Chat and snap your way to easier calorie tracking
Describe meals and workouts in natural language and let the AI convert them into calories and macros without a searchable food database.
Snap a picture of your plate and the app estimates portion size, calories, and macros — useful when dining out or facing complex recipes.
Set protein, carbohydrate, and fat targets and watch your intake update automatically as you log meals.
Log activity in the same chat and see calories burned alongside calories consumed for a full energy-balance view.
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.
