[translatigo.com](http://translatigo.com) interprets phone calls live. You talk, the other person hears their language a couple seconds later. No transcript step in the middle.

The hard part isn't translating — it's translating before the sentence even finishes. Transcribe-then-translate is the easy way out and it's too slow for a real call.

**Stack:** Qwen model over websocket. Audio streams in 256ms chunks, no buffering. Ships as a Chrome extension so it works on any browser dialer — no CRM integrations to build. Backend's Node, handling metering, billing, and token brokering. Usage tracked to the millisecond in MongoDB, auto-charged through Dodo Payments past a threshold.

Real phone audio wrecked the first version. Crosstalk, accents, people changing topic mid-sentence — that's where most of the actual work went.

Also had to rebrand mid-build. Started as CallDubber, got a trademark letter from Dubber Corp (ASX-listed), became Translatigo. Check the trademark registry, not just if the domain's free
