I create assistants, conversation partners and characters with a defined personality, memory and way of speaking, then test how they behave.

Character with purpose: Personal assistants, brand characters and expert digital twins. Consistent behavior: Role, tone, knowledge, memory and defined boundaries. Tested conversations: Sales practice or audience dialogue; voice and appearance when needed.

Private projects for the Brazilian market: personal assistants, conversation partners and characters with a sense of humor.

Starting from $400. One text persona in one language, with a defined character, simple persistent memory, a web interface and tested conversations.

I work remotely for the US, Canada and Brazil. We agree the system, scope, stages, timing and price before payment. External services are charged separately. Describe your task: https://services.denisostapenko.com
