Papercup
Papercup is RWS's AI dubbing orchestration layer for TV, film and digital content. It pairs AI voice generation with expert human review so studios, broadcasters and streamers can localise catalogues at scale.
What is Papercup?
Papercup is RWS's AI dubbing orchestration layer, built for TV, film and digital content. RWS acquired the Papercup intellectual property (announced in 2025), and papercup.com now redirects to the RWS product page - the name survives as a product, not as a standalone company. The service plugs into a customer's existing media platforms and gives one secure place to manage multilingual video, with three stated aims: tiered localisation strategies, faster release cycles and fully managed delivery. Technically, the headline feature is XLPT - cross-lingual prosody transfer - which carries tone, rhythm and emotional nuance from the source language into the target one; automatic speaker detection keeps characters distinct across scenes. Work runs through a six-step pipeline from transcription to platform-ready export, with transcript and translation editing available to fine-tune synchronisation, audio accuracy and lip sync. Behind the models sits the RWS human network: over 43,000 premium linguists across 197 countries, 70+ years of localisation and 80+ of the world's 100 largest brands. Related services extend beyond AI dubbing to human dubbing and voice direction, subtitling and SDH, captioning, audio description, post-production and audio engineering, localised graphics and custom AI solutions. It is an enterprise offering: no public pricing, no self-serve account, no free trial.

When to use Papercup / When not to
A quick filter to help you decide if Papercup is the right fit.
When to use Papercup
- Broadcasters and streamers with large back catalogues to localise at a controlled cost
- Studios handling premium titles that need a full production workflow rather than raw machine output
- Media organisations testing a new market before committing to a full localisation investment
- Teams with time-sensitive content - sports highlights, factual programming - that must ship in days rather than months
- Corporate and L&D teams localising training modules, eLearning, brand video and product demos
When not to use Papercup
- Individual creators and small studios: there is no self-serve account, no free trial and no public price list
- Anyone who wants to buy online, since every project goes through the RWS sales team first
- Highly creative or emotionally nuanced work, where RWS itself recommends adding professional human voice actors
- Developers looking for an API or per-minute pricing: neither is exposed on the product page
- Buyers who need to compare costs upfront, as no tier, rate or currency is published anywhere

