If you're reading this, you've probably noticed a shift: more of your customers are finding products through ChatGPT, Perplexity, and Claude than through traditional Google searches. The question used to be "where do I rank on Google?" Now it's "does AI even mention us?"

That's the gap Answer Engine Optimization (AEO) tools fill. They monitor how generative AI engines respond when prospects ask about your category — and whether your brand is named, recommended, or invisible.

There are now about a dozen credible AEO platforms. This guide compares the seven we consider serious contenders in 2026, ranked by engine coverage, content production, pricing transparency, and ideal customer fit.

This comparison was compiled by Citadex. We are one of the tools listed below. Judge accordingly — we've tried to write this fairly, pointing out where competitors are stronger than us, and where we honestly think we're better.

How we evaluated each tool

We scored each platform across five dimensions:

Engine coverage — How many AI engines are tracked? Just ChatGPT and Perplexity, or the full lineup?

What's measured — Just mentions? Or also citations, ranking position, sentiment, and competitor share of voice?

Content workflows — Does the platform help you fix visibility gaps, or only diagnose them?

Pricing clarity — Self-serve with public pricing, or sales-gated enterprise?

Ideal customer size — Startup, mid-market, or enterprise?

At-a-glance comparison

|---|---|---|---|---|

| Citadex | 8 (ChatGPT, Claude, Gemini, Perplexity, Copilot, DeepSeek, Grok, Meta AI) | Yes (integrated content engine) | Self-serve to mid-market | Cross-border brands; teams that want monitoring + content in one place |

The clearest divider is engine coverage. Most tools cover 3-5 engines focused on the Western market. If you sell to global audiences — especially in markets where DeepSeek or Grok matter — coverage matters more than you'd expect.

Detailed breakdown

1. Profound

Profound is the enterprise leader in AEO right now. They've raised significant funding, have an enterprise-grade dashboard, and are the go-to for Fortune 500 brand visibility teams.

Strengths: Polished dashboard. Strong support team. Robust competitive analysis. Good for stakeholders who need executive-friendly reporting.

Weaknesses: Sales-led pricing means a typical deal starts around $30K+/year. No built-in content generation — you diagnose with Profound, then write elsewhere. Engine coverage is solid for Western markets but skips DeepSeek and Grok.

Best for: Large brands with dedicated content teams who want monitoring depth and don't mind paying enterprise rates.

2. BrightEdge AI Search

BrightEdge is a traditional enterprise SEO platform that added an AEO module. If you already use BrightEdge for SEO, the AEO add-on is a natural extension.

Strengths: Integrates with existing SEO workflows. Familiar dashboard if you're a BrightEdge SEO customer. Content optimization tools are mature (because the parent product is mature SEO software).

Weaknesses: AEO module feels grafted onto the SEO product rather than purpose-built. Like Profound, pricing is sales-led and enterprise-tier. Cross-engine coverage is narrower than purpose-built AEO tools.

Best for: Companies already paying for BrightEdge SEO who want to add AEO without learning a new tool.

3. Otterly

Otterly is one of the cleanest self-serve AEO tools — fast onboarding, good UX, transparent pricing starting around $99/month.

Strengths: You can be up and running in 15 minutes. Solid Perplexity tracking. Reasonable price-to-feature ratio for mid-market.

Weaknesses: Smaller engine roster. No content generation — purely monitoring. Limited competitive intelligence depth.

Best for: Mid-market brands that want to start AEO monitoring without a six-figure commitment.

4. Peec AI

Peec AI is a newer European entrant with a strong focus on Perplexity and EU markets.

Strengths: Sharp Perplexity-specific insights. Compliance-friendly for EU customers. Founder-led, responsive team.

Weaknesses: Less developed dashboard than Profound or BrightEdge. Engine coverage is solid but not deep. No content engine.

Best for: EU-based brands or any team where Perplexity is the dominant AI engine they need to win.

5. Athena HQ

Athena is a newer player. Lean team, lean product. Good for getting started — light footprint, focused feature set.

Strengths: Genuinely affordable entry tier. Clean interface.

Weaknesses: Feature gaps compared to more mature tools. Smaller engine list. Roadmap-dependent if you want advanced features.

Best for: Early-stage SaaS founders dipping their toes into AEO.

6. Daydream

Daydream targets the indie hacker / solo founder crowd. Simple, focused, inexpensive.

Strengths: Cheap, fast to set up. Good for personal projects or solo SaaS.

Weaknesses: Limited to 3 engines. No competitive intelligence. Limited team features.

Best for: Solo founders who want a basic "am I being mentioned at all?" check.

7. Citadex

We'll be straight: we built Citadex because we couldn't find a tool that covered 8 AI engines (including Chinese-language and Grok), and that also included a content engine to actually fix the gaps it surfaced.

Strengths: Broadest engine coverage in this list — 8 engines including DeepSeek, Grok, and Meta AI. Built-in content generation, so you can identify a gap and generate publishable content in one workflow. Cross-border focus (especially useful if you're a brand selling globally or a Chinese brand expanding overseas). Self-serve from $99/mo, with mid-market tiers below most enterprise alternatives.

Weaknesses: Newer team — fewer enterprise integrations than Profound. Dashboard customization is still maturing. If your only target is one engine (say, only ChatGPT) and you have deep enterprise needs, Profound's depth may serve you better.

Best for: Brands selling across multiple regions, mid-market SaaS, cross-border companies, and teams that want monitoring + content in one place without enterprise sales cycles.

How to choose: 3 common scenarios

You're an enterprise brand with a content team in place → Profound or BrightEdge AI Search. You'll appreciate the depth and the executive reporting.

You're a mid-market SaaS, run a lean marketing team, and want to fix gaps yourself → Citadex or Otterly. Self-serve, fast setup, and Citadex's content engine becomes useful here.

You're a solo founder testing whether AEO matters at all → Daydream or Athena HQ. Low commitment, low cost, and you can graduate to a fuller tool later.

Frequently asked questions

Is AEO worth it for a small SaaS?

Yes, if your buyers are researching tools through AI. Even at $99/month, the ROI shows up quickly if you discover a single high-intent prompt where your competitor is being recommended and you're not.

Can I do AEO manually?

You can. Open ChatGPT, Perplexity, and Claude. Ask your category's top queries. Note where you appear and where you don't. The problem is repeating this weekly across 30-100 prompts and 5-8 engines — that's where tools earn their keep. See our guide to manual AI mention tracking.

Do these tools also generate content?

Only some. Citadex and BrightEdge have content generation built in. Profound, Otterly, and Peec AI are monitoring-only. If you want to fix what you measure, the content workflow matters.

Which engine matters most?

It depends on your audience. For tech-forward Western markets, Perplexity and ChatGPT lead. For Chinese-market or cross-border brands, DeepSeek matters more than most Western tools acknowledge. For X/Twitter-native communities, Grok signals matter.
