Overview
Four days before launch, Perplexity switched its default answer to a rival. Nordvik had it back before the press release went out.
The challenge
Nordvik had timed a major feature launch to a category where it owned the AI recommendation. A rival's fresh (and partly inaccurate) comparison post flipped Perplexity's answer right before the campaign.
The solution
The hourly drop alert fired Tuesday morning with the exact diff and the driving citation. Nordvik published a corrected, source-linked comparison the same day and requested re-evaluation on the cited review thread.
The results
The answer flipped back in 72 hours. Launch week delivered Nordvik's highest AI-referred signup count ever — and the rival's inaccurate post now cites Nordvik's correction.
