How it works

Three steps. No app, no account.

Your audience opens captions the same way they'd join wifi. You start a session and speak.

Step 01

Scan the QR.

Show one QR on screen. Phones open the captions page directly — no app store, no download.

Step 02

Pick a language.

Each listener picks their own — 40+ supported. They can switch mid-session without missing a line.

Step 03

Read along.

Captions arrive under 1.5 seconds end-to-end. Reads as live, not as a delayed transcript.

Why Captio

The boring stuff, done right.

We didn't reinvent translation. We removed the friction around it — for hosts and audiences both.

Zero-friction for the audience

No app, no account, no signup. Scan, pick, read. Most competitors require a setup step before the first word lands.

< 1.5seconds

Reads as live

End-to-end caption latency stays under 1.5 seconds. Slow enough to be accurate; fast enough to feel synchronous.

$4.99/month

Honest, published pricing

Three tiers on the page, starting at $4.99/mo. No 'contact sales' gate. Compare that with $300+ per event elsewhere.

FAQ

Questions, answered straight.

How does pricing work?

Each plan includes a monthly credit allowance. Credits are consumed per minute of live captioning — the rate depends on how many languages you're translating to. You can top up credits at any time. Unused monthly credits don't roll over, but purchased top-up credits never expire.

How much does captioning actually cost per minute?

One output language: approximately $2.40/hour ($0.04/min). Each additional output language adds ~$1.20/hour. So a session with one source and two target languages costs ~$3.60/hour. See /pricing for a full credit calculator.

Is there a free trial?

Yes — every new account gets $2 in trial credits automatically. That's enough for a real 30-minute bilingual session. No credit card required to start.

Are glossaries and transcripts available on all plans?

Yes. Every plan includes custom glossaries (for domain-specific terminology like medical or religious terms) and session transcripts. Transcript retention varies: 30 days on Starter, 90 days on Growth, 1 year on Pro.

Does my audience need to install anything?

No. Audience members scan a QR code and see captions in their browser. No app, no account, no install — ever.

Can I use Captio for large conferences?

Captio currently supports one speaker per session, with audience sizes of hundreds of viewers. For multi-speaker panels or events requiring SLA guarantees, contact us — Pro plan includes a signed DPA and priority support.
