Questions, answered
A few things worth knowing.
Straight answers before you upload a photograph.
Is the preview an exact picture of the finished work?
No. It is an illustrative concept. Preevu asks the AI to retain the viewpoint and unrelated details, but it can still change small features, colours or proportions. Confirm real materials with samples and the installation details with the relevant professional.
Which trades can use it?
Preevu covers driveways, roofing, flooring, decorating and landscaping. The visualiser shows the active trades, changes and finishes managed in the catalogue.
Do I need an account to upload a photo?
You do not need a customer account to use the public visualiser. Open the tool, upload a supported photograph and choose the work. Generation availability is subject to the service’s configured limits.
Can I use it on my phone?
Yes. The visualiser works in a web browser on a phone, tablet or computer. Use a JPG, PNG or WebP image within the upload limit shown in the tool. Convert HEIC photos to a supported format first.
What happens to my photograph?
The photo and relevant instructions are sent to OpenAI to produce the requested image. Preevu stores the original, result and generation details so you can view the preview and the administrator can manage it. Read Privacy & your photos before uploading.
Does it write a quote or calculate measurements?
No. Preevu produces a visual concept. It does not measure a project, calculate costs, create a construction drawing or confirm technical suitability.
