Profound is the category-defining AI search optimization tool, tracking brand mentions in AI answers across engines with agents that act on gaps. The platform covers up to 9 engines on Enterprise, offers Prompt Volumes data, and carries SOC 2 compliance on Enterprise plans, which suits large enterprises running serious GEO programs.
Pricing is the messiest in the category: guides cite 99 dollars a month for a ChatGPT-only plan, 399 dollars a month for Growth, and custom Enterprise pricing, with a free 7-day trial and 50 prompts on the trial. Confirm the current plan on the vendor pricing page before budgeting, since the entry price depends heavily on engines covered. For a large enterprise that wants one suite with agents that act, Profound is the strongest pick.
What we like- Category leader by scale
- Up to 9 engines on Enterprise
- Agents that act on gaps
- SOC 2 on Enterprise
- Prompt Volumes data
Watch out for- Pricing conflicts across guides: 99 dollars a month ChatGPT-only, 399 dollars a month Growth, Enterprise custom
- 7-day trial only
- Enterprise focus

Otterly is the cheapest working AI search monitoring, from 29 dollars a month with 15 prompts on the Lite plan, 4 base engines, and an AEO audit included. The pricing is transparent, the tool is marketer-built, and it suits small teams and agencies that need real monitoring without an enterprise budget.
The limits are real: 15 prompts is small for a large brand, and Gemini, Google AI Mode, and Claude cost extra as add-ons, so the engine count on the entry plan is narrower than it first appears. Cost per prompt on the entry plan runs near 1.93 dollars a month. For a small team starting AI visibility tracking, Otterly is the best value pick.
What we like- Cheapest working monitoring
- 29 dollars a month entry
- 15 prompts on Lite
- 4 base engines
- AEO audit included
- Transparent pricing
Watch out for- Gemini, Google AI Mode, and Claude cost extra
- 15 prompts is small
- Marketer-built, less enterprise depth

Peec AI, based in Berlin, suits European agencies and multi-client teams with clean daily tracking, unlimited seats, and free pitch workspaces for agency sales. The Starter plan includes 50 prompts and 3 engines of your choice, with more engines as add-ons, and the tracking is deliberately monitoring-only, which keeps the interface clean.
Pricing conflicts across guides cite 85 euros a month and 95 dollars a month for the entry plan, so confirm the current rate and currency before budgeting. Peec offers no remediation, so fixing the gaps it finds needs another tool or manual work. For an agency that needs clean multi-client tracking, Peec is the best pick.
What we like- Clean daily tracking
- Unlimited seats
- Free pitch workspaces
- Berlin based
- 50 prompts and 3 engines on Starter
Watch out for- Pricing conflicts: 85 euros a month in one guide, 95 dollars a month in another
- Monitoring only, no remediation
- Extra engines are add-ons

Brandlight tracks brand mentions in AI answers for enterprise CMO organizations buying through sales, with strong logos and an ads and commerce roadmap. The CMO-focused reporting suits a marketing leadership team that needs brand visibility in AI answers presented for executive decisions.
Pricing is quote-only and not published, and depth is not publicly verifiable, so a buyer cannot compare Brandlight against rivals without a sales conversation. For an enterprise CMO team that buys through sales and wants executive reporting, Brandlight belongs on the shortlist. For a team that needs published pricing, Otterly or Peec is a better starting point.
What we like- Enterprise brand mention tracking
- Strong logos
- Ads and commerce roadmap
- CMO-focused reporting
Watch out for- Quote-only pricing, not published
- Depth not publicly verifiable
- Sales-led buying
- Enterprise focus

Evertune offers enterprise brand measurement at statistical scale, with model-level brand perception and share of voice, the biggest prompt samples in the category, and a published method. The Pro plan includes 100 samples per prompt and up to 100,000 prompts, which suits large advertisers that need statistically sound measurement rather than a small sample.
Pricing conflicts sharply across guides: 800 dollars a month for Pro in one source, 60 dollars a month billed annually in another, so confirm the current plan before budgeting. Evertune is measurement-first, and execution stays with you, so fixing gaps needs another tool. For a large advertiser that needs rigorous brand measurement, Evertune is the best pick.
What we like- Model-level brand perception and share of voice
- Biggest prompt samples in the category
- Published method
- 100 samples per prompt
Watch out for- Pricing conflicts: 800 dollars a month Pro in one guide, 60 dollars a month billed annually in another
- Measurement-first, execution stays with you

