GEO tools measure your AI visibility.A GEO agent does the work.

More and more buying decisions start with a question to ChatGPT, Claude, Perplexity or Gemini. A founder asks which tool to buy, the engine writes one answer, and the brands that answer names make the shortlist.

The work of getting named is AI search optimization, also called GEO (generative engine optimization) or AEO (answer engine optimization). It has drawn serious money. HubSpot agreed to buy XFunnel in October 2025 (HubSpot). Adobe agreed in November 2025 to buy Semrush for about $1.9 billion (Semrush). Sitecore bought Scrunch in June 2026 (Sitecore). Profound raised a $96 million Series C in February 2026 and a $180 million Series D in September (Profound).

Most of that money first bought measurement: tools that show where you stand in AI answers and hand you a list of what to improve. In 2026 the same tools began adding agents of their own, and the gap with an AI search agent narrowed. It did not close. A tool's agent is a feature your marketing team runs. An AI search agent is someone you hire to own the job. This post walks through what each does today, and which one fits whom.

#What AI search tools do well

An AI search tool is an analytics platform for AI answers. Peec AI, Profound and Otterly track how often ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews and AI Mode name your brand, how they describe it, which sources they cite, and how you compare with your competitors. You cannot improve a number you cannot see, and measuring AI search visibility goes deeper on which numbers matter.

Each is built for a clear buyer. Peec AI presents itself as an AI search platform for marketing teams and SEO agencies, from $95 a month (Peec AI pricing). Otterly starts at $29 a month, for solo marketers and small teams (Otterly pricing). Profound sells to enterprise teams and quotes its price after a free trial (Profound pricing).

For a team with writers, SEO and PR people, a dashboard is the right buy. It takes a capable team's judgment and makes it faster.

#The tools now do part of the work

The category is moving toward execution, and that deserves credit.

• Peec AI added agent actions, generated from your data with pre-built and custom skills, next to recommended actions ranked into earned and owned (Peec AI pricing).
• Profound now sells an AI marketer, in its own words: "Research, write, report, and collaborate with a superintelligent teammate who knows your brand" (Profound pricing). Its workflows publish to your CMS after a person approves (Profound).
• AirOps drafts content and publishes it after approval, and its Offsite product works on placements on third-party publisher sites, self-serve or as a managed service (AirOps Offsite).
• Otterly adds recommendations to its tracking, and content audits on its agency plans (Otterly pricing).

Two things hold across the group. The execution is built for marketing organizations: a workbench your team configures, staffs and operates. And the decisions stay with that team: which questions to track, which fix comes first, who writes it, who ships it.

#The work that moves the number lives off your site

When someone asks a model for a recommendation, it composes a reply from sources it trusts. Some are the brands' own pages. Many are independent articles, roundups, review sites and community threads, Reddit among them. Which sources win depends on the engine and on the question, and the data shows no universal top source (Search Engine Land).

So a large part of the highest-leverage AI search work lives off your domain. It is a mention in a roundup a journalist writes. It is a genuine reply on the thread where a buyer is deciding. It is a comparison page that answers the exact question an engine is asked. AirOps chases the publisher side for enterprises. The community side stays hands-on, because a person has to read the thread and write a reply worth reading.

For a founder, that is the wall. The list is right, and no one on the team is free to work through it.

#An AI search agent owns the job

An AI search agent is software you hire to do that work. Obi is one: an AI Search Employee for founders and GTM teams. It works from the agent harness you already use, through its command-line tool and its skill.

• It starts from your ideal customer profile and picks the buying questions those customers ask AI.
• On a paid pack, it reads the answers on ChatGPT, Gemini and Google AI Overviews every week, with Claude and Perplexity as options. The free plan reads ChatGPT and Gemini once a month.
• It decides what will move your visibility and proposes each strategy with its reason: a technical fix, a comparison page, an FAQ page, an article, a competitor analysis.
• It drafts the pages with you in your AI assistant, from your data and in your voice, for you to review and publish.
• Off your site, it proposes a reply for the Reddit thread where your buyer is asking, for you to post from your own account, and a pitch for the journalist worth contacting, for you to send.
• It checks that what you published can be reached by the engines, and flags what third-party pages say about you that is wrong or out of date.

You keep control of what goes live. Obi does the work around it.

#Effort, impact and outcome

Three questions show the difference between a tool and an agent.

• Effort. A tool asks you to read the dashboard, plan the work, staff it and ship it. An agent asks you to approve the work and publish it.
• Impact. A tool improves your decisions. An agent changes what gets published and where your brand appears.
• Outcome. A tool gives you a clearer picture. An agent gives you the pages and the strategies that can earn citations. Neither can promise when an engine will pick them up.

Here is how the five line up, as each vendor's site listed them in November 2026.

#Which one fits you

Each of these is a strong choice for the right team.

• A marketing team that wants the sharpest read on its AI visibility: Peec AI or Profound.
• An enterprise program that wants content and publisher placements at scale, with a managed option: AirOps.
• A small budget that needs tracking and recommendations: Otterly.
• A founder or a GTM team that needs the work done without hiring for it: an AI search agent such as Obi.

Some teams run a dashboard and an agent side by side.

#Where AI search goes next

The first wave of AI search tools gave marketers eyes on how AI talks about their brand. The tools are now adding hands to that view, for the teams that run them. For a small team, the next step is an employee that owns the job: it picks the questions, does the work, and hands you what to publish.
