You've been racing alone.
Not anymore. SimDriverCoach is with you on every lap — it remembers every corner you've ever driven, and helps you understand what's working, what isn't — how to correct it, and why. The work you put in shows — corner by corner, track by track, season by season.
After every session, you know three things.
What cost you time.
What to work on next.
Whether you're actually improving.
Every lap you drive is recorded and measured, corner by corner — then held up not against a single reference lap, but against everything we know: every run you've ever taken through that corner, your best entry and your best exit there, and the way drivers at your level take it. Your new lap doesn't meet another lap. It meets all of that.
Getting faster.
Development in sim racing is no secret.
Seat time
Nothing replaces laps.
Measured, not felt
Knowing what's working and what isn't.
The right thing
Not everything at once.
Long enough
Staying at it until the work shows.
On your own, all of this runs on trial and error — guessing what to change, guessing whether it worked. That's exactly what we take out.
Two ways in.
One goal — understanding your driving. How you get there is your call.
See what you're doing.
Open a session and it's already laid out — the answer written, every corner measured, your references drawn on the charts. Nothing to configure, nothing to build. However deep you want to look, it's already prepared.

The chat runs on your own Claude Code, right inside SimDriverCoach. It's not a help bubble, it's a second cockpit: it draws the charts into the conversation, runs a live pit board, plans your race week, keeps notes with the data attached, and even tunes your sim settings with you.
No two drives are alike.
iRacing produces a staggering amount of data — and data without context can give the wrong answer. Track temperature. Traffic ahead, pressure behind — or a free run. Practice, quali, race — or just fun. We judge every lap in its context:
Traffic isn't pace.
A damaged car changes what a good lap means.
Practice, quali and race ask different questions.
Same telemetry. Different context. Different answer.
What we mean by "coach"
There's a coach in our name, so let's be straight about it. A real coach — one who grew up on race tracks — is irreplaceable. He leads: owns your development, keeps the agenda, brings back the things you'd rather avoid. He minds the driver, not just the driving. No AI can be that. And maybe it doesn't have to be.
Because few coaches have ever had what this one has: this much of their driver, measured — every lap, every corner, every season. And we might just read the telemetry more thoroughly, too.
SimDriverCoach walks beside you. After every session it tells you what happened, what worked, what didn't — how to correct it, and why. It follows your trends — knows where you are, how you got there, and what needs work next. And together, you can shape that into a plan.
Walking ahead — leading on its own: owning the plan, holding the course through the weeks, bringing you back to it when you drift. Until it leads, we won't claim it does. We can see the road from here — and we're on it.
No false certainty.
One rule above everything: we never claim more certainty than the data has earned. When a conclusion doesn't survive the evidence, we withdraw it. "We don't know yet" is an answer you will actually see here.
Where we are
SimDriverCoach is in active development. Here's the road to launch.
Closed beta
Inviting a small group of pilot drivers. (We are here.)
Expanding the beta
More drivers, still invite-only, as we harden the product.
Public beta
Open sign-up for everyone to try.
Full launch
Paid plans go live alongside the free tier.
Free during beta — pay only for AI
Free during beta — telemetry capture, visual analysis, cloud sync and leaderboards, all free.
AI analysis is pay-as-you-go — you only pay for what you actually use. No subscription, no commitment.
The conversation, on your own Claude Code. Your Claude plan is billed by Anthropic; the connection is ours. Free during beta.
Anonymous averages, both ways — your sessions feed anonymized averages into the pool, and you see how your iRating range drives the same corners. During beta, taking part is the deal for everyone. Nothing identifiable is ever published unless you share it yourself. How it works →
Doc's turn.
So far, most of the work went into the foundation: the engine that builds every lap, and the processing that turns raw telemetry into data Doc can trust from every angle. Very little of it went into Doc himself — and we think he's already very good. With the groundwork in place, he gets the time now.
Installs and runs, everywhere
SimDriverCoach installs cleanly and runs reliably on every driver's PC.
Doc, further
More of what he knows, how he reads your data, and how he explains it.
The small things
Small bugs fixed, and the screens made smoother to use.
Every lap is assembled live, as you drive it; the telemetry file iRacing writes afterwards only adds detail. So the same foundation could talk to you during a session. That isn't where we're going now — if drivers ask for it, the engine is ready to build on.
During the beta, keep your IBT files and leave the telemetry in the database: the analyses are still growing, and they read the full data. The final version brings data management: a backup wizard — a snapshot to your network, or to your own cloud backup — and a database that slims itself.
Our recommendation: slim it after every season. The base telemetry of every lap stays — time, distance, speed, throttle, brake, steering, gear, rpm, position — plus the statistics of everything else. That is what Doc reads when he looks back, so his answers about past seasons stay practically the same.
The math. An hour of driving takes about 580 MB today: 220 MB of IBT files and 360 MB in the database. Slimmed, the same hour is about 16 MB. A season of 50 hours: about 29 GB today, under a gigabyte slimmed. Ten years of seasons, slimmed, come to about 32 GB — about what a single season takes today.
