About

Who's behind this

Applesauce is built by William Wyatt — PhD economist and AI researcher at Claremont Graduate University, with a background in physics and mathematics.

14 years of Python and C++. Published research on how LLMs reason, decide, and take risks. 136+ open-source repos. Everything from computer vision tools to market simulation engines.

Now channeling all of that into shipping products that solve real problems — fast, AI-native, and built to work on day one.

What we've built

Sell

Live

The fastest way to turn a photo into a listing. Snap a picture of anything you want to sell, and Sell identifies it, writes the title and description, pulls real-time eBay sold comps, estimates shipping costs via Pirate Ship, and gives you a data-backed price — all in seconds.

Built for resellers who source at thrift stores, estate sales, and garage sales. Source Mode gives you a quick buy/pass signal right at the shelf — no need to research on your phone. Once you're ready to list, post directly to eBay and Facebook Marketplace without leaving the app.

Three Body

Live

An interactive gravitational simulator that models the classic three-body problem — one of the most famous unsolved problems in physics. Three celestial bodies orbit each other in real time, creating chaotic, unpredictable trajectories that never repeat.

Customize each particle's mass and velocity, switch between torus and plane boundary conditions, toggle between eat and bounce collision modes, and follow individual bodies as they trace paths through space. A playground for chaos theory, orbital mechanics, and just watching things crash into each other.

Tome

Live

A collectible card game where every card starts as a photo. Take a picture of anything — your cat, a sunset, a weird rock — and Tome turns it into a playable card with stats, an element, and a rarity tier. Then battle other players' cards in Card Clash.

Each card gets assigned one of eight elements (Fire, Water, Earth, Air, Light, Shadow, Electric, Nature) and a rarity from Common to Mythic. Cards have attack, defense, and speed stats generated from the image itself. Collect cards, fuse duplicates to power them up, and climb the leaderboard.

Graze

Live

Know what's in your products. Point your camera at any food, cosmetics, supplement, or baby care label and get an instant safety report. Graze reads every ingredient, cross-references it against databases of 56 flagged food additives, 82 cosmetic ingredients of concern, and 50+ allergen keywords, then gives you a clear safety score out of 100.

Set up a personal allergen profile and get highlighted matches in every scan. No more squinting at labels or Googling ingredients one by one — Graze uses GPT vision to extract text from the messiest labels and maps each ingredient against Open Food Facts and curated safety databases.

136+ repos

Everything we build rests on a foundation of open-source work spanning 14 years. Computer vision pipelines, blockchain IoT systems, behavioral game theory experiments, market simulation engines, causal inference toolkits, and more — all public on GitHub.

Research areas include LLM behavioral alignment (how AI models reason about risk and make decisions), econometric modeling, and applied machine learning. Published work from Claremont Graduate University covers game theory, AI decision-making under uncertainty, and zero-bail policy analysis.
