FAQ
Are these tools really free?
Yes — every tool listed here is free, with no account and no limit on use. Pro is optional: it puts your own brand on client exports instead of the vishvaddi.com footer and adds cross-device sync on the tools that support it.
Is anything I type uploaded?
No — every tool runs entirely in your browser. A few fetch public reference data (like currency or commodity prices) but never send your inputs anywhere.
Do I need to sign up?
No — no account, no sign-up. Open a tool and start using it straight away.
How do I find the right tool?
