Learn Git by walking through your codebase in a 3D voxel world
Renders any Git repository as a walkable voxel world, turning commits, branches, and the staging area into spatial objects you can explore.
A character-led tutorial teaches Git fundamentals progressively, starting from the very basics and building toward everyday workflows.
Try Git operations and see the outcome visualized before running anything against your real project, so mistakes stay harmless.
Inspect, navigate, and edit your code directly from inside the 3D environment without switching tools.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
