↳ Text tools
Text tools that work as fast as you type.
Count words, fix capitalization, compare two versions, clean up messy lines, and turn text into reading time. Every tool runs instantly in your browser, so you get the answer the moment you paste.
Text tools are lightweight utilities that count, transform, compare, or clean written text without a desktop app. ToolBook brings the whole set into one tab: measure length, reformat case, find the differences between drafts, strip duplicate or blank lines, and estimate how long a piece takes to read.
They share one idea. You paste text and the result updates live, with no upload step and no waiting. The text stays inside your browser, so drafts, code snippets, and private notes never leave your device.
Writers reach for the word counter and the reading time estimate to hit length targets. Developers lean on diff, sort, and find and replace. Students and editors use case conversion and duplicate removal to tidy messy source text. Most jobs take one paste and one glance.

Frequently asked questions
What are text tools?
Text tools are small utilities that count, transform, compare, or clean written text in your browser. Common ones include a word counter, a reading time estimator, a case converter, a text diff checker, and tools to sort lines or remove duplicates. ToolBook collects them in one place so you do not need a separate app for each job.
Are these text tools free to use?
Yes. Every text tool on ToolBook is free and runs entirely in your browser. There is no upload step, and the text you paste stays on your device.
Is the text I paste private?
Yes. These tools process text on the client side, inside your browser, so what you paste never travels to a server. That makes them safe for drafts, code snippets, and confidential notes.
Which tool counts words and characters?
The word counter gives a live tally of words, characters, sentences, and paragraphs as you type. To turn that word count into minutes, the reading time calculator estimates how long the same text takes to read or to read aloud.
How do I compare two pieces of text?
Use the text diff tool. Paste an original and a revised version, and it highlights every added, removed, and changed section side by side. It is the fastest way to spot what changed between two drafts.
Can I use these tools for content writing and SEO?
Yes. Writers use the word counter and reading time estimate to hit length targets, the case converter to format headings, and the duplicate and whitespace removers to clean up pasted copy. For keyword analysis, pair them with the keyword density checker.
