Frase vs Grammarly in 2026: A full content operating system vs the writing assistant that goes everywhere
Frase runs the entire research-to-publish-to-monitor loop for content teams starting at $39 a month. Grammarly rides along inside every app you already write in, correcting and rewriting as you go, free to start.
Frase
Grammarly- Frase covers the full SEO and GEO content loop: research, drafting, optimization scoring, CMS publishing, and ranking decay monitoring via Content Guard.
- Grammarly works inside 500,000+ apps and websites via browser extension, desktop app, Word plugin, and mobile, correcting grammar and rewriting as you type.
- Frase tracks AI visibility on ChatGPT and Google AI on its Starter plan, adding Perplexity on Professional. Grammarly has no AI visibility or GEO tracking feature at all.
- Grammarly has a genuine free plan with unlimited grammar and spelling checks. Frase has no free plan, only a 7-day trial across all tiers.
- Frase publishes directly to WordPress, Webflow, Sanity, and Wix. Grammarly does not publish anywhere; it edits inline in whatever tool you are already using.
Frase and Grammarly both use AI to improve writing, but they intervene at different points in the process. Frase is built to run the full content lifecycle for SEO and GEO work: researching a topic, drafting with a stored brand voice, scoring the result against both Google rankings and AI citation likelihood, publishing to a CMS, and watching for ranking decay afterward. Grammarly does not touch strategy or publishing at all; it lives inside Gmail, Google Docs, Slack, Word, and hundreds of thousands of other apps, correcting grammar and rewriting sentences as you type, wherever you happen to be writing. One is a production system for content teams, the other is an editing layer for anyone who writes.
The tools at a glance
Frase
Content operating system that runs the full SEO and GEO loop for in-house teams and agencies
Frase positions itself as a content operating system for AI search, covering research, drafting with your brand voice, SEO and GEO scoring, CMS publishing, and monitoring for ranking decay in one product. The idea is that no step should hand you an output and send you elsewhere to finish the job.
The brand voice layer reads your published content and generates drafts that sound like your team rather than a generic AI output, combined with live SERP and competitor analysis baked into the research step. Content Guard checks your live pages daily for ranking drops or AI answer changes, and when it finds decay, it drafts a fix and queues it for approval before anything republishes.
Pricing starts at $39 per month (Starter, billed annually) with real caps: 10 articles and 50 audit pages per month, and Content Guard watching only 3 pages. Professional at $103 per month lifts those limits and adds a content calendar; Scale at $239 per month covers 8 seats and unlimited sites for agency-scale throughput.
| Feature | Starter $39/mo (annual) | Professional $103/mo (annual) | Scale $239/mo (annual) |
|---|---|---|---|
| Articles per month | 10 | 40 | 150 |
| Content Guard (pages watched) | 3 | 15 | 50 |
| AI visibility tracking | ChatGPT, Google AI | ChatGPT, Perplexity, Google AI | All + AI crawler monitoring |

Grammarly
AI writing assistant for grammar, clarity, tone, and brand consistency across every platform you write on
Grammarly corrects grammar, improves clarity, suggests tone adjustments, and rewrites sentences across the web and desktop. It started as a grammar checker and has expanded into full paragraph rewrites, plagiarism and AI content detection, and enterprise brand tone tools, but it does not do content strategy, research, or publishing.
The core product is a browser extension and desktop app that sits alongside whatever you are already writing in: Gmail, LinkedIn, Google Docs, Slack, Microsoft Word. It augments your existing editor rather than replacing it, and Pro and Enterprise plans add full paragraph rewrites and defined brand tones that every team member is corrected toward.
For enterprise teams, Grammarly adds SAML SSO, data loss prevention, style guides, and analytics dashboards. Organizations report meaningful time savings at scale: one documented case saved $210,000 in nine months, another cut editing time by half. Free covers grammar and spelling with no character limits; Pro is $12 per month billed annually.

| Grammar and spelling corrections | ✓ | ✓ | ✓ |
| Full paragraph rewrites | ✗ | ✓ | ✓ |
| Plagiarism and AI detection | ✗ | ✓ | ✓ |
| Style guides | ✗ | 1 | Unlimited |

Considering AI Peekaboo alongside Frase and Grammarly?
Frase's AI visibility tracking is real but bundled: it only comes as part of buying the full $39-plus-per-month research-to-publish platform, and Perplexity coverage requires the $103 Professional tier. Grammarly has no AI visibility tracking at any price. If what you actually need is standalone monitoring of ChatGPT, Gemini, Perplexity, and Google AI Overviews and Google AI Mode, without committing to a content production platform or accepting no tracking at all, AI Peekaboo covers all five with a read and write API and white-label delivery from its $50 per month Starter plan.

FraseGrammarlyFraseGrammarlyFraseFrase and Grammarly rarely compete for the same budget line because they solve different problems in the writing process. Frase decides what to write and where it should go, then watches whether it keeps working after publication. Grammarly makes whatever you are already writing, anywhere you are writing it, clearer and more consistent. A content team that uses Frase to produce an article still benefits from Grammarly catching typos and tone slips before it ships, so the realistic comparison is less either-or and more whether you need one, the other, or both.
Bottom line
Choose Frase if you are running a content team that needs research, SEO and GEO scoring, publishing, and decay monitoring in one platform, and can absorb the learning curve that comes with that much surface area. Choose Grammarly if your problem is making everyday writing (emails, docs, Slack messages, drafts) clearer and more consistent, and you want it free or nearly free. Larger content operations often end up running both: Frase for production and Grammarly for the sentence-level polish inside whatever tool the draft happens to live in.
Frequently asked questions
Can Grammarly do the SEO research and publishing that Frase does?
No. Grammarly has no SEO scoring, keyword research, or CMS publishing features. It corrects and rewrites text inside the app you are already using, but it does not research topics, score content against SERP competitors, or publish anywhere.
Does Frase check grammar the way Grammarly does?
Grammar and clarity checking is not a core, dedicated feature of Frase the way it is for Grammarly. Frase focuses on research, drafting, SEO and GEO scoring, and publishing; it is not built as a real-time grammar correction tool for everyday writing across other apps.
Is there a free way to try Frase or Grammarly?
Grammarly has a genuine free plan with unlimited grammar and spelling checks and no time limit. Frase has no free plan at all, only a 7-day trial across all paid tiers, so you need to decide relatively quickly whether the full platform is worth committing to.
Which tool tracks AI search visibility, like ChatGPT citations?
Frase tracks AI visibility on ChatGPT and Google AI starting on its Starter plan, adding Perplexity on the Professional tier. Grammarly has no AI visibility or citation tracking feature of any kind; it is focused entirely on writing quality, not search or AI answer engine performance.
Can an agency use Frase and Grammarly together for client work?
Yes, and many teams do. Frase's Scale plan supports 8 seats and unlimited sites for agency-level content production and publishing, while Grammarly Enterprise adds brand tone consistency across every writer on the team. Using Frase for the production workflow and Grammarly for inline polish covers more of the writing process than either tool alone.
