Clay Good

Founding Engineer at OpenSpec

Hi! I’m Clay. I build useful software, explore hard problems, and write down what I learn.

Work

geoprims

Precise, cited math for drone mapping, surveying, aviation, and geodesy that runs on your device, even offline.

Web app · Geospatial
Sophie Well

Thousands of clinical calculators, drug references, and billing codes behind one search box. Free, private, and fast enough to use at the bedside.

Web app · Healthcare
Open Sim Lab

Practice the codes you cannot practice on patients. Full clinical simulations that run with no cost, no login, no install, and no network.

Web app · Clinical simulation
Rough Logic

Every calculation a trade needs, cited and correct, in a browser that still works when the job site has no signal.

Web app · Field tools
Enklayve

See what your paycheck, taxes, debt, and retirement actually look like without handing your finances to a single server.

Web app · Personal finance
Encrypt A Lotta

Encrypt, sign, hash, split a secret, scrub metadata. A full crypto toolkit that runs inside your tab and uploads nothing, ever.

Web app · Security
Vaulytica

Read a contract the way a linter reads code. Finds the clauses that cost you later and cites the exact line behind every one.

Web app · Legal contracts
Armorly

Your AI assistant should answer to you, not to advertisers. Strips ads and affiliate tracking out of ChatGPT, Grok, and Perplexity, and catches hidden prompt injection.

Chrome extension · AI privacy
Way of Kensei

A duel decided by reading your opponent, not by luck, grinding, or timers. Matches end in minutes.

iOS game · Strategy
Tokens

Compute is the commodity and the market is the board. Corner the AI stack before your opponent does.

iOS game · Strategy
Proxilion

Your AI agents already hold your SaaS credentials. Proxilion makes sure they can only do what a human actually scoped, and proves it on every single call.

Self-hosted proxy · AI security
Kyntic

The last line between a model and a machine that can hurt someone. Fails closed, in hardware, before an unsafe command ever reaches the actuator.

Hardware appliance · Robot safety
OpenLore

Your coding agent stops guessing. One call tells it exactly what a task touches, one gate tells it what it must not break. No API key, same answer every time.

Open source CLI · AI coding agents
Agent Replay

Your agent broke in production and the logs will not say why. Rewind the run, fork it at the exact step that went wrong, and prove the fix before you ship it.

Open source CLI · Agent debugging
Mantissa Stance

The cloud posture platform that normally costs six figures, rebuilt in the open. 300+ policies across AWS, GCP, and Azure in YAML you can actually read and change.

Open source platform · Cloud security
Mantissa Log

Ask your logs a question in plain English and get a real answer. A serverless SIEM that runs for a fraction of what the incumbents charge.

Open source SIEM · Security operations
Attestful

Audit season without the scramble. Pulls evidence from 30+ platforms, shows exactly which controls are still short, and exports OSCAL that any GRC tool can ingest.

Open source tool · Compliance
Qiuth

A leaked API key should not be game over. Qiuth turns bearer keys into proof-of-possession tokens that need more than the key itself to work.

Open source library · API security
Enklayve AI

A private AI that reads your documents on a laptop with the wifi switched off. Local models, encrypted at rest, free forever.

Desktop app · Local AI
Invariant

A signed safety boundary between an AI policy and anything that can move, dose, or open a valve. Refuses unsafe commands and leaves a verifiable audit trail even when the model itself is compromised.

Open source firewall · Physical AI safety
Veridex

Find out whether a robot dataset is safe to train on before it quietly wrecks your model. One command, any format, and a signed trust certificate you can hand to anyone.

Open source CLI · Robot data integrity
Anvilate

Describe a part and get the bending, buckling, resonance, and bolted-joint checks back with the code clause behind every number. No cloud, no account, no silent pass.

Open source tool · Mechanical design
