Why search "Profound vs AthenaHQ vs Otterly"
This is the same 3-tier shape as the Peec version, with a sales-led enterprise vendor, a self-serve challenger and a budget entry, but swapping Peec for AthenaHQ. Buyers asking this combo have usually already evaluated Peec and disqualified it on per-model add-on pricing, and are now comparing AthenaHQ's broad model list against Profound's enterprise sales gate and Otterly's $29 cheap entry.
What surprises buyers in this combo: each vendor has a different cost-shock mode. Profound publishes no price between its free Trial plan and Enterprise, so the number arrives in the sales call. AthenaHQ meters every AI response as a credit, so the monthly figure follows your tracking volume. Otterly's $29 Lite caps at 15 prompts, and the engines beyond the base four are paid add-ons.
Truffle's fourth-option pitch: flat tiers ($69 / $189 / $399), 6 AI surfaces standard on every plan including Claude and Gemini, multi-brand from $69, hosted in Germany. Of the three vendors named here, none combines a published flat price with all six surfaces in the entry tier.
Profound — sells enterprise, sales-gated
Sells to enterprises, with Fortune 500 logos on their own site, SOC 2 Type II and HIPAA compliance, Prompt Volumes panel data (consumer-AI queries plus demographics) and a ChatGPT Shopping module. Built for enterprise procurement rather than self-serve evaluation.
What hurts: beyond the free Trial plan there is no self-serve path. That plan runs 10 prompts once on ChatGPT, with no history, no export and no API. Everything above it is Enterprise, priced on request, and their pricing page names no figure.
AthenaHQ — credit-metered, broad engine base
Credit-based platform co-founded by an ex-Google-Search and DeepMind engineer. Their Starter plan lists 11 models (ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, Claude, Copilot, Grok, DeepSeek, Meta AI, Mistral), the widest list of the four. A free Essential tier covers five of them with 300 credits.
What hurts: credit-based pricing makes the monthly cost variable, because every AI response burns a credit. Starter is $295 for 3,600 credits, and API access plus extra credits are add-ons billed on top of it.
Otterly.ai — cheap entry, per-prompt billing
Most accessible entry at $29/month Lite, with daily tracking, unlimited team members and strong citation intelligence. Their free trial needs no card, and their own pages give its length as 7 days in one place and 14 in another.
What hurts: Lite caps at 15 prompts on a single workspace. Standard ($189) adds unlimited workspaces. Base plans track 4 engines; Claude, Gemini and Google AI Mode are paid add-ons. Coverage beyond the base four is bought per engine, so a wider setup costs more than the tier price suggests.
Truffle — the flat-tier mid-market option
Why we sit between these three: Profound's price is a sales call, AthenaHQ's credit math moves with usage, Otterly's prompt cap tightens as you scale. Truffle ships flat $69 / $189 / $399 tiers with 6 AI surfaces standard on every plan (Claude + Gemini + ChatGPT + Perplexity + Google AI Mode + AIO/SERPs), multi-brand from $69 (2 brands at Starter, 15 at Pro/Agency), hosted in Germany.
Honest concession: we're smaller than Profound, and our surface list is shorter than AthenaHQ's (we ship 6, with no Meta AI, Grok or DeepSeek). No SOC 2 Type II yet. If those gaps are dealbreakers for your buyer, the right answer isn't us.

Questions, answered
What's the cheapest of the four?
Otterly.ai Lite at $29/month — capped at 15 prompts on a single brand. For real-volume tracking, Truffle Starter at $69 (2 brands, 25 prompts, 6 surfaces incl. Claude) is the better-value entry.
Which has the broadest engine base?
AthenaHQ lists 11 models on Starter (ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, Claude, Copilot, Grok, DeepSeek, Meta AI, Mistral) and five on its free Essential tier. Truffle ships 6 surfaces on every tier (ChatGPT, Claude Haiku, Gemini, Perplexity, Google AI Mode, AIO + SERPs Top-10). Profound's Trial plan covers ChatGPT alone, with up to 9 engines on Enterprise. Otterly's base is 4, and Claude, Gemini and AI Mode are paid add-ons.
Which one can I try without paying?
Checked on their own pages on 17 September 2026: AthenaHQ has a free Essential tier with 300 credits and five models. Otterly has a free trial without a card, given as 7 days in one place on their site and 14 in another. Profound has a free Trial plan with 10 prompts run once on ChatGPT. Truffle has no trial right now, and the free part is the visibility check, which runs without an account.
Best for agencies?
Truffle ($399 Pro/Agency = 15 brands, unlimited seats, API). Profound routes agencies through Enterprise, priced on request. AthenaHQ bills in credits rather than brands, so the cost follows how much you track. Otterly Standard ($189) already includes unlimited workspaces, with Premium ($489) above it.
Where is the data stored?
Truffle runs on Hetzner in Germany with daily encrypted backups, and says so on this page. Profound, AthenaHQ and Otterly name no hosting location on their pricing pages, so ask for their data-processing terms before you sign. Profound holds SOC 2 Type II, which procurement often accepts as a compensating control.
Pick by surprise tolerance
Each of the three named vendors has a different cost-surprise mode: the sales call, the credit meter, the prompt cap. Truffle's pitch is the absence of surprise, with flat tiers and all 6 surfaces included. Start with the free visibility check on your own domain, no account needed.
