Questions & Answers

As answered by people managing Diff Checker and textToolkit.dev.

Which are the primary technologies used for building your product?

textToolkit.dev's answer:

Astro (for a fast, mostly-static site architecture) and Tailwind CSS for styling, with vanilla JavaScript powering the client-side text processing in each tool. No backend or database is required since all processing happens in the browser.

What makes your product unique?

textToolkit.dev's answer:

textToolkit runs entirely in the browser — no text is ever uploaded, stored, or sent to a server. Every conversion, cleanup, and analysis happens client-side, making it a genuinely private option for working with sensitive content. It also covers a wide range of tools (case conversion, text cleanup, analysis, and fun utilities) in one consistent, fast interface, rather than requiring separate bookmarks for each task.

What's the story behind your product?

textToolkit.dev's answer:

textToolkit started as a simple case converter built to solve a common, everyday annoyance — reformatting text between different capitalization styles. It quickly grew into a broader toolkit as it became clear the same problem existed across dozens of small text tasks: removing extra spaces, cleaning up pasted HTML, counting characters for a tweet, generating a URL slug. The goal became building one fast, ad-light, privacy-respecting home for all of these small but frequent tasks.

Why should a person choose your product over its competitors?

textToolkit.dev's answer:

Most free text-tool sites are cluttered with ads, slow, or send your text to a server to process it. textToolkit is fast, clean, works well on mobile, supports dark mode, and processes everything locally in the browser — so there's no privacy tradeoff and no waiting on a server round-trip. It's also actively growing, with new tools added regularly based on real user needs.

How would you describe the primary audience of your product?

textToolkit.dev's answer:

Writers and bloggers who need to fix formatting or capitalization; developers who need to convert variable naming conventions (camelCase, snake_case) or clean up data; students working on essays and citations; and social media/content marketers who need character counts, slugs, or quick text formatting for platforms like Instagram and Twitter/X.

Who are some of the biggest customers of your product?

textToolkit.dev's answer:

textToolkit is newly launched and used by individual writers, students, and developers rather than enterprise customers at this stage. As a free, sign-up-free tool, usage is anonymous and not tracked by company or account, so no user data is available to name specific customers.

    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you... Source: over 3 years ago
