# MyAdventures.AI > MyAdventures.AI is a solo tabletop RPG you play in your browser. An AI Game Master narrates the story and plays every NPC, a real rules engine rolls dice it can’t fudge, and everything the AI invents is recorded once and stays true forever. Key facts: solo tabletop RPG in the browser; the AI narrates while a real rules engine rolls all dice; two built-in systems (5e-Compatible built on the SRD 5.1, and Starpath, an original gritty sci-fi 2d20 system); players build and share their own rulesets, worlds and stories, with an AI co-author; free to start. ## Core pages - [How it works](https://myadventures.ai/how-it-works): the whole machine — the honest GM loop, rulesets/worlds/stories, combat, travel - [FAQ](https://myadventures.ai/faq): straight answers about playing solo, honest dice, building and sharing, pricing - [Pricing](https://myadventures.ai/pricing): free to start; plans and ink - [Discover](https://myadventures.ai/discover): community-built worlds and stories, ready to play or fork ## Browse - [Worlds](https://myadventures.ai/w): browsable settings, each with a public lore wiki - [Stories](https://myadventures.ai/s): campaigns with narrative arcs - [Game systems](https://myadventures.ai/r): 5e-Compatible (SRD 5.1), Starpath sci-fi, and community rulesets - [The Adventure Log](https://myadventures.ai/blog): devlogs and updates (RSS at /blog/rss.xml) ## Full text - [llms-full.txt](https://myadventures.ai/llms-full.txt): this index plus the full FAQ text
