What If Your Clipboard Knew What It Contained? — Building a Chrome Extension for Auto-Detection

"Is This JSON? Base64? URL Encoded?" Someone drops an API response in Slack. I copy it. Open a JSON formatter in the browser. Paste. Formatted. Done. Five minutes later, a Base64 string shows up in another channel. I open a Base64 decoder — wait, this isn't Base64. There's %3D in it. It's URL encoded. I switch to a URL decoder. I do this about 10 times a day. The moment I copy the data, its format is already determined. But I'm the one figuring out what it is, and I'm the one picking the right tool. This "mental routing" is quietly exhausting. "What if the clipboard content was auto-detected, matched to the right tool, and opened — all automatically?" So I built it. Chrome extension PureMark Detect is available now. PureMark Detect — Chrome Web Store PureMark — JSON Formatter, Base64, URL Encoder, Diff Checker, and Timestamp Converter — all in the browser, zero sign-up.
