WHY RACE LOG

A whole session in,
and all you’ve got is “felt okay”?

Drive on feel and progress comes down to luck; you make the same mistake in the same corner, lap after lap, never seeing it. Race Log turns every brake, every line, every throttle input into numbers you can actually read and act on.

ON FEEL

“T3 felt kind of off… I think?”

“The last few corners didn’t flow, but I can’t say where.” “Felt a bit quicker than last time… maybe?” “T3 was awkward again, I’ll sort it next time.”

× Don't know where the time went
× Not sure the brake points are right
× Progress is just guesswork
VS
ON DATA

Exactly how much
each corner costs you

“T11 lost 0.56s, T1 lost 0.48s, T8 lost 0.48s.” Ranked by what matters most, so you claw back the biggest corner first.

T11Turned in early, braked too hard+0.56s
T1Late back to throttle on exit+0.48s
T8Apex off by 0.5 m+0.48s

Race Log turns “felt okay” into
T11 lost 0.56s, entry speed down 12 km/h.”

COACH · AN AI COACH FOR EVERY CORNER, ACROSS EVERY DIMENSION

No jargon you can’t use —
your AI coach tells you where the time is, in plain words

The Race Log AI coach is your co-driver, not a chatbot. One dataset: the coach explains it, you see it for yourself — when every angle lines up, you can trust it.

stacked to see the gap

Race Log dual-video: same corner best lap vs current lap stacked

AUTO-DETECTED · 14 CORNERSRace Log real track top-down: T1-T14 numbering / S/F start-finish / 80km/h chip / 4-color sectors
GPS · THE ALGORITHM FINDS THE CORNERS

No preset maps,
no marking the start line,
the algorithm does the dirty work

No preset mapsThe algorithm reads the racing line and start line straight from GPS data — works at tracks you’ve never run.
No marking the start lineStart/finish is detected automatically and aligned with the track’s timing loop, so lap times match the official clock.
High-precision corner detectionEvery corner is split into entry / apex / exit, so time gains and losses are pinned to the phase, not just the lap.
