AI line-call review: two BWF-approved systems reach smaller tournaments
India's Stupa Sports and Malaysia's Revealtek offer camera-based instant review at a fraction of the cost of traditional systems, according to the companies and press reports.
Stupa Sports (India)
MediaBrief and IT Brief India reported on 20 March 2026 that the BWF has certified the AI-powered Instant Review System of Stupa Sports, a company based in Gurugram. Both say BWF testing found 99% accuracy against a 98% requirement, that the BWF added it to its Equipment Approval Scheme and told its continental confederations it can be deployed. Several high-speed cameras around the court track the shuttle with computer vision and show where it landed, in real time. The aim is smaller and lower-tier events that could not afford review technology.
Reveal Lens (Malaysia)
SAYS and The Star describe the Reveal Lens system by Revealtek, used at the Affin 100Plus Junior Elite Tour Finals in Kuala Lumpur, which ended on 21 June 2026. SAYS says it is one of only four instant review configurations approved by the BWF, that cameras record at 480 frames per second, and that a decision shows live in the hall within seconds. The Star adds that the review is shown on court to prevent tampering and that Revealtek plans analysis tools from September 2026. The Vibes says it sets up in under an hour without fixed infrastructure and quotes its CEO saying comparable international systems can cost over USD 100,000 per tournament; that is a company claim.
What we cannot say
Accuracy and cost figures come from the companies. We found no BWF text on either system and no rule requiring them at any event.
Why it matters
A disputed line call is one of the most heated moments in a match; cheaper review could bring the same fairness to junior and club-level competitions.
