Biosaï is a prompt engineering tool designed to deliver immediate value for predefined use cases. Users select a preset and answer a series of questions, which are used to generate a final prompt. This prompt is sent to an AI engine, which returns a tailored response.
joined the Biosaï team because I believed in its potential and was intrigued by the technologies involved. After contributing to the project in early 2023, I returned in 2024 to help further its development. As the main developer and one of three co-founders, I eventually transitioned away to focus on new freelance opportunities.
