Frase vs Claude: Which one offers better results for AI-driven content? (Tested with examples)

Claude’s known for logic, but how does it compare to Frase when it comes to impactful AI content at scale?

Put them side by side, and you’ve got two powerful AIs aimed at solving the same problem—faster content, less revisions, more impact.

But they go about it in totally different ways.

Claude brings general reasoning and broad capabilities. Frase adds multi-source research, on-brand fine-tuning, and SEO optimization tools—all built-in.

In this comparison, we’ll put both to the test across real marketing tasks. Same inputs, different engines. Let’s see what happens.

Comparing Claude to Frase is NOT like comparing Claude to ChatGPT. This isn’t necessarily about which AI is smarter (e.g. coding, reasoning…). Instead, we’re here to see which one actually helps marketing teams get results, both for short and long-form content. That means, for example:

• Content that makes readers stay, learn more about your business, or turn into leads
• Research that makes others see you as an expert and trust your services more
• A competitive SEO strategy designed to outperform top-page results over time
• Repurposed social media content that gets engagement
• Landing page sections, emails, or ads that convert

If any of these goals is on your list, soon you’ll see why we recommend Frase. Want to skip the test and start creating? Try the Frase free trial here (no card needed).

And if you want to see exactly where that difference shows up, everything you need to know is below.

Frase is an AI marketing platform designed to create impactful content at scale across every channel—blog posts, landing pages, emails, social, and more. It combines SEO research, writing, and brand controls in one platform, so your team can produce content that gets results with fewer steps, less guesswork, and zero need for extra tools.

Here’s what it’s like to use Frase for the first time:

For better results, it’s recommended to start with the Frase AI Knowledge Base: you can upload samples and brand guidelines to make sure it writes just like you.

As for the actual AI writing, there are many ways to approach it:

• (Recommended) SEO Workflow: You pick a main keyword, Frase does the research, and then you can write prompts within* the editor with full control over your content.
• Rank-Ready AI Document: A setup wizard that turns minimal input into full-fledged articles in under 5 minutes.
• Blank document: Self-explanatory. There’s no SEO research, but you can always add it later from the right sidebar as shown below:

What kind of research? Everything from the top ranking competitor content, to the questions your ICP is asking on forums, up to date stats, and more:

Once you’re ready to start writing, you have several customizations:

The most notables are:

• The option to select a Brand Voice (right corner) to write in your tone
• The “@” prefix to reference documents (e.g.  an internal research document or product specification sheet you have uploaded and want to Frase’s AI to reference in your content generation)
• The Web Search (left corner) to write with live data from the top SERP results

And of course, the prompt. Once you find an effective prompt for a certain task, you can save it as an “AI Tool” to load later in one click (e.g. Repurpose for Instagram). But if that’s too much work, you can always use the ones from the Featured library and Community:

Frase has already been proven to perform for articles, cold emails, and anything in between, which makes it a versatile platform to manage your entire content strategy.

Claude is a family of large language models (LLMs) developed by Anthropic, an AI company that “puts safety at the frontier.” Similar to ChatGPT, Anthropic brands Claude as an AI assistant with similar features, including web search:

Claude also supports basic brand customization: you can add your work role and write personal preferences, acting as a custom GPT:

Now, according to Claude itself, there’s one big difference with ChatGPT. Claude “Tends to give more nuanced, measured responses rather than being overly confident or definitive about uncertain topics.” When we asked how that affects marketing content, it responded:

By default, Claude might “actually work against traditional direct-response marketing principles.”

Meaning? This writing type can be useful if your focus is article writing and building trust. But will this content compel readers to check your landing page, give their emails, or view your case studies? Not so much.

Regardless, we will test Claude both for content and copywriting just in case it’s more capable than it seems.

So we can test all the top use cases, let’s consider this example:

You’re an ecommerce entrepreneur selling a service (agency) or product (e.g., software) to business owners. The first goal of your content strategy might be to show expertise in your niche for a highly relevant keyword. For example, “how to write product descriptions.”

The process may look like this:

1. Research the content, not just to fulfill the search intent, but to outperform page-one competitors
2. Write the content in the most efficient way
3. Optimize the content for SEO and conversions

And as for copywriting, let’s say you have a relevant free resource: “the 10-step product description checklist to boost sales by 60% in 30 days”, sent after collecting the reader’s email.

You could promote this as an exit pop-up, a banner in the middle of the article, or a call-to-action at the end:

• Write lead magnet copy to complement the article

Let’s see how Claude and Frase perform.

End Result: A complete content brief—headlines, questions, stats, angles—enough to jump straight into writing without doing any extra research.

Starting with Claude, there’s no built-in research workflow, so we’ll just prompt the earlier paragraph in the chat. The output? See below:

Claude provided headline variants, but not actual headline structure. There are useful stats, but no sources. The content ideas seem valuable, but did Claude look into the top pages to see what’s actually out there?

