The short answer
Our rating: 3.5 out of 5.
Otterly.ai is the cheapest credible AEO tracker on the market, and that is exactly the role to buy it for. At $29/mo (about $25/mo billed annually) you get 15 tracked prompts across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, which is enough to prove whether AI search visibility deserves real budget. The limits are just as clear: 15 prompts is a narrow window, Google Gemini and Google AI Mode cost extra as paid add-ons ($9 to $149/mo each depending on plan), and there are no agency-style multi-brand economics. Small teams running their first tracking program will get their money's worth. Agencies and multi-brand teams should go straight to Peec AI, and enterprises to Profound. For the full landscape, see our guide to the best AEO tools.
A note on methodology before we go further: this review is based on research of Otterly.ai's public documentation, pricing, and third-party sources as of July 2026, not a hands-on trial. We run our own daily client tracking on a competing platform, so we know this category from the inside, and we have flagged clearly where we are reporting the vendor's claims rather than our own testing.
What Otterly.ai does
Otterly.ai is AEO tracking software: it runs a set of prompts you define across AI answer engines on a schedule, then reports whether your brand was mentioned, whether your pages were cited as sources, and how you compare against competitors on the same questions. That is the core job of any AEO monitoring tool, and it solves a real blind spot, because AI-influenced buyers are invisible in normal analytics. Someone who reads about you in ChatGPT and converts the next day shows up as direct traffic, and without a tracker you cannot tell whether the engines recommend you or hand the answer to a rival.
In Otterly's case, the base product covers four engines: ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot. It presents results in a clean, approachable interface that reviewers consistently describe as easy to start with, which matches its positioning as the entry-level option. Google Gemini and Google AI Mode tracking exist in the product but sit behind paid add-ons rather than being bundled in, which matters more than it first appears; we will come back to that.
The strategic reason to track citations at all, with any aeo tool, is that most of your AI visibility is not decided on your own website.
That is why any tracker you buy, Otterly included, is only useful if you act on the source data: find which third-party pages the engines trust, and go earn a presence on them.
Otterly.ai pricing
Prices in this category move quickly, so treat these numbers as a mid-2026 snapshot and confirm with the vendor before buying.
| Plan | Monthly | Annual (effective /mo) | Tracked prompts |
|---|---|---|---|
| Lite | $29/mo | ~$25/mo | 15 |
| Standard | $189/mo | ~$160/mo | 100 |
| Premium | $489/mo | ~$422/mo | 400 |
Two things stand out in that table. First, the jump from Lite to Standard is steep: $29 to $189 is more than a 6x price increase to go from 15 prompts to 100. There is no in-between tier, so the moment 15 prompts stops being enough, your bill changes character. Second, the per-prompt economics actually favor the top tier: Lite works out to roughly $1.93 per tracked prompt per month, Standard to about $1.89, and Premium to about $1.22. The headline "cheap" tier is, per prompt, the most expensive way to use the product. That is normal SaaS pricing logic, but worth knowing before you anchor on $29.
The add-ons: what full coverage really costs
The bigger caveat is engine coverage. Google Gemini and Google AI Mode are paid add-ons priced at roughly $9 to $149/mo each, scaling with your plan tier. So the real price of tracking all six engines Otterly can reach is the base price plus two add-on fees. On the Lite plan that is a modest bump; on Premium, with both add-ons at the top of the range, the all-in cost can approach $787/mo. At that point you are no longer shopping in the budget aisle, and platforms that bundle those engines into the base price deserve a look.
What Otterly.ai is good at
- Lowest credible entry price. At $29/mo, no other established aeo tracker gets you started cheaper. It makes the business case conversation easy: run it for a quarter, show the citation data, then decide whether AI visibility deserves a bigger line item.
- Transparent, self-serve pricing. Every number is on the pricing page, add-ons included, and you can start without a sales call. Competitors have since published entry tiers of their own, but few are as explicit about what each add-on costs.
- Covers the engines most buyers actually meet first. ChatGPT, Google AI Overviews, Perplexity, and Copilot in the base plan is a sensible default set for a first tracking program.
- Approachable for non-specialists. The product is positioned, and generally described by third-party reviewers, as easy to set up and read, which suits marketing generalists who do not want an enterprise dashboard.
- Annual discount is meaningful. Effective monthly prices of roughly $25, $160, and $422 knock a useful margin off if you are confident you will keep tracking.
Where Otterly.ai falls short
Every point here is grounded in the published pricing and packaging, not in speculation about product quality.
- 15 prompts on Lite is a narrow window. A serious prompt set covers your brand, your category, and your competitors across the questions buyers actually ask. Most brands need 30 to 100 prompts to do that properly, so Lite works as a proof of concept and little more.
- Google engines are paid add-ons. Gemini and Google AI Mode at $9 to $149/mo each means the advertised price is not the price of full coverage. Given how much AI search activity flows through Google surfaces, many teams will want at least one of these, and the add-on math changes the comparison against rivals that bundle them.
- A steep cliff between tiers. There is nothing between $29 and $189. When you outgrow 15 prompts, and most teams do quickly, your spend roughly 6.5x's in one step.
