Everything behind the DM screen, on one page
Free D&D 5e tools for running a game: roll dice, balance encounters, hand out loot and invent an NPC before the players notice you were improvising. Works on your phone, no account.

Built for the middle of a session
Most DM tools are made for prep day at a desk. These are made for the moment a player says "I pickpocket the guard" and everyone looks at you. Every generator works instantly in your browser, results land on a card you can read at a glance, and the combat tracker remembers the fight if your phone locks.
Rules numbers (experience points, encounter budgets, treasure tiers, point-buy costs) follow the free System Reference Document, so the maths matches the books at your table. Where the 2014 and 2024 rules differ, the encounter calculator lets you pick.
Where AI helps, and where it doesn't
Dice, encounter maths and stat arrays are pure arithmetic, so they run as plain code with a cryptographically random number source. Writing is different: a backstory, an NPC's voice, a tavern's read-aloud text. On those pages you can ask an AI writer to turn the random pieces into prose. It's optional, it only runs when you press the button, and the tools work fine without it.