Here’s the problem: if everyone used this method to rank for this keyword, without SERP research, there’s no guarantee it will stand out or rank. It still needs extra research.

Switching now to Frase: SEO Workflow > enter query “how to write product descriptions.” Done in two clicks:

The result? Guidelines and outlines based on pages that are already ranking:

Frase also knows the People Also Ask questions (PAA), not just what Claude “thinks” is relevant. You also get verifiable statistics:

Effortless.

Sometimes you’ll want more control over your content. And for that, Frase also makes competitor research easy:

The sidebar Outline tab previews live competitor outlines, domain rank, word length… so you can notice what’s working and model it.

In short, Frase did pass the research test better than Claude (missing outline, unverified stats).

End Result: A draft that feels polished and compelling enough to keep the reader hooked without needing major rewrites.

Using the earlier briefs, let’s see what Claude generated (full version here):

Once you have a closer look, Claude does sound quite natural and practical in its advice. But will it convert? That’s a different story.

Readers may spend minutes—maybe seconds— to find the info they need or otherwise leave, but Claude tends to write as long as possible. It’s too easy to scroll down and close the page because of a daunting text wall.

As for Frase, it generated this version (full document here):

So how good is it? From the start, you’ll notice the article is more scannable and organized (probably due to getting the research test right), as well as being fairly optimized by default.

Which one is the winner? They’re both valid drafts, but Frase has a slight edge in readability according to HemmingwayApp:

(The simpler your message, the more likely it is to convert.)

Frase scored a Grade 11 while Claude scored 14, which makes Frase more likely to perform and need fewer revisions.

End Result: Clear confirmation that your content matches or beats top pages—keywords covered, topic gaps filled, structure aligned—ready to rank.

Claude does not have built-in SEO tools, but that doesn’t mean it can’t get the basics right. It can still brainstorm for keywords, look up specific URLs, and get you 80% there. But will it be enough to outrank?

The original post had a 39% topic score as opposed to 64% for the Frase article. There are two ways you can “optimize” the Claude article:

1. Copy-paste 5-10 top-page competitor links and ask to gather the most relevant keywords. On a second prompt, ask to rewrite the post with more keywords.
2. Simply ask Claude to rewrite while optimizing the SEO for the main keyword.

For simplicity we did the latter and, sure enough, Claude jumped from 39% to 48%. But at what cost? 

The readability plummeted to post-graduate level. At that point, you’re writing just for the algorithm which, at best, would rank you at the bottom of page 1. That’s because the 6 highest pages score over 70%:

While the 100% score doesn’t guarantee results, a 48% + bad readability isn’t exactly reassuring. Also note: you wouldn’t even know that the Claude version isn’t good enough without checking on Frase or other SEO tools.

So how do you optimize keywords on Frase? You select the missing ones, add them to an in-line prompt, and review:

What other keywords should you add? Simple. The Explore Topics button shows you all the “topic gaps” for each competitor, AKA ranking opportunities:

And for more technical SEO tracking, Frase has the Google Search Console integration. That’s more than enough to pass the optimization test, unlike Claude.

End Result: A short, compelling opt-in section that seamlessly promotes your free resource in the article. Clear, specific, and ready to drive email sign-ups without rewrites.

Fast-forward: your AI article is live, climbing the ranks and bringing traffic. Now, you want to turn readers into email leads by promoting a free resource mid-content, adding a copy section like this:

Our Prompt: “Write a short copy opt-in section. We will ask readers to enter their emails to get a free resource, the 10-step product description checklist to boost sales by 60% in 30 days. This opt-in panel should include the main headline, subheadline, benefits bullet point list, button text, and social proof elements.”

For all its shortcomings, Claude did surprisingly well at this test:

Looks almost like a human-made opt-in page. And as for Frase, there is a secret weapon:

You see, SEO tools aren’t just for ranking, but also for saving research time. Even if you don’t know anything about writing opt-in pages, Frase can look up the best practices based on top competitors and their latest research. This copy section from above seems similar to Claude, but it is different: Frase wrote this using proven copywriting trends.

That’s a lot of weeks you save on A/B testing and more conversions you get from the start. Both pass the test, but Frase has a different edge.

You’ve seen how both AIs perform across real marketing tasks. But if you’re still deciding, the full picture matters—features, brand control, ease of use, integrations, and pricing.

Let’s break it down.

How flexible is Claude vs Frase when it comes to content diversity? Can they cover the full marketing spectrum or only articles?

At first, Frase seems like a tool just for long-form content SEO. But as we’ve seen on the tests, it does far more than that, including short-form copy:

It may seem Claude can write any content type. But when it comes to effective marketing content, as mentioned earlier, it’s not the best choice:

It’s not that Claude can’t convert, but by default, it will need more work to be guided on the prompts. And without SEO optimization tools, it’s not truly a complete solution.

