How to choose an AI writer for marketing copy, with 5 examples
On this page5
An AI writer will not fix weak copy. It writes faster what you already know how to say. The real difference between tools shows only after the first draft.
This guide is for business owners and marketers who write ads, product pages and emails, in Arabic or English. The goal is one tool that fits your work, not five subscriptions.
If you only want a starting point, here are three, by the kind of copy you write most. The rest of the guide shows how to check them against your own work.
Copy.ai: many short pieces
Templates for ads, social posts, emails and product descriptions.
Rytr: quick short copy
A simple editor with many tones and languages, for someone starting out.
Jasper: one voice for a team
Brand voice settings and long drafts, for teams that publish a lot.
The usual mistake: choosing by the demo
Every tool looks good on a generic prompt such as “write a caption for a coffee shop”. That test tells you nothing about your product, your offer or your customer.
The second mistake is counting features: how many templates, languages or words a month. Those lists change often. What stays is how much editing a draft needs before you would publish it.
How I would choose, step by step
1. List the copy you write every week
Write down the real jobs: ad variations, product descriptions, emails, landing pages, blog articles. Short copy and long articles need different tools. A store that writes product pages all day needs a different tool from a consultant who publishes one long article a month.
2. Test in the language you sell in
Many tools write Arabic that reads like translated English. Ask for an ad in Arabic and read it aloud, the way your customer would hear it.
- Does it sound like your customers in Saudi Arabia or Egypt, or like a textbook?
- Does it keep brand and product names in Latin letters?
- Does it write numbers in Western digits, if that is your style?
- Does the text still read well right to left inside the ad preview on a phone?
3. Give every tool the same real brief
Use one product, one offer, one audience, and three phrases your customers actually say. Run that brief in each tool and put the drafts side by side.
Then count the edits each draft needs before you would publish it. The tool with the fewest edits is the one for you, not the one with the longest draft.
4. Check that it keeps your voice and your facts
Look for a place to save your tone, the words you never use and the facts about your product, once. Without it, you paste the same instructions into every prompt. Check also that the tool keeps a history of past drafts, so a draft you liked does not get lost.
5. Check every claim it adds
AI writers invent numbers, reviews and features with full confidence. Check any sentence with a figure, a guarantee or a comparison against your own data before it goes live. A made-up number in an ad costs you more trust than a plain sentence.
6. Compare it with a general assistant first
Run the same brief in a general assistant you already use, such as ChatGPT, Claude or Gemini. Pay for a dedicated writer only if it saves you real editing time. That usually comes from a saved brand voice, team seats, templates you use every week, or search data for articles.
7. Work out what your real volume costs
Tools bill by words, by credits or by seat, and plans change often. Price one month of your actual volume, not the entry plan. Make sure the tool shows what each draft used, so the bill holds no surprises.
An example from my own work
For Legend AIM, I wrote six video ad scripts for the content team. Each one showed what the device does, with real users and what they say about it.
That material came from the store and its customers, not from a tool. An AI writer can shape a script like that and suggest an opening line. It cannot supply the customer’s words, so collect those yourself and let the tool help with the shape.
Five tools, by what they are built for
These are examples, not a ranking. Each description says what the tool was built to do. Features and plans change, so run step 3 on the current version before you pay.
Copy.ai
Copy.ai started as a template tool for short marketing copy: ads, social posts, emails, website copy and product descriptions. It also has a long-form assistant for blog drafts.
It fits a team that needs many short variations every week, such as ad tests. In your trial, check the Arabic output and whether past drafts are saved.
Jasper
Jasper, first known as Jarvis, is built for marketing teams. It offers templates for campaigns, long-form drafts, and guided workflows that take you from an outline to a full article.
It fits a team where several people must write in one brand voice. Before you commit, learn how it counts usage, because credit-based billing can be hard to track.
Writesonic
Writesonic pairs a long-form editor with templates for blog posts, SEO, emails, ads and website copy. You can set the tone of voice on some templates, not all.
It fits someone who writes search content as well as short copy. Test tone control on the templates you will use. If you write about technical topics, test one technical article too.
Rytr
Rytr is a simple editor for short copy, with many tones of voice and languages and a built-in plagiarism check. It is made for short pieces: you build a long article section by section from its templates.
It fits someone starting out who writes captions, short ads and product lines. Try the same ad in each tone you use and read the Arabic version aloud.
Scalenut
Scalenut is built for SEO articles. It covers keyword research, grouping related topics into clusters, reading the search results for your niche, and reports on content you already have. A Chrome extension brings its templates into sites such as Gmail and LinkedIn.
It fits someone who publishes articles to rank in Google, less so someone who writes ads. Before you pay, check whether its keyword data covers your market and your language.
Checklist before you pay
- The jobs you need the tool for, written down.
- One real brief, run in every tool on your list.
- The Arabic draft read aloud by someone who sells in your market.
- Your tone, banned words and product facts saved once in the tool.
- A history of past drafts.
- One month of your real volume priced on the current plan.
- A person who checks every number and claim before anything goes live.
If you want a second opinion on your copy, send me one ad you are running and what it brought last month. I will tell you what I would change first, with or without a tool.
