Proofsource

Proofsource is an artificial intelligence intelligence platform that tracks brand mentions, competitor rankings, and source citations across multiple generative engines.

Proofsource is an artificial intelligence intelligence platform that shows which buyer questions name specific brands in ChatGPT, Perplexity, Claude, and Google AI Overviews. It operates by asking buyer questions to top artificial intelligence engines, recording whether brands are named, and identifying competing brands and cited sources. The platform is designed for growth leaders, writers, search teams, agencies, and founders who want to manage their brand presence in generative search. It sets itself apart by providing a complete loop from answer measurement to source tracking, error detection, and content fixes. Users input their website, approve tracked questions, and review engine responses, competitor leaderboards, and confidence intervals.
