Use Case Recommendations
Best for: AEO Mantis
AEO Mantis is an AI-visibility monitoring platform that tracks whether assistants name your brand when a buyer asks them who to buy from. It takes scheduled snapshots across eight answer surfaces — ChatGPT, Perplexity, Google AI Overview, Google AI Mode, Gemini, Claude, Bing Copilot and Grok, with Microsoft Copilot listed as launching soon — and reports mention rate and sentiment per platform, share of voice against named competitors, and drift over time so you can tell whether a change actually moved anything. A Sources view ranks the domains those platforms cite when they mention you, which is the practically useful output: it tells you which third-party pages to go influence rather than leaving you optimising your own site blindly. A site audit checks whether AI assistants can read your pages at all, and an opportunities feed turns gaps into scheduled reports for the team. Beyond monitoring it generates source-backed content aimed at GEO and SEO together, with a per-plan monthly article allowance. The plan structure is unusually granular for the category — brands, seats, unique prompts tracked, monitoring frequency, competitors tracked and platform coverage all scale independently, so the cheap tiers cover ChatGPT and Perplexity while full eight-platform coverage sits at the agency tier. It positions itself as an operating layer for marketing, SEO, content, product and growth teams that treat AI visibility as a growth metric.
Ideal use cases:
- •Teams or individuals who need scheduled monitoring across chatgpt, perplexity, google ai overview and mode, gemini, claude, copilot and grok
- •Teams or individuals who need mention rate and sentiment reported per platform
- •Teams or individuals who need ranked list of the domains ai cites when mentioning you
- •Teams or individuals who need share of voice against named competitors
- •Anyone focused on geo workflows
- •Anyone focused on aeo workflows
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
