Where each shines

- Google search signals in the same tool. Featured snippets, People Also Ask, autocomplete and AI versus Google demand sit next to the AI audit.[1]
- Many brands per plan. From 5 brands on Starter to unlimited on Enterprise, with extra brands and audit packs sold as add-ons.[1]
- Page reviews and ad monitoring. Technical reviews of individual pages for AI readiness, and ChatGPT ad result searches in the US on Professional and Enterprise.[1]
Where Proofsource shines
- Four engines from day one. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews from the trial up. Brand Auditor's entry plan reads ChatGPT, and its top plan reads four.
- Claude is on the panel. Brand Auditor's FAQ lists ChatGPT, Google AI Mode, Gemini and Perplexity, without Claude.
- Daily, with intervals and drafted fixes. Daily re-reads on Custom with a 95% Wilson interval on each share, where Brand Auditor's Starter is built around manual audits, and each gap comes with the pages cited instead and a draft held for approval.
