ArcQuill
AI Dungeon Master that actually remembers and plans ahead
ArcQuill launched on April 6, 2026.
What it does
ArcQuill is an AI-powered tabletop RPG where the DM doesn't forget your story. Every NPC, quest, and secret is tracked in a persistent world. The AI plans plot arcs before the game starts, filters what each NPC knows based on your relationship with them, and pulls relevant memories via semantic search so games can run hundreds of turns without losing the thread. Pick a world concept, get a character, and start playing in under a minute.
AI Dungeon Master with no context limits. Build your own worlds, share them with friends, and play with an AI that actually remembers.
Every NPC, every promise, every betrayal persists forever. The blacksmith recalls you stole from him. The guard recognizes your face. Actions have consequences that echo through time. Notes, characters, and world facts are selected into context automatically. You never manage what the AI knows. It just knows. The DM plans past the current scene: arcs, foreshadowing, and payoffs that land sessions later. Build your world and character through conversation before the first turn. Flexible tool calls let the DM roll dice, update quests, and edit the world, not just describe it. Upload a module, a novel, or your old notes. The World Bible fills itself from the pages.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
