Text tools that keep your writing private
Drafts, contracts, student essays and customer lists are exactly the kind of text you should not paste into a random website. SB Tools text utilities process everything with JavaScript in the page, so your text stays on your device and the result appears instantly as you type.
Counts follow clear, documented rules: words are split on whitespace, reading time uses 238 words per minute (the average for silent reading of non-fiction reported by Brysbaert, 2019), and the readability checker uses the standard Flesch formulas.
Frequently asked questions
Is there a length limit?
There is no fixed limit. Most tools handle hundreds of thousands of words; very large inputs are limited only by your device’s memory.
How do I remove duplicates from a list?
Paste the list into Remove Duplicate Lines. You can ignore case and surrounding spaces, and it keeps the first occurrence in the original order.
Is my text stored anywhere?
No. Text is never uploaded or saved by SB Tools. Closing the tab clears it.
