Human-controlled AI
An assistant for the golfer and the society organiser
4left will use its deep history to prepare useful work—not to make unchecked decisions. Handicap maths, permissions and final writes remain deterministic and under user control.
Run a society day
Draft events, reminders, balanced groups, tee sheets and result summaries for organiser approval.
Keep courses current
Identify stale course and hole data, attach sources and propose updates without silently overwriting history.
Capture a scorecard
Turn a scorecard photo into a validated draft that the golfer reviews before anything is recorded.
The operating rule
AI can retrieve, explain, draft and propose. People approve anything that sends, publishes or changes a score.
