Live Captions for
Webinar Attendees

MirrorCaption gives webinar attendees live captions in 50+ languages directly on their phone — no Zoom or Teams host configuration required, no app download, no prior coordination. Open Chrome, choose your language, and read the speaker's words as they say them.

Every major webinar platform lets the host enable captions. That's the catch. On Zoom, the feature is off by default and the host must opt in before the meeting starts. On Microsoft Teams, the organizer controls the same toggle. If they haven't enabled it — or if you're attending an external event hosted on a platform you have no control over — there are no captions available to you at all. MirrorCaption solves this from the attendee's side, not the host's.

Why Webinar Captions Often Fail Attendees

When you join a webinar as an attendee, your caption options depend entirely on what the host set up. That creates three predictable failure points:

• The host didn't enable them. On Zoom, Automated Captions are disabled by default. On Google Meet, availability depends on the host's Workspace plan and settings. In a large external webinar with hundreds of attendees, you can't ask the presenter to change their account configuration mid-session.
• The platform supports limited languages. Built-in captioning on most platforms is English-first. Broader language support varies by plan tier and region. Non-native speakers attending an English webinar often get partial help at best; speakers of Arabic, Japanese, or Mandarin may get nothing usable.
• You're on a phone. Some platforms show captions in small, unreadable text in their mobile app layout. Others don't surface the caption toggle in the mobile view at all.

For context: the World Health Organization estimates more than 5% of the global population has disabling hearing loss. Add the much larger group of non-native speakers attending content in a second language, and the share of webinar attendees who benefit from captions in their own language is significantly higher than platform defaults serve.

According to research by Verbit, captioned webinars achieve 25% higher viewer retention. And according to Airmeet's event research, 67% of attendees say captions help them maintain focus. The demand is real — the host-dependent supply isn't keeping up.

Who Needs Live Webinar Captions on Their Phone

The following are representative scenarios illustrating where attendee-side captions make the difference.

How to Get Live Captions on Your Phone During a Webinar

Three steps. No host coordination required.

1. 1
   Open MirrorCaption in Chrome on your phone. Go to mirrorcaption.com/app in Chrome. Creating a free account takes under a minute. You get 1 hour of live transcription — no credit card, no monthly reset.
2. 2
   Choose your languages and start Talk mode. Select the language the speaker will use (e.g., English) and the language you want to read in (Spanish, Japanese, French, German — 50+ options). Tap Start. Talk mode uses your phone's microphone to capture audio.
3. 3
   Position your phone toward the audio source. If the webinar is playing on a laptop nearby, set your phone on the desk facing the speakers. If both apps are on the same phone, keep the webinar volume audible so the microphone picks it up. Captions appear word by word as the speaker talks. Tap any translated word to see the exact source phrase it came from.

How MirrorCaption Compares to Platform Captions

Platform captions are the right first choice when the host enables them. Here's where they fall short for attendees, and where MirrorCaption covers the gap.

Platform caption availability and language support vary by tool and account tier. Check each platform's own documentation: Zoom Automated Captions, Microsoft Teams live captions, Google Meet captions.

What You'll See During the Webinar

MirrorCaption's mobile view is designed for the split-attention scenario: glance at captions, look back at slides, follow the conversation. Here's what the live session gives you.

• ✓
  Word-by-word captions with no lag — MirrorCaption's streaming transcription delivers captions continuously as the speaker talks, without waiting for a sentence to finish before displaying anything. You read the content while it's still being spoken, not after a processing pause.
• ✓
  Original text alongside your translation — the source transcript and your translated captions appear in a stacked view on mobile. Tap any translated word to reveal the exact source phrase behind it — useful for verifying a technical term, catching a name, or checking a number you weren't sure about.
• ✓
  Speaker detection — multiple voices are automatically labelled (Speaker 1, Speaker 2), making panel discussions and Q&A sessions easier to follow. You can rename speakers during or after the session so the transcript is readable later.
• ✓
  Export when you're done — copy the full session transcript as plain text or Markdown. Use it for meeting notes, to share with a colleague who couldn't attend, or as a searchable record of what was discussed. The difference between a live caption and a saved transcript is covered in detail in live captions vs transcripts.
• ✓
  Optional AI summary — generate a structured summary of the session's key points after the webinar ends. Useful if you joined late, stepped away mid-session, or want a quick digest to send your team.
• ✓
  Vocabulary builder — if the webinar introduces unfamiliar terms, save them with a tap. MirrorCaption maintains a personal vocabulary list from your sessions — particularly useful for language learners attending content in their target language.

What It Costs

All three MirrorCaption tiers include Talk mode on mobile and access to all 50+ languages.

• Free — 1 hour of hosted transcription, one-time with no monthly reset. No credit card required. Full access to Talk mode, all 50+ languages, speaker detection, transcript export, and vocabulary builder.
• Annual — €54.99/year — everything in Free, plus 100 hours of hosted transcription credit for the year. Priority support and product updates as they ship. Voice Packs (sold separately) cover any hours beyond the included 100h.
• Premium — €99 one-time — everything in Annual, plus a one-time purchase with no recurring subscription. 200 hours of hosted transcription credit included. All future product updates with priority access as they ship. When the included 200h run out, Premium customers get the lowest per-hour rate on Voice Packs (sold separately, starting at €2.99 for 5 hours). This is the only tier that never auto-renews.

For comparison, Otter.ai's Pro plan is $16.99/month — $203.88 per year — and focuses primarily on English transcription with limited translation support. MirrorCaption Premium costs less over two years, covers 200 hours upfront, and stops there: no further charges unless you choose to add Voice Packs.

Frequently Asked Questions

Can I get live captions on a webinar if the host didn't enable them?

Yes. MirrorCaption runs in your browser and captures audio through your phone's microphone in Talk mode. No host action, no platform permission, and no bot joining the call is required. You control your own caption experience independently of what the organizer configured — or didn't configure.

Does MirrorCaption Talk mode work on mobile phones?

Talk mode works in Chrome on mobile. It uses your device's microphone to capture audio. Chrome on Android is recommended for the best experience. Chrome on iOS may also work, but performance can vary by device and iOS version. We recommend testing with your free 1-hour session before a high-stakes webinar so you know what to expect on your specific device.

Will the webinar host know I'm using MirrorCaption?

No. MirrorCaption opens in a separate browser tab and uses your device microphone. It never joins the meeting as a visible participant, never sends a bot that appears in the participant list, and never posts anything to the meeting chat. From the host's perspective, you're just another attendee in the audience.

Which languages does MirrorCaption support for webinar captions?

MirrorCaption supports 50+ selectable languages including Mandarin, Japanese, Korean, Spanish, French, German, Arabic, Hindi, Portuguese, Russian, Hebrew, Turkish, and more. You choose the source language (what the speaker is saying) and your target language (what you read) as two independent settings — so you can, for example, listen to English and read captions in Japanese.

How much does MirrorCaption cost?

Free to try: 1 hour of hosted transcription, no credit card, no monthly reset. After that, the Annual plan is €54.99/year with 100 hours of hosted transcription included. Premium is €99 one-time — a single payment, no subscription — with 200 hours included, all future product updates with priority access as they ship, and the lowest per-hour Voice Pack rate when you need more hours. Voice Packs are sold separately on all plans.

Is my audio recorded or stored anywhere?

No audio is stored on MirrorCaption servers. Audio streams through your browser to a real-time transcription service and is discarded immediately after processing — it's never saved server-side. Transcripts are stored only in your browser's local storage, where you own them. MirrorCaption retains only usage data needed for billing (minutes consumed), not the content of your sessions.
