Overview

Frase brings topic research, long-form drafting, search optimization and AI-visibility monitoring into a publishing workflow. It is best suited to content and SEO teams that need both conventional search work and visibility in AI answers. Its breadth is a strong fit for teams consolidating those tasks, but article, audit-page and seat quotas make plan selection consequential.

Work can move from research and brand-voice drafting to scoring for Google and AI search, publishing, and monitoring. Frase Answers responds to visitors using a site's own content with citations and captures the questions they ask. Content Guard watches rankings and traffic decay, then drafts fixes for approval; automatic publishing can be enabled for any content type.

AI Visibility monitors citations across ChatGPT, Perplexity, Claude, Gemini and Google AI. Alongside SEO features such as rank tracking, site audits, backlink analysis and competitor research, Frase offers a REST API with content, SERP and audit endpoints and webhooks on every plan. MCP and CLI support connects workflows in Claude, ChatGPT, Codex, Cursor and terminals.

Key features

Research, writing and monitoring

Frase combines research, long-form writing, SEO features and GEO scoring, with brand voice controls and native writing in more than 70 languages and locale variants. That combination suits teams managing a steady content pipeline across markets. The practical constraint is throughput: each paid plan caps monthly articles and audit pages, so high-volume teams should compare their publishing and monitoring needs against those quotas before committing.

Publishing and integrations

Frase can publish to WordPress, Webflow, Sanity and Wix, or host content on FraseCMS. It has 16 native integrations, including Google Search Console, Google Docs, Notion, GitHub, Linear, Slack, Zapier, Make, n8n, Claude, ChatGPT and MCP. That gives teams several ways to connect existing tools, while the API and agent access offer additional routes for custom workflows.

Answers, control and security

Frase Answers uses a site's own content to respond to visitors with citations and collects the questions they ask. Team permissions separate billing and administration from editing and read-only access: Admins manage billing, Editors create and edit, and Viewers can read. Frase states that it is SOC 2 Type II attested and GDPR compliant, with encryption at rest and in transit, access controls, audits and vulnerability scanning. It also says customer data from Google Workspace APIs and other platforms is not used to train generalized AI or machine-learning models.

Pricing

Frase offers a 7-day trial capped at 5 articles, 50 audit pages, 25 AI prompts and 3 seats. The trial lets a small team explore the workflow, but its article quota is limited. FraseCMS Free is a separate hosting tier: it allows 100,000 page views/month and 25 GB bandwidth, with a Powered by Frase badge.

Plan	Price	Limits and fit
Starter	$39.00 USD per month billed yearly; $49/mo month to month	1 seat, 1 site, 10 articles/month, 50 audit pages/month and Content Guard on 10 pages. A lean fit for a solo operator on one site; the article and audit caps leave little room for a large content program.
Professional	$103.00 USD per month billed yearly; $129/mo month to month	3 seats, 5 sites, 40 articles/month, 250 audit pages/month and Content Guard on 75 pages. A better fit for a small team managing several sites, though its seat and output limits still bound growth.
Scale	$239.00 USD per month billed yearly; $299/mo month to month	5 seats, up to 10 domains, 100 articles/month, 1,000 audit pages/month and Content Guard on 300 pages. The largest self-serve content and monitoring quotas suit a growing operation, but teams needing more seats or capacity should consider Enterprise.
Enterprise	Custom pricing	Custom seats, domains, limits and API access, plus white-label reports, a branded client portal, SSO and SAML. It is aimed at organizations needing tailored capacity or enterprise access; it also includes a dedicated account manager and SLA.
FraseCMS Basic	$19.00 USD per month	250,000 page views/month, 100 GB bandwidth, a custom subdomain or subdirectory, and no Frase badge. A modest hosting upgrade over Free.
FraseCMS Pro	$99.00 USD per month	1,000,000 page views/month, 500 GB bandwidth and dedicated support. Best for publishers needing more hosting capacity and support.

Yearly billing saves 20% on the monthly rate. The paid content plans are priced around seats, sites or domains, and monthly production and audit quotas; choose by expected volume rather than headline price alone. FraseCMS plans cover hosting capacity and should be considered separately from those content-plan limits.

Platforms

Frase is available on the web, through an extension and via API. The REST API is available on every plan, while MCP and CLI let teams use Frase through Claude, ChatGPT, Codex, Cursor and terminals. That is a useful range for teams that want both an interface and programmatic access.

Who it's for

Content marketers, SEO professionals, agencies, enterprise content teams, freelance writers and publishers are among Frase's intended users. The strongest fit is a team that wants research, writing, optimization, publishing and AI-citation monitoring in one workflow, especially if its stack benefits from API, MCP or CLI access. A solo user or small team with modest output can start on Starter; teams with many collaborators or unusually high content volume may find its seat and quota boundaries restrictive.

Pros and cons

Pro: Research, long-form writing, SEO and AI-visibility monitoring sit in one workflow, reducing the need to split those jobs across separate tools.
Pro: The API is available on every plan, with content, SERP and audit endpoints plus webhooks; MCP and CLI extend access to agent workflows.
Pro: Publishing to WordPress, Webflow, Sanity and Wix, alongside FraseCMS hosting, gives teams several publishing routes.
Pro: More than 70 languages and locale variants support teams publishing beyond English.
Con: Starter's 10 articles and 50 audit pages per month, plus its single seat and site, make it a poor fit for a busy multi-person program.
Con: Higher quotas require a substantial step up in monthly price, and Enterprise uses custom pricing.
Con: FraseCMS Free carries a Powered by Frase badge; removing it requires Basic or Pro.

Alternatives

For a tightly capped free SEO-writing workflow, GSEOeditor offers 25 searches and 25 AI credits total, one workspace and 10 pages, with no time limit or credit card required. It is a narrower starting point than Frase's monthly article and audit plans.

Hovers is another freemium option with a free plan and free trial. Consider it when you want to compare a different free entry point.

PageOptimizer Pro is worth comparing if a paid plan centered on SEO optimization and AI visibility suits your needs: Basic is $40.00 USD per month and includes 20 POP credits/month, unlimited domains, POP AI Writer and AI Visibility Tracker.

YourText.Guru offers a freemium option and free trial; compare it if you want another SEO-focused writing platform.

Originality.ai is a more focused alternative if AI detection is the priority: its free Basic plan provides AI detection only, with 3 scans per day and 2,000 words per scan.

Rankable may suit teams prioritizing recurring site audits and fixes: its $99.00 USD per month Starter plan covers one website, up to 500 pages, weekly audit and fixes, up to 60 SEO changes/month and 4 articles/month.

DiagnoSEO is a lower-priced paid option, with its Basic plan at $9.00 USD per month for 20 tools, 60 credits and 5 projects.

GazeSEO has a free Starter plan with one project, one seat, 150 content AI credits and up to 3 optimized content items.

Verdict

Frase is a strong choice for content and SEO teams that want a connected workflow from research and drafting through publishing and AI-visibility monitoring, with API access available at every plan level. Its multilingual writing and publishing options add range, but the article, audit-page and seat caps demand careful plan selection. Look elsewhere if those quotas do not match your output or if you need a lower-cost tool focused on a narrower job.
