Every price and limit attributed to another vendor below was read from that vendor's own public pricing page on 11 August 2026, and each is linked so you can check it yourself. Pricing in this category changes often. If you are reading this well after that date, treat the figures as a starting point and verify before deciding. Re-check competitor pricing quarterly, or whenever a vendor announces a pricing change.
What each publishes
Otterly.ai publishes four tiers on its pricing page. As read on 11 August 2026: Lite at $29 per month for 15 search prompts across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, with unlimited team members, daily tracking, one workspace, three recommendations per week and 1,000 GEO audits per month. Standard at $189 per month for 100 prompts, adding Claude, Google AI Mode and Gemini as add-ons, with unlimited workspaces and recommendations, 5,000 GEO URL audits, 2,000 API requests and 2,000 MCP requests per month. Premium at $489 per month for 400 prompts with 10,000 audits, 5,000 API requests and 1 million agent analytics events. Enterprise is custom, stated as starting from $1,000 per month. Annual billing is stated to save 15%, and extra prompts and individual engines are available as add-ons.
IndexHalo publishes IndexHalo Professional at EUR 79 per month and IndexHalo Agency at EUR 299 per month, with Enterprise arranged directly. Its published limits are domains, crawled pages per month, OCR documents per month, crawl depth and snapshot history.
A note on currency. IndexHalo prices in euro and the vendors below price in US dollars. The comparisons here do not convert between them, because the rate moves and a converted figure would be wrong by the time you read it. Compare the number against your own budget in your own currency.
Otterly publishes its quotas in more granular detail than most vendors in this category, including API and MCP request counts. That transparency is genuinely useful when you are trying to work out whether a tier will actually cover your usage, and it is worth acknowledging.
The two products meter different things
Comparing the headline prices directly is misleading, because the unit of work differs.
Otterly meters search prompts: the questions you track across engines. That is the natural unit for a visibility monitor, and if prompt tracking is what you need, its per-prompt economics are transparent and competitive.
IndexHalo meters pages and documents analysed, plus domains monitored. That reflects a product whose primary work is crawling and analysing content rather than polling engines. Both products also do some of what the other does — Otterly publishes GEO audit quotas, IndexHalo runs prompt sweeps — but the metering tells you where each one's centre of gravity sits.
The practical consequence: if your query set is large and your site is small, prompt metering will suit you. If your site is large and the question is why its content is not being cited, page metering will.
Where Otterly is the better choice
Entry price. $29 per month is the lowest credible entry point in this category. If budget is the binding constraint, that is decisive and no amount of feature comparison changes it.
Published API and MCP quotas. Stating 2,000 API and 2,000 MCP requests per month at Standard is concrete and checkable. If you intend to integrate programmatically, that specificity is worth a lot at evaluation time.
Granular add-ons. Being able to buy individual engines and extra prompts lets you shape a plan around a specific need rather than upgrading a whole tier to unlock one thing.
Where IndexHalo differs
Document and pre-publication analysis. Uploaded documents, including image-only scanned PDFs run through OCR, can be analysed before publication. We did not find this described on Otterly's public pages.
Crawler access resolution with the deciding rule. Fifteen AI user-agents resolved against a live robots.txt, each verdict traced to the rule that produced it — free and without signup in the access checker.
Evidence classing and drill-down. Findings labelled measured, observed, modelled or unknown, with any metric traceable to the raw archived answer behind it.
Working out which unit fits you
Because these two products meter different things, the honest way to compare cost is to price your own actual workload rather than the headline tiers.
Write down two numbers before you look at any pricing page. First, how many distinct questions you genuinely need tracked — not how many you could imagine, but how many you would actually read the results for. Most teams overestimate this substantially, and a focused set of twenty well-chosen questions is more useful than two hundred that nobody reviews. Second, how many pages and documents you need analysed each month, including anything that only exists as a PDF.
If the first number is large and the second is near zero, prompt metering is the right shape and Otterly's economics will likely favour it. If the second number is large — a substantial content estate, a document library, regular publishing — page metering will be closer to how you actually consume the product. If both are large you are looking at the upper tiers of either, and the decision should turn on the drill-down and confidence-interval tests rather than on price.
What we could not verify
We read Otterly's public pricing page and nothing more. We have not run a paid trial, tested its sampling methodology, or examined whether its reported figures carry confidence intervals. This page makes no claim about the accuracy of its measurements, because we have not measured them.
One thing worth noting fairly: "GEO audits per month" appears prominently in Otterly's published quotas, which suggests content auditing is part of its product. We could not determine from public pages what that audit covers, so we are not claiming its scope is narrower or broader than ours. If that capability matters to your decision, ask them directly rather than relying on this page.
IndexHalo published this page, and IndexHalo is one of the products being compared. Read it with that in mind. We have tried to make it useful by linking every competitor claim to its source, stating plainly where a competitor is the better choice, and describing what we could not verify rather than filling the gap with a guess. If you find something here that is out of date or wrong, tell us and we will correct it.

Common questions
Which is cheaper to start with?+
Otterly, clearly, on published prices. Its Lite tier is $29 per month for 15 search prompts across four engines. IndexHalo Professional is EUR 79 per month. If your requirement is basic prompt tracking on a small budget, Otterly's entry tier is the lower-cost option and we would say so to anyone asking.
What does Otterly include at the entry tier?+
As published on its pricing page on 11 August 2026: 15 search prompts, tracking across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, unlimited team members, daily tracking, one workspace, three recommendations per week and 1,000 GEO audits per month.
Does Otterly have an API?+
Its published Standard tier states 2,000 API requests and 2,000 MCP requests per month, rising at Premium. If programmatic access or MCP integration is a requirement, those are concrete published numbers worth weighing.
What does IndexHalo do that Otterly does not describe?+
The clearest difference we found is document analysis: IndexHalo analyses uploaded documents including image-only scanned PDFs through OCR, so unpublished content can be checked before release. We did not find an equivalent described on Otterly's public pages.
Which should a small team choose?+
If you want to know how often your brand appears in AI answers and you want the cheapest credible way to start, Otterly's Lite tier is a reasonable entry point. If your problem is that you do not know why your content is not being cited, the diagnostic work is where IndexHalo is aimed. Starting with our free tools costs nothing and will tell you which problem you actually have.
