How It Works

Three Steps.
Zero Friction.

Press a hotkey, speak, and your words appear as text — right where your cursor is. No app switching, no typing, no copy-pasting.

A sleek overlay appears wherever you are. No window switching, no interruptions.

Speak Naturally

Talk like you normally would. HeyDict transcribes your speech in real time, right as you speak.

Text Appears.

Your words are injected directly into the active text field. Any app, any window, any OS.

Built for Every Platform

Every Operating System.
