## What is BioForge?

Build better AI prompts for training conversations.

BioForge helps you create structured prompts and instructions for ChatGPT, Claude, Gemini and Grok so your AI starts with the right context from the beginning.

Create a one-off Chat Prompt to start a new conversation or generate a persistent Project Instruction you can save inside supported AI platforms for future chats.

BioForge does not pretend to be the coach. It helps you create better setup instructions so your chosen AI responds in a more relevant and consistent role.
