I built a free clipboard transformer for Windows with Tauri + React

I kept running into the same friction every day — paste some text, then spend 30 seconds manually cleaning it up. Strip the AI opener, fix the spacing, format the JSON, decode the URL. Every. Single. Time.

So I built PasteLab.

What it does

PasteLab sits in your taskbar and the moment you open it, it already knows what you copied. It classifies content into 12 types automatically:

Plain text, AI-generated prose, source code
URLs, JSON, hex/RGB/HSL colors
Email addresses, CSV, Markdown, secrets, numbers

Then it surfaces exactly the right one-click transforms for that content type. No digging through menus.

The AI humanizer

My favorite feature. It strips AI openers ("Certainly!", "In today's fast-paced world..."), filler phrases, and buzzwords — then adds natural contractions and real sentence rhythm. Five intensity levels, and a live word-level diff so you see exactly what changed before applying it.
