Open-source AI tools for browser workflows, source-grounded research, and practical operator software.

Builder profile • Start here • Full atlas • Technical shape

This organization is the public showcase for software that should make sense from the outside. The goal is simple: when someone lands here, they should be able to tell what each repo helps a user do, where to start, and why the product is worth a closer look. It is a portfolio, not a dumping ground.

Built by Terry Yu.

The repositories in this org are organized around five connected product lines:

If this is your first visit, these six repos are the fastest way to understand the shape of the portfolio:

Across this org, the public repos should make three things easy to find:

• the fastest honest first result
• the docs page that gets a new visitor moving
• the boundary between what is already public-proof and what still needs local setup or maintainer-only steps

All 13 public repositories, with no hiding:

• CortexPilot-public Governed AI task orchestration for running work, reviewing evidence, and replaying failures without guesswork.
• ui-automation-control-plane Browser automation control plane for running flows, reviewing proof, and shipping with governed quality gates.

• prooftrail Run workflows through one canonical path and inspect the evidence bundle afterward.
• multi-ai-sidepanel Compare major AI tools side by side in one browser extension.
• campus-copilot Organize academic workflows from multiple platforms in one local-first product.

• sourceharbor Pull source streams into digests, job traces, and searchable artifacts.
• provenote Import one source, search it, and export auditable markdown you can inspect later.
• docsiphon Convert docsites into local corpora that agents and operators can actually reuse.

• openui-mcp-studio Turn UI briefs into React and shadcn files you can preview and verify.
• dealwatch Track grocery prices across stores with compare views, watch tasks, and alert history.

• apple-notes-snapshot Back up Apple Notes with visible health checks and structured exports.
• apple-notes-forensics Recover Apple Notes data with a copy-first, reviewable toolkit.
• movi-organizer Organize media with manifest-driven workflows and reviewable automation.

This org is not just a collection of prompt wrappers. The stronger repositories here repeatedly combine:

• Python / FastAPI control planes and orchestration backends
• Next.js, React, and TypeScript product surfaces
• Playwright-based browser execution and proof paths
• MCP interfaces so the same systems can be used by both humans and agents
• evidence bundles, manifests, diagnostics, and replay-oriented artifacts
• hosted-first public CI with explicit boundaries for sensitive or live paths

• Local-first when it improves trust, ownership, and recovery
• Evidence-first when systems make claims about what happened
• Operator-visible instead of demo-only
• Hosted-first public CI with explicit gates for sensitive lanes
• Real workflows over decorative prototypes

• If you want the flagship systems first: start with CortexPilot-public and ui-automation-control-plane
• If you care about proof, repeatability, and browser evidence: start with prooftrail
• If you care about source-grounded research: start with sourceharbor, provenote, and docsiphon
• If you want product-facing AI UX: start with openui-mcp-studio, multi-ai-sidepanel, and campus-copilot
• If you want local-first recovery and utility tools: start with apple-notes-snapshot, apple-notes-forensics, movi-organizer, and dealwatch
