FairDrawApp's answer:
Content creators, small brands, shops and community managers who run comment-based giveaways on Instagram and TikTok, and who want a transparent way to pick and prove the winner. Mostly Spanish-, Portuguese- and English-speaking audiences.
FairDrawApp's answer:
Every FairDraw giveaway ends with a public certificate that anyone can open and verify, so the winner is never just "trust me". You can draw at random from the comments of an Instagram or TikTok post, or let AI choose the winner by a criterion you write yourself (for example "the funniest comment"). The AI explains its choice, and the certificate shows both the criterion and the explanation.
FairDrawApp's answer:
FairDraw was built by Marshall Angle LLC after seeing that giveaway winners are often questioned in the comments. The goal is a draw that anyone can check: every result comes with a public certificate, and AI selection explains why a comment was chosen.
