RallyIQ

RallyIQ puts a tennis scouting desk inside ChatGPT. It is built on the Match Charting Project, where volunteers have recorded every shot of more than 11,000 professional matches: serve direction, stroke, direction, return depth and how each point ended. RallyIQ turns those charts into a model of what each shot is worth, so it can say not only what a player does but what it gains them.

Ask for a game plan and get a forecast with a 90% range, where to aim first serves on each court against that returner, which returns work against that server, the rally shots to favour and avoid, and the charted head-to-heads. Ask about one player for serve and return strength against an average opponent, shot ratings for direction choice and execution, first-serve habits on break points, how readable the serve is, and the shots they are most exposed to. Ask why a charted match went the way it did and get each player's gains and leaks by stroke and by set. Leaderboards rank players on direction choice, execution, serve exploitability and long rallies.

Every number comes with its uncertainty and a link to the full page on RallyIQ. The shot data is licensed CC BY-NC-SA 4.0 and every answer credits the Match Charting Project. Every tool is read-only and no account is needed.
