Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.

Pressure-sensitive brushes with hundreds of styles, layers and groups, layer masks, adjustment layers, selections, transform tools and re-editable text.
Tap-fill hundreds of outlined pictures, then press "Grade me!" so the app assesses coverage and line discipline and celebrates with sparkles, stars and medals.
Friendly step-by-step shape tutorials that award a star for every attempt, building real drawing skill without pressure.
Apply Cartoon, Oil paint, Neon, Glitch and other looks to an imported photo, and change them later without the original image ever being altered.
