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.
Turn plain-English schedules into ready-to-paste cron expressions
Type a schedule in plain English — 'every weekday at 2 PM', 'every 30 minutes', '15th of each month at 3 PM' — and receive a standard five-field cron expression to copy.
The site states all conversion happens in your browser with no scheduling data stored or transmitted to external servers, keeping infrastructure details private.
Output targets standard Unix cron format, working across Linux crontab, Vixie cron, macOS cron, AWS EventBridge, Kubernetes CronJobs and CI/CD pipeline definitions.
Documents each cron field, explains special characters like *, /, L, W and #, and shows conversions for time-based, day-based and monthly schedules.
