How to Use Krea Realtime to Generate Images as You Type
Krea Realtime is a browser-based image generator that updates the picture as you type the prompt instead of waiting for a finished render. There is no Generate button you press and pray over — the canvas responds live.
That live loop is the whole point. It changes how you write prompts, because you stop writing one perfect sentence and start steering a picture in real time.
What is Krea Realtime?
It is a real-time diffusion feature from Krea, the studio behind Krea AI. The model keeps a low-resolution draft on screen and refines it as your input changes, so you get feedback in well under a second on a decent GPU or a stable connection. You type “a red fox in snow” and a blurry fox appears; you keep typing “at dusk, oil painting” and it shifts live.
Runs in the browser. No install. A free Krea account gives you a limited number of daily generations, and paid plans raise that ceiling and unlock higher output resolution.
How do you drive it step by step?
- Sign in to Krea and open the Realtime canvas.
- Type a short starting prompt — five to eight words is plenty.
- Watch the draft land, then add modifiers one at a time instead of rewriting the whole line.
- Switch to the sketch or draw mode to place shapes and let the model dress them.
- Use the image-to-image mode to feed a reference and dial the strength slider.
- When you are happy, raise resolution and export.
The habit that matters: add, do not rewrite. Every full rewrite restarts the draft, and you lose the composition you were building.
What does the strength slider actually do?
In image-to-image mode, strength controls how far the output drifts from your reference. At 0.2 it barely changes the input. At 0.8 it keeps the rough shape but repaints almost everything. Most useful work happens between 0.4 and 0.65, where structure survives and style changes.
What are the practical limits?
The live preview is deliberately low resolution. Fine text, small faces, and exact logos will not be sharp until the final pass. The real-time speed also depends on the model you pick — the fastest model looks rough, the heavier ones look better but lag behind your typing.
Free daily generations run out quickly if you export a lot. Budget them for the images you will actually use.
Who is it for?
It suits illustrators exploring composition, marketers testing thumbnail directions fast, and anyone who thinks visually and hates writing long prompts blind. It is a poor fit for pixel-exact product shots or anything needing consistent characters across many images, where a batch workflow with seeds beats a live canvas.
Key Takeaways
- Krea Realtime redraws the image while you type, with sub-second feedback.
- Add modifiers one at a time rather than rewriting the prompt.
- Image-to-image strength of 0.4-0.65 keeps structure while changing style.
- Live preview is low resolution; export for final quality.
- Great for exploration and thumbnails, weak for exact or consistent output.
