Semji vs Semrush

Often the right answer, and it is where teams that already own Semrush usually start. Keep Semrush for the jobs Semji does not do at all — the backlink index, Site Audit, PPC, local and PR — and let Semji own the AI-visibility-to-published-page loop. The overlap is prompt tracking and rank tracking, so teams usually consolidate the Content Toolkit and the reporting add-ons first, and keep the SEO Toolkit for as long as their link and crawl work needs it.

Three subscriptions. Semrush One Starter is $199 a month for the SEO and AI Visibility toolkits; the briefs, AI writing and WordPress publishing that act on what they find are the Content Toolkit at $60 a month; and white-labelled reporting with AI summaries is a Pro Report at $20 a month. That is $279 a month, and it buys one seat, one Brand Performance domain and 50 tracked prompts a day. A second person is $45 to $100 a month depending on tier, plus $99 a month per user for AI Visibility access. Semji is quote-based, one contract, and seats are part of the scope rather than a per-head add-on.

Semji tracks ChatGPT, Google AI Overviews, Gemini, Claude, Perplexity and DeepSeek — the same six on every plan, with no per-model add-on. Semrush's coverage is organised per report rather than per plan: Visibility Overview covers ChatGPT, Gemini and Google AI Mode plus AI Overviews, and Brand Performance adds Perplexity on a weekly refresh. Grok and Claude appear only under the Enterprise demo call to action as “Full LLM coverage”. Semrush's own pages describe prompt-tracking engine coverage inconsistently, so check the report you actually intend to use. Note the direction of the gap: Semrush covers Google AI Mode and Semji does not.

A lot, and pretending otherwise would waste your time. It has a real backlink index and a technical crawler, neither of which Semji has in any form. It ships sentiment and Share of Voice as defined metrics, and Semji ships neither. It has plagiarism and originality checking through SEO Writing Assistant. It tracks Google AI Mode. Its Enterprise AIO product does server log-file analysis to prove AI bots can reach your site, and it carries public references from household global brands at exactly the scale Semji sells into. It has an official app inside ChatGPT. It has a genuinely free plan that will show you an AI visibility score, mentions and citations for $0, and a seven-day Semrush One trial — Semji has no free tier, no trial and no published price. Its AI PR Toolkit goes after the outreach half of the GEO job that Semji only measures: find the media outlets LLMs trust in your niche, pitch them, and attribute the earned coverage back to the pitch. And it sells PPC, social, local and market intelligence besides, with prompt tracking across 220+ countries and Brand Performance across more than 68,000 locations. If your job spans all of that, one vendor for all of it is a real argument.

Semji is SOC 2 Type II certified, with SAML SSO and automated certificate rotation, and an MCP server using OAuth Auth Code with PKCE, a permission system and audited tool-call logs. Semrush's security page claims a PCI DSS Level 1 certificate, GDPR adherence, SSO SAML enabled on request, two-factor authentication, AES-256 at rest, TLS 1.2 or higher, annual penetration tests plus weekly tests of new features, a HackerOne bug bounty and a shared UpGuard profile. Semrush ships an MCP server too, included with Semrush One, though it publishes no authentication mechanism, permission model or tool-call logging for it. Neither SOC 2 nor ISO 27001 is published on that page, and the data centres it names are in the United States with no EU-hosted option published. That is a statement about their page on 1 August 2026, not about their company — if certification matters to your review, ask them directly.
