Key takeaways
- Superlines works if you need real-UI data across a handful of engines and don't mind paying per-brand jumps (Starter at €79/mo caps at 3 engines and 50 prompts; the next brand tier jumps to €379). Its API lacks a documented spec, and third-party reviewers note thin G2 coverage.
- Promptwatch is the closest philosophical match and goes further: it pairs prompt tracking with AI crawler logs, content gap analysis, and Content Agents that actually draft and publish fixes to your CMS. Most tools on this list stop at reporting.
- AthenaHQ now has a genuine free tier (300 responses, 5 engines) and a $295/mo Starter, making it a reasonable AthenaHQ-vs-Superlines swap if you want more engines without an Enterprise contract.
- Otterly.AI is the budget pick at $29/mo if all you need is lightweight monitoring across 4 engines, no content generation attached.
- Profound and Scrunch sit at the high end: Profound is enterprise-only pricing with a deep AI Marketer layer, Scrunch's $250/mo Core is the priciest published self-serve entry point in the category.
Superlines pitches itself as AI search intelligence built on real user-interface data rather than API scrapes, which is a legitimate differentiator; a lot of competitors quietly rely on API outputs that don't always match what a person actually sees in ChatGPT or Gemini. But I've seen enough complaints piling up around Superlines to know it's not a universal fit. The Starter plan only lets you pick 3 of its 10+ engines, caps you at 50 prompts, and gives you a measly one month of history. Want more brands or longer history? You're jumping from €79/mo to €379/mo for Growth, with nothing sensible in between until the new €199 Pro tier (still only 2 months of history). The API is described by reviewers as "query-param style with no OpenAPI spec," which is a real pain if you're trying to build anything custom on top of it. And on G2, Superlines has essentially no review volume to go on.
If any of that sounds familiar, here's how the rest of the category stacks up.
Promptwatch
Promptwatch tracks ChatGPT, Gemini, Claude, Perplexity, Grok, DeepSeek, Copilot, Mistral, Meta Llama, Google AI Overviews, and AI Mode, and unlike Superlines it doesn't ration which engines you get by tier. Even the Essential plan ($95/mo) includes all of them, plus API and MCP access, visitor analytics, and content gap analysis. Professional ($245/mo) adds AI crawler logs and automated content generation, Business ($579/mo) adds city-level targeting and ChatGPT Shopping tracking.
The real difference versus Superlines (and most of this list) is what happens after you spot a problem. Promptwatch's Content Agents don't just flag that a page is losing citations, they draft the rewrite, run it past your brand book for tone, and publish straight to Webflow, Framer, or WordPress. Unified Actions turns all that data into a prioritized to-do list instead of a dashboard you have to interpret yourself. Agent Chat lets you ask plain-English questions about your visibility data and get an actual answer, in the dashboard or in Slack.
Promptwatch shipped server-log crawler analytics back in August 2025, before most competitors had anything like it, and it's one of the few tools in this category tracking Reddit and YouTube citations specifically, plus ChatGPT Shopping and Ads Radar for competitive ad intelligence. It's used by 1,840+ brands including Duolingo, Yelp, and Typeform, and sits at 4.7/5 on G2. Promptwatch's own research shows how fast this space moves: reddit.com's share of ChatGPT citations collapsed from roughly 4% to 0.5% in a single day in mid-August 2026 (see Promptwatch's Reddit citation drop report), which is exactly the kind of shift a monitoring-only tool would show you a week too late to act on.
Pricing comparison: Promptwatch's $95/mo Essential undercuts Scrunch's $250/mo Core and Semrush's $99/mo add-on tier on feature depth, while beating Superlines's €79/mo Starter on engine coverage (all engines vs. 3 picked).
Best for: teams who want one platform that both tells them why they're invisible and does something about it, without stitching together a separate content tool.
