RankPrompt
RankPrompt is a platform built for “Answer Engine Optimization” (AEO) that helps businesses and marketers measure, track, and improve how often and how prominently their brand appears in answers generated by major AI assistants and large-language-model tools (like ChatGPT, Google Gemini, Perplexity, Grok, and others). RankPrompt lets you scan real user prompts to see whether these assistants mention your brand (or competitors’), then tracks your visibility over time across multiple platforms. It offers prompt-level insight, showing not only whether you appear, but under which questions/prompts, and how often. It also benchmarks your performance against competitors, flags visibility gaps, and gives actionable recommendations: for example, optimizing schema markup, improving citations, or content structure, all to increase your chances of being cited or recommended by AI. Through its trend-monitoring tools, you can track how visibility changes after content updates, PR efforts, and more.

tobecited
tobecited shows brands how they appear in AI assistants. We run your real buying questions through ChatGPT, Claude, Gemini and Perplexity, record who gets recommended and who gets cited, and compare you against the competitors that show up instead of you.
The result is not an abstract score. Every answer comes with the verbatim excerpt behind it, so you can see the exact sentence where a competitor was recommended in your place, and the gaps that explain it.
The first audit is free — no card, no sales call — and it puts every one of your questions to all four assistants. Paid runs add what the free one leaves out: the competitor breakdown behind each answer, and the fixes that close the gaps — llms.txt, structured data, page titles, FAQ blocks, written against your actual pages. Ongoing monitoring re-runs the same questions week over week, so you can see whether your visibility in AI answers is actually moving.

Lettertrace
Lettertrace is an open source AI visibility monitoring platform that measures how often Claude, ChatGPT, Gemini, and Google AI Overviews mention and recommend a brand. Users add the topics their buyers ask about, and the platform automatically generates natural prompt variations to monitor how AI assistants actually answer those questions. Every run becomes a datapoint, allowing teams to track visibility, prominence, sentiment, and share of voice per topic and model over time. Competitor benchmarking shows how often rival brands appear, which companies AI models recommend, and how a brand performs against each competitor. Reports turn raw AI answers into the metrics AEO and GEO teams need, including brand visibility, share of voice, sentiment, recommendations, and competitive performance. Scheduled monitoring can run daily or weekly to build actionable trend lines, while multi-model analysis makes it possible to compare results across answer engines side by side.

Babel42
Babel42 tracks whether AI assistants recommend your brand when a buyer asks them for a supplier.
Most tools in this space fire static prompts and count mentions. Babel42 builds AI buyer personas and sends each one through a complete buying journey: it asks follow-ups, compares options and narrows down the way a real customer does. What comes back is who got recommended at the point of decision, which sources the assistants read to get there, and why a rival won. Seven assistants are covered: ChatGPT, Claude, Perplexity, Gemini and Grok are shopped multi-turn, and Google's AI Overviews and AI Mode are probed per question.
Alongside it, Babel42 runs social listening across social, video, news, developer and question-and-answer communities, blogging and review sites, with AI scoring the sentiment of every post.
A free AI SEO audit is also available that checks whether AI crawlers can reach, render and quote your pages.
