AI image generators turn a text description into a picture. They are useful for illustrations, social media posts, presentation slides and thumbnail ideas, and several have free options.

Well-known options

  • ChatGPT: can create images from a description in the chat, with limits on free use.
  • Google Gemini: can generate images in the Gemini app.
  • Microsoft Designer / Copilot: image creation with a Microsoft account.
  • Canva: AI image features inside the designer, so you can drop results straight into a flyer.
  • Adobe Firefly: designed with commercial use in mind; free credits with an Adobe account.

Tools and free plans change often. We name well-known tools that work in Ghana at the time of writing, without prices, because plans and limits are updated regularly.

How to write a good image prompt

Describe: subject + setting + style + mood + format.

A smiling Ghanaian woman selling tomatoes at a busy Kumasi market, bright afternoon light, realistic photo style, wide horizontal image.
  • Add a style: “flat illustration”, “watercolour”, “3D render”, “photo”.
  • Say what you do not want: “no text”, “plain background”.
  • Generate several and pick the best.

Tips for better results

  • Add text later in Canva; AI tools often misspell words in images.
  • Check hands, faces and logos for strange details.
  • Use the right shape: square for Instagram, tall for Status and Reels, wide for YouTube thumbnails.

Rules to follow

  • Check the tool’s terms before using images commercially.
  • Do not create realistic images of real people, or fake news photos.
  • Be honest in advertising: do not use AI images that misrepresent a product you sell.
  • Do not copy brands or other artists’ work.

Common questions

Can I use AI images commercially?

It depends on each tool’s terms. Many allow commercial use on paid plans; some free plans have limits. Check the terms before using images in ads.

Why do AI images get text and hands wrong?

Image models still struggle with small details like text, hands and logos. Add text afterwards in Canva instead.

Can I make images of real people?

Avoid it. Creating realistic images of real people without consent can be harmful and may break the tool’s rules and the law.

Which tool is easiest?

Canva and the image features in ChatGPT or Gemini are the easiest starting points for most people.
