Frase vs Semrush AI (2026)

Frase

by Copysmith AI

Semrush AI

by Adobe

Pros

• ✓One agent covers research, drafting, SEO and GEO scoring, CMS publishing and rank-decay monitoring, with auto-publishing available on every plan.
• ✓Its own MCP server, listed in the Claude connector directory, plus a REST API with webhooks and a CLI on every plan, including the free trial.
• ✓Published prices on three self-serve plans with a 7-day no-card trial, and Starter holds at its limits rather than billing overages.

Limitations

• –Starter covers 10 articles, 50 audit pages and Content Guard on 10 pages a month, and holds at those limits until the plan is upgraded.
• –AI Visibility tracks ChatGPT and Google AI on Starter, and Claude and Gemini tracking starts on Scale at $239 a month billed yearly.
• –White-label reports, a branded client portal, SSO and SAML are Enterprise features with custom pricing through sales.

Pros

• ✓AI Visibility tracks brand mentions across ChatGPT, Google AI, Gemini and Perplexity with daily updates, alongside traditional rank data in the same platform.
• ✓Publishes an MCP server with documented setup for eleven clients including Claude, ChatGPT, Microsoft Copilot, Cursor and Perplexity, so live Semrush data reaches an AI assistant without CSV exports.
• ✓Pricing is public across every toolkit, with the annual and monthly rates shown side by side on every plan.

Limitations

• –AI Visibility is a separate subscription at $99 per month per domain and is not included in any SEO Classic plan, so full AI plus SEO coverage means paying for both or moving to Semrush One.
• –Neither SOC 2 nor ISO 27001 appears anywhere on the Semrush security page or in its source, which is a gap for buyers with a formal certification requirement.
• –MCP access is read-only on projects and consumes metered API units, and SEO Classic Business requires an API units package on top of the plan rather than including them.
