Live Caption AI
Live Caption, Inc.
Provides live speech captions on a device and shares caption sessions with an audience’s phones.
What Live Caption AI does
Live Caption AI displays live speech captions on iOS, Android and the web. Its Free plan provides on-device captions and viewing of shared sessions. Professional adds cloud recognition, caption broadcasting, custom vocabulary, translation, summaries and exports. An audience can scan a QR code to read the presenter’s captions on their own phones. Translation time has a monthly allowance even though Professional captioning and broadcasting are described as unlimited.
How it compares
On-device captions, like other in-person captioning apps
Live Caption AI's Free plan offers on-device speech-to-text without an app account. NALscribe and Google Live Transcribe are other options for in-person captions, with offline modes.
Presenter broadcasting rather than Ava-style group microphones
Professional lets an audience scan a QR code to read a shared caption session. Ava also supports shared sessions, using participants' devices to identify speakers in a group conversation.
Paid translation, like Ava, with a separate allowance
Professional includes eight hours of translation a month, with extra time sold as credits. Ava also offers translation on paid plans; compare the translation allowance separately from ordinary caption time.

App Store ratings & reviews
Praise
- A March 2025 review valued sharing captions to an audience through a link or larger display; this is a user report rather than a measured current-version test.
Complaints
- A September 2024 reviewer objected to paid access. This predates the current pricing/free-tier documentation and does not establish current plan limits.
Google Play ratings & reviews
Praise
- A July 2024 version-1.0.2 review valued audience caption sharing, while another reviewer offered general praise in October 2025. Neither establishes caption accuracy or speaker-label performance.
Complaints
- Reviews from June 2025 and June 2026 described blank or nonloading screens, including Android versions 1.0.2 and 1.0.6; one January 2026 report on 1.0.6 described delayed transcription.
- An October 2026 reviewer objected to paying for access; current plan details must come from the publisher, not the review.
Mixed reports
- A reviewer updated a May 2025 version-1.0.2 complaint after successful classroom use and developer contact, while noting slow support responses. The earlier problem should not be presented without its reported resolution.
