Key takeaways
- Otterly.AI is the quickest to get running for a small team. Rankscale is close behind and cheapest at the entry level. Profound asks the most up front, and most brands now reach it through a trial or an enterprise contract.
- Nobody has published an independent, hands-on measurement of minutes-to-first-data for these three tools. The "quick setup" claims you will read are vendor marketing or reviewer impressions.
- Data quality depends on engine coverage, run frequency and whether you can export the raw responses. Profound's full engine list and exports sit on its enterprise tier, Otterly gates Gemini and Claude behind add-ons, and Rankscale's credits make daily tracking on Claude expensive.
- All three are monitors. If you also want to fix what you find, you will need something to act on the data.
What "pure tracker" means here
A pure AI visibility tracker runs a set of prompts against ChatGPT, Perplexity, Google AI Overviews and similar engines, records the answers, and shows you whether your brand was mentioned, where, and which sources were cited. That is the whole job. No content generation, no crawler logs, no traffic attribution.
That narrowness is fine if you just need a scoreboard. It also means the two things that matter most are how fast you get the scoreboard running and whether you can believe it. So that is what this guide compares.
A caveat before the details. I could not find any independent test that timed setup or benchmarked tracker output against what a real user sees in the ChatGPT or AI Overviews interface. Almost everything below on pricing and mechanics comes from the vendors themselves or from their competitors' reviews. I flag the source where it matters.
The three tools at a glance
Profound
Otterly.AI
| Profound | Otterly.AI | Rankscale | |
|---|---|---|---|
| Entry price | 7-day trial for brands; Agency Growth $99/mo plus $399/mo per client workspace; enterprise custom | Lite $29/mo (15 prompts) | Essentials $17/mo billed yearly ($20 list) |
| Mid tier | Older Growth plan listed at $399/mo, annual only (may be retired) | Standard $189/mo (100 prompts) | Pro $99/mo (1,200 credits) |
| Engines | Up to 9 on enterprise | 4 on Lite, Gemini and Claude as paid add-ons | 17+ engines listed on all plans |
| Pricing model | Seats, prompts, workspaces | Prompts | Credits per answer, varies by engine |
| Exports and API | Enterprise (CSV/JSON, API, MCP) | Not detailed in sources | REST API from Pro+ |
| Best fit | Large brands with a program budget | Marketing-led teams and agencies | Budget-conscious teams and small agencies |
Prices come from vendor pages and third-party reviews (Otterly's comparison page, honeyb.ai's Rankscale review, Geoptie's Profound review). Confirm on each vendor's live pricing page before buying. Two of those reviewers are competitors, and Rankscale's own pricing page showed different credit figures than the honeyb.ai table.
Setup time compared
Otterly.AI
Rank Math's review calls Otterly's interface simple and says you can start monitoring prompts without technical knowledge. Self-serve signup and a flat prompt allowance mean the main work is deciding which 15 to 100 prompts to track. If you already know your category and competitors, a first run is plausibly a same-day job. That is my read, not a measured number.
Rankscale
Otterly's own roundup describes Rankscale as "quick to set up – minimal configuration." Take it with salt, since Otterly is a competitor, but it matches the product shape: cheap plan, self-serve, prompt-level monitoring. The extra setup step is credit planning. You have to work out how many credits your prompt list will burn before you pick a plan, which I cover below.
Profound
Profound has the heaviest start. For brands there is no standard self-serve paid plan on the current pricing page, just a 7-day trial (50 prompts run daily on ChatGPT, Gemini and AI Overviews, limited credits) or a custom enterprise conversation. According to Geoptie, the trial uses a recommended prompt set you cannot customise, keeps no history and has no exports or API.
A G2 reviewer quoted by Discovered Labs says you need to "spend time setting up keyword lists for prompt tracking during initial setup." The same review mentions reported problems with the Watched URL tab, including slow load times of up to 15 seconds. That is one reviewer's experience, but it fits a tool built around larger programs.
One warning on staleness: older write-ups list Starter ($99/mo) and Growth ($399/mo) tiers, both annual only. The current official page seems to have dropped them for brands. Check before you plan around them.
Setup summary
| Step | Profound | Otterly.AI | Rankscale |
|---|---|---|---|
| Self-serve signup for brands | Trial only | Yes | Yes |
| Sales call likely | Yes, for ongoing tracking | Only at enterprise | Only at enterprise |
| Custom prompts from day one | Not on the trial, per Geoptie | Yes | Yes |
| Extra planning required | Prompt lists, contract scope | Choose engines and add-ons | Credit budget |
| Free trial | 7 days | See current pricing page | 7 days on Pro |
Data quality compared
Data quality is harder to pin down than setup, because no one has published a head-to-head accuracy test. What you can compare is the inputs that shape the data.
