OtterlyAI, an AI search monitoring and optimization platform, has accepted TOS as an Agency Partner. Since early October 2026, TOS has been listed in OtterlyAI’s partner directory. For clients who use TOS for GEO and AEO, this adds a daily source of data on how often their brand is mentioned and cited in AI answers.
This article explains what the platform measures, what the Agency Partner program includes, and how TOS uses the data in GEO (generative engine optimization) and AEO (answer engine optimization) projects. It also covers what international companies should know when measuring their brand’s AI visibility in Vietnam.
What is OtterlyAI?
OtterlyAI is an AI search monitoring and optimization platform built by an Austrian company. The product launched in October 2024, and OtterlyAI’s About page says 40,000 marketing professionals were using it as of August 2026.
The product covers three areas: prompt research, monitoring and optimization. Users define a set of prompts, the sample questions their customers might ask an AI assistant. The platform runs these prompts every day and records which brands are mentioned and which sources are cited.
It supports up to seven AI platforms: ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity, Microsoft Copilot and Claude. The Lite, Standard and Premium plans include four of them; the other three are paid add-ons.
The main metrics are brand mentions, domain citations, share of voice against competitors, average brand position and sentiment. Domain citations count how often a domain is cited as a source in AI answers (see the TOS guide on how to get cited by AI).

The OtterlyAI Agency Partner program and the TOS listing
The Agency Partner program is for marketing and SEO agencies that use OtterlyAI to serve their clients. To join, an agency needs an active Standard, Premium or Enterprise plan. There is no extra fee for the program itself.
TOS appears in the OtterlyAI Agency Directory, which lists more than 150 agencies (as counted by TOS on 2 October 2026). The TOS profile carries a Vietnam country tag and service tags including GEO, AEO, AI Visibility Strategy and SEO.
The program pages list these benefits:
- More tracked prompts: 150 instead of 100 on Standard, 500 instead of 400 on Premium.
- Unlimited workspaces, with each client’s data kept separate.
- Agency-branded reports, built with Google Looker Studio.
- Previews of new research and features, plus onboarding support for new partners.
- Co-marketing and co-selling opportunities.

How TOS uses AI search tracking data in client work
Monitoring and regular reporting already form one step of the TOS GEO and AEO process, and TOS has added OtterlyAI to the tools it uses for that step. The data serves four purposes:
- Before-and-after measurement: a baseline is recorded on a fixed prompt set before work begins, and the same set is then tracked in each reporting period to show the trend.
- Competitor tracking: mentions and share of voice show where a brand stands against its competitors on each AI platform.
- Source tracking: citation data shows which domains AI answers draw on. Combined with a page-level GEO audit, this gives TOS a basis for deciding which content to add or expand.
- Regular reporting: TOS builds client reports from the tracking data, because OtterlyAI does not currently offer a native white-label version of its platform.
The tracking scope (number of prompts, AI platforms and countries) depends on the plan and the project. The data shows where a brand stands and how that is changing. It is not a substitute for content optimization, and it does not improve visibility on its own.
The TOS AI Visibility Checker and OtterlyAI measure different things. The checker scores the signals on a website, while OtterlyAI tracks how AI platforms answer a defined set of prompts every day. The two complement each other.
Measuring AI search visibility in Vietnam with OtterlyAI: the TOS perspective
According to the OtterlyAI help center, Vietnam is one of more than 70 supported countries and is covered on all seven AI platforms. Each prompt is assigned a country, and answers are collected as if a user were searching from inside that country.
Monitoring works with prompts in any language, so a company entering Vietnam can track the same questions in English and in Vietnamese. Vietnamese is also available in the AI Prompt Research tool. The dashboard itself is in English, and OtterlyAI does not currently offer other interface languages.
Keep three limits in mind when reading the numbers. One is scope: the tool tracks the prompts that have been defined, not every question real users ask. Another is personalization: OtterlyAI sends prompts as a neutral, non-personalized user, so results can differ from what any individual user sees.
The third is brand detection, which relies mainly on matching the brand names that have been entered. Brands should list every name variant they use: the international name, Vietnamese spellings with and without diacritics, and abbreviations. Because of these limits, TOS recommends reading the data as trends rather than single-day figures, together with the details of the prompt set used for measurement.
Frequently asked questions about OtterlyAI
Which AI platforms does OtterlyAI track?
Up to seven. The Lite, Standard and Premium plans include ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Claude, Google AI Mode and Gemini are paid add-ons, so coverage depends on the plan and add-ons in use.
Does OtterlyAI support Vietnam and the Vietnamese language?
Yes. Vietnam is on the list of supported countries, and prompts can be entered in Vietnamese as well as English. The dashboard is in English, and OtterlyAI does not currently offer it in other languages.
Why can tracking results differ from the answers you get in ChatGPT?
OtterlyAI sends prompts as a neutral user, while the answer each person sees depends on their session, location and account settings. Data is collected through the AI platforms’ public web interfaces, except for Claude, which is tracked through its API.
How much does OtterlyAI cost?
As of early October 2026, OtterlyAI’s list prices on monthly billing are $29 per month for Lite (15 prompts), $189 for Standard (100 prompts) and $489 for Premium (400 prompts). Enterprise is priced on request. These are software prices in US dollars, not TOS service fees.
