Tools

Small tools I built while writing about prompting, econometrics and data. They run entirely in your browser.

AI image prompts

Visual Prompt Builder

Build prompts for Midjourney, DALL-E and Stable Diffusion by clicking through hundreds of example styles, artists, formats and vibes.

Econometrics

Linear regression with R squared, p-values, adstock and diminishing returns, and point-and-click variable selection, without Excel.

Data anonymization

Anonymize sensitive data for courses, blog posts or product demos without losing the patterns in it. Your file never leaves your browser.
