About Text Toolkit
Fast, private, ad-supported text utilities — all in one place.
What it is
Text Toolkit is a single-page workbench for writers, students, developers, and content creators who work with text every day. Instead of bouncing between half a dozen different single-purpose sites, you can paste your text once and switch between the tools you need without losing your work.
The shared text buffer
Most online text tools are isolated: you paste into a word counter, then re-paste into a readability checker, then re-paste into a case converter. Text Toolkit solves that with a shared text buffer. When you switch tools, your text comes with you. This is the feature that took the longest to get right and is the one we hear the most positive feedback about.
Privacy by design
Every tool runs entirely in your browser. The text you paste is never sent to a server — not for analysis, not for storage, not for “processing” of any kind. It is kept locally in your browser’s storage so it persists between sessions, and you can clear it at any time. The full story is in our Privacy Policy.
The tools
- Word Counter — Count words, characters, sentences, and more.
- Case Converter — Transform text between different cases.
- Lorem Ipsum — Generate placeholder text.
- Markdown — Preview and edit Markdown with live rendering.
- Readability — Score your writing's readability.
How it’s built
Text Toolkitis built with Next.js, TypeScript, and Tailwind CSS, and hosted on Vercel’s global edge network. The initial JavaScript bundle is kept small so the site is usable on slow connections and older devices. Heavier features (markdown rendering, large reference word lists for readability scoring) are code-split and loaded on demand only when you visit the tool that needs them.
How it’s funded
The site is free and supported by advertising via Google AdSense. Ads are placed around the tools, never inside the text input or output area, and we do not run interstitials, auto-play video, or pop-ups. If you have a question about a specific ad, please get in touch.
