Sources: Apple App Store listing, Live Captions (Captio AI)

XRAI Glass
Yes: Phone mid-table or extra mics

XRAI suggests putting the phone in the middle of the table, or using a Bluetooth or conference microphone (it lists a 360° mic for 8+ people). XRAI Stream shares live captions to other devices on the same WiFi.

Key differences

What actually sets them apart

Do you need glasses to use XRAI Glass?

No. XRAI says its app works on iPhone and Android without AR glasses, with captions from the phone's microphone on the phone screen. Glasses such as XRAI's own AR2 (US$699) are optional and put the captions in front of your eyes. Captio AI shows captions on your phone or tablet screen.

Which one works without internet?

XRAI Glass. Its free plan includes unlimited offline captioning on the phone, though XRAI says this is much less accurate than its cloud engines and can invent words. Captio AI needs a connection for live captions; without one it keeps recording and transcribes when the phone is back online.

Which one shows who is talking?

Both, with limits on XRAI Glass. XRAI identifies speakers only on paid plans and only with cloud engines that support it. Captio AI labels each speaker in live captions and saved recordings, and on iPhone can show the names of people whose voices you saved.

What happens to the conversation afterwards?

XRAI Glass keeps conversation history on the phone for 1 day on the free plan and 30 days on Premium. Captio AI saves each recording with its audio in a library synced to your account, and turns it into a summary, key points or to-dos. XRAI's AI assistant can also summarise, but an April 2025 help article says it needs a separate OpenAI account.

Can either one translate a conversation?

Both. XRAI Glass translates live on its paid plans, with Auto-reverse for a two-language conversation and up to 10 spoken languages at once; its pages disagree on whether the free plan translates. Captio AI translates live next to the original captions, with a two-way mode, in 60+ languages.
