Which tool should you reach for first?
If you are not sure where to start, this order matches how most people actually work: price the prompt, write it properly, then clean up whatever comes back.
**Token & cost estimator** answers the question that usually has a deadline — is this call worth making on this model. **Prompt template filler** turns a tested structure into a finished prompt. **Text statistics and cleanup** removes the whitespace and duplication that pasting introduces. **JSON extractor** and **Markdown converter** handle the two handoff formats: pulling structure out of a reply, or turning Markdown into something another system can read.
None of the five needs an account, and none of them sends your text anywhere. They are built to be used in the middle of other work rather than as a destination you visit.
Choosing a tool
Where should I start?
The token and cost estimator — it tells you roughly what the prompt will cost before you write it.
Do the tools share data with each other?
No. Each tool is independent, which is exactly why none of them needs to store anything.
Can I use these at work?
Yes. The text never leaves the browser, so there is no third-party disclosure to account for.
Does it cost anything?
The tools themselves are free forever. Paid plans exist for teams who need a shared prompt library and do not affect these tools.
Not sure where to start?
Almost everyone's first question is what this will cost — the token estimator answers it directly.
