AI Prompt Debugger & Token Counter
Compose a prompt, fill its variables, and compare rough model token estimates before you use your own approved API workflow.
Local preview: this page does not call an AI model or send prompt text anywhere.
Build your prompt
Use {{variable_name}} tags. Names may contain letters, numbers and underscores; malformed tags stay as typed. Up to 20 unique variables get fill-in fields.
Template variables
Add a tag such as {{customer_name}} to create a fill-in field.
Choosing a template replaces only the user template. Existing matching variable values are kept.
Prompt text stays in this page and is not transmitted to Cloudek Hosting servers. Copy JSON places it on your device clipboard only when you click Copy JSON. Download config saves a JSON file on your device only when you click Download config. This tool does not save prompt text in browser storage. Estimates are approximate and should not be used as billing quotes.
