Turn any code snippet into an interactive flowchart you can actually read
Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.
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.
