Enterprise AI dubbing with human-in-the-loop quality review

Visit official site →

About

Papercup is an enterprise-focused AI dubbing service that combines proprietary voice synthesis with human translators who verify tone and accuracy. Founded in 2017 in the UK, it has dubbed content for Sky News, Discovery, and Business Insider, and offers custom API integrations for production pipelines.

Pricing is per-minute and quote-based rather than public self-serve, so it is built for companies with localization budgets rather than individual creators.
