AI image generator
Tell Sparky what students need to see, like a labeled water cycle or a scene from a novel. Sparky draws the picture for your slide, worksheet or wall, then redraws it until it's right.
Used by 250,000+ teachers, and built to FERPA, COPPA and GDPR standards.
How the image generator works
Say what students should see
Type what the picture should show and who it's for, such as "water cycle for 4th grade". Say where students will see it too: wide pictures fit slides, and tall ones fit posters.
Check the picture
Sparky draws it in a panel beside the chat in under a minute and tells you what to check. Ask for changes in plain words, like "make the labels bigger".
Download it
Press Download to save the picture for your slides, worksheet or class newsletter. You can also ask Sparky to put it on a worksheet.
What Sparky can draw
Labeled diagrams
Cycles, life stages, the parts of a cell or a volcano, with clear labels and arrows that show the order.
Scenes and characters
A scene from a novel, a street in ancient Rome, or a character for a class story, in cartoon, realistic or picture book style.
Fill-in versions
The same picture with blank labels, and a word bank in the chat. The labeled picture becomes your answer key.
Your own photo, changed
Upload a photo or another picture and ask Sparky to add labels, change colors or take out clutter.
Ways teachers use it

A picture that opens the lesson or explains one step, drawn wide to fill the slide.

Frequently asked questions
Is the image generator free?
Yes, it's free for teachers.
Are the images safe to show students?
Sparky is set up to make classroom-safe pictures for teaching, and you see each picture before your students do. Check labels and small details before you share one, because an AI picture can get them wrong. Sparky notes the details worth checking.
How do I get the picture into my slides or worksheet?
Press Download in the image panel to save the picture, then add it to Google Slides, PowerPoint, a Google Doc or Word. To build a worksheet around it, ask Sparky to put the picture in a document, which you can print or export to Google Docs or Word.
Can Sparky change a picture I already have?
Yes. Upload a photo or a diagram in the chat and say what to change, such as "label the parts of this flower" or "make the background plain white". Sparky draws a new version and your upload stays as it was.
Can it make graphs and charts?
Ask for a graph when the numbers have to be exact, like a line on a coordinate plane or a bar chart of class data. Sparky plots it with code so the values are right. The image generator is for pictures and diagrams that explain an idea.
Can the images carry a watermark?
Yes. Your school's owner in Flint can turn on a small Flint mark in the corner of every image Sparky makes (how to turn it on). It's off unless your school turns it on.
Which AI model draws the pictures?
gpt-image-2.5-flare, an OpenAI image model. Sparky turns your request into a detailed description for the model, so you can ask in plain words.
