I Built a Browser Tool That Detects What You Paste

#showdev #webdev #productivity #javascript

I kept switching between tiny web tools just to handle everyday developer tasks:

  • Formatting JSON
  • Decoding Base64
  • Cleaning URLs
  • Converting Unix timestamps
  • Removing duplicate lines
  • Transforming text

So I built QuickTiny.

The main feature is Smart Actions: paste almost anything, and QuickTiny tries to recognize the content and suggest the right tool automatically.

For example:

  • Paste JSON → format and validate it
  • Paste Base64 → decode it
  • Paste a Unix timestamp → convert it
  • Paste URL-encoded text → decode it
  • Paste a list → clean, sort, or remove duplicates

Everything runs locally in the browser. There is no signup, and the pasted content is not uploaded.

QuickTiny currently includes 13 small browser tools. I’m trying to keep the interface fast and focused instead of turning it into a crowded toolbox.

Try it: https://quicktinyv2.vercel.app

Watch the short Smart Actions demo: https://quicktinyv2.vercel.app/quicktiny-smart-actions-demo.mp4

I’d appreciate honest feedback—especially examples that Smart Actions detects incorrectly or tools you repeatedly need during development.

Try Smart Actions with any of these examples:

{"name":"QuickTiny","private":true}
Enter fullscreen mode Exit fullscreen mode 
SGVsbG8gREVWIQ==
Enter fullscreen mode Exit fullscreen mode 
1767225600
Enter fullscreen mode Exit fullscreen mode

If QuickTiny routes an example to the wrong tool, please paste a non-sensitive version here. Those edge cases are the most useful feedback for improving detection.
