AI prompt
rewriter for Claude,
ChatGPT & more.

Wellphrase is a Chrome extension and AI prompt rewriter for ChatGPT, Claude, Gemini, Copilot, and Perplexity. It rewrites your prompt the moment before you send it, so a messy draft turns into something clearer, tighter, and easier for the model to follow.

01 / Features

Six features. One keystroke each.
Zero prompt libraries to maintain.

The core rewrite starts free. Studio unlocks the heavier drafting tools.

CoreFree
01

One-click rewrite

A quiet floating button appears next to your input. Click it. Your sentence gets re-edited in place — tighter verbs, clearer ask, no fluff.

StylesStudio
02

Style presets

Switch the rewrite voice before you send: concise, technical, warm, analytical, plain-English. Studio keeps those advanced presets one click away.

TemplatesStudio
03

Prompt templates

A small shelf of starting points for common tasks — code review, summary, interview script, critique. Insert, fill in, send.

ContextStudio
04

Attach page context

Pull the current tab's text into your prompt with one click. Useful when you're asking about an article, doc, or ticket open next to you.

03 / How it works

Three motions.
No new tabs to learn.

i. 01

Install the extension.

Free on the Chrome Web Store. Two clicks. No account needed — the free tier works the moment it loads.

ii. 02

Type like you usually do.

Open Claude, ChatGPT, Gemini, Copilot, or Perplexity. Write the messy, rushed version of what you actually want. A small Wellphrase button appears beside the input.

iii. 03

Click. Ship. Repeat.

Your prompt is rewritten in place — you can edit it further or send as-is. Every rewrite lands in your local history for next time.

// beforeyou · draft
can u look at this and tell me whats wrong w/ it also make it shorter pls
// afterwellphrase
Review the text below. Identify structural weaknesses (argument flow, unsupported claims, redundancy), then rewrite it at roughly 60% of the original length while preserving intent.
04 / FAQ

Questions we've actually
been asked.

Is my prompt data sent anywhere? +

Your prompt is sent to the Wellphrase rewriting API for the duration of the rewrite, then discarded. Nothing is stored server-side beyond what's needed to bill Studio subscriptions. Your rewrite history lives locally in your browser — never on our servers.

Who actually processes my prompt? +

Your prompt travels over TLS to our API, which routes it to a vetted third-party language-model provider that performs the rewrite. The result comes back, the request is discarded — nothing is logged on our side beyond what Stripe needs for billing. Named processors are listed in our privacy policy (and available on request).

Which sites does it work on? +

Claude (claude.ai), ChatGPT (chatgpt.com), Gemini (gemini.google.com), Copilot (copilot.microsoft.com), and Perplexity (perplexity.ai). If you'd like support for another site, write to us — we add them based on demand.

Do I need an account to use the free tier? +

No. Install the extension and start using it immediately. You only sign in when you upgrade to Studio.

What's the difference between Free and Studio? +

Free gives you 10 rewrites per day in Auto mode on all five supported sites — resets at midnight UTC. Studio removes the daily cap and unlocks all 11 style presets, prompt templates, page context, visible history, light/dark themes, three variants per rewrite, and priority model routing.

Is there a free trial for Studio? +

Yes — 7 days, no charge. We hold your card via Stripe but nothing gets billed until day 7. Cancel from inside the extension any time before then and you pay $0. No tricks, no forms, no hold music.

What happens when I hit 10 rewrites on Free? +

The FAB shows a small "limit reached" card with a countdown to midnight UTC and a Start-trial button. Your history and settings stay intact — the counter just pauses rewrites for the rest of the day.

Can I cancel Studio anytime? +

Yes — one click in the extension's Manage Subscription panel. If you cancel during the 7-day trial you're charged $0. After that, billing stops at the end of the current month and you keep Studio features until then.

Does it work with my company's SSO / enterprise ChatGPT? +

If your team uses chatgpt.com or claude.ai through standard logins, yes. For private model deployments or white-labelled interfaces, get in touch — we handle those case by case.

Firefox, Safari, Edge? +

Chrome and Chromium-based browsers (Edge, Brave, Arc) today. Firefox support is on the roadmap. Safari is further out — Apple's extension pipeline is a separate build.