Engine coverage
Profound's enterprise tier covers up to nine engines: ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, Copilot, DeepSeek, Exa and Claude. Lower tiers are narrower, and older plan descriptions had Starter on ChatGPT only. Otterly's Lite plan covers ChatGPT, AI Overviews, Perplexity and Copilot, with Gemini and Claude as paid extras (Gemini bumps Standard from $189 to $248, and Claude is $29, $109 or $439 depending on plan). Rankscale lists 17+ engines on every plan, but you pay for each answer in credits.
Credit math on Rankscale
This is where Rankscale surprises people. Per honeyb.ai, an answer costs 0.25 credits on ChatGPT, Gemini, Perplexity and AI Mode, 1 credit on DeepSeek and 2 credits on Claude. Claude is 8 times the cost of ChatGPT. Monthly cost is roughly prompts, times the credit cost of your engines, times how often you run.
Rankscale's own calculator example is 50 prompts at 0.75 credits per run, weekly, for about 162.5 credits a month. Run those same 50 prompts daily on four engines plus Claude and honeyb.ai puts you near 4,500 credits, which means the $385 Growth plan. Honeyb.ai is a competitor, so its framing is biased, but the arithmetic is checkable against the published rates.
The practical upshot: Rankscale is cheap if you run weekly on the common engines, and not cheap if you want daily data on everything.
Frequency and statistical noise
AI answers vary from run to run. A tracker that samples a prompt once a week is giving you one draw from a noisy distribution. Daily runs smooth that out. Otterly's Lite plan tracks daily. Profound's trial runs 50 prompts daily. Rankscale's cadence runs from hourly to monthly, but each step up costs credits.
Engines also behave differently. Promptwatch's average sources per response data shows ChatGPT citing about 5 sources per web-search answer, Google AI Overviews about 10, and Perplexity almost exactly 10 every day. Copilot's average swung from under 2 to nearly 17 within weeks before settling low. Two things follow. Compare engines only after normalising, and judge Copilot on monthly trends rather than weekly snapshots.
History and exports
If you want to build your own reporting, exports matter. Per Geoptie, Profound's trial has no history, exports or API, while enterprise adds all-time history, CSV and JSON exports, API and MCP access, and SSO. On Rankscale, Essentials has no REST API or team workspaces, and Pro+ is where API access starts. Otterly's sources do not spell out its export options, so check before you commit.
What the independent rankings say
Conductor's evaluation guide (updated September 10, 2026) ranks Profound second and Rankscale fifth, with Conductor itself first. Conductor sells a competing product, so treat the order as one vendor's view. Otterly's own 25-tool roundup lists Profound at 10+ engines from $99 a month and itself at 6 engines from $29. Self-reported again. None of this is a measurement of accuracy.
How to test data quality yourself
Since nobody has done it for you, run a short bake-off. It takes an afternoon.
- Pick 20 prompts you care about, mixing branded, category and competitor comparison queries.
- Run them in the actual ChatGPT and Google AI Overviews interfaces and save the answers with dates.
- Load the same prompts into each tool's trial or lowest plan.
- Compare mention presence, brand order and cited domains against your saved answers.
- Repeat on a second day to see how much the tool and the engine vary on their own.
The point is not to find a perfect match. It is to see which tool's output is stable enough to trust for trend lines.
Which one should you pick
| If you are... | Lean toward | Why |
|---|---|---|
| A small team that wants a dashboard this week | Otterly.AI | Simple setup, flat prompt-based pricing, daily tracking |
| Price-sensitive and fine with weekly runs | Rankscale | Lowest entry price, broad engine list, budget the credits first |
| A large brand with budget and compliance needs | Profound | Widest engine list, exports, API, SSO on enterprise |
| An agency with many clients | Profound Agency Growth or Rankscale Growth | Both have agency pricing; compare per-client costs |
My honest take: for most teams under 100 prompts, Otterly or Rankscale will be live faster and cost far less than Profound. Profound earns its price when you need nine engines, history and exports in one place. Be careful with Rankscale's Claude coverage if you plan to run daily.
What pure trackers do not do
All three stop at reporting. They tell you that a competitor is cited and you are not. They do not tell you whether AI crawlers can actually read your pages, they do not attribute AI-referred traffic, and they do not write or publish the content that closes the gap.
If you want that loop closed, Promptwatch is the end-to-end option. It monitors real AI interfaces, shows AI crawler logs, traces citations and traffic, and then has Content Agents write and publish pages for the gaps. It has a head-to-head page against Profound and one for Otterly if you want the detailed comparison. The 7-day free trial and the free AI visibility report are the low-effort ways to test it; confirm plans at promptwatch.com/pricing.
For a wider shortlist, the GEO software directory at bestgeosoftware.com lists more trackers, and ai-rank-tools.com focuses on AI rank trackers.
Bottom line
Pick Otterly.AI or Rankscale if you want to be tracking by the end of the day and your budget is a few hundred dollars a month at most. Pick Profound if you need the engine breadth, history and exports and can handle a sales-led process. Whichever you choose, run the 20-prompt bake-off first, because the only independent data on setup time and accuracy is the data you collect yourself.
