6 AI models. 99 languages. Advanced hallucination removal.

Our transcription pipeline uses a 6-stage process to deliver accurate results: voice activity detection, model inference, hallucination stripping, dictionary injection, text shortcut expansion, and AI grammar polish.

  • 6 Whisper models from Tiny to Large — choose speed or accuracy
  • AI grammar polish — on-device AI corrects punctuation, capitalization, and grammar
  • 99 languages with automatic detection or manual selection
  • Hallucination stripping removes phantom text from silent segments
  • Custom dictionary injection for specialized vocabulary (medical, legal, technical)
  • Text shortcuts — speak or type trigger abbreviations that expand to full text with dynamic macros

Text Shortcuts

Say less, type more

Create trigger abbreviations that expand into full text blocks — activated by voice or keyboard. Just say "slash soap" during dictation and get a complete SOAP note template, or type the trigger directly. Built-in macros insert today's date, time, and clipboard contents automatically.

  • Voice or keyboard triggers — say "slash sig" or type /sig to expand full text blocks instantly
  • Dynamic macros — %date%, %time%, %day%, %clipboard% resolve at expansion time
  • Unlimited snippets — create as many shortcuts as you need, organized by category
  • Import & export — share snippet libraries as JSON, or import from colleagues
  • Built-in text shortcuts — no extra subscription needed
