# Projects > Experiments, side projects, and things built to be useful. 14 projects by Will Feldman, newest first. "Pre-ChatGPT" marks work made before ChatGPT launched on Nov. 30, 2022. ## MINDPRINT Made: Oct. 2026 · Tags: Artificial Intelligence, Markdown, Open source A proposed open standard for carrying a person's perspective into AI: one reviewed MINDPRINT.md file describing how they decide, communicate, and review work. MCP connects tools and Agent Skills package capabilities. MINDPRINT carries perspective: a plain Markdown file describing how a person decides, communicates and reviews work, created with AI from examples they choose to share or a guided interview. The author reviews the patterns and removes private details before sharing the file. A coworker can then ask their own AI to review a plan through that perspective. The file gives the AI a lens; it does not speak for its author. The repository publishes a v0.1 draft specification, a builder skill, a privacy review, reference tools and synthetic examples under the MIT license.

Supper scans grocery receipts into a pantry, suggests recipes from what is already in the kitchen, and answers follow-up questions while you cook, with a Live Activity for the recipe in progress. It is a native SwiftUI app with private iCloud sync, a Vercel API that verifies App Store purchases and tracks usage allowances, and AI features that only run after explicit consent. It is available on the App Store.

Atlas teaches countries through three connected clues: the flag, the capital and the location on a world map. Each region is a unit on a world tour that ends with a passport stamp, and Trunk, a suitcase mascot, cheers along the way. Missed answers come back in spaced review, questions get harder with look-alike flags and nearby capitals, and every country and capital is read aloud with recorded voices. Progress syncs through iCloud, with a guest mode so someone else can practice on your phone.

ReadU was built for the TED AI For Good Hackathon to improve the reading comprehension of middle school students. A baseline reading measures each student's level, then ReadU writes passages that match both their skill and their interests. As students work, it adjusts the difficulty of the text and focuses questions on the skills that need practice. ReadU was a finalist in the hackathon.
