What CLEO by RegenAI is, and who it is for
One engine for the whole presence. RegenAI describes CLEO as running a brand's presence from the map to the model, autonomously and under your approval: Google Maps, search, AI search, social and reviews, with fixes written server-side into the website.[2]
Sold per site, on six-month terms. Plans are priced per site, profile or brand, each with a six-month minimum. The optional Orbit layer decides what to make, researches it and writes it in your brand voice.[1]
Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.

Where each shines
Both tools are built well for different teams. Each point is a strength, read from that vendor's own pages.
Where CLEO by RegenAI shines
- It does the work. CLEO writes fixes into your CMS, publishes articles, builds backlinks and, on the social plans, posts and replies, all of which a measurement tool leaves to you.[1]
- Breadth beyond AI answers. Google Business Profile, reviews and social sit in the same vendor and, on the bundles, the same plan.[1][2]
- Bing AI and DeepSeek on the GEO plan. Both are among the seven engines available on SEO + GEO, with up to four running at a time.[1]
Where Proofsource shines
- More evidence per question. CLEO's SEO + GEO plan monitors 15 prompts six days a week. A Proofsource Custom plan is sized to the questions you need and re-reads them every day.[1]
- No minimum term to find out. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. Every CLEO plan carries a six-month minimum.[1]
- Uncertainty stated, not hidden. Every Proofsource number carries a 95% Wilson interval, so you can tell a real change from the normal day-to-day movement in AI answers before crediting anyone with it.
- All four panel engines at once. Proofsource runs ChatGPT, Perplexity, Claude and Google AI Overviews together on every plan and all 10 on Custom. CLEO runs up to 4 of its engines at a time.[1]
