MCAFax is not a lender or a law firm. --- Verdict: a low-risk, high-use editor for any owner who writes their own copy, with a change list that makes it easy to trust. Bot reviewed: Copy Humanizer, by Massimo De Luisa, listed under Marketing in the Grok Bot Marketplace. Listing opened for this review: https://x.ai/bot/marketplace/bots/human-copywriter Reviewed from the public listing only. We did not install or run the bot, so nothing below is a test result. ## What it does Copy Humanizer edits and rewrites emails, landing pages, posts, blogs, and DMs so they read like a person wrote them. It has two modes. Editing tightens a draft you wrote while keeping your voice, and hands back a numbered list of every change and why. Rewriting rebuilds stiff, corporate, or machine-sounding copy in your voice for the channel it is headed to. Both run what it calls an anti-slop pass, both keep every fact from your source, and it builds a voice profile from writing samples you share. ## Who it's for It is for anyone who writes for their business and either hates editing or leans on AI drafts that sound like AI. For a small-business owner, that covers website copy, customer emails, and social posts, without hiring an editor. ## Strengths - Shows its work: a numbered change list with a reason for each edit, so you learn and stay in control. - Strict fact rule: the listing says it never invents a fact, name, number, price, quote, or customer, and gaps in your source stay visible. - A voice profile with a quoted example per rule, updated after what you actually ship. - It drafts and you publish. Its weekly check stays off until you turn it on. ## Limits and risks - Voice matching needs good samples. Give it little and you get generic results. - It is an editor, not a strategist, so it will not tell you what to say, only how to say it better. - Making copy sound human is not the same as making it true or compliant. You still own the claims, especially in regulated areas like finance. - The listing mentions checking what is connected but does not list which accounts it uses, so review any connection it asks for. ## Score: 9/10 Scoring rubric: four parts, each 1-10, averaged and rounded: usefulness for a small-business owner, safety guardrails, setup effort (higher means easier), and clarity of what it does and does not do. - Usefulness for a small-business owner: 8/10 - Safety guardrails: 9/10 - Setup effort: 9/10 - Clarity: 9/10 ## How it compares with MCAFax's "skills, not prompts" approach Copy Humanizer fixes how your writing sounds. MCAFax's skills-not-prompts idea is about what your AI knows: a reader loads one skill and their AI taps MCAFax's knowledge base instead of being rebuilt from scratch. An editor skill like the one below is a good example of a portable job any AI can do, and it pairs naturally with a knowledge skill: get the facts from the knowledge base, then run the copy through the editor. ## Turn this bot into a skill for any AI This is MCAFax's own write-up, in our words, of the job Copy Humanizer describes on its public listing. It is not the creator's prompt and not an official Copy Humanizer skill. Credit for the original bot goes to Massimo De Luisa. Paste it into Claude, ChatGPT, Grok, or any AI that accepts skills or custom instructions. ``` --- name: Human-sounding copy editor description: Use when I paste a draft (email, page, post, DM) and want it tighter and more natural without losing my voice, or when copy sounds stiff, corporate, or written by AI. --- ## Steps 1. If you don't have my voice yet, ask for one or two pieces of writing I like and 3 words or phrases I never want to see. Write a short voice profile with one quoted example per rule. 2. Decide the mode. If I wrote it, edit lightly and keep my voice. If it sounds machine-made or corporate, rewrite it for the channel it's going to. 3. Cut filler openers, stacked adjectives, vague hype, and repeated ideas. Use short sentences and plain words. 4. Return the finished draft first, ready to copy and paste. 5. Below it, give a numbered list of what you changed and why. ## Guardrails - Keep every fact from my source. Never add a fact, number, price, name, quote, or customer. - If something is missing, leave a visible [gap] instead of filling it in. - Never publish or send anything. I do that.
