Hey Product Hunt! 👋 I'm Prakash, the solo founder of TellAcross.
TellAcross is real-time, voice-to-voice translation for live calls. You start a call and share a link — the other person joins from any browser with nothing to install. You each speak your own language and hear the other in theirs, in under a second, in a natural voice.
I built it because every other tool I tried was a caption plugin that BOTH people had to install. You can't ask a job candidate, a customer, or a new client to set up software before a call. A link fixes that — they just click and you understand each other.
A few things that make it different: it remembers the conversation (names and context carry across sentences), covers 100+ languages including full Indic support, shows a live transcript, and has modes tuned for business, medical, legal and education.
It's live and free to try (10 minutes/month, no card). I'd love your feedback — try a quick call in a language you don't speak and tell me where it surprises you or where it breaks. I'll be here all day answering everything. 🙏

One thing that would make this a no-brainer for me: let me save a few "preset" language pairs and domains so I don't have to reconfigure medical vs casual mode every single call. Maybe even pin the last-used setup to the home screen.

@metehdea Mete — love this, and good news: language presets already exist under the hood. 🙌 You can save something like "Spanish ↔ English · Medical" or "Mandarin ↔ English · Legal" and reuse it. The piece I'm adding is exactly what you described — pinning the last-used setup (language pair + domain mode) to the home screen so starting a call is one tap. Quick q so I build it right: would you want presets saved per-person, or shared across a whole team?
And if you give it a spin in the meantime, I'd genuinely love to hear where the current setup slows you down — happy to ping you the moment presets ship.

Tested it on a quick call with a friend who speaks Hindi and the translation came through almost instantly, sounded pretty natural too. Genuinely impressed it needed zero setup on their end.

@lyas1059603 Hi Ilyas, this made my day — thank you! 🙏 "Zero setup on their end" is the whole reason I built it (you can't ask the person you're calling to install anything), so hearing it land on a real Hindi call means a lot. Curious — what would you reach for it for? Work calls, family, something else? Always trying to learn where it's most useful.

love how it just works in the browser, no app needed. the under a second latency is genuinely impressive for voice translation

@ramazanersfoal Thank you! 🙏 The "just works in the browser, nothing to install" part was the hardest to get right — and the thing I'm proudest of, because the person you're calling shouldn't have to lift a finger. Keeping it under a second took a lot of tuning too. Really appreciate you trying it
