Brew a new card

One sentence is enough. Everything else is seasoning. Describe what you need — "a cursed blade that whispers the names of its former owners" — pick a system and a tone, and the cauldron returns a finished card laid out as that system's real sheet, ready to print and play.

What you can brew

• NPCs — a face with a voice, a secret and a hook
• Monsters — a stat block with traits, actions and tactics
• Magic items — properties, lore and a story worth handing over
• Spells — range, components, effect and scaling
• One-page adventures — hook, villain, keyed locations and climax on one page

Supported systems

Each system gets its own sheet and its own rules vocabulary, not a reskin of the same block.

• D&D 5e — real stat blocks, DCs, CR and rarity tiers
• Pathfinder 2e — PF2e traits, the three-action economy and levels
• Call of Cthulhu — 7e characteristics, skills and Sanity
• Generic — system-neutral text that drops into any ruleset

What it costs

Nothing. A free account brews free every day: 10 cards a day on the free models, with no payment card. It also lets you keep cards private and rename them. Cards brewed in public join the open library, free for anyone to use and remix.
