Proofsource and G2: your rating, straight from the source
Paste a read-only G2 API token and Proofsource reads your star rating and review count from your own G2 account. For software brands, AI engines often cite G2 when buyers ask which product to choose, so tracking your real score beside how engines answer shows whether your reviews are working for you.
