- Base plans cover four engines (ChatGPT, Google AI Overviews, Perplexity and Copilot). Google AI Mode, Gemini and Claude are paid add-ons.

- Slynnk includes six AI tools in every plan from $69 a month, with a likely range on every number.
Otterly.AI is the tool people often try first when they want to start tracking AI search without a big commitment. At $29 a month for the entry plan, it lowers the cost of finding out whether ChatGPT and Perplexity mention your brand.
This Otterly.AI review covers what each plan includes, how the add-ons change the real price, who it suits, and the alternatives worth a look.
What is Otterly.AI?
Otterly.AI monitors how your brand, products and domains appear in AI search results. You enter the search prompts you care about and Otterly runs them across the engines in your plan, then reports brand mentions, citations and links, and suggests recommendations for improving your visibility.
The product is organised around workspaces and prompts. Lite gives you one workspace, while Standard and Premium add unlimited workspaces, which suits an agency that wants a workspace per client.
What Otterly.AI does well
A very low entry price
The $29 Lite plan is the cheapest published way to start with a mainstream AI visibility tool. For a founder or a small brand with one core topic, it answers the first question, whether AI mentions you at all, for the cost of a lunch.
Good reviews and responsive support
On G2, Otterly.AI is rated 4.8 out of 5 from 48 reviews at the time of writing, with users praising the interface, the pace of new features and the support team.
Integrations and developer access
Standard and Premium include a Data Studio connector, API requests and MCP requests, plus audit allowances (5,000 and 10,000 GEO URL audits a month). If you want AI visibility data in your own dashboards or workflows, those are included at a mid-tier price.
Agent analytics and audits
Otterly includes agent analytics events and GEO URL audits in its plans, which gives you some view of how AI agents reach your site and how ready individual pages are.
How much does Otterly.AI cost?
Otterly publishes monthly prices, with about 15% off for annual billing. The page shows two sets of numbers; the higher set is the monthly rate and the lower the annual one.
| Plan | Price a month | What is included |
|---|---|---|
| Lite | $29 | 15 prompts, 1 workspace, 4 engines, 3 recommendations a week |
| Standard | $189 | 100 prompts, unlimited workspaces, Data Studio connector, API and MCP |
| Premium | $489 | 400 prompts, unlimited workspaces, higher audit and API limits, personal onboarding |
| Enterprise | Custom | From 1,000 prompts, SSO, a customer success manager |
- Four engines are included: ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot.
- Google AI Mode and Gemini are add-ons: $9 each a month on Lite, $59 on Standard and $149 on Premium. Claude is $29, $109 or $439.
- Adding AI Mode and Gemini to reach the same six tools Slynnk covers takes the plans to about $47, $307 and $787 a month.
- Extra prompts cost $99 a month per 100 on plans above Lite.
What to check before you choose Otterly.AI
The price once you add the engines you need
The headline price covers four engines. If your customers also use Google AI Mode, Gemini or Claude, the add-ons can nearly double the bill, so price the version you will actually use.
How many prompts you will need
Fifteen prompts is a starting point, not a programme. Most brands outgrow Lite quickly, and the next step is $189. Count the questions your buyers ask before picking a tier.
How prompts turn into trustworthy numbers
Whichever tool you use, ask how many times each prompt is run and whether the figure shows its uncertainty, because AI answers vary from one run to the next. A reviewer on G2 also noted that sentiment analysis can be hyper-sensitive.
Who is Otterly.AI best for?
Choose Otterly.AI if
- You are a small brand, a founder or a freelancer who wants to start tracking for the lowest price.
- You want the API, MCP and a Data Studio connector at a mid-range price.
- You are comfortable adding engines as you need them and managing a prompt budget.
Choose Slynnk if
- You want ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Copilot included from the first plan, without working out add-ons.
- You need to defend a number in front of a client: its sample size, its likely range and whether a change is real.
- You want ranked fixes and drafted outreach next to the numbers.
- You are an agency that wants white-label reports and client links without a partner programme.
Where Slynnk is built differently from Otterly.AI
Otterly wins on entry price and Slynnk wins on completeness. A Slynnk Starter plan is $69 a month and includes all six AI tools, daily checks and 3,600 credits, which is about 20 prompts on every tool.
The other difference is what the numbers say. Slynnk stores every answer, matches mentions with a plain text search you can re-derive, and shows the sample size and likely range on each figure. When a number moves, it tells you if the move is bigger than the normal variation in AI answers, so you do not report noise as progress.
Where Otterly is ahead today: the API, MCP and Data Studio connector. Those are on Slynnk's list after launch.
