How do I add text or logos onto a building image?

You can ask for signs or lettering in your prompt, or use Select and Modify to add them to an area of the image, but AI often spells words or draws logos imperfectly. For exact text or a real logo, add it afterwards in an image editor or presentation tool, where you control the result.

You can try, and short signs often work. For exact text or a real logo, the safest way is to add it after you generate.

Try it in Rendair

  • Add it to your prompt, for example "a sign above the entrance reading CAFE".
  • Use Select and modify to mark the area, such as the wall above the entrance, and describe the sign.
  • Keep the text short. Long words and small letters are less reliable.

Check the result

AI can misspell words or draw letters in the wrong shape, and it usually cannot reproduce a real logo exactly. Always read the text carefully before you show it to a client.

For exact text and logos

Generate your render without text, then place your text or your logo on top with an image editor or a presentation tool. This gives you full control over the spelling, the size and the brand colors.
