What Zutrix is, and who it is for
SEO first, AI included. Zutrix's core is rank tracking, keyword research, backlink monitoring, site audits and a content editor. AI Search Visibility is one module, included on every plan.[1][2]
Eight AI models. The AI module monitors brand visibility across 8 models, naming Claude, GPT-5 and Gemini among them, with brand mention analysis and sentiment scoring.[1]
Built for SEO professionals and agencies. Plans scale by keywords tracked and team members, and the Agency and Enterprise plans add white-label reporting.[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 Zutrix shines
- SEO and AI in one login. If you also need rank tracking, backlinks and site audits, Zutrix covers them in the same plan as AI visibility.[1]
- Eight models on every plan. The AI module covers 8 models from the $19 Starter plan. Proofsource covers four on every plan and ten on Custom.[1]
- Low entry price. Starter is listed at $19 a month on weekly checks.[1]
Where Proofsource shines
- Built for the buyer question, not the keyword. Proofsource runs the questions your buyers ask AI and shows which ones name you and who gets named instead. Zutrix's AI module is one feature inside a keyword-led suite.
- Free to start, no card. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. Zutrix's trial is 7 days for $7.[1]
- A stated method. Proofsource publishes a 95% Wilson interval with every percentage. Zutrix's pricing page does not describe how AI visibility is measured.
Proofsource or Zutrix: the fair verdict
Pick Zutrix if you want classic SEO tooling first and AI visibility as part of the same subscription, at a low published price.
Pick Proofsource if AI answers are the channel you are trying to win, and you want each buyer question tracked with the cited pages and a draft fix for every gap.

Already using Zutrix?
You do not have to choose on day one. Here is how teams run Proofsource beside Zutrix and decide on their own data.
Keep Zutrix running
Nothing about trying Proofsource needs you to stop Zutrix. Your history and reports there stay where they are.
Bring your questions across
Export or copy the prompts you track in Zutrix and add them as buyer questions in Proofsource, so both tools ask the same things.
Run both side by side
Read the two for the same days on your own domain. Where the numbers differ, Proofsource shows the answers and the pages each engine cited, so you can see why.
Keep what serves your team
Many teams keep one tool for reporting and another for fixes. Pick on your own evidence, not on a comparison page.
