Korean spacing corrector

Paste Korean text with broken spacing and press Correct — an on-device AI model restores the spaces. Text never leaves your browser.

How to use

• Paste Korean text and press Correct spacing. The first run downloads the model, so it may take a few seconds.
• The corrected text appears below, ready to copy.
• Works on text with no spaces at all and on text with awkward spacing.

Under the hood

URLs, English phrases, and list markers are left untouched; existing spaces are treated as reliable boundaries and only missing ones are predicted. The model is downloaded and runs on your device, so nothing is sent to a server. For full paragraph cleanup, use the Text Tidy formatter.
