Directly with the studio’s founder in Nice — no account managers, no middlemen.
Yes. Every offer has a first step so you can judge the quality before a larger order.
By default, yes — the standard deployment runs on your own workstation, and your documents and data stay on your machine. Some capabilities (e.g. certain media or web-facing tools) may call external services when there's no practical local equivalent; when that happens, we tell you which service and why, before it's part of your setup.
We clone a voice only with the written consent of the person it belongs to. Without consent, the voice is not used.
One person reads this inbox — the same person who builds what you order.
Tell us what you have and what result you need — even a single small task. No brief required: within 48 hours you get a plan and a price in writing, a question, or an honest “not a fit”.
