The best AI tool for copywriting depends on the job. A general assistant such as ChatGPT, Claude or Gemini handles most drafting and rewriting. A dedicated platform such as Jasper, Copy.ai, Writesonic or Anyword makes sense when a team needs brand settings, shared workflows or testing. Frase and Scalenut are built around SEO content. Grammarly suits editing.
Several of these products have changed direction in the last two years, so the names you remember may not do what you expect. Below, each tool is described as its own site presents it today, with a short note on who it fits and what to check before you pay.
What matters in an AI copywriting tool
Skip the feature lists and ask five questions.
- Does it fit how you write? A chat assistant suits one person working on drafts. A platform suits a team that needs templates, approvals and shared brand rules.
- Can you control the voice? Look for a way to save tone, terms to use and terms to avoid. Without it, you rewrite every draft to sound like you.
- What does it do beyond writing? Some tools now sell research, SEO scoring, workflows or agents. That’s useful only if you’ll use it.
- How do you review output? You stay responsible for facts, claims and tone. Pick a tool that makes editing and fact-checking easy.
- Is there a free way to try it? Test with your own brief before you commit. Plans and limits change, so read the vendor’s current page.
General AI assistants
ChatGPT
ChatGPT is OpenAI’s AI assistant. People use it for drafting, rewriting, brainstorming headlines and adjusting tone, all through a plain conversation. It’s a good first tool because there’s little to learn: describe the audience, the goal and the format, then edit what comes back. The limit is that it doesn’t know your brand unless you tell it each time or set up instructions. See chatgpt.com.
Claude
Claude is Anthropic’s AI assistant. Its site presents it as an assistant for work, and writers use it for long drafts, editing passes and rewriting in a given voice. It’s worth trying if you work with long documents and want help with structure and tone. Visit claude.com.
Gemini
Gemini is Google’s AI assistant. Google describes it as help with writing, planning and brainstorming. It’s a natural fit if your team already works in Google’s apps. See gemini.google.com.
These three overlap heavily for everyday copy. Try the same brief in each and see which draft needs the least editing. That test tells you more than any feature comparison.
Dedicated copywriting and marketing platforms
Jasper
Jasper’s site now describes AI agents for marketing, with workflows that run end to end and keep control with your team. If you remember it as a template-based copy generator, that’s no longer how it presents itself. It suits marketing teams that want brand control and campaign workflows in one place. Visit jasper.ai.
Copy.ai
Copy.ai now calls itself a go-to-market AI platform, aimed at automating repetitive sales and marketing tasks. It started as a short-form copy tool, so check whether its current workflow focus matches what you need. It fits revenue and marketing teams more than solo writers. See copy.ai.
Writesonic
Writesonic presents itself as an AI search growth platform covering generative engine optimisation and AI visibility. It’s less a pure writing tool than it used to be. Choose it if you want to track how your brand appears in AI answers as well as produce content. Visit writesonic.com.
Anyword
Anyword says it works with any AI model or application and adds A/B-tested data to the generation process. Its pitch is performance: ad, email and landing page copy shaped by data. It suits marketers who run tests and want data feeding the writing. Read the claims on its own site and judge them against your own results.
Hypotenuse AI
Hypotenuse AI describes itself as an AI-first product experience management platform for ecommerce, generating on-brand product content and catalog images. If your copywriting is mostly product descriptions across a large catalogue, it targets that job. See hypotenuse.ai.
SEO-focused content tools
Frase
Frase now describes itself as a content platform for AI search, writing and optimising content for Google and for citation by AI answers. It started as a research and brief tool. It’s built for people who plan content around search questions. Visit frase.io.
Scalenut
Scalenut combines AI-assisted SEO, content creation, keyword research and AI visibility tracking, and it also offers expert-led services. It suits teams that produce a lot of search content and want planning and writing together. See scalenut.com.
Editing and rewriting
Grammarly
Grammarly offers AI writing help that works across apps and websites. It’s the tool to pick if you already write your own copy and want help with clarity, tone and rewrites in the places you work. The older “GrammarlyGO” name has been folded into the main product. Visit grammarly.com.
Wordtune
Wordtune describes itself as an AI writer that can paraphrase, rewrite and correct grammar. It’s a light option for tightening sentences. See wordtune.com.

