Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
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.
