Starwright

You play. The AI runs the table. The engine owns the dice.

Starwright is a free AI Game Master for solo Ironsworn: Starforged play, right in your browser. The AI narrates the world, picks moves, and consults oracles — but every mechanical outcome resolves inside a deterministic rules engine the AI can't override. A miss is truly a miss.

Every roll renders as an inspectable card — dice, outcome, exactly what changed — and a GM log audits every tool call the model made. Nothing happens off-screen.

Highlights

• Full rules automation — oracles with nested tables, assets, impacts, legacy tracks, experience
• Character creation wizard — pick your truths, assign stats, choose starting assets (starship included)
• Bring your own model — any OpenAI-compatible endpoint (OpenRouter, local Ollama, …). Your API key never leaves your browser: no backend, no telemetry, no account
• Transparent by design — settlement cards, state diffs, and a full audit log of every GM tool call
• Save anywhere — sessions auto-save locally in your browser, with JSON export/import
• English / 中文 — bilingual UI with pre-translated game data; narration language is a separate setting

Cost

The tool is free and open source (MIT). You supply the brain — either your own LLM API key (you pay your provider for tokens) or a free local model via Ollama.
