Copywritely Review: SEO Writing Tool vs WebTextTool Compared

What Is Copywritely and What Does It Cost?

Copywritely is a content optimization tool that checks your writing for readability, plagiarism, and keyword density. The goal is straightforward: help you write content that both human readers and search engines can understand clearly.

At the time of this review, Copywritely was running a lifetime deal on AppSumo with stackable codes. A single code at $59 gets you one user, 50 document scans per month with a 5,000-word limit per document, unlimited rechecks on one document, and 50 SERP analyses covering your top 10 competitors. Stacking a second code bumps you to five users, 150 documents, and a 10,000-word limit. Three codes enables 10 users, 300 documents per month, 15,000 words per document, and 150 SERP analyses across 30 competitors.

For most bloggers, that 5,000-word limit on a single code should be plenty for standard posts. If you regularly publish long-form guides or lead magnets, you might need to stack a second code to get the higher word count.

Uniqueness, Keyword Stuffing, and Redundant Phrases

The first thing Copywritely checks is uniqueness, essentially a plagiarism scan. In testing with a 3,000-word fitness lead magnet, it correctly identified the content as 100% original.

The keyword stuffing checker is genuinely useful. It scans your document for overused search terms, including a stemming toggle that groups word variations together. If you're using "diet," "diets," and "dieting" too frequently, stemming will catch that pattern. There's also a stop words analysis that flags common filler words like "to," "you," and "the." While you obviously can't avoid these entirely, overusing them can signal lower quality to search engines. Clicking on any flagged word highlights every instance in your document, making it easy to track down problem areas.

The redundant phrases section identifies filler language that doesn't add value. Words like "probably," "happened," and "it seems" get flagged as phrases you could tighten up. If you've ever read "Writing Without BS," you know how much sharper your writing gets when you strip out these verbal crutches. The interface works the same way here: click a phrase and it jumps you right to each occurrence in the text.

Readability Analysis

Copywritely's readability section gives you two key metrics: a grade level and a Flesch reading ease score. The general rule of thumb for reaching a broad audience is to aim for around a third-grade reading level, though most web content lands somewhere between fifth and eighth grade.

The test document came back at a sixth-grade reading level with a Flesch index of 53. For context, you want to stay under 70 on the Flesch scale for content to be considered easy to read, so a score of 53 means the content is a bit too complex for casual readers. This kind of feedback is actionable because you can go back through your document, shorten sentences, swap in simpler words, and watch the score improve.

There's also a rhythmic monotony check, which flags repetitive sentence structures. The test document passed this one cleanly. It's a small feature, but sentence variety matters more than most writers realize when it comes to keeping readers engaged.

Morphology: The Confusing Section

Here's where Copywritely starts to lose points. The morphology section analyzes the balance of different parts of speech in your writing, including things like passive verbs, prepositions, participles, introductory statements, and abstract adjectives. In theory, this could be valuable feedback.

In practice, it's poorly explained. The tool flags issues like "you used the word 'as' twice in one sentence" or "introductory statements appear 113 times," but it doesn't educate you on why that matters or what to do about it. You get percentages and targets without context. Unless you have a strong background in English grammar, you'll likely find yourself staring at this section wondering what action to take.

To make matters worse, there's a caching bug where edits to the document don't always register in the re-analysis. Even after clearing the browser cache and refreshing, changes weren't reflected. For a tool that's supposed to help you iteratively improve your writing, that's a frustrating experience. This section has potential, but it needs significantly better user guidance to be practical for most content creators.

Grammar Checking: The Most Useful Feature

The grammar section turned out to be Copywritely's strongest feature. It flagged 26 errors in the test document, covering spelling mistakes, hyphenation issues, and style suggestions. The suggestions were mostly practical and easy to implement.

For example, it caught "try and use" and suggested "try to use," which is a legitimate improvement. It also flagged a punctuation issue where "until" started a sentence without a proper second clause, suggesting a comma splice instead. Working through the suggestions knocked the error count from 26 down to 22 in just a few minutes.

That said, it's not perfect. One suggestion wanted to change "gain it back" to "gain it backs," which is obviously wrong. Any grammar tool will occasionally stumble on informal, conversational writing because the rules of casual English don't always match formal grammar standards. You'll need to use your judgment on which suggestions to accept. Overall though, this section provides genuinely actionable feedback and helped tighten up the writing in noticeable ways.

Chrome Extension: Analyzing Existing Blog Posts

Copywritely includes a Chrome extension that lets you analyze any live web page with a single click. Hit the extension icon on a blog post, and it opens a new tab with the full Copywritely analysis of that page's content.

The convenience is nice, but there are a couple of issues. First, it took well over a minute to process and return results, so don't expect instant feedback. Second, and more importantly, clicking the extension immediately consumes one of your monthly document credits with no confirmation dialog. If you accidentally click the wrong Chrome extension (and we've all mixed up tiny toolbar icons), you've just burned a credit. A simple "Are you sure?" prompt would go a long way here.

There's also a minor display bug where HTML code occasionally bleeds into the content view. The tool offers a toggle between content and HTML views, but in HTML mode some raw code shows up where it shouldn't. It doesn't make the tool unusable, but it's the kind of rough edge that suggests the product needs more polish.

Copywritely vs WebTextTool (TextMetrics): Head-to-Head

WebTextTool, which has since rebranded to TextMetrics, was a previous AppSumo deal with similar functionality. Running the same test content through both tools reveals some clear differences in approach.

TextMetrics asks for more context upfront: page title, URL, description, and a main keyword. This lets it give you SEO-specific guidance that Copywritely doesn't offer. It suggested adding the target keyword to the page title, which immediately bumped the optimization score from 26% to 41%. It also provides recommendations for headings, image usage, bold and italic formatting, and overall content structure. These are practical, actionable suggestions that go beyond pure grammar checking.

The content analysis in TextMetrics also feels more user-friendly. It segments spelling errors separately from other issues, estimates reading time, and identifies the target audience sentiment. When it flags something like passive voice, it explains what passive voice is rather than assuming you remember from high school English. The readability suggestions tell you what to do in plain language instead of throwing grammar terminology at you.

One particularly useful feature: TextMetrics tells you the targeting audience reads as "neutral" and the sentiment as "positive." If you're writing for a specific demographic, that kind of feedback helps you adjust your tone.

Final Verdict: A 7.1 Out of 10

Copywritely is a decent content optimization tool that needs more polish before it can truly compete. The uniqueness checker, keyword stuffing analysis, and grammar section all provide real value. The readability scoring gives you a clear picture of where your content stands. But the morphology section is confusing, the Chrome extension lacks a confirmation step before burning credits, and there are caching bugs that undermine the editing workflow.

The final score here is a 7.1. It's an okay tool with room to grow. If you already own WebTextTool (TextMetrics), there's not enough here to justify adding Copywritely on top of it. TextMetrics offers more actionable SEO guidance, better-organized feedback, and a more intuitive interface overall.

However, if you missed the TextMetrics deal and you're looking for a budget-friendly content optimization tool, Copywritely could be worth picking up. It covers the basics of plagiarism checking, readability analysis, and grammar correction at a reasonable lifetime price. Just go in knowing that you'll likely outgrow it if a more refined tool comes along.
