Rendero and PromeAI at a glance
PromeAI offers sketch rendering, image editing and video tools for architecture and other creative work. Its range includes workflows from drawings and images as well as text. Tool counts, promotional allowances and model availability change, so check the current product and plan pages before deciding.

Rendero
- Input
- An architectural image and a specific area to revise, such as a wall finish or planting bed.
- Editing workflow
- Select a scene region, then guide the change with the prompt and reference controls supported by your chosen engine.
- Design review
- Inspect the selected boundary before rendering and compare nearby details afterward. A selection guides the edit; openings and adjacent surfaces can still change.
PromeAI
- Input
- Sketches, photos, model screenshots and text, depending on the tool
- Editing workflow
- Region Rendering with a control image, Erase & Replace, and image/video tools
- Design review
- Compare the generated image with the source design

How credits work
Free accounts receive 50 starting credits once at signup. These credits do not refill each month.
Rendering charges vary with the model, resolution and, for some engines, processing time. Upscaling uses additional credits. The app shows your remaining balance.
Allow for retries and edits when planning a project. A credit balance does not represent a fixed number of finished images.
Choose the editing tool for the task
PromeAI documents Region Rendering, Erase & Replace and Magic Editor. Region Rendering accepts a base image, a selected area and a control image; Erase & Replace uses a selected area and replacement instructions. Its product list separates these from sketch rendering and video tools.
Rendero uses scene segments for selected-area refinement, with prompts and reference guidance. For a facade material change, check that the selected segment ends at the intended corner or window frame. Compare the output with the source at those edges. Having a local-edit tool does not establish a quality advantage for either product.
Include the second edit in your comparison
A first render may be attractive while still needing a material correction. Keep that correction within the comparison: save the starting image, identify the requested finish, and record any retries or cleanup before accepting a version. Compare the edited boundary as well as the overall appearance.
PromeAI's broader toolkit also covers image and video generation. If those are part of the same project, check the allowance for each action rather than treating every credit as one architectural render. For Rendero, plan terms determine available engines and resolutions.