- No agency economics. There are no advertised multi-brand or unlimited-seat plans of the kind agency-focused platforms lead with. Tracking several brands means stacking prompt allowances, which erodes the price advantage that is Otterly's main draw.
- Claude is not in the advertised base coverage. If your buyers live in Claude, confirm coverage with the vendor before committing.
| Good at | Falls short |
|---|---|
| Cheapest credible entry to AEO tracking ($29/mo) | Only 15 prompts on the entry tier |
| Transparent self-serve pricing, no sales call | Gemini and AI Mode cost $9 to $149/mo each, extra |
| Sensible default engine set for a first program | Full six-engine coverage can approach ~$787/mo on Premium |
| Easy for non-specialists to run | No mid-tier between $29 and $189 |
| Meaningful annual discount (~$25/$160/$422 effective) | No agency or multi-brand plan economics |
Who should use Otterly.ai (and who should not)
Buy it if:
- You are a small team or solo marketer making your first foray into AEO tracking and need the lowest-risk way in.
- You need to prove the concept internally: three months of Lite costs less than one month of most competitors, and the citation data it produces is exactly the evidence a budget conversation needs.
- Your priority engines are ChatGPT, AI Overviews, Perplexity, and Copilot, and you can live without Gemini and AI Mode for now, or are happy paying the smaller entry-tier add-on fees.
Look elsewhere if:
- You are an agency or track multiple brands. The prompt allowances and lack of multi-brand plans make the economics work against you fast; Peec AI's agency tiers with unlimited seats are built for exactly this.
- You need all six engines including Gemini and AI Mode as table stakes. Price the add-ons honestly and compare the all-in number, not the headline.
- You are an enterprise with stakeholders, procurement, and scale requirements. That is Profound's territory.
Otterly.ai vs the alternatives
The short version, with the full comparison in our best AEO tools guide:
- Otterly.ai vs Peec AI. Peec starts at $95/mo for 50 prompts and includes ChatGPT, Gemini, Claude, Perplexity, Google AI Mode, and Copilot with no engine add-on fees, plus unlimited seats and agency plans from $245/mo. Otterly wins on absolute entry price; Peec wins on included coverage, seats, and multi-brand economics. Once you add Otterly's Google add-ons, the price gap narrows enough that most growing teams should compare the two directly. Our full Peec AI review covers it in depth, including our own hands-on use.
- Otterly.ai vs Profound. Different leagues, despite closer headline prices. Profound publishes a $99/mo Starter tier, but it tracks ChatGPT only, and its real product sits in a custom-quoted Enterprise tier. If you are choosing between these two, one of you is in the wrong evaluation.
- Otterly.ai vs doing it free. If even $29/mo is not yet justified, you can run your priority prompts manually across the engines and log results in a spreadsheet. Our guide to free AEO tools covers how far that gets you, and our walkthrough on checking whether ChatGPT recommends your brand is the ten-minute version.
How we evaluate AEO tracking software
AEO Labs runs AI citation tracking daily for client brands across ChatGPT, Perplexity, Gemini, AI Overviews, and Copilot, so we evaluate every aeo monitoring tool against the jobs that work actually involves: prompt coverage per dollar, which engines are included versus add-ons, whether the tool tracks the source URLs behind answers and not just brand mentions, and whether the plan structure fits single-brand or multi-brand work. For this review we did not run a hands-on Otterly trial; pricing, tiers, and engine coverage were verified against vendor documentation and third-party sources in July 2026, and anything beyond those verified facts is flagged as such. If you are new to the discipline itself, start with what Answer Engine Optimization is.
Watch: understand AEO before you buy a tracker
Before you spend even $29/mo, it is worth being clear on what the tool is measuring. This short explainer from Ahrefs covers what Answer Engine Optimization is and why the citation layer matters.
Key takeaways
- Otterly.ai is the budget entry point to AEO tracking: Lite $29/mo (15 prompts), Standard $189/mo (100), Premium $489/mo (400), with annual billing at roughly $25/$160/$422 effective.
- Base coverage is ChatGPT, Google AI Overviews, Perplexity, and Copilot; Google Gemini and Google AI Mode are paid add-ons at $9 to $149/mo each, so price full coverage honestly before comparing.
- The per-prompt math favors higher tiers: Lite costs ~$1.93 per prompt, Premium ~$1.22, and there is no tier between $29 and $189.
- Best fit: small teams running first tracking and proving the concept. Poor fit: agencies and multi-brand teams (go to Peec AI) and enterprises (go to Profound).
- Like every tracker, it measures your AI visibility; it does not improve it. The improvement work is content, structured data, and third-party citations.
The tool tells you the score; the work changes it
Whether you pick Otterly.ai or anything else in our best AEO tools guide, the tracker will keep telling you the same thing our data already shows: most of the citations behind AI answers are third-party pages, not yours. Acting on that is the actual job. An AI visibility audit from AEO Labs gives you the baseline and the plan, and our digital PR and citations work earns the third-party presence the engines actually cite. Start the tracking wherever your budget allows; just make sure someone is doing the work the tracker measures.
