Craiyon is the free image generator I use with students because there is no account required and it generates nine options at once

Practical post for educators and anyone who needs a genuinely free image generation option with no friction.

I teach at secondary school level and I use AI image generation for classroom materials, worksheets, presentation visuals and project examples. The budget for tools is essentially zero and the ability to have students use something without account creation or data privacy concerns is a real constraint.

Craiyon is free, browser-based and does not require an account to use. You type a prompt, it generates nine variations, you pick the one that works. For classroom use cases that simplicity is the feature.

The nine-image grid per generation is more useful than it sounds. Rather than getting one result and deciding whether to regenerate, you have nine simultaneous variations to compare. For a specific use case like generating an illustration of a historical scene for a worksheet, having nine options means one of them is usually close enough to use without multiple regeneration rounds.

The Style Presets, Art, Photo, Drawing, help steer the output in the right direction before you start refining the prompt. For student work the Drawing style produces cleaner results for educational contexts than the more realistic modes.

The Expert Mode negative prompts let you specify what you do not want. "No text in image," "no blur," "no modern buildings" for a historical setting. That control improves results significantly once you learn to use it.

Prompt Enhancement suggests more detailed versions of basic prompts which is useful for students learning how to communicate with AI tools.