Choosing by role
Solo writers and freelancers
Start with one general assistant and learn it well. You get drafting, rewriting and idea generation without a team plan. Add Grammarly if editing your own text is where you lose time.
Small business owners
You write a bit of everything: product pages, emails, social posts. A general assistant plus a saved brief about your business covers most of it. Keep that brief short and specific, with who you sell to and what makes you different.
Marketing teams and agencies
Shared settings matter more here. Look at platforms like Jasper, Copy.ai or Anyword, and ask how each handles brand rules, approvals and handoff between people. A free trial with two real campaign briefs shows you quickly whether the workflow fits.
SEO and content teams
Frase and Scalenut are built around research and briefs for search. Use them to plan which questions a page must answer, then write and edit with a human voice. For the plugin side of search, see our guide to the best SEO plugins for WordPress.
Ecommerce stores
Product descriptions are repetitive, which suits AI help. Give the tool the specs and the customer’s likely questions, then check every detail against the product itself. A wrong dimension or material is worse than a plain sentence.
A simple brief you can reuse
The same structure works in every tool above. Fill in the blanks and paste it in.
- Audience: who reads this and what they already know.
- Goal: the single action you want, such as signing up or reading on.
- Format and length: a headline, a 90-word product blurb, a three-line email opener.
- Facts to use: the specifics the copy must include.
- Voice: two sentences you’ve written that sound like you.
- Avoid: phrases, claims and topics that are off limits.
Most weak AI copy traces back to a thin brief. When the output feels generic, add a fact or an example before you change tools.
Disclosure, rights and privacy
Read each vendor’s terms on how your inputs are used and who owns the output. Don’t paste customer data, unreleased financials or anything under a confidentiality agreement into a tool unless its terms and your own policies allow it. Some platforms and publishers ask you to disclose AI assistance, so check the rules where you publish.
How to get usable copy from any of them
- Write a real brief. Give the audience, the offer, the format, the length and one example of copy you like.
- Supply facts. The tool doesn’t know your product details unless you paste them in. Anything it adds on its own needs checking.
- Ask for options, then edit. Request several headlines or openings and combine the best parts.
- Cut generic phrases. If a sentence could appear on any company’s site, replace it with something only you could say.
- Check every claim. Numbers, quotes, comparisons and legal statements need a human check before they go live.
- Keep a style note. Save the instructions that worked and reuse them.
Where AI copy goes wrong
- Invented facts. Assistants can state things confidently that aren’t true. Verify before publishing.
- Sameness. If everyone uses the same prompts, the copy sounds alike. Your examples and opinions are what make yours different.
- Overstated claims. Ad copy that promises results you can’t back up creates legal and trust problems.
- Skipping the edit. A first draft isn’t finished copy. Read it aloud and cut anything you wouldn’t say.

Frequently asked questions
What is the best AI tool for copywriting?
There’s no single best one. A general assistant such as ChatGPT, Claude or Gemini covers most solo work. Teams that need brand controls and shared workflows should look at platforms like Jasper, Copy.ai or Anyword.
Are free AI copywriting tools good enough?
For drafting and brainstorming, often yes. Free tiers usually limit usage or features, so check the vendor’s page. Test with a real brief before you pay for anything.
Can AI replace a copywriter?
It speeds up drafting, but it doesn’t know your customers, your product or your risks. A person still decides what to say, checks the facts and owns the result.
Will AI-written copy hurt my SEO?
Google has said it rewards helpful content regardless of how it’s produced. Thin, unedited or inaccurate pages are the risk. Add real expertise, check facts and edit properly.
Which tool is best for product descriptions?
A general assistant works for a handful of products. For a large catalogue, a product-focused platform such as Hypotenuse AI is built for that job.
How do I keep my brand voice?
Write down your tone, words to use and words to avoid, plus two or three samples of your best copy. Paste them into every brief or save them as instructions where the tool allows it.
Do these tools work for ads and email?
Yes, as a source of first drafts and variations. Test the results the way you’d test any copy, and use the data to decide what stays.
Next step
Pick one assistant and one specialist tool, run the same brief through both, and keep whichever needs less editing. Add more tools only when a real gap shows up.
