Promty: Voice to AI Prompt

On-device dictation, offline

Only for Mac

Free

Mac

Promty turns messy, spoken-out-loud thoughts into clean, structured prompts for AI models — and it does the whole job on your Mac, with nothing sent to a server. Hold a hotkey, talk the way you actually think, and release. Promty transcribes your voice on-device, then uses an on-device AI model to tighten the transcript into a clear, well-structured prompt. The result lands right where you're working, ready to paste into your favourite AI tool. WHY PROMTY • Fully on-device. Transcription and prompt cleanup both run locally. Your voice and your text never leave your Mac. • Faithful, not creative. Promty never invents facts, drops your constraints, or changes your numbers, names, or dates. It removes filler and structure — nothing more. • Fast. Hold to talk, release, and your cleaned-up prompt is ready. • Works everywhere. Deliver the finished prompt to the clipboard, or paste it straight into the app you were already using. • Type or talk. Prefer to type? Enter text directly and Promty cleans that up too. HOW IT WORKS 1. Hold your chosen shortcut and speak. 2. Release. Promty transcribes on-device and compresses the transcript into a tidy prompt. 3. The prompt is delivered to your clipboard or pasted at your cursor. Promty is built for anyone who thinks faster than they type — developers, writers, researchers, and anyone who works with AI tools every day and wants their prompts to be clear and consistent without the fuss.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Faster prompt compression, and a fix so requests for code, regexes or queries are cleaned up instead of answered.
