How it works

Up and running in 30 seconds

Install once and AutoPrompt is ready in every text field, on every site.

Type your rough idea

Go to any website and type your rough prompt into a text field. It doesn't have to be perfect — that's the whole point.

Press your shortcut

Hit Ctrl+Shift+Q. AutoPrompt captures your text and sends it to the AI for instant refinement.

Review and accept

The Floating Refiner appears with a polished version. Fill in any context hints, then click Accept — the refined text lands right back in the field.

Features

Everything you need, nothing you don't

Built to stay out of your way until you need it.

The Floating Refiner

A sleek overlay appears right on the page. Review the enhanced prompt, fill placeholders, then accept with one click — injected straight back into the field. No context switching.

Smart Placeholders

When the AI detects your prompt could be more specific, it adds [Client Name] or [Deadline] style blanks. Fill them in or leave them — empty ones are removed automatically.

Context Awareness

AutoPrompt remembers up to 10 recent prompts so each refinement builds on your current session's theme. Toggle it off anytime in Settings if you want a clean slate.

Iterative Refinement

Accept an enhanced prompt, then press the shortcut again. Each pass starts from a stronger base — two or three cycles can turn a decent prompt into a precisely scoped masterpiece.

Custom System Prompt Power

Replace the built-in Prompt Architect persona with your own system prompt. Define your own refining style, domain constraints, or output format — full control for prompt engineering fanatics.

When enabled (default), hitting Accept clears your original text and puts the refined version in its place. When disabled, the refined text is appended or inserted depending on the text field.
Your quota resets at midnight UTC. You'll see a limit-reached message in the refiner. You can keep using AutoPrompt again from the next day.
