Use Case Recommendations
Best for: HarperFlow
HarperFlow runs a Webflow blog end to end for AI-search visibility: it discovers opportunities, researches and writes the article, styles it to match the site, and publishes into the Webflow CMS on a schedule, with eight to twelve cited sources in each piece. The Webflow-exclusive scope is the deliberate trade — rather than building shallow integrations with every CMS, it commits to one and handles styling and delivery properly. What makes the company unusual for this category is that it publishes its own primary research and lets you recompute it: a study of 117 AI answers across three engines, an agency index covering 1,464 measured agencies, and a downloadable dataset behind every figure. Two of its findings are the sort a vendor would normally bury — that Reddit's share of cited sources collapsed from 87% to 18% within fifteen days, and that Reddit appeared in 87% of answers while being the top source for none of them — which cuts against the prevailing Reddit-first advice much of this category sells. There is a free GEO audit that checks a site's AI-search visibility without an account, and a comparison hub that names competitors directly. Pricing is a single flexible plan set by monthly article volume rather than a feature ladder, with per-article cost published at every volume.
Ideal use cases:
- •Teams or individuals who need end-to-end webflow pipeline: discover, research, write, style, publish
- •Teams or individuals who need 8-12 cited sources in every published article
- •Teams or individuals who need free geo audit of ai-search visibility with no account
- •Teams or individuals who need volume-based pricing with per-article cost published at every tier
- •Anyone focused on geo workflows
- •Anyone focused on aeo workflows
Best for: Limy
Limy tracks and monetises brand visibility inside AI search. Its framing is that LLMs create a new revenue model it calls Business to Agent: agents now evaluate, choose and act on behalf of humans, so being described accurately by a model matters the way ranking did in classic search — and the company's specific position is that visibility alone is not the metric, convertible and measurable visibility is. The platform is organised around five surfaces: visibility, revenue, performance, narrative and perception, giving brands an operational layer to influence how they are represented in AI-mediated buying rather than only a dashboard that reports on it. Plans are metered on unique prompts monitored, the number of AI models tracked, and how many languages, regions and domains are covered, with a content-generation allowance included at every tier so a detected gap can be acted on inside the same tool. This is the same AI-search-optimisation category AISOTools itself covers, approached from the revenue-attribution end rather than the citation-counting end, which makes it a useful comparison point for anyone evaluating GEO and AEO monitoring tools. Every plan starts with a 14-day trial and no charge until day 15. Limy is a twelve-person team and one of only a handful of tools in this space that publishes its full rate card rather than routing every enquiry through a demo, which makes it a useful price anchor for the whole AI-visibility category.
Ideal use cases:
- •Teams or individuals who need monitors brand mentions across multiple llms and ai search surfaces
- •Teams or individuals who need ties ai-search visibility to revenue rather than mention counts
- •Teams or individuals who need visibility, revenue, performance, narrative and perception views
- •Teams or individuals who need multi-language, multi-region and multi-domain monitoring
- •Anyone focused on aiso workflows
- •Anyone focused on geo workflows
