Frequently asked comparison questions

Why choose OneMira C1 over Plaud Note Pro for meetings?

While Plaud Note Pro offers an OLED screen and wearable card design, it relies on Plaud Cloud for transcription and limits monthly minutes unless you pay for Pro/Unlimited subscriptions. OneMira C1 delivers real-time local transcription on your computer, outputs Google Native OKF Markdown and Wiki memory, and provides built-in CLI and MCP integration with zero monthly fees.

Does Plaud Note Pro require a subscription?

Plaud Note Pro includes the free Starter plan (300 transcription minutes/month). Higher usage requires paid Pro ($99.99/year for 1,200 min/month) or Unlimited ($239.99/year) plans. OneMira C1 recording and local transcription require no subscription, and local transcription is completely unmetered.

How do privacy and audio storage compare on Plaud Note Pro?

OneMira C1 deletes encrypted audio slices immediately after your local computer transcribes them, leaving no durable audio archive. Plaud Note Pro syncs recordings to Plaud Cloud for transcription and AI summary generation.