AthenaHQ
AthenaHQ has quietly become more accessible. It now has a free Essential plan (300 responses/mo, 5 engines: ChatGPT, Perplexity, AI Overviews, Gemini, Claude), and its Starter plan is $295/mo for 3,600 credits across 9 engines including Copilot and Grok. That's notably more generous engine-wise than Superlines's Starter, which locks you to 3 engines even at €79/mo.
Where AthenaHQ pulls ahead of Superlines is its Enterprise tier: an Advanced Content Optimization Agent, multi-country support, a Certified GEO/SEO Specialist on your account, and the newer Athena Citation Engine. It also integrates natively with Shopify, Webflow, GA4, and Search Console, which Superlines doesn't clearly advertise.
The catch is price scaling. $295/mo for Starter is a steep jump from the free tier, and API access is a paid add-on even at that level. If you need API from day one, factor that into the comparison.
Best for: brands that want a credible free tier to test the waters, then a mid-tier plan with broader engine coverage than Superlines offers at a similar price point.
Semrush
Semrush bolted AI visibility onto its existing SEO suite rather than building a dedicated GEO product, and it shows. The standalone AI Visibility Toolkit is $99/mo per domain (annual billing), but that only gets you 25 prompts for Prompt Tracking and 300 daily queries for AI Analysis, numbers that look thin against Superlines's 50 prompts at a similar price, let alone Promptwatch's unlimited-engine Essential tier.
One reviewer put it bluntly: "At $99/month, the toolkit faces high expectations, and many users feel it falls short in its current form." That tracks with what I'd expect from a toolkit built as an add-on rather than the core product. Where Semrush does make sense is if you're already paying for Semrush One for keyword research and site audits; bundling AI visibility in saves you managing a separate subscription, even if the AI-specific data is shallower than purpose-built tools.
Best for: existing Semrush customers who want basic AI visibility bundled in, not anyone shopping primarily for GEO depth.
Otterly.AI
Otterly is the cheapest credible option in this category, full stop. Lite is $29/mo for 15 prompts across 4 engines (ChatGPT, AI Overviews, Perplexity, Copilot), with Claude, Gemini, and AI Mode available as paid add-ons. Standard at $189/mo bumps you to 100 prompts and adds API, MCP, and crawler analytics. It's a 2025 Gartner Cool Vendor, and unlimited team members are included even on Lite, which beats Superlines's unlimited-seats-but-pricier Starter.
The honest trade-off: Otterly is monitoring-only. There's no content generation beyond briefs, no automated publishing, nothing resembling Promptwatch's Content Agents. You're buying visibility into the problem, not a way to fix it.
Best for: small teams or solo marketers who want to see if AI visibility is even worth investing in before committing real budget.
Peec AI
Peec is close to Superlines in philosophy, both are multi-language, multi-model monitoring tools aimed at marketing teams rather than enterprise. Starter is €85/mo for 50 prompts across 3 models, Advanced at €425/mo adds multi-country tracking and a Looker Studio connector. Peec also has genuinely useful niche features Superlines lacks: AI Shopping/SKU-level tracking, an Ads Library that detects which competitors are bidding on your prompts, and fact-checking of AI-generated claims about your brand.
What Peec doesn't do is close the loop with content. It's explicitly insights-focused; Gap Analysis tells you where you're missing, but there's no CMS publishing or automated content drafting attached.
Best for: teams that want deeper AI-specific features (shopping, ads, fact-checking) than Superlines offers, but are fine handling content fixes elsewhere.
Profound
Profound is the enterprise end of this category. The free trial covers only 3 engines (ChatGPT, Gemini, AI Overviews) for 7 days, and there's no published mid-tier self-serve plan, everything beyond trial is custom Enterprise pricing. What you get at that level is substantial: up to 9 Answer Engines, unlimited AI Marketer credits, full API, SSO, SOC 2, and all-time history.
Reddit's r/aeo community consensus is that "Profound and Peec are probably the strongest if budget is not an issue," and a Statsig marketing lead is
