Frequently Asked Questions

SweetBun is operated by OneClick AI Solutions s.r.o., a registered company based in Prague, Czech Republic, and GDPR applies directly to it. The caveat: its own privacy policy names Vercel, Supabase and Upstash as processors for hosting and database services, and states these "may also be established outside the territory of the European Union" — which they are (US and Singapore). The company is EU-established; the infrastructure behind it is not guaranteed to stay in the EU.

SweetBun is based in Prague, Czech Republic, and is operated by the registered Czech company OneClick AI Solutions s.r.o. (company no. 23948353). We highlight European AI companion services because they keep the operating company — and the legal responsibility that comes with it — inside EU jurisdiction.

Yes, within limits stated in its terms: no depiction of minors in any form, no sexual violence, and no deepfake content resembling a real, identifiable person. All characters are stated to be entirely fictional and AI-generated.

The free account gives 5 chat messages and 1 generated image as a trial, not an ongoing free tier. Premium is $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 generation tokens and 30 minutes of voice calls per month.

Yes. Premium includes real-time voice calls (30 minutes/month) and a real-time AI video feature, alongside chat and AI image/video generation — a more complete live-interaction set than most apps in this category, which typically stop at chat and static images.

SweetBun is a European alternative to US-based apps like Character.AI and Replika, with voice and real-time video added on top of chat and image generation.
