Eight tools for everyday jobs

This set covers writers, developers, students, designers, marketers, and office work. Each tool opens on its own page, with notes on how to use it well.

  • Password Generator

    Create strong passwords with control over length, numbers, symbols, and letter case.

  • QR Code Generator

    Turn links or short text into a QR code for print, sharing, labels, and quick access.

  • Markdown Previewer

    Write Markdown on one side and see the formatted result on the other.

  • Regex Tester

    Test a pattern against sample text and see what matches before using it in code.

  • Text Diff Checker

    Compare two blocks of text and spot the changes without reading line by line.

  • Word and Character Counter

    Count words, characters, sentences, and spaces for posts, forms, and drafts.

  • Case Converter

    Switch text between uppercase, lowercase, title case, sentence case, and slug style.

  • Color Converter and Picker

    Pick colors and convert between HEX, RGB, and HSL for design and front-end work.

Small tools, built with care

We built this site for the little tasks that interrupt real work. The kind that shouldn’t need an account, a tutorial, or a download. Each tool is simple on purpose. You paste, type, pick, or upload where needed, then copy the result and keep going.

We also care about privacy. Text tools are designed to work in your browser whenever possible. That means your drafts, patterns, and generated passwords don’t need to be sent away just to do basic work.

  • Private by design

    Every tool runs in your browser. What you type or paste isn’t sent to us, so drafts, patterns, and passwords stay on your device.

  • Fast and focused

    No sign-up, no install, no tutorial. Open a tool, get the answer, copy it, and get back to work.

  • Explained in plain language

    Each tool page says what the tool does, how to use it, where it can mislead you, and answers the questions people actually ask.

Who uses ToolKit Slate

  • Writers and marketers

    Check length limits with the Word and Character Counter, fix shouting headlines with the Case Converter, and review edits with the Text Diff Checker.

  • Everyone else

    Make a strong password, or turn a link into a QR code for a flyer, a menu, or a classroom handout.

A note on ads. ToolKit Slate is free to use and supported by ads. Ads help pay for hosting and upkeep, but they shouldn’t get in the way of the tool you came for.