Buyers associate strong brands with higher quality, status, or reliability, making them convert far more for similar offers. Now, can these AI platforms achieve this, or do they sound like everyone else?

Claude already has a branding tool (Custom Styles):

Here, you choose one of the five (e.g. Specific Voice & Tone), write a prompt, and then the style will show up in the drop-down editor. It’s simple but will still need testing to see if your brand description matches the intended result.

On Frase, everything is more organized within the AI Knowledge Base, this is your full kit to train the AI to write like one of your team and consists of Brand Voice, Style Guide, and Reference Docs:

Not only can it analyze your brand voice from text samples, but you can regulate every variable. And with Reference Docs, you can upload documents including brand guidelines, messaging matrixes, and internal research documents, so that Frase’s AI has the internal knowledge to understand your brand, products, and tone—before it starts writing.

Once you’ve uploaded your documents, in your next prompt, you can reference any document you like and use your organization’s unique expertise to inform the content you generate.

Claude can’t do this unless you attach files for every conversation, which is why we lean more towards Frase as for branding.

Which one saves you learning time, not just content time?

Claude is a blank canvas. Starting is easy, but getting the exact output you want is more complicated. That’s because there are no templates, document memory, or even the Community custom GPTs that OpenAI does have.

As for editing, Claude is still a chatbot. You can’t overwrite directly or generate inline content with document context, only if you copy-paste and switch tabs. There are extensions for Google Docs and such, but it still can’t write directly in your file, only suggest content from a sidebar.

Instead, Frase gets you a full-fledged document editor with an in-line AI assistant.

Let’s say you don’t need that much control and just want the easiest, fastest way to write great content. Well, there’s an  instant Rank-Ready AI Article feature for that:

Simply enter your search query, set your parameters, and the AI will generate a long-form piece of content for you that’s fully optimized and ready to rank in minutes.

Frase may seem complex at first*. That’s because it offers multiple paths to meet your goals, whether you’re looking for an AI copilot or content on autopilot.

Can you use both tools in your typical workspace?

As a broader tool, Claude should have more integrations (it doesn’t).

To integrate Claude with Slack, Google Docs, etc… you have two choices:

• Get the Anthropic API Platform, make the scripts, and pay per token
• Find a third-party app with the integration you want, which often have their own pricing

Frase also has a fixed-price API aimed at large-scale businesses. But what about ready-to-use, one-click integrations?

Frase connects to Google Search Console, Google Docs, WordPress, and Slack. Unlike Claude, there’s an official Chrome extension that syncs with your in-platform account to use Frase anywhere.

Assuming no annual commitment, Claude ranges from $20 (Pro) to $100 per month (Max), per person. The Frase monthly plans range from $45 to $115, but you can also opt for the no-subscription option and choose bundles of Rank-Ready AI Articles starting from $2/article.

Marketers seem content with both: Frase averages 4.8 stars with ~300 reviews and Claude scores 4.4 with 56 (G2). 

Let’s look at what you’re getting on both platforms:

Note: Claude has a “cheaper” option for those who want full access for their team but don’t want the $100 tier: Team Pro. Instead of $20/mo, it’s $30/mo per person, but there’s a minimum of five members to subscribe.

A big plus from both platforms is usage-based pricing. You get ~95% of the premium AI features at the lowest paid plan (Claude Pro, Frase Starter). You don’t have to worry about upgrading until your content starts getting results and growing your business.

Despite Frase Professional being $15 higher, it already includes 3 seats instead of one in Claude Max ($25 for additional ones instead of $100).

The instant Rank-Ready AI Articles with no subscription required is also a big win for Frase in terms of flexibility. You can choose to purchase just one of these articles for $3.50 and get a long-form, SEO-optimized article in minutes, or buy in bundles and the cost goes down to $2 per article. There’s no monthly payments needed here, you can simply buy what you need when you need it. 

Another key point is reliability. Claude Pro offers “More Usage*” which—if you used ChatGPT before—it means sometimes, it won’t be as responsive or fast due to network volume. There are no usage limit guarantees on Claude. But on Frase, at least you know what you’re getting.

While Frase has variable limits for SEO-researched posts, in-line AI content is unlimited for as many documents as needed. It’s also the only one with a no-credit card free trial. 

If your team’s creating content across channels, Claude can help—but only with guidance, prompts, and post-edits. Frase cuts out all of that. It gives you the research, structure, brand voice, and keyword tools in one place.

That’s less time stitching tools together, and more time publishing content that moves the needle—blog posts, landing pages, emails, all of it.

You don’t need to be an SEO expert or spend hours researching briefs. You just need a system that works from start to finish.
