Four steps to your AI coach

No code. No complex setup. Just your methodology and your students.

Share your methodology

Define how your AI coach behaves. Set the personality, conversation flow, and coaching style. Add your methodology as a knowledge base.

Build your scenarios

Design practice sessions for different skills. Sales calls, feedback conversations, interview prep, whatever your students need to master.

Built for how trainers actually work

Everything you need to scale your coaching business.

Your method, their practice

Students practice with an AI coach that follows your methodology. Your approach, your conversation structure, your feedback style. Choose a professional voice or clone your own.

Any language, any time

Your AI coach speaks Dutch, English, German, French, and Spanish. Reach students anywhere without recording new content.

Track real progress

See every conversation, review transcripts, and measure improvement over time. Know exactly where your learners need help.
