Detailed Review
SweetBun is a worldwide AI companion platform operated from the EU that goes further than chat: alongside text conversation it generates AI images and videos of a chosen character, and adds real-time voice calls and a real-time AI video feature the vendor calls "live webcam."
Its own terms of service state plainly that every character is entirely fictional and machine-generated, and that users are always communicating with software, never a person. It is not a Czech-only or Europe-only service: the interface and the AI conversation itself are available in 70 languages, which SweetBun sets against English-first rivals in its own comparisons.
What Makes SweetBun Stand Out
Voice and video are the differentiator. Most companion apps in this category offer chat plus static image generation; SweetBun adds real-time voice calls and AI-generated video on top, which is a meaningfully more complete live-interaction feature set than most of its European peers.
Features and Capabilities
SweetBun combines companion chat with AI image and video generation, real-time voice calls, and real-time AI video. Users can create their own custom AI characters, unlimited on Premium, and interact through text, voice or video depending on the plan.
Uncensored and NSFW Conversations
SweetBun supports open, mature conversation and generated content for users who want it. Its terms of service set explicit limits regardless of plan: no depiction of minors in any form, no sexual violence, and no deepfake content resembling a real, identifiable person.
All preset and generated characters are stated to be entirely fictional, with no model in any living person. Separately, its AI Real Clones programme builds consent-based AI twins of real creators, so not every character on the platform is without a real-life model.
Privacy and European Data Protection
SweetBun is operated by OneClick AI Solutions s.r.o., a registered Czech company based in Prague (company no. 23948353), which places it inside the EU with GDPR applying directly. That is the substantive difference from a US-based companion app: a companion transcript is a continuously generated, deeply personal record, and having an identifiable EU company responsible for it — rather than a US operator reachable only through the CLOUD Act — is a real jurisdictional difference, not a marketing claim.
The honest caveat sits one layer down, in the infrastructure rather than the company.
SweetBun's own privacy policy names Vercel, Supabase and Upstash as the providers behind hosting, database storage and related services, and states directly that these providers "may also be established outside the territory of the European Union" — which they are: Vercel and Upstash are US companies, Supabase is registered in Singapore.
No EU region is guaranteed for where data actually sits. The operating company is unambiguously Czech; the servers behind it are not committed to staying in the EU the way the company is.
Pricing
The free account is a limited freemium tier rather than a one-off trial: 5 chat messages per day, with the allowance reset daily, plus a free generation allowance on top. Premium is required for unlimited chat, monthly image/video tokens and call minutes.
Premium lists at $20/month, discounted to $16/month on a 3-month plan and $10/month on a 12-month plan, and includes unlimited chat, 100 monthly tokens for image/video generation, and 30 minutes of voice calls per month.
The terms of service state that refunds are granted within 24 hours of payment and only if usage stayed under a stated threshold; SweetBun told us it also grants refunds after that window in practice, so the written policy is stricter than the way the company says it operates.
SweetBun vs US Alternatives
Compared with Character.AI and Replika, SweetBun's case rests on the operating company being genuinely European and directly subject to GDPR, plus a broader live-interaction feature set (voice and real-time video) than most companion apps offer. The trade-off is the infrastructure caveat above: the company is Czech, but the hosting stack is not EU-committed.
Who Should Use SweetBun
SweetBun suits users who specifically want voice calls and real-time AI video alongside chat, and who are comfortable with an EU-established operator whose underlying hosting providers are not guaranteed to be EU-based. Users for whom EU-only infrastructure is a hard requirement, not just EU company establishment, should weigh that caveat before subscribing.
