# THL Open — AI-visibility engineering (GEO)

> The open layer of Tech Horizon Labs' GEO / AI-visibility practice: a Claude Code skill suite, two original tools, and the method that ties them together. GEO — Generative Engine Optimization — is how a business stays inside the answer when its customers ask ChatGPT, Claude, Perplexity, or Google's AI Overview instead of clicking a blue link.

## Start here

- [Are you found by AI? — free 60-second scan](https://areyoufoundbyai.com): the LIVE visibility measurement — asks ChatGPT, Claude, Perplexity and Google AI whether they actually name you, and who they name instead. This repo is the readiness diagnosis behind it. Hosted, no install.
- [The THL GEO Method](https://github.com/techhorizonlabs/thl-open/blob/main/docs/THL-GEO-METHOD.md): the three-layer workflow — dimensional audit, external benchmark, deliverable — and the scoring discipline that makes it repeatable.

## Tools (built by THL)

- [agent-readiness-scan](https://github.com/techhorizonlabs/thl-open/tree/main/skills/agent-readiness-scan): turns Cloudflare's isitagentready.com check into audit-grade artifacts — a fixed-schema CSV, a 0–100 score, and the evidence behind it.
- [audit-report-kit](https://github.com/techhorizonlabs/thl-open/tree/main/tools/audit-report-kit): turns an audit's JSON into a branded client PDF plus compile-checked JSON-LD, ready to paste.
- [GEO skill suite](https://github.com/techhorizonlabs/thl-open/tree/main/skills): citability scoring, AI-crawler access, llms.txt, schema markup, brand-mention scanning, platform-specific optimization, technical SEO, content E-E-A-T, and report generation.

## Method and evidence

- [Sources](https://github.com/techhorizonlabs/thl-open/blob/main/docs/SOURCES.md): the primary research the method is grounded in, and what it does not claim.
- [How THL Open compares](https://github.com/techhorizonlabs/thl-open/blob/main/docs/HOW-WE-COMPARE.md): an honest comparison with other GEO tools.
