AI-GameFriend is a desktop app that connects LLM AI models (Claude, GPT, Grok, Gemini) to turn-based games as intelligent opponents. Unlike scripted game AI, it uses real reasoning every turn — meaning it can negotiate, bluff, adapt strategy, and surprise you.
You paste your own AI API key (from Anthropic, OpenAI, xAI, or Google). AI-GameFriend is the integration layer — it reads game state, sends it to your AI, and executes the AI's decisions. You control which AI you use and pay your own API costs directly.
It depends on the game length. A full Civilization game (300-500 turns) costs roughly $1.50-4.00 in API tokens. A chess match costs $0.05-0.15. XCOM missions cost $0.10-0.30. We show real-time cost tracking so you always know your spend.
MVP launches with Civilization V/VI. Within 3 weeks, we add Chess, Crusader Kings 3, and XCOM. By month 2, we support 8+ games including Total War, EU4, and board games via Tabletop Simulator.
Pure AI is the 6th personality preset — zero constraints, no role-playing, no personality flavor. The AI's only directive is 'win by any means necessary.' It serves as the hardest difficulty and the baseline benchmark for measuring all other personalities.
Arena mode lets you watch two AI models play against each other — Claude vs GPT, Grok vs Gemini. You spectate in real-time with AI thought bubbles and play-by-play commentary. It's available as a $5/mo add-on.
The Founder's Pass is a $199 one-time payment for lifetime access to all AI-GameFriend tiers (Pro + Arena + Creator). Only 500 available. Founders also get early access, a founder badge, and priority support forever.
