Help us put instant, private, offline translation in everyone's pocket — no signal required.
Understood anywhere, even offline — PlainSpeak gives instant, private translation for the exact moments a language barrier is most dangerous to have, and it works entirely on-device.
PlainSpeak is an offline-first speech, text, and camera translation app for iOS and Android, built and maintained by EqualInformation, LLC. It translates conversation, typed text, signs, menus, and documents entirely on-device — two-person conversation mode, live camera overlay, offline language packs you download before you go, and a currency & unit converter for everyday travel use.
Every feature is designed with privacy at its core — PlainSpeak is 100% on-device with no account required, no servers, no cloud sync, and no tracking, and the whole app works fully offline once a language pack is downloaded. Emergency, medical alert, legal-rights, and every accessibility feature are free, permanently, with no exceptions. PlainSpeak is live now on Google Play, with the App Store version currently in review. Your support helps us keep the core free for everyone and keep building out the rest.
Every human hits a language barrier at some point, and offline is a genuine superpower, not a limitation: refugees crossing borders, disaster zones with no signal, low-income countries with expensive data, and rural areas with no coverage are exactly where cloud-dependent translation apps fail.
Trust matters most in the moments PlainSpeak is built for — immigration interviews, medical visits, legal proceedings — where an app has to do more than promise privacy on a page. On-device processing means what you say never leaves your phone.
PlainSpeak flags translations it isn't confident about rather than presenting them as certain, and it is a communication aid, not a replacement for a professional interpreter in high-stakes situations.
Information shared is power shared. Real-time translation should reach everyone, without an account, a connection, or money — that is why PlainSpeak's emergency, medical, legal-rights, and accessibility features are free forever, and why it is part of the EqualInformation portfolio.
Disclaimer: PlainSpeak provides on-device translation for informational and communication purposes. It is not a substitute for a professional human interpreter in high-stakes medical, legal, or emergency situations. If you are experiencing an emergency, contact your local emergency services immediately.
