Show HN: Heynds – Write Faster – AI Voice and Writing Assistant (Mac/Windows)

Hey everyone,

I'm excited to share Heynds, a new desktop app for macOS and Windows (Linux coming soon!) that combines voice dictation with a powerful AI writing assistant to significantly boost your productivity.

First and foremost, I know that many solutions like this already exist, but I needed my own, something faster than all the others, that both integrates speech-to-text and a writing assistant in an all-in-one app.

The core idea is to let you work much faster by: * Voice-to-Text: Speak naturally, and Heynds transcribes your words into perfectly formatted text in real-time. Think of it as dictating emails, reports, or social media posts at 3x the speed of typing (based on studies). * Intelligent AI Writing Assistant: Instantly reformat text, polish your prose, refine messages, summarize content, and generate ideas directly from your voice or typed input. It's designed to help you overcome writer's block and ensure your communication is always clear and impactful. * Universal Compatibility: Heynds works across virtually any application on your desktop – from Slack and Notion to Gmail and even code editors.

For the AI capabilities, we leverage the *Gemini Flash model* and for speech-to-text, the Groq Whisper Large V3 Turbo model. For our "Eternal" lifetime plan, users can even connect their own API keys for full control and transparency over their usage costs.

I'd love for you to try it out! You can test it directly in your browser without any signup or download, or grab the desktop app for Mac or Windows.

Looking forward to your thoughts and feedback!
