Your AI race engineer. Measured, not guessed.

After every session, Camber opens the telemetry your sim saves on your PC (Assetto Corsa EVO, Le Mans Ultimate or iRacing), finds where you lose time and the likely reason, and works out setup changes with you, one change at a time.

Lap 3 · Ascari · 0.4 s lost · late braking, front-left lock-up

The front left keeps locking into the chicanes and lap 3 was a mess. Is it the car?

Engineer

A bit of both, and they are separate problems.

Driving · lap 3

At Ascari you braked 18 m later than on your clean laps and locked the front left: 138 km/h at the apex instead of 178, 0.4 s lost. That one is on you. measured

01How it works

Drive. Read the numbers. Talk it through.

Camber is a desktop app that works after the session, on the files your simulator has already saved. It never touches the game while you drive.

  1. Drive

    The session lands on its own

    Assetto Corsa EVO saves MoTeC files; Le Mans Ultimate and iRacing save their own telemetry, which Camber converts to MoTeC. Camber watches those folders and lists each new session, with its best lap, as soon as it appears.

  2. Measure

    Camber does the maths

    Runs split at pit stops, sectors, your ideal lap, driving errors corner by corner, balance, aero platform, dampers, pace and fuel. All computed on your PC from the file, not estimated by an AI.

  3. Ask

    Your engineer explains

    Add the session to a chat and ask. The AI engineer reads Camber's numbers, tells you what is measured and what is a hypothesis, draws charts from your data and asks when something is missing.

  4. Apply

    One change, your approval

    In Assetto Corsa EVO the engineer can prepare the new setup file for you: nothing is written until you press Approve, and every change can be undone. In Le Mans Ultimate and iRacing it gives you the exact values to set in the garage.

Everything a track engineer looks at.

The panels below are drawn the way Camber draws them. The values are examples.

Compare laps like in MoTeC

Speed, throttle and brake on a common distance axis, up to four laps, zoomed on any corner. Ask for it in plain words; Camber draws it from the samples in your file.

An engineer who remembers

What you learn about a car and a track is kept as short notes on your PC. The next chat starts from them. You can read and edit every note.

  • N4F2004 · Monza Rear tyre pressures climb about 1.5 psi over the first 3 laps.
  • N7F2004 · Monza Fuel costs about 0.02 s per litre per lap.

A/B tests that add up

Camber spots two runs on the same car, track and road temperature with different setups, and puts the numbers side by side. You confirm and rate; trends build up over time.

03Simulators

Three sims today. More to come.

Every session ends up as a MoTeC file, so the same analysis, charts and engineer work the same way in every sim. The converted files open in MoTeC i2 too.

MoTeC files from the game

Assetto Corsa EVO

  • Reads the MoTeC files the game saves
  • You pick the setup you drove for each run
  • The engineer can edit your .carsetup files, after your Approve

Own telemetry → MoTeC

Le Mans Ultimate

  • Reads the game's own telemetry and converts it to MoTeC
  • The setup you drove is read from the telemetry: nothing to assign
  • Tyre wear and hybrid energy included

.ibt → MoTeC

iRacing

  • Reads the .ibt files and converts them to MoTeC
  • The setup you drove is read from the telemetry: nothing to assign
  • Turn on disk telemetry in iRacing (Alt+L in the car)

More simulators are planned. Camber does not edit Le Mans Ultimate or iRacing setup files: the engineer tells you what to change.

04How the AI part works

Camber computes. The AI reasons. You decide.

The heavy lifting on your telemetry happens in the app, on your PC. The AI gets a text summary of those numbers, and does what an engineer does with them: explain, question, propose.

