Where OtterlyAI is strong
OtterlyAI is easy to start with. Its pricing page shows plans priced by the number of search prompts, with unlimited team members and daily tracking. At the time of writing (September 2026), the entry Lite plan is listed at $29 a month for 15 prompts. There is a free trial for new users, and annual billing comes with a discount.
It covers a wide set of engines. The help centre lists ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Gemini, Claude and Microsoft Copilot. It says it queries these daily as a neutral, non-personalised user, so results are not skewed by browsing history.
Citation tracking is a core feature. The features page says every domain and URL cited in AI answers is checked daily. That makes it simple to see which pages AI engines lean on in your topic.
A few other features are worth a mention.
- Brand sentiment. Shows whether a brand is recommended warmly, mentioned with caveats or dismissed.
- AI Prompt Research. Helps find prompts people in your industry might use on ChatGPT.
- GEO Audit. Crawlability checks, a content audit with prediction, and content briefs.
- Workspaces. Several brands and clients inside one subscription.
- Looker Studio connector. Pulls OtterlyAI data into your own dashboards, with scheduled email delivery.
According to its website, OtterlyAI is used by more than 40,000 marketing professionals.
Where Axiom GEO is different
The main difference is answer accuracy. Being mentioned only helps if the answer is right. Axiom GEO builds a fact sheet of your business, approved by a person, then checks every claim in an answer. Each claim is marked correct, partly true, wrong, out of date or not covered. Similar problems are grouped into issues with the engines that said it and a suggested fix. You can read more on the answer accuracy page. OtterlyAI's site does not list a check like this.
The second difference is classic search in the same login. Axiom GEO includes rank tracking to town level anywhere in the UK, Google AI Overview tracking, Google Business Profile reviews, local citations and link building. OtterlyAI's site does not list rank tracking or review tools.
The third is client reporting. OtterlyAI's white label help page says its interface, branding and URLs cannot be customised, and points agencies to its Looker Studio connector. Axiom GEO sends client reports as white label monthly PDFs with the client's logo. Numbers are re-checked by automated claim checks before a report goes out. Each client workspace is isolated at database level, with its own client logins.
Share of voice is scored a little differently too. Axiom GEO weights each mention by position, so being named first counts more than being named last. A 0-100 prominence score folds in recommendation, citations and sentiment. AI citation tracking classifies each cited domain, such as directory, review site, listicle or competitor page.
Local and regional work is built in. You can run the same prompts per country or region, with location-aware prompts for AI engines, and split share of voice by geography. That helps a firm with several branches see where it shows up and where a rival is named instead. Reddit communities discovery also finds the subreddits that AI engines cite in your topic, using answers you already hold.
How answers are collected also differs, and it is fair to say so. Axiom GEO asks each engine through its API. Gemini and Claude answer from what the model already knows, which shows how the model itself sees your brand. Consumer apps can differ a little because of personal history, location and model version.
Price is the other honest difference. Axiom GEO starts at £500 a month on the pricing page, which is well above OtterlyAI's entry plan. The Starter plan covers Gemini only. The extra cost pays for accuracy checks, classic search, reporting and work management in one place, so it makes most sense when you need those.
Which should you choose?
