What it does

CronAI is a small single-purpose tool. You type when something should run, for example every weekday at 9am, and it returns the matching cron expression. The site says it produces five-field cron syntax that works with cron-compatible systems such as Linux crontab, GitHub Actions, AWS CloudWatch, Kubernetes CronJobs and Vercel Cron. Example prompts on the page include every 5 minutes, the first day of every month at midnight, and twice a day at 6am and 6pm.

Capabilities

  • Plain-English schedule in, cron expression out
  • Standard five-field cron syntax
  • Example prompts to start from
  • Described on the site as free

When to use it

  • You cannot remember the cron syntax for a particular schedule
  • You are writing schedules for crontab, GitHub Actions, CloudWatch, Kubernetes CronJobs or Vercel Cron
