Choose your AI engine
Hearsy supports three LLM providers for AI enhancement, each with different strengths. You bring your own API key for cloud providers, or use the bundled local model for fully private enhancement.
Switch between providers anytime in settings. Your API keys are stored securely in macOS Keychain — never transmitted to Hearsy's servers. The local Qwen model requires no API key and no internet connection.
All three providers work with every enhancement template and custom prompt. The difference is in quality, speed, and privacy tradeoffs.

How AI enhancement works
Enhancement is a single extra step in the dictation pipeline — completely optional.
Raw transcription
Your speech is transcribed locally by Parakeet or Whisper. This step always happens on-device.
LLM processing
The raw text is sent to your selected LLM with the active template or custom prompt. Local Qwen stays on-device; Claude/OpenAI use their APIs.
Enhanced text pasted
The refined text is placed on your clipboard and auto-pasted to the active app. The entire flow takes 1-3 seconds.
Rewrite this as a professional email. Keep the key points but make it concise, polite, and well-structured. Add a greeting and sign-off.
hey so the deadline is moved to friday and we need the designs by wednesday can you make that work
Hi team, The project deadline has been moved to Friday. Could you have the designs ready by Wednesday? Let me know if that timeline works. Best regards
Write your own prompts
Beyond the built-in templates, you can create custom prompts that transform your dictation in any way you need. Write a prompt once, and it's applied to every dictation automatically.
Use cases are limitless — rewrite as professional emails, extract action items from meeting notes, translate to another language, convert to bullet points, generate code comments, or match your company's writing style guide.
Custom prompts work with all three LLM providers. Save multiple prompts and switch between them based on what you're working on.
