Answers to commonly asked questions. If yours isn't here, please get in touch.

We support clinicians and healthcare organisations across three areas: patient communication (including in multiple languages), peer-to-peer engagement with colleagues and training materials, and professional profile content to build practice visibility.

Four to six weeks from first call to live library. Your time: about one hour in person for filming plus one to two hours remotely to review and approve.

Yes. You have two rounds of review during which you can provide time-stamped feedback to request updates.

Yes. Send us any images, branding or video clips you'd like included and we'll integrate them. If you don't have your own, we have a stock library you can choose from.

Our internal scripting tool has been trained on the hundreds of clinician videos we've produced. Working from whatever inputs you have (articles, slides or initial thoughts), we'll build scripts that are around 80% there and refine the last 20% with you.

Yes, but quality will be lower than a purpose-shot filming session, particularly on lip-sync. Avatar accuracy depends on how the original footage was captured and most existing footage isn't shot to those specifications.

Yes. We'll still need to attend the filming session but we can brief your videographer on how to capture the right footage to generate a high-quality avatar.

Software exists that does this. We've reviewed it and chosen not to offer it. Translation accuracy is harder to control on existing footage and the result is visibly and audibly manipulated. That's not the standard we set for clinician-led content.

Yes. The typical cadence is a quarterly review and refresh, included in your ongoing engagement. If clinical guidance changes between reviews, we'll flag it and update content out of cycle so patients are never seeing outdated information.

A typical library launches with 10 videos. You can add more over time, either at around one video per month within your existing engagement or as a bespoke project to produce a larger batch in one go.

We cover all commonly requested languages with tone-matched lip-synced delivery. If there's a specific language you need for your clinic, contact us directly. We typically recommend no more than two or three translations per clinic, focused on the audiences you serve most.

Avatars are created using Synthesia, a UK-based platform we chose for its generative AI capabilities and industry-leading approach to security and data protection.

Synthesia operates at enterprise security standards: encrypted data storage, GDPR-compliant servers in the EU, SOC 2 Type II, ISO 27001 and ISO 42001:2023 (the global standard for safe and responsible AI).

Your avatar cannot be created, modified or used without your explicit consent. Consent must be recorded live on video and matched to your face using facial recognition.

You retain full ownership of your likeness at all times. Synthesia hosts the avatar on our platform under contract to us; your consent governs how it can be used.

Your avatar carries a very close likeness to you. Some head movements may not be fully natural and most viewers recognise within a couple of videos that it isn't a live recording. Every video is tagged as AI-generated so there's no ambiguity.

Yes. We typically capture multiple recordings on your filming day to give you variation in look, setting or attire. You can also schedule additional filming as part of ongoing support.

When your contract with 4Cori ends, for any reason, your avatar and all biometric data are deleted within 30 days, in line with UK GDPR.

Your digital twin can present educational and informational content covering: diagnoses, treatments, common conditions and procedures performed by licensed practitioners; information about a medical institution; and educational content on medicines and medical devices.

Yes. We don't create: unverified public health emergency content; misleading or unauthorised claims about diagnostics, treatments or procedures (including miraculous treatment claims); or content that contradicts expert consensus on safe medical practice. Our model is educational not promotional. We don't produce branded promotional content for prescription medicines or medical devices.

Every patient facing video is created by a registered medical professional who reviews and approves their own content before publication. On top of that, every video goes through an automated moderation process.

None. 4Cori does not capture or store patient data and is not a processor of patient personal data under UK GDPR. Where videos include interactive features such as PROMs surveys, responses go to your systems, not ours. Viewer engagement data within the platform (plays, completion, geography) is anonymised.

Avatar and video data is held on Synthesia's GDPR-compliant servers in the EU. Hosted videos sit on Vimeo, which holds SOC 2 Type II and ISO 27001 certification.

No. Clinician subscriptions run on a rolling basis and you can exit at any time with one month's notice. Organisational contracts are agreed at the point of engagement.

You receive your latest videos in MP4 at 1080p and retain full ownership of your video content. Your avatar and biometric data are fully deleted within 30 days of cancellation.

Your library lives on its own branded subdomain (for example, mskclinic.4cori.com). You can also embed any video or the full library into your existing site. Updates propagate automatically.

Yes. Video links can be triggered through your existing booking and patient communication systems.

Whatever channel works for your patients. Shareable link, QR code, email, SMS or embedded directly into your website. Many practices use multiple routes depending on the moment in the patient journey.

Your library is built to be found and accurately understood by both traditional search engines and AI assistants.

For Google and other search engines, every video has structured metadata generated from its transcript and your practice details.

For AI assistants like ChatGPT, Claude and Perplexity, your library publishes a dedicated summary file (llms.txt) that tells these assistants who you are, what topics you cover and where to direct patients. When a patient asks an AI assistant about a condition you treat or a procedure you perform, the assistant can read and cite your library.
