If you’re choosing between Semrush and Frase, you’re really choosing between two different jobs. Semrush is a full SEO and competitive research platform with AI writing assistance bolted onto a much larger toolkit. Frase is a focused content research and brief-building tool built specifically around the workflow of researching, outlining, and optimizing individual articles. Both use AI to speed up content work, but they solve different problems at very different price points. Here’s how to tell which one actually fits your workflow.
Where Each Tool Wins
Semrush earns its keep as an all-in-one SEO suite. Beyond content, it covers keyword research, backlink analysis, site audits, rank tracking, and competitor research — the AI writing assist is one module inside a much bigger system. If your work involves technical SEO, competitive intelligence, or managing SEO strategy across a site (not just producing content), Semrush’s breadth is the point. You’re paying for a platform that can inform decisions well beyond what to write next: what to fix on-site, who’s outranking you and why, where your backlink profile stands, and how your visibility trends over time. Content creation is one piece of a much larger puzzle Semrush is built to solve.
Frase wins on focus and speed for content teams. It’s built specifically to research a topic, generate an SEO brief based on top-ranking competitors, and help writers optimize drafts against that brief — without the overhead of a full SEO suite. If your day-to-day is “we need to publish optimized content efficiently,” Frase strips out everything that isn’t directly useful to that task. Content teams, freelance writers, and agencies producing high volumes of articles often find this narrower scope makes for a faster, less cluttered workflow than trying to use a fraction of a larger platform like Semrush.
Pricing and Value Tradeoffs
The price gap here is significant and worth weighing carefully. Semrush’s entry-level plan is the “SEO” tier (formerly labeled “Pro”), starting at $139/mo billed monthly, or $117.33/mo if you commit annually. That’s the cost of admission for the full suite — keyword tools, audits, tracking, and AI content features all bundled together.
Frase starts at $39/mo billed annually ($49/mo if you pay month-to-month), and it offers a 7-day free trial with no card required — a low-friction way to test the brief-building and optimization workflow before committing. For teams whose primary need is content research and optimization rather than broad SEO tooling, that’s a fraction of the cost for the specific job they need done.
The value calculation really comes down to what you’d actually use. If you’d only ever touch Semrush’s content/AI writing module and ignore the rest of the suite, you’re paying a premium for tools that sit unused. Conversely, if you need site audits, backlink data, and rank tracking alongside content work, Frase simply doesn’t offer that — you’d need to pair it with other tools, which adds cost and complexity back in.
Final Recommendation
Choose Semrush if you need SEO capabilities beyond content — site audits, backlink analysis, rank tracking, and competitive research — and want one platform to manage strategy and content together. It’s the better fit for in-house SEO teams, agencies managing full-service SEO for clients, or anyone whose job extends past writing and optimizing articles.
Choose Frase if your priority is producing well-researched, optimized content efficiently, and you don’t need a full SEO suite to do it. It’s the stronger option for content teams, freelance writers, and lean marketing teams who want SEO-informed briefs and optimization without paying for tooling they won’t use — and the low-cost annual plan plus free trial make it easy to validate the fit before you commit.
