Real-time image generation canvas that aggregates many underlying models under one subscription.
What it is good at
Real-time mode is the standout teaching feature — a student sketches roughly and watches the render update live, making the relationship between input and output visible in a way prompt-and-wait tools cannot. Commercial rights are included even on the free tier, which is unusually clean.
Use it for
Running a live ideation exercise where students sketch thumbnails and see real-time renders to explore composition. Training a small LoRA on a student's own drawings so the model generates in their personal style — a strong authorship discussion. Upscaling student illustration for large-format print.
Where it falls short
The 100 units per day free tier disappears in a handful of high-quality generations and blocks video entirely. Because it wraps third-party models, provenance depends on which model ran and Krea does not surface per-model training disclosure, so a student cannot answer 'what was this trained on' — which breaks attribution assignments. Real-time mode encourages volume over developed work unless you structure against it.

Art: Real-time rendering makes the input-to-output relationship visible, which is hard to teach otherwise.
