What Semrush AI toolkit does and costs
The Semrush AI Visibility Toolkit (or AI SEO Toolkit) adds AI search monitoring, prompt research and brand sentiment to Semrush. Per Semrush's pricing and knowledge base on October 29, 2026, it costs $99/month per domain billed annually and tracks 25 custom prompts daily across 5 platforms: ChatGPT, Google AI Overviews, Google AI Mode, Perplexity and Gemini.
It includes an AI Visibility Score, competitor and prompt research, an AI search site audit for crawler blockers, and weekly Brand Performance reports with share of voice and sentiment. Semrush One plans include 50 to 200 prompts. Semrush Enterprise AIO is custom-priced with unlimited prompts across 9 engines: ChatGPT, Google AI Overviews, AI Mode, Perplexity, Copilot, Grok, Gemini, Claude and DeepSeek.
Why people look for a Semrush AI toolkit alternative
Consider per-domain billing, prompt limits and trial availability when comparing tools. Per Semrush's pricing on October 29, 2026, an extra domain costs +$99/month and +50 prompts costs $60/month. There is no free trial, though Semrush's free plan has limited AI visibility features. Finally, teams practicing generative engine optimization often want the exact title and snippet ChatGPT's search index stores for their URLs, not a weekly share-of-voice report.

The alternatives
Each alternative approaches AI search differently, from page-level ChatGPT search checks to multi-engine prompt tracking.
FoundByChat
FoundByChat shows site owners when ChatGPT's search finds, cites or rewrites their pages. Add your website and customer questions, and FoundByChat asks ChatGPT with web search on every 2 hours as a user in the United States (English) or the Netherlands (Dutch). Every check records whether ChatGPT's search found your page ("Found"), cited it ("Cited"), and its usual search result position.
It lists your "Pages in ChatGPT's index" with the title and snippet ChatGPT keeps, and emails you on "New in the index", "Snippet changed", or "No search results" three checks in a row. It is free to start with Google or an email link (no password or credit card), has an English and Dutch interface, and includes API keys. FoundByChat checks ChatGPT search only: not Google AI Overviews, AI Mode, Gemini, Perplexity, Claude or Copilot, and no competitor tracking or visibility score. A free GEO audit (5 audits/day, no account) fetches your page with the OAI-SearchBot user agent, rebuilds the ~200-character snippet, and scores it out of 100.
Ahrefs Brand Radar
Ahrefs Brand Radar splits AI tracking into custom prompts and a pre-built index, per Ahrefs' pricing on October 29, 2026. Custom prompts come with paid Ahrefs plans: Lite at $129/month ($1,290/year, 150 checks/month), Standard ($249/month, 300 checks), and Advanced ($449/month, 600 checks). The AI Visibility Index add-on costs $199/month per platform or $699/month for all, with its question sets re-tested monthly while custom prompts run daily, weekly or monthly across Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot (plus Claude on custom prompts), with no free trial.

When Semrush AI toolkit is still the better pick
Semrush AI Visibility Toolkit fits single-domain Semrush users wanting their AI Visibility Score, weekly Brand Performance sentiment, prompt research and crawler blocker audit on one bill. For enterprises needing unlimited prompts across 9 engines (including Grok and DeepSeek), Semrush Enterprise AIO fits.
How to choose
- List the engines you act on. If you only act on ChatGPT search results and snippets, paying for 5 or 9 engines adds cost.
- Count your domains and prompts. Semrush charges $99/month per domain billed annually; SE Visible includes 5 projects on Basic.
- Decide on ChatGPT page checks. Use FoundByChat (free to start, ChatGPT search only) to see when ChatGPT finds, cites or rewrites your pages.
- Test for crawler blockers. Run the free GEO audit to check robots.txt for OAI-SearchBot, GPTBot and ChatGPT-User and check whether text is present in the HTML without JavaScript.
