The short answer
You can keep the picture and swap the words. On your phone:
- Open MOJIKUI and paint over the words you want gone, then tap Erase text.
- Choose where it’s going:
- Print it (flyer, menu, poster) → Make print data
- Post it (Instagram, Facebook, website) → Use as banner, which opens Banner Pop
- Type your own words and style them.
- Export.
MOJIKUI erases; it doesn’t translate or rewrite. You choose the new words and type them.
The new words are real type from a font, not letters drawn by the AI, so they come out exactly as typed and you can change them again later.
When you’d want this
- The AI put placeholder or generic words on the sign (“COFFEE SHOP”, “SALE”) and you need your shop’s name and this week’s offer.
- You made a flyer in English and need the same picture with Spanish (or other) wording for part of your community.
- The words are right but you want to change them every week without regenerating — and getting a different picture.
If the problem is misspelled or garbled letters (“HAPPY BRITHDAY”), see ChatGPT image has garbled text?. The steps overlap; that guide focuses on fixing bad letters, this one on putting different words in.
Need to know what the image says first?
If the picture has text in a language you don’t read, the Translate app on iPhone can translate text in a photo from your library: open Translate, tap Camera, then choose the photo (Apple Support: Use the camera in the Translate app).
Treat that as a way to understand the image. For the words you’ll actually print or post, write them so they sound natural to your readers rather than pasting a word-for-word translation.
1. Erase the words in MOJIKUI
Open MOJIKUI and choose the image (PNG, JPEG or WEBP).
- Paint over the words with your finger. The Brush slider changes the size.
- Undo if you painted too much.
- Tap Erase text. Banners and buttons keep their shape; only the text is erased.
Anything you don’t paint stays. A decorative “OPEN” or a logo-like word can stay while the message changes.
Your image isn’t uploaded; the erasing runs on your device. The first time, the eraser itself (about 10 MB) is downloaded.
2a. Printing? Tap “Make print data”
You’ll choose a paper size — switch units to inches for Letter, Tabloid, 4x6, 5x7 or posters from 12x18 to 24x36 — and the editor opens with your cleaned image as the background. Tap Text, type your words, drag them into place, and add an outline, 3D, metallic or glitter style. Export a PNG or JPG for a home printer or a print counter, or a print-ready PDF.
2b. Posting? Tap “Use as banner”
Banner Pop opens with your cleaned image as the background, at the size closest to the image’s shape. Change it to a square or another size under Export → Image size. Then tap Text, type, pick a Font, add a Style, and export a JPEG or PNG.
About fonts and other languages
You can type anything, but a font can only draw the letters it contains. The fonts in Banner Pop cover English and Japanese, and some (the script fonts, for example) are letters only.
If you’re writing in Spanish, French or another language with accents, type the full text and check every letter. If a letter doesn’t appear, that font doesn’t have it; pick a different font. For alphabets beyond those, check before you commit to a design.
Three tips for new words on an old picture
- Fit the space. New wording is rarely the same length. Shorten it, or split it into two lines, so it fits where the old words were.
- Match the mood. Heavy block letters in the original call for a heavy font; thin elegant lettering for a serif or script. Taking one color from the picture for your text helps it look like it belongs.
- Outline for readability. On a busy picture, a white or dark outline around the letters keeps them readable from across a room.
Not sure which style fits? Type your words into the text effect templates and compare them side by side.
Before you start
- MOJIKUI is made for AI-generated images. Photos and hand-drawn art may not erase cleanly.
- Very large text (about half the image) can leave a visible patch.
- Don’t use it to remove logos, watermarks or copyright notices, or any mark a rights holder put there. Use images you have the right to use.
FAQ
Can I change the words in an AI image without changing the picture?
Yes. Erase them in MOJIKUI, then type new words in the editor or Banner Pop.
Does MOJIKUI translate the text?
No. It only erases. To read text in another language, the iPhone Translate app can translate text in a photo from your library.
Can I put the words in another language, like Spanish?
Yes, as long as the font has the letters. Type the full text and check every letter; switch fonts if one is missing.
Can I keep some of the original text?
Yes. Only what you paint over is erased.
