Text tools
Small tools for working with text: change letter case, remove duplicate lines, sort lines, find and replace, make URL slugs, and a set made for the Thai language (fix text typed on the wrong keyboard layout, numbers as Thai words and baht, Buddhist and Gregorian years, Thai digits). Everything runs in your browser and the text you paste is not sent anywhere.

What you paste stays on your device
Every tool on this page runs entirely in your browser. The text, lists, numbers and files you paste or open are not sent to freesabai's servers or anyone else's, and are not kept in the browser: close the page and they are gone. The site only counts how many times a page was opened and how many times someone copied or saved a result, without what was pasted or the result, and you can switch the counting off in the footer (see the privacy policy).
