When should I use image-to-image instead of text-to-image?
Use an image as your starting point whenever you have one, such as a sketch, a plan, a photo or a view of your model. Rendair then keeps your design and adds the look. Use text to image when you have no input yet and want to explore ideas. Text to image with Rendair v1 costs no credits.

Choose by what you have in your hands. If you have a design, start from it. If you only have an idea, start from words.
Use an image as the input
Choose an image tool when you have a sketch, a plan, an elevation, a photo or a view of your 3D model. Rendair keeps the composition and the geometry of your image, and your description adds the materials, the light and the mood. The result matches your design.
Tools: Sketch to Render, Elevation to Render, Floor Plan to Render, 3D Model to Render and Image to Render.
Use text to image
Choose Text to Render when you have no image yet and want to explore ideas, moods or concepts. The result is a new invention every time, so it is good for inspiration and early exploration.
Combine them
Many designers start with text to explore ideas, choose one they like, and then use that image as the input for a more controlled render.
Credits
Text to image with Rendair v1 costs no credits, so it is a good place to experiment. Other models and tools use credits, depending on the model and the resolution.
