As answered by people managing Rezup.ai and Diffee.
Rezup.ai's answer
Customers answer by voice instead of filling in a form. They scan a QR code or open a link, tap record and talk in their own language, with no app or account. Rezup transcribes and translates every answer into the owner's language, so a café in Lisbon can read what a Japanese tourist said. AI then groups answers into themes and flags the ones that need a reply.
Rezup.ai's answer
Form tools like Typeform or Google Forms get short answers and star ratings; people skip long forms. A 30-second voice message carries far more detail, and Rezup makes it readable: every answer is transcribed and translated automatically. Unlike video tools such as VideoAsk, customers don't need to show their face, and the owner reads text instead of watching clips. Data is hosted in the EU, responses are never used to train AI, and there is a free plan with 25 responses and 14 days of Growth features.
Rezup.ai's answer
Owners and managers of small and mid-sized businesses that serve customers in person: restaurants, cafés, hotels, clinics, salons and shops, especially those with international guests. Also online businesses such as course creators, SaaS and e-commerce teams that want real feedback and voice testimonials instead of survey scores.
Rezup.ai's answer
Rezup started with BlaBlaScribe AI, my transcription product. I wanted to know what to improve, but star ratings told me nothing: a "4 out of 5" never says what's wrong or what to fix. I needed users' own words, and typing a long answer is a chore most people skip. Talking for 30 seconds is easy. We already had speech recognition running on our own servers for BlaBlaScribe, so I built the simplest possible path: one question, a record button, and every answer arrives transcribed and translated into my language. It worked so well that it became its own product. Now Rezup does the same for any business that wants real feedback instead of ratings.
Rezup.ai's answer
Laravel (PHP), Vue.js with Inertia, MySQL, self-hosted WhisperX speech recognition on our own GPU servers, Google Gemini for translation and AI analysis, Stripe for payments, Brevo for email, hosted on Hetzner in the EU behind Cloudflare.
