Own it outright, or rent it by the event

Boothless is a Windows desktop application that turns one laptop into a complete AI simultaneous interpretation system. It captures a speaker's microphone audio, translates it live using Google's Gemini Live API, and broadcasts the translated audio, transcript, and captions to attendees over the venue's own WiFi.

Boothless translates into more than 70 target languages, covering major European, Nordic, Baltic, Middle Eastern, Asian, and African languages. The spoken source language is auto-detected — you only choose what to translate into.

Yes. Every session produces live translated audio alongside a continuous, dual-language transcript — the original speech and its translation shown side by side as the session runs.

Yes. Attendees scan a QR code with their phone camera, and a plain web page opens in their browser with a Listen button. That's the whole flow.

No. There is nothing to install and no account to create, on either Android or iPhone. The listening page runs entirely in the phone's own browser.

Yes. Boothless can send its translated audio out of your computer's normal audio output into a classic simultaneous-interpretation delegate-unit system or a tour-guide transmitter system — the same hardware venues and rental companies already own. It's a cabling choice, not a software limitation, and it can run at the same time as the phone broadcast.

Yes, Boothless works with a built-in laptop microphone. For professional events, we recommend feeding the original audio directly from a mixer or wireless microphone receiver through a USB audio interface — direct audio produces significantly more accurate transcription and translation than capturing room sound.

AI translation quality depends heavily on how clean the source audio is. A direct feed from a mixer or wireless receiver removes room noise, echo, and distance from the microphone, which measurably improves both transcription accuracy and translation quality.
