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 above to get started.
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.
Frequently asked questions
Are these tools really free?
Yes. Every tool in the Tool Lab is free to use, with no trial, no credit card, and no usage limit. There is no paid tier holding back the useful part.
Is anything I type uploaded or saved?
No. The tools run entirely in your browser, so what you type never reaches our server and is never stored or logged. Closing the tab is enough to clear it. If a tool ever needs to send your input somewhere, it says so on its own page before you start.
Do I need an account to use them?
No. There is no sign-up, no login, and no email required to see your result. You can use any tool and leave without giving us anything.
How do the tools decide their answers?
Each one applies a fixed set of rules to what you enter, rather than asking a live AI model. That is why the same input always gives the same result. Every tool also shows what it checked and why you got the result you did, so you can judge whether you agree with it.
