Vercatus vs OtterlyAI: Prompt Tracking or a Verdict on Every Change

OtterlyAI and Vercatus both measure how AI answers mention brands. OtterlyAI is built to track a panel of prompts at a low price and to help you write content for them. Vercatus is built to explain why an engine picks a competitor, hand you the exact change, and read a verdict on whether it worked. If you are looking for an OtterlyAI alternative, the useful question is which of those two jobs you need done.

In short

• OtterlyAI sells prompts and monthly credits: 16, 120 or 403 prompts on Lite, Standard and Premium, at €29, €189 and €489 a month excluding tax. Every check of a prompt on an engine costs a credit.
• Vercatus sells topics and fixed engine sets: four engines on Essentials, all ten from Growth, with tax included in every price.
• The two price lists are not like for like. Run the same evaluation on both, on your own topic.

	Vercatus	OtterlyAI
Engines by plan	Essentials: ChatGPT, Google AI Overviews, Google AI Mode, Perplexity. Growth and up: all ten, adding Claude, Grok, Le Chat and You.com	Seven listed: ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Google AI Mode, Gemini and Claude. The Lite, Standard and Premium cards say “4 of 7 AI engines”; a line under them says every plan can track every engine, with each engine using credits
Unit of a plan	Topics, sites and polled answers a month; each allowance is in the plan reference	Prompts (16, 120 and 403; Enterprise from 1,000) and monthly credits (2,000, 15,000 and 50,000). One credit is one prompt checked once on one engine, so a prompt tracked daily on one engine uses 31 credits a month; a Claude answer counts as 3
Published price	Essentials $59, Growth $299 and Agency $990 a month, tax included; Enterprise from $4,900 a month on an annual contract; see the pricing page	€29, €189 and €489 a month excluding tax; Enterprise custom. Monthly or annual, with 15% off annual. Credit packs: 5,000 for €65 on Standard, 10,000 for €99 on Premium
How answers are collected	ChatGPT’s app and Google’s and Bing’s results pages as people see them; the other engines through their own web search; many phrasings per topic, with a range on every share	Its FAQ says it sends user-style search prompts to the AI engines and analyses the responses for mentions, citations and source links, filtered by country, and that manual searches can differ because platforms use memory and personalisation

Where the two differ

Area	As OtterlyAI describes it	Where Vercatus sits
Unit	Prompts you choose, each checked once per engine per run, paid for in credits	Topics: a cluster of questions sampled in many phrasings, with the AI demand behind it as a range
Shares	Brand visibility and sentiment, citation sources, competitor benchmarking and a share of AI voice	Answer Share with its range for you and every brand named, engine by engine, with named and cited apart
What to change	Recommendations (3 a week on Lite, unlimited from Standard), a content audit, a predictive score before you publish and content briefs	Recommendations ranked by expected gain, with steps, a draft on request and an acceptance check a machine runs; hand-offs to coding agents and trackers from Growth
Proof of change	Its pages describe a score before publishing; they do not describe reading the result against pages left alone, so ask how it tells a change from drift	A verdict on every shipped recommendation, read on days 14, 30 and 45 against topics left alone, graded A to D
Site checks	Crawlability checks in its content audit, and Agent Analytics for how AI agents crawl your site	SEO Health (rules checked by code), a site audit as nine machine identities, and crawler traffic from Cloudflare, log drains or uploads
API and MCP	API and MCP requests from Standard (2,000 a month each), more on Premium; none on Lite	Read-only keys and the MCP server on every plan; write keys from Growth
Brands, seats and markets	Unlimited brands, competitors, team members, countries and languages on every plan	Sites, topics and seats set by plan, with viewers free; markets set per site
Before you pay	A 7-day free trial, no card needed	A free audit once, with real answers from four engines; a full refund if you ask within 14 days of your first payment

“As OtterlyAI describes it” means only what its pages say; ask the vendor about anything not listed. Where OtterlyAI’s unlimited brands, seats and countries fit how you work, that is a real advantage on cost.

Questions to ask any vendor, including us

• Population. Which answers does a share count, on which engines and in which market? Two visibility figures are not comparable until those match.
• Range. Does the figure come with its range, and how many answers is it read from?
• Proof. After you ship a change, does anything compare it with what you left alone?
• Credits. If a plan is priced in credits, what does a month of your real panel cost across the engines you need, and what happens at the limit?

Who each is likely to suit

Your situation	Likely better fit
A small team that wants a first count of mentions on a fixed prompt panel, cheaply	Evaluate OtterlyAI’s Lite plan
Many brands, markets or colleagues on one price	Evaluate OtterlyAI’s unlimited brands, countries and team members
A team that wants to know why a competitor is picked, get the exact change and see whether it worked	Evaluate Vercatus
You need both a cheap panel and proof of change	Possibly both; check whether the overlap is worth the cost

Questions people ask

Is OtterlyAI cheaper than Vercatus?

Its entry plan has the lower published price, and the two are not like for like. OtterlyAI’s Lite is €29 a month excluding tax for 16 prompts and 2,000 credits. Vercatus’s Essentials is tax included and measures a small set of topics, each a cluster of questions, on four engines; the plan reference lists the allowance. Price the panel you would really run before you compare.

Do they cover the same engines?

Partly. OtterlyAI lists seven, including Gemini and Claude. Vercatus reads ten from Growth, adding Grok, Le Chat and You.com, and four on Essentials. OtterlyAI’s plan cards say “4 of 7” while a line below says every plan can track every engine at a credit cost, so ask which applies to the plan you are quoted.

Is this page neutral?

No. It is published by Vercatus. It tries to be fair by quoting OtterlyAI’s own pages, dating every figure and saying what it did not test.

Vercatus’s pricing page states its plans, and how it works walks through the loop. For a broader shortlist, see the best AI visibility tools, Vercatus alternatives and Vercatus vs Ranketta.