Pros & Cons
Pros
- Backed by the RWS network: 43,000+ linguists in 197 countries, 70+ years of localisation, 80+ of the world's 100 largest brands
- XLPT preserves tone, rhythm and emotional nuance - the main technical differentiator claimed
- Expert human validation at every stage rather than a fully automated pipeline
- Governance, compliance and brand safety built into delivery, sized for global distribution constraints
- Turnaround measured in days rather than months for time-sensitive content
- Adjacent services available beyond AI dubbing: subtitling, SDH, audio description, human dubbing and voice direction
- Solid legal framework: GDPR commitment, DPA, EU and UK representatives, US Data Privacy Framework certifications
Cons
- No public pricing, no plans and no rate card: the cost cannot be estimated without contacting sales
- No free trial and no self-serve account; the only entry point is a contact form
- papercup.com no longer hosts a site of its own - it redirects to a page on the RWS corporate site
- No list of supported languages is published
- No named third-party integrations
- No public API documentation found
- Enterprise positioning that puts the tool out of reach of individual creators and small teams
Pricing & Plans
No pricing is published. The product page shows no plan, no tier, no currency and no starting price, and neither a free plan nor a free trial is mentioned. The model is enterprise quote-based: the only call to action is to contact the RWS team, which scopes each project before issuing a quotation. The commercial argument put forward is that AI voices shorten turnaround times and reduce costs compared with traditional voiceover, but no figure is published to support it.
Data, GDPR & hosting
A consolidated view of how Papercup handles your data.
GDPR overview
GDPR commitments are explicit and documented at group level. RWS states it complies with the EU GDPR (2016), the UK Data Protection Act 2018, PIPEDA, the CCPA, the LGPD and Australia's Privacy Act 1988. An Article 27 EU representative is named - Moravia IT s.r.o., Brno, Czech Republic - alongside a UK representative, RWS Holdings Limited in Maidenhead. Privacy requests go to a single contact: Christel Cao-Delebarre, Group Head of Global Privacy, privacy@rws.com, +44 (0) 1753 480 200; CCPA requests use privacy@rws.com or +1 888 351 2210. International transfers outside the EU, EEA and UK are covered by appropriate safeguards, with a copy of the intra-group transfer agreement available on request. Three US entities - RWS Life Sciences Inc, SDL Inc and SDL XyEnterprise LLC - are certified under the EU-U.S. DPF, its UK Extension and the Swiss-U.S. DPF. The notice is version 1.4.
Who owns the data?
RWS Holdings plc and its subsidiaries act as data controller for the personal data collected through their websites, applications and services. When RWS is engaged under a standalone Data Processing Agreement, it acts as data processor or sub-processor for the personal data its customers supply, and the DPA terms take precedence over the privacy notice; in any conflict between that notice and a customer contract or DPA, the agreement prevails. On the production side, the customer keeps control over the voice, accent, style and delivery of the dubbed output. No separate ownership clause specific to the Papercup product is published.
Reuse rights
The privacy notice grants end users no reuse right over RWS-held data; it describes how RWS itself uses and shares personal data. Data may be shared with partners and resellers in countries where RWS has no office, with sector partners, and with service providers handling communications, analytics, marketing, payments, debt recovery, customer service and certification. Hosting and SaaS providers are named only generically, with AWS and Microsoft cited as examples. RWS states it will not sell, trade or rent personal data to unaffiliated third parties without express permission, and will not share it beyond these cases without consent. If RWS sells a business or assets, personal data may be among the transferred assets. Cookies are deployed across the sites under a separate cookie notice.
Data retention & training
Hosting summary
No hosting country or region is specified for the Papercup product itself. The RWS privacy notice names hosting and SaaS providers only generically, citing AWS and Microsoft as examples of the IT service providers used in the ordinary course of business, without tying any of them to a particular data centre or jurisdiction. Personal data may be transferred outside the country of residence, including outside the EU, EEA and UK, under appropriate safeguards; a copy of the intra-group transfer agreement is available on request. Three US entities are certified under the EU-U.S. Data Privacy Framework, its UK Extension and the Swiss-U.S. DPF. As a network observation rather than a product fact, the papercup.com domain resolves to an address in AS16509 Amazon.com (anycast, Seattle, US), which indicates where the redirect is served from, not where customer content is stored. Anyone with data residency requirements should raise them during the sales conversation.
Things to keep in mind
Risks and trade-offs to weigh before adopting Papercup.
- Papercup no longer runs its own site: papercup.com 301-redirects to www.rws.com, so the brand survives as a product name, not as an independent company
- No price, no plan and no commitment period are published, which makes budgeting impossible before a sales conversation
- Voice cloning: RWS claims ethically sourced voices and a licensing framework, but no voice consent policy is published on the product page
- The privacy notice covers the whole RWS group rather than the Papercup product specifically
- Personal data may be among the assets transferred if RWS sells a business or assets
- International transfers outside the EU, EEA and UK are anticipated, with safeguards the page does not detail
- No statement is made about whether customer content is used to train models
Setup & Integrations
Technical difficulty
There is nothing for the user to install: Papercup is delivered as a managed service, with RWS specialists running onboarding step by step after the first sales contact. The real effort sits elsewhere. The product is designed to plug into a customer's existing media platforms, so a media supply chain integration project falls on the client side, alongside the review and sign-off cycle. Difficulty is therefore organisational and commercial rather than technical for the end user: expect a procurement process and an integration workstream, not a setup wizard.

Should you pick Papercup?
Papercup is now an enterprise dubbing product inside the RWS catalogue rather than a company of its own, and that shapes both its strengths and its blind spots. The strength is the pairing: XLPT prosody transfer, automatic speaker detection and AI voices on one side, a network of 43,000+ linguists and decades of localisation practice on the other, with human review kept in the loop instead of removed from it. The weakness is opacity. No price, no plan, no supported-language list, no API documentation and no site of its own - papercup.com simply redirects to RWS. For a studio, broadcaster, streamer or large media organisation with a catalogue to localise and a procurement process to match, that is a reasonable trade. For an individual creator or a small team, there is no way in at all.
