CronAI
Free web tool that turns a plain-English schedule into a five-field cron expression for crontab, CI and cloud schedulers.
What is CronAI?
CronAI is a small web page that writes cron expressions for you. You type when a job should run, such as every weekday at 9am or the first day of every month at midnight, press Generate, and the tool returns the matching five-field cron string. It saves the trip to a syntax reference when you cannot remember whether the day-of-week field comes before or after the month. The page shows sample prompts you can click, including every 5 minutes, every Sunday at 3:30pm and twice a day at 6am and 6pm. The output uses standard cron syntax, so it can be pasted into Vercel Cron, Kubernetes CronJobs, AWS CloudWatch, GitHub Actions, Linux crontab and other cron-compatible systems. It is aimed at developers and operations people who set up scheduled jobs only now and then. No sign-up, plans or paid tier are shown, and the site calls itself a free cron expression generator.
Use cases
- Generate a cron expression from text
- Schedule a GitHub Actions workflow
