What we do

Classroom tools should help teachers lead the room, not add another system to manage. We bring groups, seating, timers, schedules, noise monitoring, and more into one flexible whiteboard. Teachers can build the exact classroom view they need and start in seconds.

What began as a simple group generator is now an all-in-one classroom workspace. Every tool is designed to be clear on a projector, quick to control, and easy to use without training.

Sticker features built for whiteboard rewards and signage

A free library of 270+ classroom stickers plus AI generation for custom ones, all with transparent backgrounds ready to drop on any zone of the canvas.

A free library of 270+ stickers

Fifteen categories: rewards, smileys, hands, celebrations, holidays, school supplies, animals, food, weather, nature, space, transport, games, music, and symbols. Pick one and it lands on the canvas instantly, free for everyone.

Search built for teachers

The search matches classroom words, not just sticker names. "Well done" finds the trophy and the medal, "winter" finds the snowman and the snowflake.

Transparent backgrounds

Every sticker floats directly on your whiteboard without a white box behind it, or sits on a tinted sticky-note plate with rounded corners if you prefer.

Drop on any group

A "Group 3 champions" trophy, a science-fair medal, a quiet-corner mascot, all draggable onto whichever group or zone of the board they belong to.

AI sticker maker (Pro)

Describe any sticker ("a happy cartoon trophy with stars") and ChatGPT image generation cuts a custom die-cut PNG in one of four styles: cute cartoon, kawaii, flat vector, or hand doodle.

Shared with the image widget

Every AI generation goes into a shared recent-generations library, so the image widget and sticker widget can pull from the same set without spending more credits.

As easy as 1, 2, stuck!

Three quick steps from the sticker library (or an AI prompt) to a transparent sticker on any group, zone, or name.

Drop the sticker widget

Add the sticker widget to any whiteboard from the toolbar. The library opens right in the settings drawer.

Pick or describe a sticker

Browse categories or search the free library, or switch to the AI tab and type a short prompt (Pro).

Drag it into place

The sticker drops onto the canvas with a transparent background, ready to drag, resize, and place where it belongs.

Got questions? We have answers!

Can't find what you're looking for? We're here to help.

Is the sticker widget free?

Yes. The built-in library of 270+ stickers is completely free, no account needed. Only AI generation is Pro, because image generation has real cost on our end. Pro includes 30 monthly AI credits shared across every AI feature, including stickers and AI images.

What stickers are in the free library?

270+ stickers across 15 categories: rewards (trophies, medals, thumbs up), smileys, hands, celebrations, holidays, school supplies, animals, food, weather and seasons, nature, space, transport, games, music, and symbols like checkmarks, math signs, and light bulbs. We keep adding more.

How does the transparent background work?

The AI is asked to render the sticker on a flat pure-white plate. Once the image comes back, the browser scans from the edges of the canvas inward and replaces the background white with transparency, leaving inner whites (eyes, highlights, the sticker outline) intact.

What model are you using?

gpt-image-2, the latest "ChatGPT Images 2.0" image generation model from OpenAI. It produces classroom-quality artwork on a tight prompt-to-output cycle.

Can I reuse a sticker on another whiteboard?

Yes. Every generation is saved to a shared recent-generations library on your device. The image widget and the sticker widget both pull from that library, so a previous sticker can be dropped on a new board without spending another credit.

How many stickers does a credit make?

One credit per generation. Reusing a saved sticker from the recent-generations strip does not spend a credit.

Why do my stickers sometimes have a faint white edge?

The background cut is alpha-soft right at the edge to avoid a hard halo. If you ever see a thin ring, regenerate with a slightly more specific prompt ("with a thick white sticker border") or pick the kawaii preset, which produces the cleanest outline.

Can I edit a generated sticker?

You can re-prompt to generate a new variation, or remove it and start over. We do not offer in-painting / pixel-level edits inside the widget.

Do you share student details with the AI?

No. The prompt and the chosen style preset are the only data sent. Class names, student names, and personal information never leave your browser.

What if my prompt gets blocked?

gpt-image-2 has its own content safety policy. If your prompt is blocked, you will see a friendly toast asking you to rephrase. No credit is spent on a blocked generation.

Why should I upgrade to Pro?

The complete library of 270+ classroom stickers is free. Pro adds the AI Sticker Maker so you can describe a custom reward or visual and generate it with one of your 30 monthly AI credits. Generated stickers can be reused without another credit, and your boards sync across devices.
