Voice-only language exchange

Stop typing.

idiom matches you with someone who speaks the language you're learning — and is learning yours. Then we lock the keyboard. No typing, no translations on tap. Just voice.

Apps teach you grammar. Reading teaches you vocabulary. Only speaking teaches you the language.

The reason most people quit language apps isn't the app — it's the moment they meet a real human and freeze. Months of flashcards. Zero ability to order coffee.

The shortcut isn't a shortcut. Every translation tap, every typed reply, every read-aloud lesson is a safety net that postpones the only thing that actually works: opening your mouth.

idiom removes the net. Voice notes and live calls — that's it. No keyboard. No copy-paste. No "let me Google that word."

It's harder. That's the whole point. Speak, mess up, get corrected by a human who's messing up your language right back. Two weeks in, you'll talk. That's a promise.

Three steps. No keyboard.

01

Match the pair

Pick what you speak natively and what you're learning. We find someone whose pair is the mirror of yours.

02

Send a voice note

Open with hello in their language. They reply in yours. Each of you teaches what you know best.

03

Then jump on a call

When you're ready, tap to go live. 7-minute daily prompt to break the silence. Voice only, both ways.

One free tier. One paid tier. That's it.

The obvious ones.

When does idiom actually launch?
Alpha opens when the waitlist hits 1,000 — likely 4–8 weeks from now. App Store launch follows after a 3-month alpha. Waitlist signups get priority access and 3 months of Pro free.
Is it really only voice?
Yes. Free tier has zero text and zero subtitles. That's the product, not a limitation. Pro adds text chat and subtitles for moments you need them, but the philosophy stays voice-first.
What if I don't speak well enough yet?
You don't have to. Voice notes mean you can record, listen, re-record. Your partner is a learner too — they expect mistakes. That's the trade.
How does matching work?
By language pair, level, and time zone. If you speak English and learn Spanish at B1, we find someone who speaks Spanish, learns English, and overlaps with your schedule.
What about privacy?
Voice notes stay between you and your partner. Calls aren't recorded by default. You control what you share and can block or unmatch anyone, anytime.
Will it be on iOS and Android?
iOS first at App Store launch. Android follows shortly after. Alpha will be invite-only via TestFlight (iOS) and a web-based version for everyone else.
