Frequently asked questions
Everything people ask before they start using the toolkit.
The basics
Is the toolkit really free?
Yes. Every tool runs in your browser, so there is no server cost for us to recover and no reason to meter usage.
Do I need an account?
No. Nothing on this site requires sign-in, and no tool stores anything on a server.
Where is my text sent?
Nowhere. The tools have no backend — the text you paste is processed in the page and discarded when you close the tab.
Privacy and security
Can you read what I paste?
No. There is no request that carries your text. Nothing to log, nothing to retain.
Can I use this with client data?
That is the point of running locally. Your obligations to your client are unchanged, but this site adds no third party to the chain.
Do you use cookies?
Only what is needed for the theme and language you pick. See the cookie policy for the exact list.
Accuracy and limits
How accurate is the token estimate?
It is a heuristic — roughly one token per CJK character and one token per four characters elsewhere. Treat it as a sizing guide, not an invoice.
Which models are priced?
GPT-4o, GPT-4o mini, Claude Sonnet and Gemini Flash. Prices are reviewed whenever a provider changes them.
Can the JSON extractor repair broken JSON?
No. It extracts the first balanced value; it does not fix syntax errors.
Technical
Which browsers are supported?
Any current version of Chrome, Edge, Firefox or Safari.
Does it work offline?
Once the page has loaded, yes — nothing is fetched while you work.
What if a tool is removed?
Your text was never here to lose. The page simply stops existing.
Can I embed a tool on my own site?
Talk to us — for teams on a paid plan we can discuss it.
Still stuck?
Send us the details and we will work it out.
