and 'it works seamlessly' is where product-market fit deepens (e.g., Zoom audio tapping)
  • • Solving your own daily friction point (journaling, note-taking) is a reliable path to building something others want too
