Proofsource or MentionBird: the fair verdict
MentionBird is good value if ChatGPT and Gemini cover your buyers, and its keyword and citation views show what AI reads.
Proofsource fits better if Claude, Perplexity and Google AI Overviews matter from day one, and if each figure should carry its margin of error and each gap a drafted fix.
