AI Tool to Review Copy: Check Every Draft Before It Ships
An AI tool to review copy reads a draft against fixed rules and points to the exact line that needs work: a claim with no proof, a phrase that reads machine-written, a missing step in the structure, two calls to action pulling in different directions. The useful ones give you a verdict (fix first, verify, or ready) and the replacement, not a grammar score.
If you write with Claude or ChatGPT, you already have a fast first draft. What you don’t have is a second reader who checks it the same way every time.
Why doesn’t asking the AI to “review this” work?
Ask the model that wrote the draft to review it and it mostly agrees with itself. It tightens a few sentences, swaps some words and calls it done. Ask again tomorrow and you get different notes, because there’s no fixed list it checks against.
The problems that cost sales are the ones it doesn’t look for:
- A number or result with nothing next to it to back it up.
- “Free” with no condition, or a deadline that isn’t real.
- The phrases readers have learned to skim: “in today’s fast-paced world”, “unlock”, “game-changer”.
- A page that asks for a purchase and a newsletter signup in the same breath.
- A sales argument that skips a step, so the price arrives before the reader believes anything.
A grammar checker won’t catch these either. It reads sentences, not arguments.
What should a copy review tool check?
| Check | What it catches | Example of a fix |
|---|---|---|
| Structure | Missing or weak steps in the framework the draft follows | Add the “how it works” step before the offer |
| Persuasion | Claims without proof, competing calls to action, unanswered objections | Keep one action per email |
| Offer | What the buyer gets, the price and the risk reversal, stated or missing | Say what happens after the trial |
| Claims | Lines that need proof or get ads rejected, with stricter rules for health and money | Put the source in the same line as the number |
| Voice | Phrases and rhythm that read machine-written | Cut the tier 1 tells, vary sentence length |
| Format | Field limits for ads, subject and preview for emails, headline and hook rules | Trim the ad headline to the network’s limit |
The guide to editing AI drafts walks through the same passes by hand. A tool runs all of them on every draft, including the ones you’d skip when you’re in a hurry.
How does the review tool in Copix work?
Copix plugs into the AI you already write with (Claude, ChatGPT, Cursor or Claude Code) as an MCP server. When your draft is ready, your AI calls review with the draft and what it is: an ad, a landing page, an email, a blog post, a hook and so on.
Copix runs every check that asset needs in one pass and sends back:
- A verdict: fix first, verify, or ready.
- A scorecard: each check marked pass, verify or fix.
- The top fixes: up to ten, each with the exact text and what to change.
“Verify” means only you can answer it: is that testimonial real, is that deadline real. Copix never fills in proof you didn’t give it. Your AI fixes what’s marked fix, asks you about what’s marked verify, and shows you the clean version.
The checks are rules, not another model’s opinion, so the same draft gets the same review every time. And because review reads your saved brief (your offer, buyer, voice and proof), it knows which claims you can back. The setup guide shows how to connect Copix, and Claude for copywriting shows the full write, review and fix loop.
What does a review look like on a real draft?
We ran this post through review before publishing it. It came back “fix first”, and the notes were specific:
- The line about the free trial was marked verify: “free” needs its condition in the same line. That’s why the pricing section below says you add a card and what happens after 14 days.
- The draft had no reason why next to the plan list, so we added the one that matters: Basic covers drafts, Complete measures what’s live.
- Two warnings about a “deadline” were word matches on this post’s own examples. We read them and dropped them, which is what the verify step is for.
That’s the loop: the tool finds the line, you or your AI decide, and the draft that ships has been read against the same rules as the last one.
What does the review tool cost?
review is in both plans and unlimited. Pick by what you need checked: Basic covers drafts before they ship; Complete also measures the page or ad once it’s live, which is where the engines spend credits.
- Copix Basic, $9 a month ($90 a year):
write,reviewand your saved brief. Run every draft through it as often as you like. - Copix Complete, $29 a month ($290 a year): everything in Basic plus the four engines (SEO, GEO, Conversion, Ads), with 1,500 credits every month.
Your first plan starts with a 14-day free trial: you add a card at checkout and pay nothing for 14 days, then the monthly price unless you cancel from your account.

FAQ
Does Copix rewrite my copy?
Your AI does the rewriting. Copix gives it the method and the review, with the exact line and the fix, and the writing stays in your chat.
Which kinds of copy can it review?
Ads, landing pages, sales pages, product pages, VSL scripts, emails and sequences, social posts, threads, scripts, blog posts, bios, stories, offers, headlines and hooks.
Will it make my copy sound less like AI?
The voice check flags the phrases and rhythm that read machine-written, line by line. Make AI writing sound human lists the most common ones.
Is the review the same every time?
Yes. The checks are rules, so the same draft gets the same findings. Only the fixes your AI writes can vary.
Is my draft stored?
Copix keeps the size and a digest of each call for the usage log, never the draft.
