Free Tools

Free, practical tools that help you use AI more safely and get better results. No sign-up, no downloads, and nothing you type is ever saved. Every tool runs entirely in your browser.

The TwistyApps Tool Lab is a growing collection of small, focused utilities. Check a document’s privacy risk before you paste it into AI, score a prompt, build an honest job-search prompt, work out what to verify in an AI answer, plan how to learn AI, or understand what an app’s permissions really mean. Pick one below to get started.

Why use these tools

Free and no account. Every tool is completely free, with no sign-up and no email required to get your result.

Private by design. Everything runs in your browser, so what you type is never uploaded, stored, or logged.

Explained results. Each tool shows what it checked, why you got the result, what to do next, and its honest limitations.

Built to help. No fluff and no hard sell, just a clear answer to a real question.

What each tool helps with

How the tools work

These are not chatbots. Each tool uses clear, transparent rules and scoring rather than a live AI model, which is what keeps them fast, private, and consistent. A few of them, like the prompt checker and the job-search builder, are designed to help you use AI tools such as ChatGPT, Claude, and Gemini more effectively. We add new tools regularly.
