Voice typing in
ChatGPT.
The best prompts are specific, and specific means long, and long means typing. Dictate your prompts instead: context, constraints, examples, all at talking speed. A better prompt in a tenth of the effort.
Three steps, once
1. Install.
Download Fastspoken and follow the four-step setup. No account needed for the free plan.
2. Open ChatGPT.
Put the cursor where words should go, exactly like you were about to type.
3. Tap and talk.
Tap the bubble, speak like a person. Whole sentences land at the cursor about two seconds after each breath.
Prompting rewards detail. When talking is free, you stop abbreviating your intent, and the answers get better.
Private in ChatGPT, by architecture.
Fastspoken works through Android's keyboard layer, so ChatGPT just receives typed text, exactly as if you had used the keyboard. On the free plan your speech becomes text on the phone itself: offline, no account, and your words never touch a server. See the whole machine.
No server in the loop on the free plan.
Questions about ChatGPT
Why dictate prompts instead of using ChatGPT's voice mode?
Voice mode is a conversation with the AI in the app. Fastspoken makes your words into editable TEXT you control: review the prompt, tweak a word, then send. It also works identically in every other AI app.
Does it work in other AI apps?
Yes: Claude, Gemini, Perplexity, Copilot, anything with a text field. Fastspoken is a keyboard, so every prompt box is fair game.
