ABOUT THIS NOTEBOOK
Small tools.
A little clarity.
Fenglong is a personal collection of practical notes and simple tools for everyday writing and technical work.
Your text stays with you
The word counter, time converter, and JSON formatter run locally in your browser. They do not upload the text or values you enter. The site uses no advertising, third-party analytics, cookies, or browser storage.
As with any website, delivering pages involves network information such as an IP address. Limited infrastructure and security logs may be kept to maintain the service; the tools do not send their input to the server.
Use with care
These are small utilities, not a substitute for checking important data. Reading times are estimates. The time converter uses your browser's time zone data. Keep an original copy of a document before making changes.
