D&D DM Tools

This tool provides a domain-focused workflow for dungeon masters to plan, design, and organize tabletop sessions. It models encounter difficulty using standard CR metrics, constructs NPCs with roles and motivations, and assembles treasure by rarity. Outputs are modular and exportable for campaign notebooks and handouts.

Core features are categorized as required or optional. Required features include: encounter generation by party level and environment with CR range; NPC and monster synthesis; loot generation; session notes; export/import. Optional/advanced features include: seed-controlled randomness for reproducibility; customizable creature pools and homebrew rule overrides; multi-environment tables; map prompts; and cross-campaign libraries.

Users are dungeon masters running published adventures or homebrew worlds, co-DMs in online groups, and organizers in casual campaigns. The tool accelerates prep, supports pacing, and provides repeatable outputs that can be quickly adapted on the fly.

A key strength is integrated, rule-aligned generation: outputs reflect CR tiers, experience point thresholds, and typical loot distributions. The system emphasizes usefulness and speed, delivering concrete outputs such as CR-balanced encounters, concise NPC briefs, and ready-to-export loot bundles for session prep.
