Nestor v0.2.0

Fixes from rig testing at Long Beach, plus a way to send us a debug bundle.

Install / upgrade

Download Nestor_0.2.0_x64-setup.exe (or the .msi) below and run it. Your laps and chats (in %APPDATA%\SimCoach) and your API key (in Windows Credential Manager) live outside the install folder, so installing over 0.1.0 keeps them. Windows SmartScreen still warns (not code-signed yet): More info → Run anyway.

What's new

• Export a debug bundle: zip up a session from the Sessions screen and attach it to a bug report (#267).
• The app starts blank when there's no live session, with a button to open past sessions, instead of reloading the last session's laps and map (#280).
• LMU's menus read as "no session": the app no longer shows your previous session while you sit in the menus. A paused game still counts as live (#282).
• The live lap is readable from its first metre, so "I spun out" or "who hit me?" on lap 1 works before the lap finishes (#279, #276).
• "Who hit me?" names the nearest same-class car on the lap you're driving (#250).
• Long Beach: T3 is the fountain's left exit; corner direction now comes from the map, not one lap's steering (#269).
• Wheel damage: a detached wheel is now reported as confirmed (#285).
• Errors say why: an API failure mid-answer stops the spoken half answer and tells you the reason, e.g. an expired key (#259, #256).
• Grounding: names like O'Brien are checked properly (#258).

Known issues

• A spin can take ~20 s to show up while the car is still stopped after it.
• The status can read "LMU Offline" in LMU's main menu.

Nestor v0.1.0

First public release of Nestor, an AI sim-racing coach for Le Mans Ultimate.

Nestor captures your laps live from LMU's shared memory. You ask it questions in plain English, either between sessions or mid-race over push-to-talk, and it answers from your own telemetry. Code measures everything: corner speeds, brake points, time loss by corner, incidents, positions and gaps. The AI only narrates those facts. It never guesses a corner, a delta or a gap.

Install

1. Download Nestor_0.1.0_x64-setup.exe (or the .msi) below and run it. Windows only.
2. Open Settings → AI / Coach, paste your own Anthropic API key and pick a model.
3. Start LMU and drive. Laps are captured automatically.

Windows SmartScreen will warn you. The installer isn't code-signed yet. Click More info → Run anyway. Signing is in progress.

Bring your own key. Nestor has no server and no account. The coach calls the Anthropic API directly with your key, which is stored in Windows Credential Manager. A typical question costs a few cents, and a full race debrief can cost around a dollar. The chat screen shows a running cost meter.

What's in it

• Lap and corner coaching: per-corner metrics against your best lap, where you lose time, and your consistency, car balance and inputs.
• Race awareness: position, gaps, the class leader and the fastest lap in your class, the cars around you on track (including who's lapping you), fuel, energy, tyres and pit window, and incidents on the lap you're driving.
• Voice (optional): push-to-talk from a wheel button, speech-to-text on your own PC, and answers read aloud.
• Corner maps for 17 tracks, plus an in-app editor for building more.
• History import from LMU result logs.

Known issues

These have been fixed but not yet checked at the rig. Please report what you see:

• "Who hit me?" on the lap you're still driving
• "I lost it" after a spin
• the Long Beach T2 corner direction (#269)