01

Camber, on your PC

  • Reads your sim's telemetry (converted to MoTeC for LMU and iRacing) and your setups
  • Computes runs, sectors, ideal lap, errors, balance, dampers, pace, fuel
  • Draws every chart from the samples in your file
  • Writes an AC EVO setup file only after your Approve

02

The AI, at your provider

  • Reads Camber's summary, never the files themselves
  • Explains what the numbers mean for you and the car
  • Keeps measured facts apart from hypotheses, and asks when data is missing
  • Proposes one change at a time, and a way to test it

03

You

  • Choose the AI provider and the model
  • Choose which sessions go into each chat
  • Approve or reject every setup change
  • Confirm and rate each A/B test

Your PC

Your sim MoTeC files Camber

Files, setups, chats, notebook and your key stay here.

Your AI provider

Anthropic · OpenAI · Google Gemini · OpenAI-compatible

Bills your account for the tokens used, under your terms with them.

Camber's author

No account, no server between you and the AI. Only an anonymous daily count of answers per model, which you can turn off in Settings.

Bring your own key

An API key is a password that lets an app use an AI provider on your account. You create one on the provider's site, paste it in Camber's Settings, and it stays on your PC.

A chat subscription such as Claude Pro or ChatGPT Plus is not an API key: API use is billed separately by the provider.

Tokens, in plain words

Providers bill by the token, a piece of text of three or four characters. You pay for what goes in (your question, the summaries, the conversation so far) and for what comes out (the answer).

A session summary is 16–37 KB of text in the sessions tested so far, roughly 5,000–12,000 tokens. Camber shows the exact count under every answer; your spend is on your provider's dashboard.

Pick the model

Camber lists the models your account can use and suggests three: recommended (balanced, the default), most capable and fastest. Bigger models reason deeper and cost more per token; you can switch per chat.

05Your data

Who sees what. All of it.

Your telemetry, setups and chats go to one place: the AI provider you set up. Camber itself only gets an anonymous daily usage count, which you can turn off. Here is everything it handles, and where each piece goes.

WhatOn your PCSent to your AI providerSent to Camber

06FAQ

Before you install.

Ten answers, from what Camber reads to the warning Windows shows when you install it.

Does it read live telemetry while I drive?

No. Camber works after the session, on the files your simulator saves. It never touches the game while it runs.

Do I need to pay for the AI?

You need an API key from Anthropic, OpenAI, Google or an OpenAI-compatible service, and the provider bills API use to your account. A chat subscription such as Claude Pro or ChatGPT Plus does not include API use.

How much does a chat cost?

It depends on the provider, the model and how much you send. A session summary is roughly 5,000–12,000 tokens, and every message re-sends the conversation so far, partly from cache where the provider supports it. Camber shows the tokens of each answer; the money is on your provider's dashboard. Faster models usually cost less per token.

Can I see exactly what was sent to the AI?

Yes. Under every message, View data sent shows the summaries, setups, notebook and garage that went with it.

Does Camber train an AI on my data?

No. Camber never receives your chats, telemetry or setups: only an anonymous daily count of AI answers per model, which you can turn off in Settings. What you send to your provider follows their terms: check whether your plan allows them to use it.

Will it change my setups on its own?

No. Camber edits setup files only in Assetto Corsa EVO, and each change waits for your Approve, with before and after shown. In Le Mans Ultimate and iRacing it never touches your setups: the engineer tells you the values to set. You can turn on automatic approval in Settings; it is off by default. Every applied change keeps a backup and can be undone.

Which simulators, cars and tracks?

Assetto Corsa EVO, Le Mans Ultimate and iRacing, with any car and track they record; more simulators are planned. When it edits an AC EVO setup file, Camber changes only the fields it has verified and leaves the rest of the file byte for byte.

Does it work without internet?

Sessions, runs, laps, the notebook and the test log work offline. The chat needs a connection to reach your AI provider.

Windows says “Windows protected your PC”.

The installer is not code-signed yet, so SmartScreen warns about it. Choose More info, then Run anyway. The installer runs for your user only and needs no administrator rights.

What do I need?

Windows 10 or 11 (64-bit), at least one of Assetto Corsa EVO, Le Mans Ultimate or iRacing (with disk telemetry on), and an API key from one of the supported AI providers.
