VoxFlux review
Browser-based live captions with operator monitoring, display controls and pay-as-you-go credits.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VoxFlux turns live event audio into real-time captions and AI-translated captions. It is aimed at AV teams, event organisers and production companies running conferences, hybrid events, broadcasts or other productions. Operators configure sessions in a browser using a microphone, USB audio interface or mixer input, then route caption output to screens, streams, relay displays or mobile viewers. Its focus is practical event captioning rather than a broad accessibility or event-management suite.
The workflow combines operator oversight with flexible display output. A live preview and audio input monitoring help operators follow a session, while controls cover typography, colour, position, width and fullscreen display. Output modes include Live Type, Auto Scroll and Clean Output; browser links can feed screens, streams, relay displays and confidence monitors, and a mobile viewer link supports private caption viewing. TXT transcripts and SRT subtitle files are downloadable. This set of controls suits teams that need to adapt captions to a production setup, though the listed product information does not establish an integration ecosystem.
Pricing uses one-time credit packages rather than a monthly subscription. Live captioning costs $25 for 1 hour, $115 for 5 hours or $200 for 10 hours. AI translation is separately priced at $35 for 1 hour, $160 for 5 hours or $300 for 10 hours. These packages make the cost structure visible for discrete sessions, but buyers should account for translation as a separate purchase. VoxFlux fits small and mid-market teams with occasional event captioning needs and straightforward browser-based controls; organisations that require named integrations or a subscription plan should compare alternatives.
