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.

Knownwise
Knownwise helps brands and marketing teams track how ChatGPT, Claude, Gemini, and Perplexity answer buyer questions about their category. Its dashboard records brand mentions, competitor recommendations, answer position, sentiment, and cited sources, making it possible to compare visibility across AI assistants over time. Users can run a free site audit that scores AI readiness and highlights issues affecting how assistants read and cite a website. Paid plans schedule recurring answer tracking across all four assistants, with plan-based prompt and answer limits, alerts, and analytics connections. On eligible plans, an agent can prepare website fixes as GitHub pull requests for review; users approve changes before they go live. The service also offers a free brand check and audit for evaluating AI search visibility.

GEO Checker
GEO Checker is an AI search visibility tool that shows how your brand appears in real AI answers. Add your website, the competitors you care about, and the real questions buyers ask before they choose. GEO Checker runs those prompts across ChatGPT, Gemini, Claude, Grok, Perplexity, DeepSeek, Google AI, Kimi and Doubao from the browser sessions where you are already signed in, so there are no API keys and no copy and paste. It then measures brand mentions, ChatGPT citations, Perplexity results, cited sources and competitor share of voice, shows a clear leaderboard and tracks your AI visibility over time. Use the gaps to decide which content to create or improve next and turn AI visibility into new customers. The core workflow is free and privacy-focused, and it runs as a Chrome extension. Free tools include an llms.txt checker and a GEO checklist. Paid plans are listed on the pricing page. The dashboard shows average visibility, runs, prompts and citation sources.
