Summary
PromptBuild.ai is a new tool designed to bring version control, testing, and performance analytics to large language model (LLM) prompt engineering, addressing common issues like tracking prompt variations and team collaboration. By offering features such as visual version timelines, interactive testing, and performance scoring, it streamlines prompt management and experimentation. This solution could significantly improve workflow efficiency and reproducibility for AI teams working with LLMs.
Hey everyone! After months of managing prompts in spreadsheets and losing track of which variations performed best, I decided to build a proper solution. PromptBuild.ai is essentially GitHub meets prompt engineering - version control, testing, and performance analytics all in one place. The problem I was solving: - Testing 10+ variations of a prompt and forgetting which performed best - No systematic way to track prompt performance over time - Collaborating with team members was chaos (email threads, Slack messages, conflicting versions) - Different prompts for dev/staging/prod environments living in random places Key features built specifically for prompt engineering: - Visual version timeline - See every iteration of your prompts with who changed what and why - Interactive testing playground - Test prompts with variable substitution and capture responses - Performance scoring - Rate each test run (1-5 stars) and build a performance history - Variable templates - Create reusable promp
