Frequently asked questions
Everything you need to know about ToolRaven.
Is ToolRaven really free?
Yes — 100% free, forever. There are no hidden paywalls, premium tiers, or usage limits. Every tool on ToolRaven is free to use as many times as you like.
Does ToolRaven store or collect my data?
No. Everything runs entirely in your browser. Your files, text, and inputs never leave your device. We have no servers processing your data and no analytics tracking what you type.
Do the tools work without an internet connection?
Most tools work offline once the page has loaded since all processing is client-side. A few tools that fetch external data (like API Status Aggregator) do require internet access.
Do I need to create an account?
Never. There is no signup, no login, and no email required. Just open a tool and start using it immediately.

How is ToolRaven different from other online tools?
