Frequently Asked Questions
Are these tools really free?
Yes — every tool here is free with no sign-up, no ads, and no usage limits. They exist because we build the Synapse AI keyboard for Android and want people to find it.
Is my text sent to a server?
No. Every tool runs entirely in your browser using JavaScript. Nothing you type or paste is uploaded, logged, or stored anywhere but your own device.
Do the tools save my work?
Tools that benefit from it save drafts, scores, and settings in your browser's local storage — on your device only. Clearing your browser data clears them, and nothing syncs between devices.
Do they work on a phone?
Yes. All the tools are mobile-first and work in any modern mobile browser, including copy-to-clipboard and share-to-WhatsApp.
