What our research says

AudioBriefly

The good idea here is the delivery route: no app to install, no file to upload — you forward the voice note inside WhatsApp and the transcript comes back where the message was. Minutes-based plans are easy to reason about, and the free tier is enough to test the transcription quality. The weakness is transparency: prices only appear inside Paddle at checkout, and there is no API, so this stays a personal-use tool.

Pros

  • Works inside WhatsApp with no app install or file upload step
  • Web app accepts uploaded audio and MP4 video for non-WhatsApp material
  • Plans metered in plain minutes per month rather than opaque credits
  • Free tier of ten minutes a month needs no card, and the interface covers English, Italian and Spanish

Cons

  • No price is visible anywhere on the site — Paddle renders it only at checkout
  • No API and no bulk upload, so it does not scale past personal use
  • Free tier caps WhatsApp usage at three voice messages a month
  • Run by a single Italian sole trader, with the support surface that implies

AudioPen

The narrow focus is the point: AudioPen does one job, turning messy speech into text someone else can read, and does it across every device on a single account. The catch is the pass-based pricing, which asks for a year up front instead of letting you try a month.

Pros

  • Rewrite intensity is adjustable rather than take-it-or-leave-it
  • Custom writing styles and multi-note merging on paid passes
  • One licence spans web, mobile, Mac, Windows and Chrome
  • Zapier and webhook hooks for pushing notes into other tools

Cons

  • No monthly plan; the entry commitment is a multi-month pass
  • No documented public API, only Zapier and webhooks
  • Run by a very small operation, with little published about the company
