AI cron generator — plain English to cron expression
Describe a schedule in plain English and get a correct five-field cron expression, with a confirmation of when it will run. This is a bring-your-own-key AI tool: it works with your Anthropic (Claude) or OpenAI (GPT) API key, which is stored only in this browser and never sent to us to keep. Your text goes to your chosen provider through our server, which never logs or stores your key or your text. It is free — you pay the provider directly for what you use.
How to use it
- Add your Anthropic or OpenAI API key in the key bar (it is saved only in this browser).
- Paste your text and pick any options.
- Press the button — the result comes back from your chosen AI. Copy or Download it.
FAQ
How do I make a cron expression?
Describe the schedule (for example, every weekday at 9:30am), add your key and press Generate cron. The AI returns the expression and confirms in words when it fires.
Is my description kept private?
Your API key lives only in this browser's local storage. Each request sends your text and key to your chosen AI provider through our server, which never logs or stores either. We keep no copy.
Does it handle standard cron?
Yes — it produces standard five-field cron. For special syntaxes, mention the system (for example, Quartz) in your description.
Where do I get an API key?
From your provider: Anthropic (console.anthropic.com) for Claude, or OpenAI (platform.openai.com) for GPT. Paste it into the key bar once and it is remembered on this device until you clear it.
Does it cost anything?
The tool is free. You pay your AI provider directly for the tokens each request uses — usually a fraction of a cent for short text.
Limits
Confirm the plain-English readback matches your intent before scheduling anything critical. Unlike our offline tools, this one calls a cloud AI, so it needs a connection and your own key.
