BeforePrompt for Chrome

A prompt coach that stays out of the way.

Write in the AI tool you already use. BeforePrompt checks the draft beside the prompt box, shows the problem in plain language, and lets you decide whether to rewrite it.

The Chrome Web Store listing is being prepared. Create an account now and this button can point to the official listing as soon as it is approved.

What it does

Small checks that prevent long reruns.

Reads the active draft

Only the text in the prompt editor is analyzed. It does not scan unrelated browsing.

Flags sensitive details

Local checks look for common secrets and personally identifiable information.

Finds missing context

Vague audience, unclear format, and missing success criteria are called out before send.

Rewrites on request

Improve, shorten, structure, clarify, or surface the questions you need to answer.

Privacy by action

Local first. Cloud only when the task needs it.

The first pass happens on your device. A prompt is sent to the BeforePrompt service only after you choose a cloud rewrite action. Conversation context is sent only after you review and approve it. Prompt history starts off.

Local rule engine

Quality and sensitive-data checks run in the browser.

Deliberate cloud actions

A rewrite leaves the browser only after a click.

Opt-in history

Saving original and improved prompts is disabled by default.

Supported sites

Four prompt boxes. One familiar check.

Ready when the listing is.

The website uses one configurable Chrome Web Store URL. No redesign will be needed after approval—add the official listing URL and every install button updates.
