Meet Immersa
Immersa brings a race engineer into your game, turning live race data into radio calls that fit what is happening on track. It was built for immersion, with responses quick enough to feel like part of the race.
Time-sensitive calls come from a deterministic engine. Install the optional local Qwen model to add open-ended banter and more natural conversation. Together, they give your engineer both the pace and personality of a real pit wall.
Everything runs on your computer. Once the app and any optional model are installed, you can race offline with no API keys, usage fees or subscription.
Race awareness
Your engineer knows when your car is the underdog. Passing a faster car deserves a different reaction from a routine overtake, so the call reflects how hard you had to work for the position.
It follows the battle after the pass too. If you lose the place and take it back, the next call remembers what happened. Race starts, contact, safety cars and wins all get responses that fit the moment.
Turn coaching
Lap and sector times tell you how fast you were, but a slow sector can still leave you guessing where the time went. Immersa goes further with feedback for individual turns.
Your engineer points out the corners and straights where you gained or lost pace. That gives you a specific place to work on next lap instead of asking you to improve an entire sector at once.
Race strategy
Your engineer considers an undercut, an overcut, or covering a rival's undercut as the race develops. It looks at the situation before suggesting a stop, rather than giving you the same pit call every time.
When the choice depends on how the car feels, you get a say. It may ask if you can keep up the pace on worn tyres or whether a stop under the safety car is worth the risk when the answer is not clear.
Your engineer
Choose from 11 original race engineers from different nationalities. Each one has a distinct voice and personality, so changing engineers changes the feeling of the radio as well as the sound of it.
You can shape any of them with mannerisms inspired by famous real-life race engineers. Choose standard communication or keep it concise with facts-only calls when you want the radio to get straight to the point.
More than 2,700 voice lines cover different race moments. You may hear a familiar line again, but the range is there to keep repeats to a minimum and make the radio feel less predictable.
Race banter
Install the optional Qwen model if you want to talk to your engineer beyond the usual race calls. You can joke around, vent about a messy battle, or even tell them the driver ahead is an idiot and hear what they have to say back.
It adds room for a more personal conversation when the race gets heated. The model is an optional download, so you can choose whether you want that extra back and forth.
