GAME. SET. INSIGHT.
Khel.ai calls the lines, reads the serve and rebuilds every rally on clay, hard and grass, so coaches and chair umpires work from the same tracked point.

Built on the sport, not bolted on to it
Ten calibrated cameras triangulate the bounce on baselines, sidelines and service boxes, with foot-fault and net-cord let detection running on the same feed.
Speed is read from the tracked trajectory, then logged with contact height, toss drift and landing zone, so a coach can see where the T serve is slipping.
Each point is cut into serve, return, serve plus one and the rally beyond, with court position, shot count and the stroke that finally ended it.
Bounce behaviour is modelled per surface, so a clay kick, a hard court skid and a low grass bounce are read as themselves rather than averaged into one figure.
How a tennis fixture becomes data you can act on
Court lines, net height at the centre strap and the day's surface are surveyed once, so the model knows the exact court before the first serve.
Ten shuttered cameras genlocked on the court rig record both ends at 340 fps, under floodlights or in direct sunlight.
The ball is followed through toss, contact, net crossing and bounce, and every strike is classified as slice, topspin, flat, volley or smash.
The call reaches the chair umpire's tablet and the stadium speaker in under half a second, and the tagged point lands in Takneek for the coach.
One ecosystem, three levels of the game
A baseline camera and a laptop give a club serve speeds, rally counts and clipped points in the Takneek app the same evening.
A four-camera portable unit that rolls onto any practice court, calling lines for squad match play and logging every serve and rally as it happens.
A permanent ten-camera install running live electronic line calling, feeding serve and rally graphics to the broadcaster and archiving every point.
Each figure is measured against a surveyed reference rig at your venue, then re-checked whenever the cameras move.
What federations, clubs and academies ask us about tennis
Yes. The tracked bounce is reconstructed next to the physical mark, so the chair umpire can compare both on the tablet before confirming a call. Mark reconstruction is recalibrated after each watering and rolling of the court.
The same ecosystem, tuned to a different game
Choose one of your courts. We will survey it, run a live fixture on K-BOX Tennis or Khel Pro Tennis, then leave you the tracking data before you commit to anything.
