99Visibility vs Semrush AI Visibility Toolkit

About the Semrush facts on this page. We checked them on Semrush's AI Visibility Toolkit pricing page on 17 October 2026, and each carries that date. Anything that page does not state is marked unverified or not verified. Plans and prices change; confirm them with Semrush before you decide.

99Visibility vs Semrush AI Visibility Toolkit: Overview

Semrush is a well-established SEO suite, and its AI Visibility Toolkit adds AI tracking beside it. The toolkit's pricing page lists a Base plan at $99/mo per domain, billed annually: 25 custom prompts tracked daily, one domain for brand analysis, and mentions from ChatGPT, Google AI, Gemini and Perplexity. If you already work in Semrush, that puts AI data next to the SEO data you have.

99Visibility is built for generative engine optimization and sold on its own. It audits ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Claude, checks each answer against your facts, checks whether AI crawlers can reach your site, and ends each audit with ranked fixes.

Key Differences

Platform coverage. The toolkit lists ChatGPT, Google AI, Gemini and Perplexity. Every paid 99Visibility plan asks all 6 platforms, Claude included. Each engine finds and cites pages its own way, and even AI Overviews and Gemini are separate Google products that Google says may return different links. Visibility on one is not visibility on the rest.

How it is priced. The toolkit is priced per domain, so each brand you track adds $99/mo. 99Visibility is priced per plan: 1 brand on Free, 1 brand on Starter, 3 brands on Growth and 10 brands on Pro. The toolkit's pricing page does not say whether it needs a Semrush subscription; confirm that with Semrush.

Limits. Each plan tracks a set number of keywords: Free 5, Starter 25, Growth 50 and Pro 100. Each keyword is asked on every platform in the plan, and nothing is billed as overage; a plan limit stops at the limit.

What 99Visibility checks

Every answer is read against the facts in your brand profile: price, founding year, location and features. Each flag carries a severity of critical, moderate or minor. A wrong price is moderate, and the fix it triggers, "AI quotes the wrong price for [brand]", is ranked critical because buyers act on a price.

On Free you see how many answers contradict your facts; what each flag says starts on Starter. When an audit finds a critical flag, we email you as the audit finishes. That is one alert per audit, not continuous monitoring, and on Starter and up you can schedule weekly or monthly re-audits.

Every plan, Free included, checks whether 18 AI crawlers can reach your site: robots.txt for each one, and a request as each of the 16 that fetch pages to see what your firewall answers. Each finding quotes what the vendor says a block costs, so a ChatGPT search block ranks critical and a training-only block ranks low.

What happens after the audit

Every audit ends in a ranked fix list. Each fix has a title, the action, the reason, a priority from critical to low and an effort of about 30 minutes, 1-2 hours or 3+ hours. When robots.txt blocks OpenAI's search crawler, the fix reads "ChatGPT search cannot see your site — OAI-SearchBot is blocked in robots.txt": critical, about 30 minutes, with the line in your file that causes it.

The fixes are subtractive and sourced: remove a crawler block, a stray snippet control or a wrong fact. The list never tells you to add schema or rewrite pages to get cited, because the evidence does not support it. On Starter ($49/mo) and up, each fix also has a step-by-step guide.

Pricing Comparison

The 3 brands row is our arithmetic from Semrush's per-domain price. If you already pay for Semrush and plan to keep it, the toolkit builds on what you have. If AI visibility is the job and you run more than one brand, a per-domain price adds up; confirm Semrush's current prices with them before you compare.

Who Should Choose 99Visibility?

Choose 99Visibility if AI visibility is your main concern and you want ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Claude in one audit, with fixes.

Choose it if you track several brands, if you do not already use Semrush, or if you need to know whether what AI says about you is true.

Choose Semrush's AI Visibility Toolkit if you already work in Semrush and want AI mentions on ChatGPT, Google AI, Gemini and Perplexity next to your SEO data.
