Find your
perfect lap

Compare iRacing laps side by side, understand every input, and see exactly where the next tenth is hiding.

Hotlap.ai turns iRacing telemetry into clear braking, throttle, steering, racing line, and consistency feedback. Free on desktop and web.

iRacing telemetry,
made actionable.

Overlay any two iRacing laps and see exactly where time is gained or lost. Brake points, throttle application, steering inputs, racing lines, tire data, and delta traces are synchronized so you can turn raw sim racing telemetry into faster decisions.

  • Automatic telemetry session library
  • Distance-aligned delta analysis
  • 3D track map with AI markers
  • Sector-by-sector breakdown
  • Throttle, brake, steering, and tire traces

How Hotlap.ai finds the next tenth

Most sim racing telemetry tools show graphs. Hotlap.ai connects the graphs to driver decisions. It helps iRacing drivers understand whether time is being lost from brake points, peak brake pressure, trail braking shape, throttle timing, steering overlap, apex speed, gear choice, upshift timing, understeer, oversteer, or inconsistent line through a sector.

Sync iRacing telemetry

The desktop app scans Documents/iRacing/telemetry, groups sessions by car and track, hashes files for duplicate detection, and recovers interrupted upload jobs.

Compare against a faster lap

Overlay your lap against a personal best, theoretical best, teammate, live lap, or community reference. Delta, brake pressure, throttle, steering, gear, RPM, tire data, and map position stay aligned by distance.

Turn data into AI findings

AI analysis grades every corner from S to F, ranks the sections costing the most time, and shows your numbers against the reference — apex speed, brake point, throttle pickup — so each finding is backed by evidence.

Coaching that names the corner

Not "improve your braking." The exact turn, the exact input, and what it costs you. Every finding links back to the traces.

Section 4.91 · ~4907mC-

Braking too late, too softly

Reference applies 41% brake pressure at the start of the zone. You apply 4%, run deep, and compromise the exit onto the front straight.

Section 57 · ~5702mC-

Throttle pickup timing

You went to throttle 25m earlier than the reference, but the eager ramp did not translate into a gain. Build to full throttle later.

0.474s lost at corner 10
Section 37 · ~3668mA

Turn-in: a strength

You turn in 87m earlier, carry 4.1 km/h more apex speed, and gain 0.287s. Keep this rotation approach for similar high-speed corners.

Every lap builds
your driver profile.

Hotlap.ai turns your analyzed laps into a skill profile: each fundamental — brake point, throttle application, turn-in, apex gear, minimum corner speed — is graded and split into strengths and the things to work on next. A driving style radar reads your telemetry across corners and names your archetype, so the AI coaches you within your style instead of against it.

  • Per-skill grades built from real corner evidence
  • Clear split between strengths and what to work on
  • Driving style radar with your archetype, from late braking to smoothness
  • Style-aware AI coaching that works with how you drive
  • Skill trends that show whether practice is paying off
  • Shareable on your public driver profile

AI racing coach, telemetry analyzer, and lap comparison tool in one app

Hotlap.ai is designed for drivers who want a direct answer after every iRacing session: where did the lap time go, what input caused it, and what should I change next? The platform combines telemetry traces, track maps, community references, and AI explanations without hiding the raw data serious drivers still need.

For iRacing practice

Find repeatable braking markers, compare best sectors, and learn why two laps with similar lap times feel different through the same corner.

For race preparation

Review tire behavior, compare previous laps, check consistency across a stint, and identify where conditions or traffic changed your rhythm.

For community benchmarks

Use leaderboards and reference laps to understand what faster drivers do differently in each car and track combination.

For driver improvement

Turn every session into a focused practice plan instead of guessing whether setup, line, brake release, or throttle timing caused the gap.
