Otterly.AI alternative: when sirefs fits better, and when to stay

We make sirefs. To keep this fair, every fact about Otterly.AI comes from Otterly's own pages, checked on 22 October 2026 and listed under Sources. Otterly's pricing page showed euros to a visitor in Denmark and dollars elsewhere, with the same numbers; we write them without a currency where that matters. Where Otterly is the better choice, we say so.

Which should you choose?

• Otterly.AI if you want daily data at the lowest entry price, a free trial before you pay, Looker Studio reports, or its agency partner programme.
• sirefs if you want all eight engines on every plan without add-ons, more prompts for the money at entry, and the collection method, sample size and confidence interval on every number.

What is Otterly.AI?

Otterly.AI is an AI search monitoring tool from OtterlyAI GmbH in Austria, with a GEO audit built in.^{1, 7} It says more than 40,000 marketing professionals used it as of August 2026.⁸

Add-ons. Google AI Mode and Gemini cost from 9 a month each on Lite, and Claude from 29; the add-ons cost more on Standard and Premium. Grok isn't offered. Standard and Premium can add 100 prompts for 99 a month. Annual billing takes 15% off.¹

Beyond tracking. Every plan includes GEO audits (1,000 a month on Lite) and unlimited countries and languages. Brand Profiling arrived on 21 October 2026.^{1, 5} The API and an MCP server, which arrived in May and June 2026, are on Standard and Premium, with a Looker Studio connector.^{1, 4}

Agencies. The Agency Partner status on Standard or Premium raises the prompts to 150 or 500 and adds pitch workspaces and branded Looker Studio reports.¹

How it collects answers. Through the platforms' public web interfaces, such as chatgpt.com, and through the API for Claude only. Prompts can be assigned to a country.²

How do you test sirefs against Otterly?

1. Take 15 to 25 prompts from your Otterly project, the ones closest to revenue.
2. Add them to sirefs in the same countries, and compare the engines both collect.
3. Wait for enough answers. Weekly data needs several rounds before the intervals narrow; daily data on Pro gets there sooner.
4. Read the sources each tool shows: the pages the engines cite are your to-do list either way.

For a first look, the free check audits your site and lists the questions sirefs would track for it, and the live demo shows the dashboard on a real project. See pricing for the plans.
