Real-time message translation: chat across Czech and English

Why translate in-app

About half the Czech rental market communicates in Czech only. If you only speak English, that's a huge slice of listings you'd otherwise miss. Forcing yourself or the host into a second language adds friction and misunderstandings. In-chat translation removes the language barrier entirely; both sides talk in whichever they're comfortable with.

How it works

Behind the scenes, DomuHQ uses DeepL for high-quality EN ↔ CS translation. When auto-translate is on, every incoming message is translated to your app language; the original Czech (or English, if you've set the app to Czech) is one tap away under a "View original" link beneath each message.

Two places to toggle it

• Globally, in Preferences → Auto-translate Messages. Off here means no conversation auto-translates unless you re-enable it per-thread.
• Per message, long-press a message in any chat and pick Translate. Useful for the one Czech message in a thread where you don't want the whole conversation auto-translated.

When you might want to turn it off

• You're learning Czech and want the immersion.
• Both sides actually speak both languages and translation adds noise.
• The host's writing has nuance the translation misses (lawyer-y contract questions, sarcasm). View the original instead.

What auto-translate doesn't do

• It doesn't auto-translate documents (contracts, payment evidence). For those, use a separate translation tool or ask the host for a bilingual version.
• It doesn't translate property listing descriptions in the public listing view (those are written in one language by the host). For Czech listings, your browser's built-in translation handles it.
• It doesn't translate voice messages.

Quality notes

DeepL is well-regarded for Czech, generally better than Google Translate for the EN ↔ CS pair. Long messages translate accurately; very short messages with idioms or slang can read awkwardly. When in doubt, tap View original to check.
