post-melt processing

Templates by persona. Streamed live. Zero clicks.

Auto-fires the instant your mic cools. No 'go' button, no second-guessing - speak, stop, and polished text streams in token by token. Pick a persona, pick a tone, or bring your own custom prompt.

What is an AI preset? The simple version.

When you dictate, you get your words exactly as you said them - including the "um"s, run-on sentences, and half-finished thoughts. A preset is a one-click instruction that tells Voxmelt's built-in AI what to turn that raw text into. You never write a prompt; you just pick from a menu.

Speak naturally

Press the hotkey and talk like you would to a person. Rambling is fine - that is the whole point.

Pick a preset

Say what you want the text to become: a polite email, a bullet-point summary, a bug report, a tidy paragraph. One click.

Get finished text

The AI on your own PC rewrites it instantly and copies it to your clipboard. Paste it anywhere. Nothing was uploaded.

Presets are grouped by persona (who the text is for - a writer, a developer, a translator) and each persona offers several tones(how it should sound - formal, casual, concise). Try them live in the playground below, no install needed. And if the menu doesn't have what you need, write your own custom prompt once and save it as a preset.
