About KeySwap
KeySwap is a free, instant keyboard layout converter that helps you fix mistyped text when you accidentally type with the wrong keyboard language enabled.
Our Story
KeySwap was born out of a daily frustration shared by millions of multilingual users. As a developer who regularly switches between English and Thai keyboards, I found myself frequently typing entire paragraphs in the wrong language without noticing. The usual fix? Delete everything and retype from scratch.
That frustration led to a simple idea: what if a tool could instantly map every wrong character back to the correct one? After researching keyboard layout mappings and building a conversion algorithm that handles bidirectional conversion with Shift-state awareness, KeySwap was launched in mid-2025 to help anyone who faces the same problem — whether they're typing in Thai, Russian, French, German, Japanese, or Korean.
Today, KeySwap serves users from around the world who need a quick, private, and reliable way to recover text typed with the wrong keyboard layout. The tool processes everything locally in your browser, ensuring your text never leaves your device.
The Problem We Solve
Have you ever started typing an email, message, or document only to realize you were typing with the wrong keyboard layout? Instead of "Hello, how are you?" you end up with something like "ำนรำแ ้แง ฟสำ ้แก?" (if your Thai keyboard was active) or "Ру|ддщб рщц фку нщг?" (with Russian layout).
This frustrating experience is incredibly common for multilingual users, professionals working with international teams, and anyone who regularly switches between keyboard languages. The traditional solution? Delete everything and retype. KeySwap offers a better way.
How KeySwap Works
KeySwap uses intelligent character mapping to convert your mistyped text back to what you actually intended to type. When you type "สวัสดี" with Thai layout but meant to type English, or vice versa, our algorithm maps each character to its corresponding position on the other keyboard layout.
Technical Highlights:
- 100% Client-Side: All conversion happens in your browser. Your text never leaves your device.
- Instant Results: See converted text in real-time as you type or paste.
- Bidirectional: Automatically detects and converts in both directions.
- Shift-State Aware: Correctly handles capitalized letters and special characters on the number row.
- No Installation: Works directly in your web browser, no downloads needed.
