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.
Free browser-based AI code translation and Python type conversion
Translate source code between Python and other programming languages, with prebuilt entry points for common pairs like Python to Node.js, C++ to Python, C to Python, Scratch to Python, and HTML to Python.
Convert values between Python data types such as strings, integers, floats, lists, and dictionaries without writing the boilerplate yourself.
Run short Python snippets directly in the browser to check syntax and behaviour before pasting the code into your own project.
Short reference guides on Python fundamentals, including dictionaries and for loops, that sit alongside the converters for quick lookup.