Goodie AI suits brands wanting agents and attribution in AI search, with tracking across major engines plus agents, MCP access, and revenue attribution that ties AI visibility to business results. The Explorer plan costs 399 dollars a month billed yearly in one guide, with up to 11 models on Enterprise, while another guide cites 295 dollars a month for Core with 110 prompts and one brand.
Confirm the current plan and prompt limits before budgeting, since the guides disagree on both price and prompts. Goodie is one of the few tools with attribution, which suits a team that needs to prove AI visibility drives revenue. For a brand focused on agentic commerce, Goodie is the best pick.
What we like- Tracks brand mentions in AI answers
- Agents and attribution
- Up to 11 models on Enterprise
- MCP access
- Revenue attribution
Watch out for- Pricing conflicts: 399 dollars a month billed yearly in one guide, 295 dollars a month in another

AthenaHQ suits self-serve teams wanting attribution plus broad engine coverage, with a free tier, Starter at 295 dollars a month with 3,600 credits at one credit per answer, 5 free engines and 11 on Starter, GA4 attribution, and a Citation Engine. The free tier lets a team test real tracking before paying, and the attribution features suit teams that need to prove ROI.
Starter pricing is high for a small team, credit-based pricing needs careful math to compare against prompt-based rivals, and execution is customer-operated with no bot-log analytics. For a team that wants optimization tools plus attribution and can use the credit volume, AthenaHQ is the best pick.

Rankscale offers many engines on a credit-based model, with 17-plus engines on every plan, credits that roll over, and white label from the Growth plan. The Essentials plan costs 17 dollars a month on yearly billing with 120 credits for up to 480 answers, while Pro is cited at 99 dollars a month with 1,200 credits, which makes Rankscale the cheapest way to cover many engines.
Credit math needs care, since credits and answers are not the same unit, and the vendor is newer than Profound or Peec. For a team that wants broad engine coverage at a low entry price and can manage credit math, Rankscale is the best value pick.
What we like- 17-plus engines on every plan
- Credit-based pricing
- Credits roll over
- White label from Growth
- Essentials from 17 dollars a month yearly
Watch out for- Credit math needs care: 120 credits for up to 480 answers on Essentials
- Pro cited at 99 dollars a month with 1,200 credits
- Newer vendor
How we chose
We compared the entry paid plan for each tool divided by the prompts it includes, since headline prices hide very different prompt limits: Otterly at 1.93 dollars per prompt, Goodie at 2.68 dollars, Peec near 1.78 euros, and Rankscale credit-based. We also weighted engines covered, since a low price per prompt only helps if the plan covers the engines your buyers use, and we flagged where guides disagree on price, since Profound, Evertune, Goodie, and Peec each carry conflicting published rates. We deliberately did not list Scrunch, which renders demo content about a fictional product on its homepage and must not be recommended.
What to check before you buy
Compare cost per prompt and engines covered, not just the monthly price, and check whether the engines your buyers use are included or cost extra, since Otterly charges extra for Gemini, AI Mode, and Claude. Confirm whether the tool tracks only or also fixes gaps, since Peec and Evertune are monitoring-only while Profound agents act on gaps. Check whether a free tier or trial covers your prompt volume, and treat any guarantee of AI citations with suspicion, since making a page easy to quote creates conditions for a citation but does not guarantee one. Finally, verify pricing on the vendor page before buying, since this category changes prices and plans frequently.
Frequently asked questions
What is AI search optimization?
AI search optimization tracks and improves how AI answers mention your brand, across ChatGPT, Gemini, Perplexity, Copilot, and AI Overviews, rather than just ranking in traditional search results.
Which AI search tool is cheapest?
Otterly is the cheapest working monitoring at 29 dollars a month, while Rankscale covers 17-plus engines from 17 dollars a month on yearly billing. AthenaHQ offers a free tier for testing.
Can these tools guarantee AI citations?
No. Making a page easy to quote, keeping facts current, and stating them plainly creates conditions for a citation, but does not guarantee one. Anyone selling that guarantee should be treated with suspicion.
Do I need to track many AI engines?
It depends on where your buyers ask questions. Cover ChatGPT, Gemini, Perplexity, and AI Overviews first, then add Copilot, Claude, and AI Mode if your buyers use them.
How do prompt limits affect pricing?
Entry plans include very different prompt counts, from 15 on Otterly Lite to 110 on Goodie Core, so cost per prompt varies widely. Compare prompts and engines included, not just the monthly price.
