I Built a Free Online Text Toolbox: No Registration Needed, 20+ Tools Ready to Use
During the National Day holiday, I spent a few days building a free online text tool called TxtDock: https://txtdock.com/. It was created both for personal use and to help others. This text tool requires no registration; most tools process data locally in your browser to ensure privacy and security, while a few tools utilize AI assistance (clearly marked).

Feature Highlights
Pangu Spacing
Does this name sound impressive? The function simply adds a space on both sides of English characters when mixing Chinese and English input, making it look more comfortable, especially for those with perfectionist tendencies. See the effect below:

Token Counter
The Token Counter estimates how many AI tokens a piece of text roughly equals, helping you stay informed when calling AI APIs.

Docker Command to Compose
Input a Docker command, and it will automatically convert it into a compose.yaml file with download support. It also supports adding DNS settings, memory limits, etc., making it ideal for DevOps personnel. The backend uses AI for intelligent conversion.

Log Error Analysis
Copy an error log and paste it here; AI will automatically analyze the cause and provide solutions and ideas. This is very suitable for developers or operations staff.
