TAMGIO vs Semrush AI Toolkit: An Honest Comparison

Competitor data as of September 2026 · source: Semrush — AI Visibility pricing, Semrush — plans

TAMGIO is a standalone AI-visibility analytics tool that measures how often a brand is mentioned, cited, and recommended in AI answers. Ongoing tracking runs on three engines — OpenAI web_search, Perplexity Sonar, and Gemini grounded search. Google AI Overviews (via SerpAPI) is added in Audit Mode, for four measured surfaces in total. Semrush AI Toolkit, by contrast, is an add-on module bolted onto Semrush's existing SEO suite that tracks prompt-level visibility mainly on ChatGPT and Google AI Overviews. Semrush's toolkit draws on a large existing dataset (26M+ prompts and responses) and a 0-100 AI Visibility Score inside the same dashboard you may already use for keyword rankings, while TAMGIO runs its own N-sample scans and keeps every scan's raw evidence attached to the metric it produced. The core difference is evidentiary: an TAMGIO number links back to the exact API response and timestamp behind it, while Semrush's score is read from its own aggregated index.

Who each tool is actually built for

Semrush AI Toolkit is aimed at teams already inside the Semrush ecosystem — SEO managers and agencies who want AI visibility sitting next to the keyword rankings, backlinks, and traffic data they already track. That's a real convenience: one login, one dashboard, one invoice. TAMGIO is built for a narrower job: proving, with evidence, what AI models actually say about a brand. If you don't need a full SEO suite and want a tool whose only responsibility is AI-answer measurement, TAMGIO is the more direct fit.

Engine coverage: three ongoing engines (four surfaces in Audit Mode) vs two

Ongoing tracking runs on three engines — OpenAI web_search (gpt-4.1-mini), Perplexity Sonar (always grounded), and Gemini grounded search. Google AI Overviews (via SerpAPI) is added in Audit Mode, for four measured surfaces in total; it is SERP-embedded and can legitimately be "no_surface" for a given search — a result TAMGIO reports openly rather than hiding. Semrush AI Toolkit currently covers ChatGPT and Google AI Overviews/AI Mode; Gemini support is listed as "coming soon," and independent reviews (Trakkr, Profound, 99signals, Rankability, Am I Cited) note it has no Claude or Perplexity coverage at the time of writing.

The evidence gap

This is where the two tools diverge most. TAMGIO reports Discovery visibility (mentions in unbranded questions) as its headline metric and backs every Mention Rate, Share of Voice, Citation Rate, and Prompt Coverage number with raw evidence — a dashed underline on the metric opens the actual API response, the citations returned, and the timestamp the scan ran. Nothing is a black-box score. Semrush's toolkit reports an aggregated 0-100 AI Visibility Score and Brand Performance metrics computed from its own dataset; several independent reviews describe the underlying queries as simulated rather than live user-query logs, and note that recommendations can be generic ("improve onboarding") rather than tied to a specific answer.

Prompt volume and methodology

TAMGIO treats AI answers as non-deterministic by design: users write or AI-generate 30-40 candidate prompts, approve them, and TAMGIO samples each one repeatedly because a single-shot answer isn't a trustworthy measurement. Semrush's standalone add-on ships with 25 tracked prompts per domain, with extra capacity sold in blocks of 50. Neither approach is wrong — they're built for different confidence levels of measurement.

We do the setup — prompts, tracking, reporting.

According to Semrush's official pricing page (as of September 2026), the AI Visibility Toolkit costs $99/month (per domain, billed annually) as a standalone add-on covering one domain and 25 prompts — across ChatGPT, Google AI, Gemini and Perplexity — with +$60/month per additional 50 prompts, and Semrush offers a 7-day free trial. It's also sold bundled into Semrush One plans (Starter $199/mo, Pro+ $299/mo, Advanced $549/mo monthly, discounted on annual billing). TAMGIO's Weekly Scan at $39/mo covers 30-40 prompts across 3 engines — below Semrush's standalone add-on with a wider prompt allowance; Semrush's advantage is being an add-on to the SEO suite you already pay for. TAMGIO offers no trial period — we do the setup instead; the figures are early-access pricing.

Where Semrush AI Toolkit genuinely does well

  • Large existing dataset (26M+ prompts/responses) powering a 0-100 AI Visibility Score with daily position tracking
  • Brand Performance reporting (share of voice + sentiment) that reviewers call intuitive for client-facing agency reports
  • One dashboard that correlates traditional SEO rankings with AI visibility — genuinely convenient for existing Semrush users
  • Discounted bundling through Semrush One for teams that also want full SEO and traffic toolkits

Bottom line

If AI visibility is one line item in a broader SEO practice you already run through Semrush, the AI Toolkit add-on is a low-friction way to see it next to your existing rankings. If you need to know — with evidence you can open and check — what AI answers actually say about a brand, TAMGIO is built for exactly that job: ongoing tracking on three engines (OpenAI web_search, Perplexity Sonar, and Gemini grounded search), with Google AI Overviews added in Audit Mode for four measured surfaces in total.

FAQ

Does TAMGIO replace Semrush?
No. Semrush is a full SEO suite with an AI-visibility add-on; TAMGIO is a dedicated AI-visibility tracker whose ongoing tracking runs on three engines — OpenAI web_search, Perplexity Sonar, and Gemini grounded search — with Google AI Overviews added in Audit Mode. Teams that need traditional keyword rankings alongside AI-answer evidence often use both rather than choosing one.
Which AI engines does each tool track?
Ongoing tracking runs on three engines — OpenAI web_search, Perplexity Sonar, and Gemini grounded search. Google AI Overviews (via SerpAPI) is added in Audit Mode, for four measured surfaces in total. Semrush AI Toolkit currently covers ChatGPT and Google AI Overviews/AI Mode, with Gemini listed as coming soon and no Claude or Perplexity coverage at the time of this comparison.
Can I see the raw AI answer behind a Semrush AI Visibility Score?
Semrush reports an aggregated 0-100 score and share-of-voice metrics computed from its own dataset. TAMGIO takes a different approach: every metric has a dashed underline that opens the exact API response, citations, and timestamp the number came from.
Is Semrush AI Toolkit cheaper than TAMGIO?
Semrush's AI Visibility Toolkit costs $99/month (billed annually; as of September 2026) as a standalone add-on for one domain and 25 prompts, or comes bundled into Semrush One plans from $199/month (Starter, monthly billing). TAMGIO's early-access pricing is public: Weekly Scan $39/mo · Daily + Competitors $99/mo · Agency / White-label $249/mo · one-off audit from $60 — setup included. Direct comparison: Semrush's $99 buys 1 domain and 25 prompts, TAMGIO's Weekly Scan covers 30-40 prompts across 3 engines; Semrush's advantage is living inside the SEO suite you already pay for.
