The short answer
Otterly.AI and AthenaHQ are both AI visibility (AEO) trackers that monitor how a brand shows up in AI answers across ChatGPT, Perplexity, and Google AI Overviews. The honest split is entry cost versus engine breadth and enterprise depth. Otterly.AI is the cheaper, longer-running option: it launched in 2024, starts at $29/mo with a no-card 7-day trial, and covers four core engines out of the gate. AthenaHQ is the younger, broader platform: it launched out of Y Combinator’s Winter 2025 batch, starts at $295/mo for full paid access, but tracks 9 AI models including Grok and adds enterprise features (audit logs, multi-region, SOC 2 Type 2, a brand-claim discrepancy detector) that Otterly.AI does not publish. Note that SSO alone is not the dividing line: Otterly.AI does list Single Sign-on on its own custom Enterprise tier. Both vendors sit on thin G2 review bases (roughly 30 to 50 reviews each), and G2’s pages return a bot-blocked response on direct fetch, so the rating figures below are corroborated through search-indexed G2 listings and vendor-displayed badges rather than a first-hand page render.
If budget is the deciding factor, you want a real self-serve trial (7 days, no credit card) before paying anything, you value four core engines bundled into the cheapest paid tier, and you’d rather have flat, predictable per-tier pricing than a credit meter, Otterly.AI is the sharper pick at $29/mo Lite up to $489/mo Premium.
If you need to track 9 AI models including Grok, want built-in brand-claim and hallucination detection (Oracle), require published enterprise compliance (SAML SSO plus audit logs, multi-region, and a stated SOC 2 Type 2 certification) for a regulated buyer, and can absorb a $295/mo Starter price with no self-serve free trial, AthenaHQ’s higher floor is buying real breadth.

Vendor profile
Otterly.AI
Otterly.AI was founded in 2024 by Thomas Peham (CEO, formerly of Storyblok and Usersnap), Josef Trauner (CPO, founder of Usersnap), and Klaus-M. Schremser (CRO). Its own press coverage states a Vienna, Austria home base, though some secondary aggregators instead list Persenbeug, Austria, a discrepancy left unresolved rather than picked. Team size is reported around 12 employees, though this comes from third-party aggregator tracking rather than a company-published headcount, with estimates ranging from roughly 7 to 12 across late 2025 and mid-2026. The company states it reaches 30,000+ marketing professionals on its homepage, a company-reported usage figure, not an independently audited count, and one that sits oddly next to its own About page, which cites 20,000 as of early 2026. Otterly.AI was named a 2025 Gartner Cool Vendor for AI in Marketing (one of five vendors recognized, per its own GlobeNewswire release), and its About page states it has been named a G2 High Performer for Answer Engine Optimization Tools. On OMR Reviews it currently carries Leader badges for Brand Management and Generative Engine Optimization (Q3/26) plus a Top Rated badge for Generative Engine Optimization; it also displays a Tekpon “Top SEO Software Q4 2025” badge, which we could not confirm on Tekpon’s own site. Its core plans track four AI engines (ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot); Google AI Mode, Google Gemini, and Claude are available only as paid add-ons on the Standard and Premium tiers. Funding status is reported as bootstrapped in third-party coverage, a claim not independently confirmed against Crunchbase or PitchBook.

AthenaHQ
AthenaHQ is a Y Combinator-backed company (Winter 2025 batch) headquartered in San Francisco, California, founded by Andrew Yan (Co-Founder and CEO) and Alan Yao (Co-Founder; described elsewhere as CTO, a title YC’s profile does not list). YC’s profile says Yan previously worked on Google Search’s information acquisition team and at DeepMind’s generative media team; the widely repeated “former Google Search product manager” phrasing is a paraphrase we could not confirm. YC’s own profile lists a 2025 founding year, though some secondary trackers cite 2024; YC’s page is treated as primary. Team size is listed at 12 employees on the YC profile, comparable to Otterly.AI’s. Its pricing page markets coverage across 9 AI models on the paid Starter tier, including Grok, which Otterly.AI does not track at any tier, versus 5 platforms on the free Essential tier; its homepage phrases the same claim as “8+ AI platforms.” AthenaHQ’s differentiated features include an “Oracle” discrepancy detector for brand-claim and hallucination checks, an Athena Citation Engine (ACE), and Enterprise-only SAML SSO, audit logs, and multi-region support. Of those, only SSO has an Otterly.AI counterpart (on Otterly’s custom Enterprise tier); the rest Otterly.AI does not document. AthenaHQ’s homepage also states SOC 2 Type 2 certification and GDPR compliance. A reported G2 Spring 2026 High Performer badge in the Answer Engine Optimization category could not be confirmed: the secondary source originally cited for it no longer displays the claim, and G2’s own pages block automated fetches, so treat the badge as unverified. A G2 reviewer highlighted the product’s “Action Center” as its standout differentiator against tools that show data without a next step; that quote also comes from a search snippet rather than a rendered G2 page.

