About

I build tools for reviewing AI-generated work. I'm the maker of Promptiff, an open-source CLI and canvas that helps people compare their prompts with AI outputs and spot possible omissions or changes. I'm exploring better ways to work with AI agents.

Promptiff - Compare AI output against every prompt you gave it

Promptiff helps you review AI-written documents against the original instructions. Select one or more prompt turns and an output, inspect sentence-level matches, and find possible omissions or additions. Switch between semantic, word, Git-style, and character views. The open-source CLI, canvas, and Agent Skill run locally; remote embeddings are optional and require an explicit choice.
