Why we built it

Chiang Mai has a meetup almost every night. Most of them in English.

The people who live here, know the city and have the most to share are the least likely to be in the room. Visitors come and go, and what they know leaves with them. JoinInter turns passing through into passing on, by melting three barriers, one at a time.

๑

Understanding

Following the talk

A fast talk in a second language is hard to keep up with.

The speaker's Mac or iPhone transcribes and translates on-device. Captions stream to every phone in the reader's language, with the original one tap away.

๒

Asking

Asking a question

Even when you follow, speaking up in English in front of a room is intimidating.

Ask in Thai and the speaker reads it in English. Everyone else sees it in their own language. Ask anonymously if you like; the room likes the best questions up.

๓

Approaching

Approaching someone

Walking up to a stranger afterwards is harder still.

Wave at people who liked your question. Once they accept, you both see a name, how to spot each other and a contact, with icebreakers in your own language.

Five minutes from laptop to a room that understands itself

  1. 1Go live on your Mac

    Pick your language and the room's, press Go live. The relay starts inside the app.

  2. 2Phones scan the QR

    No app, no account. Attendees just pick a language.

  3. 3Captions, theirs

    Every phone follows sentence by sentence, in its own language.

  4. 4Ask, in any language

    Questions land in yours. Pin the best one on stage.

  5. 5Meet

    Wave at people who liked your question. Icebreakers included.

Everything in one signed app

Live captions and translation, on-device

Speech recognition and translation run on your Mac or iPhone. Audio never leaves the room; the relay only ever sees text.

54 speech locales. Apple Translation plus NLLB-200 on the Mac for Burmese, Lao, Khmer, Shan and more.

Q&A 2.0

Anonymous questions and likes, translated threads, and merge suggestions across languages: three people asking the same thing become one.

Pro

Polls the quiet half answers

Choices, word clouds or a 1 to 5 scale, translated into every room language. Fire a quick poll with ⌃⌥⌘P.

Pro

OBS, Zoom, NDI

A browser source with a transparent overlay, a virtual camera, or NDI to a vision mixer. JoinInter is a source; OBS does the encoding.

Pro

The event, in your pocket

Standalone runs a whole session from an iPhone or iPad over its hotspot: yoga classes, walking tours, monk trails. Or pair phones as companions.

Community + Pro

Meet & icebreakers

Questions connect people. Icebreakers grounded in the talk, written by your own AI CLI over local MCP, each in the reader's language.

Pro

Recap & export

A one-page recap for attendees in their language. For you: every line, poll and question as JSON, CSV, PDF or Markdown.

Pro

One link, any room

The relay is built in and starts with Go live. A public link in one click, a branded event link, or fully offline over Wi-Fi or a phone hotspot.

Stage canvas

One stage for every screen in the room

Slides, captions in three languages, the join code, the timer, the pinned question and live polls, composed as zones on a 16:9 stage. Rules decide what opens when.

Questions

Asked in every language

ถามได้ทุกภาษา

Do attendees need to install an app?

No. Attendees scan a QR code and JoinInter opens in their phone's browser. They pick a language, read along, ask and meet. No account, nothing to install.

Does audio leave my Mac?

No. Speech recognition and translation run on the presenter's Mac or iPhone. The relay only ever sees text, keeps rooms in memory and forgets them after 12 hours idle.

Which languages does live translation support?

Speech input covers 54 locales. Apple Translation covers 19 languages (38 with regional variants) on-device, and the Mac adds NLLB-200 for languages Apple lacks, such as Czech, Burmese, Lao and Khmer.

What does the $30 lifetime license include?

Every Pro feature in the same signed app, and all 1.x updates. One purchase, no subscription, no account. The key verifies offline, so it works at events with no internet.

Does it work without internet?

Yes. Run the relay over the venue Wi-Fi or a phone hotspot and everything except the public link works offline: captions, translation, Q&A, polls and Meet.

How many attendees can join?

The built-in relay handles a full meetup room; we test 200 phones at once. Larger audiences are what Hosted and Enterprise are for.

Can I present from just an iPhone?

Yes. Standalone mode runs a whole session from an iPhone or iPad over its own hotspot. AI icebreakers and the extended NLLB languages need a Mac.

Let the whole room in.
