Shine keeps going: a 9 or a 10 is a customer telling you they love you, and Shine turns that moment into a testimonial, quote card, or full case study automatically. Measuring NPS is always free. Paid plans add Slack alerts and CRM sync, let you remove Shine branding, raise survey-send volume, and raise how many promoters you can turn into AI interviews each month; the free plan includes one promoter interview per month so you can see the full loop. ## How NPS is calculated NPS comes from one question — "How likely are you to recommend us?" — answered 0–10. Subtract the percentage of detractors (0–6) from the percentage of promoters (9–10) for a score from −100 to 100. Passives (7–8) count toward the total but not the score. ## Try it Sign up at or talk to sales at . Full product detail:
