Prompting is the whole interface
With a general tool you are responsible for describing the wheel, the finish, the fitment and everything that must not change. TuningLab replaces that with a part you pick from a catalog or right-click on the web.
GENERAL AI / THE FIDELITY PROBLEM
Ask a general-purpose image model to put new wheels on your car and it often returns a beautiful photo of a car that resembles yours. Different mirrors, different badge, different arch line. Close is not the same as yours.

AI car photo editor
ChatGPT and Gemini can both edit an uploaded photo from a text prompt, and both are improving quickly. The gap is not raw image quality — it is how much of your original car survives the edit.

The usual result is a car with subtly different proportions or a redrawn badge. For a wallpaper that is fine. For deciding on a two thousand euro wheel set it is not.
A chat thread gives you a picture. A garage keeps every version of your car in one place, so you can put January’s idea next to March’s and see which one you still like.
FROM CAMERA ROLL TO TUNE BAY
A fair test takes about five minutes.
One clear three-quarter shot, good light, whole car in frame. Changing the input photo changes everything downstream.
Wheels only, nothing else. A single-variable edit is the only way to see which tool preserves the rest of the car.
Check the badge, mirrors, door line, plate and headlight shape. That is where drift shows up first, and it is the whole comparison.
BEFORE YOU PULL IN
Both can edit an uploaded image from a prompt, and for many edits they do it well. Fidelity to the original varies between tools and between attempts, which matters much more for a car you own than for a generic subject.
The prompt is written for you, the part comes from a catalog rather than a description, and the job is always the same one: change this system, keep this car. Narrow scope is the advantage, not a limitation.
Yes — the renders come from an image model. The difference is everything around it: your car stored once, parts as structured input instead of prose, and every result kept in a garage you can compare against.
Sometimes, yes. Treat every render as a styling preview rather than a technical drawing, and re-run it if a detail looks off.
