Free to start.
Hi Product Hunt! 👋
I'm Nikolay, a solo developer. I built Lingua because I moved to an English-speaking country and needed to hold real conversations — at the doctor, at the bank, on the phone — not just translate phrases. Every app I tried made me pass the phone back and forth and wait.
Lingua just listens and interprets both ways in real time, hands-free: you speak your language, the other person hears theirs about 2 seconds later. Under the hood it streams audio to realtime speech-to-speech neural networks over WebSockets.
Along the way it grew into more:
• A messenger with live-translated voice & video calls — each side hears their own language
• An AI memory that remembers anything you tell it
• A discreet voice prompter for interviews and meetings
• A fully offline on-device mode for flights and roaming
It's free to start. I'd love your feedback — especially which language pairs you'd want next. I'll be here all day answering questions!
The two-second translation delay feels almost natural in conversation, which I did not expect. Tried it Spanish to Japanese with a friend and it just worked without me thinking about it.
The two-second voice translation feels genuinely snappy, not laggy like other apps I've tried. The AI memory part is a nice touch too — finally something that actually remembers context between sessions.
