AI-assisted data annotation companion for faster, smarter labeling
The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
The developer declares that user data is not sold or shared and is not used for unrelated purposes.
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.
