What is Proofsource?
Be the Brand AI recommends.
Proofsource is an AI search visibility platform that shows whether ChatGPT, Claude, Perplexity, and Google AI Overviews mention your brand when buyers ask real questions. It reports your mention rate, share of voice, and average position per engine, shows which competitors get mentioned instead and why, and maps the reviews, lists, and discussions each AI engine trusts.
Its AI agents then draft fixes ranked by expected lift versus effort; once you approve, they publish the fixes and verify whether AI answers change. Pricing is freemium: a free trial (200 answers, 25 prompts, 4 engines, 2 days, no credit card), Custom plans from $64 per brand per month with all 10 engines and daily monitoring, and a fully managed option. Available as a web app with a REST API on Custom plans.
