Prompt-engineered persona simulation — no RAG, no fine-tuning
Chat with your favorite tech educators — powered by AI
Persona AI simulates conversations with Hitesh Choudhary and Piyush Garg using pure prompt engineering — a curated persona profile plus your live session, styled by an LLM.
Responses are AI-generated simulations for educational purposes — not the real Hitesh Choudhary or Piyush Garg.
