Flagship project

TableArc

A local-first AI tabletop RPG engine built around canonical state, rules-aware procedure, persistent worlds, provider flexibility, and inspectable runtime behavior.

TableArc

The AI imagines. The engine remembers, adjudicates, maps, resolves, and proves.

TableArc is not simply a fantasy chatbot. It connects natural-language play to structured adventure state, character authority, maps, combat, rules, continuity, saves, and debugging.

How the work is approached

Make complexity legible.

The common thread across GreenKappa Labs projects is a preference for systems that are expressive on the surface and explicit underneath.

01

Clarify the real problem

Separate the user’s goal from the accumulated interface, process, or implementation noise.

02

Give each system an owner

Use clear contracts, structured state, and visible boundaries instead of hidden accidental behavior.

03

Prove the result

Validate the path that matters through real use, diagnostics, accessibility, and durable outputs.

Capabilities

From concept to working system.

GreenKappa Labs combines product thinking, engineering, design, documentation, and operational workflow experience rather than treating them as separate disciplines.

Applied AI software

Provider integrations, grounded generation, local models, structured outputs, and human-readable failure handling.

Interactive applications

Responsive interfaces, desktop packaging, stateful workflows, maps, dashboards, and user-facing diagnostics.

Workflow systems

Power Platform, SharePoint, Power Automate, operational tracking, forms, notifications, and process redesign.

Technical communication

Architecture plans, testing protocols, decision records, sourcebooks, presentations, and accessible reference material.

About the builder

Trevor Leininger

An independent software developer and applied-AI builder who works across product architecture, front-end systems, automation, technical writing, and creative technology.

TableArc is the clearest expression of that range: a long-running systems project combining React, Vite, Electron, OpenAI and Ollama providers, canonical state, rules-aware workflows, persistence, debugging, interface design, and public product communication.
