People are talking

Used by communities, conferences, and classrooms across the country

We used to have a volunteer whisper-translating from the front of the room. Now our Spanish-speaking attendees can read captions on their phones in real time. It's changed everything.

Setup took two minutes. We projected it on the big screen and shared a QR code. Our annual conference had 40 people following along on their own devices.

Event Coordinator, Mesa AZ

One of our attendees was in tears. For the first time she could fully follow along with a Spanish-language speaker without needing a separate interpreter beside her.

Accessibility Coordinator, Provo UT

Honestly I was skeptical about AI translation quality, but CaptionCast handles our bilingual community meetings surprisingly well. The setup is dead simple.

Frequently asked questions

Everything you need to know to get started.

How accurate is the translation?

CaptionCast uses Deepgram Nova-3 for transcription and a modern GPT model for translation. Accuracy is highest with a clear mic signal and a single speaker. Latency is typically 2–5 seconds end-to-end.

What languages do you support?

CaptionCast supports 12 languages: English, Spanish, French, German, Italian, Dutch, Portuguese, Russian, Chinese (Mandarin), Japanese, Korean, Arabic, and Hindi. Every translation pair routes through English — for example, Spanish → French is handled Spanish → English → French. Pick the direction for each meeting on the control panel.

Do I need special hardware?

No. CaptionCast runs entirely in the browser — Chrome or Edge recommended. A laptop's built-in mic works; a wired lavalier or a direct PA line-out gives the cleanest captions.

How does the cost work for a 100-person room?

CaptionCast bills by minutes streamed, not by viewer — so price-per-attendee shrinks as your room grows. For a 100-person room:

  • Growth at $19/mo works out to ~$0.19 / person / month.
  • Pro at $49/mo works out to ~$0.49 / person / month.

For nonprofits, churches, and accessibility teams that need to justify the line item, that's typically less than the cost of one printed program.

How are minutes counted and what happens when I go over?

Only time with the mic actively recording counts. Your current usage is visible at /org/usage. Your existing transcripts and recordings are always accessible; upgrading to a larger plan takes effect immediately, and prorated charges are handled by Stripe.

Can attendees view captions on their phones?

Yes. Share the display URL or project the QR code. Attendees open it in any browser — no app install needed. Each viewer can pick their own language (on multi-language meetings), their own font size, and their own theme.

Can I record the session for later playback?

Every active meeting records its raw audio and transcript. After the meeting ends, open /meetings/:id/playback to play the audio back with the captions synced. Transcripts can also be exported from the meeting detail page.

Is there an iOS or Android app?

Not yet. Viewers use any mobile browser — there's nothing to install. Operators use a laptop or desktop browser (Chrome or Edge) because CaptionCast needs WebAudio access to the mic.
