About ToolNest

ToolNest was built on a simple idea: everyday online tools should be free, fast, and private. No accounts, no paywalls, no uploading your text to a server — every tool on this site runs entirely in your browser using JavaScript.

We started with the utilities we found ourselves needing daily: counting words, converting text case, validating JSON, generating passwords. Each tool is designed to do one job perfectly, load in under a second, and work on any device.
