Quick Verdict
Both track your brand's visibility across AI answer engines, but they solve different problems.

The choice comes down to commitment level. HubSpot's tool is perfect for the "let me check if we show up in AI responses" crowd. Promptmonitor targets companies ready to treat answer engine optimization like they treat Google rankings — with dedicated tracking, regular reports, and a budget to match.

Feature Comparison
HubSpot AEO Grader covers the basics: mention frequency across ChatGPT, Perplexity, and Gemini, plus context analysis showing how your brand appears in responses. It's designed as a one-time audit tool that integrates with HubSpot's broader marketing platform if you're already a customer. The report shows where you're mentioned and whether the context is positive or negative. Promptmonitor covers 8+ LLMs including newer models like Grok and DeepSeek. But its standout feature is publisher contact extraction — when an AI cites a source that mentions your brand, you get the contact information to reach out directly. The platform also generates llms.txt files for your website and provides AI crawler analytics showing which bots are accessing your content. These are operational features you'd actually use month-to-month, not just nice-to-know metrics. The tracking depth differs significantly. HubSpot gives you a report you'll check occasionally. Promptmonitor positions itself as your ongoing AI visibility dashboard with unlimited team seats and regular monitoring. I switched to continuous tracking after realizing AI mentions change faster than traditional search rankings.
Pricing Comparison
HubSpot AEO Grader is completely free, which makes it the obvious choice for companies testing the AI visibility waters. No credit card required, no usage limits on the basic functionality. If you need more advanced features, you'd upgrade to HubSpot's full marketing platform, but the AEO Grader works standalone. Promptmonitor starts at $29/month for the Starter plan, jumping to $39/month for Growth and $129/month for Pro. The free tier exists but with significant limitations. For $29, you're paying for ongoing monitoring that HubSpot simply doesn't offer. Whether that's worth it depends on how seriously you're approaching answer engine optimization as a channel.
Best For
HubSpot AEO Grader works best for companies doing their first AI visibility check or those already using HubSpot's marketing tools. If you want to know "do we show up in ChatGPT responses?" without any ongoing commitment, this gives you that answer in five minutes. Marketing teams that need a quick audit for quarterly reviews will appreciate the simplicity. Promptmonitor is better for companies treating AI visibility as an ongoing SEO channel. The publisher contact extraction alone justifies the cost if you're actively building relationships with sites that AI models cite. Teams running dedicated AEO campaigns need the continuous tracking and multi-LLM coverage that HubSpot doesn't provide.
The Verdict
Start with HubSpot AEO Grader to understand your current AI visibility, then upgrade to Promptmonitor if you decide to invest seriously in answer engine optimization. Most companies will find the free HubSpot tool sufficient for initial assessment, but once you're tracking AI mentions monthly and reaching out to publishers, Promptmonitor's $29 starter plan becomes essential. Try HubSpot's free audit first — if the results surprise you, sign up for Promptmonitor's trial to see the ongoing tracking in action.

For features, promptmonitor leads. On a budget, go with hubspot-aeo-grader.
