Speakers in their language, audiences in theirs
Float live translated captions over the slides, movie-subtitle style, and open as many per-language caption windows as your venue screens need.
Extension — captions right on the page, even over fullscreen presentations
Newey AI transcribes and translates the speaker with about a second of latency, floating the result over the presentation like movie subtitles. There is no interpreter booth or receivers to rent — one browser handles the setup, and the audience just watches the stage screen as usual. This use case is fully available today.
When to use it
- International conferences and meetups with mixed-language speakers and audiences
- Town halls and all-hands watched by offices in several countries
- Demo days and IR pitches in front of international investors and judges
- Guest lectures, seminars, and workshops with international attendees
Pre-event checklist
Three things before you take the stage make the day run smoothly.
Register proper nouns in the glossary
Add speaker names, company and product names, and the technical terms from session titles. The source=translation format forces the exact translation you specify; a plain word boosts recognition. Describe the event in the context field — it is injected as a translation hint alongside the entries.
Run one rehearsal
Speak for a minute or two at real presentation pace and check latency, line count, and font size. Style changes apply live, but it is best to settle the caption position during rehearsal.
Check the mic and mixer input
If you are taking audio from the venue mixer, pick that input (your audio interface) as the microphone device under advanced settings. Clean speaker audio is what makes recognition quality.
On the day
Start in Caption mode
Pick Caption mode in the console and pin the input language to the speaker's language (steadier than auto-detect). Choose your translation languages and press Start — an always-on-top overlay window (PiP) opens.
Place the overlay on the slides
Drag the overlay window to the bottom of the presentation screen. The audience sees slides and captions on a single screen.
Or go Stage mode
If you have a dedicated caption screen, Fullscreen mode works better — a large translation over a black backdrop with the source kept small. Press ESC to exit.
Need more languages? Open new windows
Use the New window button on the preview card to open per-language caption windows and place a different language on each screen. Three screens, three languages — the price stays the same regardless of language count.
Adjust while live
Font size, line count, and display mode all apply instantly during the session. Space pauses, Shift+Space stops.

Details & tips
Pin the input language
If you know the speaker's language, pin it instead of using auto-detect — recognition is steadier.
Sentence display mode
On stage, the calm Sentence mode reads best. Prefer a live, flowing feel? Use Streaming mode.
3–4 caption lines
If long sentences get cut off, raise the caption line count to 3–4. Keep source size on Small so the translation stays the hero.
Background scrim
Over bright slides, turn on the background scrim for readability. Turned off, an outline keeps captions legible.
Limits & requirements
- The overlay works on desktop Chrome/Edge 116+ and Firefox 151+ (Document PiP), and on Safari 18+ as a simpler floating window. On other browsers, use stage mode instead.
- On macOS, the overlay cannot appear above Keynote/PowerPoint fullscreen playback — play in a window (Keynote: Play in Window) or send stage mode to a separate screen.
- The active glossary set is injected once at session start — edits made during a live session apply from the next session.
- Informing attendees that the talk is being transcribed and obtaining consent is the organizer's responsibility.
Whatever you watch, whoever you talk to
Let the captions handle the language. One account, three seconds to start.
