Hire tested AI trainers and data labelers for RLHF, evaluation, and annotation
Post a project and receive a shortlist drawn from a network of more than 711,000 people across 240+ countries, available in 120+ languages.
Applicants pass automated interviews and domain skill assessments, and managed programs add live proctored testing, so candidates are matched on demonstrated ability rather than self-reported skills.
Hire managers can add experts straight into Label Studio, CVAT, Labelbox, Argilla, or another tool they already run, avoiding data migration.
Beyond standard labeling, the network covers RLHF preference ranking, DPO pair generation, reasoning verification, adversarial red teaming, and human benchmarking.
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.
