Grammarly vs Anyword: Which AI writing assistant is right for you?

Choosing an AI writing tool can feel like staring at a giant wall of cereal boxes in the supermarket. There are so many options, and they all claim they will make your life easier. It's hard to know which one you actually need. Two of the biggest names you'll come across are Grammarly and Anyword, but they're built for completely different tasks. Think of Grammarly as the meticulous editor who polishes your final draft, and Anyword as the creative copywriter who dreams up catchy ad slogans.

I've found myself jumping between a few of these tools depending on the project. Grammarly's been a lifesaver for tightening up my grammar and tone, but when I need something more creative, I've had some great results with Sudowrite's prompts

Our goal here is to give you a straightforward, side-by-side look at both tools so you can figure out which one makes sense for your work, as shown in the graphic below.

But what if you need more than just an editor or a copy generator? What if your job is to create a complete, ready-to-publish blog post from the ground up? That’s a different challenge entirely, and it’s where tools like the eesel AI blog writer come into play, turning a single keyword into a full article. We’ll get to that a bit later.

What is Grammarly: The digital proofreader

You've probably seen Grammarly's ads or its little green icon pop up somewhere. At its heart, Grammarly is a writing assistant that’s all about improving text you’ve already written. Its main job is to act as your digital proofreader, catching mistakes in grammar, spelling, and punctuation.

But it does more than just fix typos. It also gives you suggestions to make your writing clearer, more engaging, and hit the right tone, ensuring you sound confident, friendly, or whatever you're going for. It’s available pretty much everywhere you write, with browser extensions and apps for Google Docs, Microsoft Word, and other platforms.

They recently added GrammarlyGO, their generative AI feature. It can help you brainstorm ideas, compose short bits of text, and rewrite sentences, acting as a handy assistant inside your normal editing flow. It’s for a wide audience: students who want error-free essays, professionals writing important emails, and teams trying to keep their communication consistent.

What is Anyword: The performance copywriter

Anyword, on the other hand, is a specialized AI copywriting tool made specifically for marketing and sales teams. It isn't focused on fixing your grammar; it’s all about generating and optimizing copy that convinces people to click, buy, or sign up.

Personally love ChatGPT, Jasper, and Canva’s AI tools — they save me hours on content, visuals, and ideas. Also Zapier for automations and Anyword for ad copy optimization. Simple tools, real impact. 🚀

Its most interesting feature is the Predictive Performance Score. As it creates copy, it gives you a score that predicts how well that specific version will connect with your audience. This is a big deal for A/B testing because you can start a campaign with a data-backed guess about what will work best.

Anyword is heavily focused on maintaining a consistent brand voice and is loaded with templates for ads, landing pages, social media posts, and product descriptions. It’s the tool of choice for performance marketers, advertisers, and content creators who are focused on conversion rates and need to produce a lot of high-performing, short-form copy.

Feature breakdown: Grammarly vs Anyword

While both tools use AI to help with writing, they have very different end goals. Grammarly is about perfecting the words you already have on the page, while Anyword is about creating new words designed to sell. Let's see how their features compare.

Core purpose: Editing vs. generating

• Grammarly: The whole platform is built around correction and enhancement. It works like a super-smart proofreader, catching errors as you type and offering suggestions to improve your style and tone. It takes what you've written and helps you make it better.
• Anyword: Anyword is all about creation and optimization. You give it a prompt, and it generates several versions of new copy from scratch, often using proven marketing frameworks. Its goal isn't just to be grammatically correct but to drive clicks and conversions.

Generative AI capabilities

• Grammarly (GrammarlyGO): This is a general-purpose generative AI assistant that’s part of your writing workflow. You can use it to brainstorm ideas, create an outline, write a quick paragraph, or rephrase a sentence you’re struggling with. It’s a flexible helper for everyday tasks.
• Anyword: This is a purpose-built copy generator. You pick a specific use case, like a "Facebook ad" or "landing page headline," give it some info about your product, and the AI produces several tailored options. Each option comes with performance predictions, making it easier to choose what to A/B test.

Analytics and performance insights

• Grammarly: Its analytics are all about writing quality. You get readability scores, a breakdown of your tone, and data on your most common errors. The Business plan provides team-level analytics, showing how well everyone is following the company style guide and tracking writing improvements over time.
• Anyword: This is where Anyword really stands out. Its Predictive Performance Score is the main attraction. It gives every piece of copy a score that forecasts its conversion potential and even offers a glimpse into the demographics it’s most likely to appeal to. It’s all about predicting business results, not just writing quality.

Brand voice and consistency

• Grammarly: The Business plan allows you to set up a style guide. This helps your whole team stay on the same page with things like terminology, capitalization, and formatting. The tone detector also helps individuals see if their writing matches the intended vibe (e.g., formal, confident, friendly).
• Anyword: Anyword lets you create a detailed brand voice profile by analyzing your best-performing content. Once that’s done, the AI generates all new copy in that specific voice. This makes sure everything from your Facebook ads to your email subject lines sounds like it’s coming from the same brand.