Pricing: what you'll actually pay
Both vendors publish self-serve pricing pages, verified as of July 2026. AthenaHQ’s paid entry price is roughly 10x Otterly.AI’s, though AthenaHQ’s free Essential tier gives limited ongoing access at no cost. Enterprise pricing on both sides is custom and not itemized.
| Otterly.AI | AthenaHQ | |
|---|---|---|
| Starting price | $29/mo (Lite, $25/mo annual), 15 prompts, 4 engines | $295/mo (Starter, 3,600 credits/$300 value), 9 models |
| Free tier | None ongoing; 7-day free trial only, no credit card | Essential: $25 in credits (300 credits), 5 platforms, unlimited members |
| Mid tier | $189/mo (Standard, $160/mo annual), 100 prompts, API 2,000 req/mo | Not itemized on the live pricing page; only Essential (free) and Starter ($295) are published (secondary sources cite unmatched $270/mo and $545/mo tiers) |
| Top self-serve tier | $489/mo (Premium, $422/mo annual), 400 prompts, 10,000 GEO audits/mo | Not published; Enterprise is custom/demo-gated (Knowledge Base, ACE, SSO, audit logs) |
| Add-on / extra cost | +100 prompts for $99/mo; extra engines $9 to $439/mo depending on tier | API access and extra credits billed separately on Starter, not itemized |
| Enterprise pricing | Custom, includes SSO, dedicated support, quarterly health checks | Custom/demo-gated; Knowledge Base, Oracle, ACE, SSO, audit logs, multi-region |
Capability comparison
Both tools do the same core job: track how a brand shows up across AI answer engines. The gaps show up in how many engines each covers, whether the product stops at monitoring or adds brand-claim/hallucination detection, and how each vendor handles enterprise compliance. Otterly.AI wins on entry-tier price and trial friction; AthenaHQ wins on engine ceiling and enterprise-grade features.
| Service | Otterly.AI | AthenaHQ |
|---|---|---|
| Engines tracked (cheapest paid tier) | 4 engines on $29 Lite (ChatGPT, AI Overviews, Perplexity, Copilot) | 9 models on $295 Starter; the free Essential tier covers 5 (ChatGPT, Perplexity, AI Overviews, Gemini, Claude) |
| Engines tracked (top tier) | Up to 7 with paid add-ons (AI Mode, Gemini, Claude); no Grok | 9 models incl. Grok, marketed on Starter and Enterprise |

| Unlimited team seats | ✓ (every paid tier) | ✓ (stated on free Essential tier; not itemized on Starter/Enterprise) |
| Free trial / free plan | 7-day free trial, no credit card; no ongoing free plan | No self-serve trial; ongoing Essential tier is free but credit-limited ($25/300 credits) |
Decision matrix - who fits which side
| Criterion | Otterly.AI | AthenaHQ |
|---|---|---|
| Tightest budget, lowest paid entry cost | ✓ | ✕ |
| Need the widest AI-engine ceiling (incl. Grok) | ✕ | ✓ |
| Want a frictionless self-serve trial before paying | ✓ | ✕ |
| Want an ongoing free tier (even if capped) | ✕ | ✓ |
| Need enterprise compliance (audit logs, multi-region, SOC 2) | ~ | ✓ |
| Need built-in hallucination / brand-claim detection | ✕ | ✓ |
| Want unlimited team seats at the cheapest tier | ✓ | ~ |
| Longer public track record (founded earlier) | ✓ | ✕ |
| Want third-party analyst recognition (e.g., Gartner) | ✓ | ✕ |

Both vendors’ G2 pages returned a bot-blocked response (HTTP 403) on direct fetch, so every rating figure above comes from G2’s search-indexed listings rather than a rendered page. Otterly.AI’s 4.8/5 is corroborated in three places: G2’s indexed listing, the badge Otterly.AI displays on its own homepage, and OMR Reviews, which shows 4.8/5 across 54 reviews on a separate review base. Its G2 review count is the one soft number, listed as 41 on the product page and 52 on the seller page, so treat it as roughly 40 to 50. AthenaHQ’s G2 seller listing shows 4.9/5 across 34 reviews; earlier snapshots in the low 30s suggest the base is still growing rather than that the figure is wrong. Given how young this category is (Otterly.AI founded 2024, AthenaHQ founded 2025), a thin review base on either side is expected rather than a red flag by itself. The honest read is that a G2-star comparison alone should not decide between these two; the engine-coverage and compliance gaps matter more for most buying decisions. For a wider view of the category, see our roundup of the best AI visibility tools .
Both tools’ data is sourced from publicly available information as of July 2026. Pricing, tiers, engine counts, and named customers were read directly off each vendor’s live homepage and pricing page. Direct G2 review-page fetches were bot-blocked (HTTP 403) at write time; G2 ratings and counts come from G2’s search-indexed listings, cross-checked against vendor-displayed badges and OMR Reviews where possible, and should be re-checked live before relying on them. Team size, founding year, HQ, funding status, and AthenaHQ’s reported G2 badge are flagged in-text where sources conflict or could not be confirmed, rather than resolved to a single number. This comparison is independent; we take no affiliate or referral fees from either vendor.
