Spindrel helps you run the campaign you already built.
Your world lives in session notes, NPC briefs, and a folder of lore that got away from you around session 12. Spindrel reads what you wrote, tracks what stays alive across sessions, and hands you one printed page to run tonight from.
Bring in your notes
Paste session recaps, NPC briefs, faction write-ups, whatever you have. Spindrel pulls out the people, places, factions, items, and open threads it finds there, with receipts: every entry cites the line it came from.
Confirm what's real
You review the roster. Keep, drop, merge, rename. Mark who's active in the current arc and who's off-screen for now. You stay the author of record; Spindrel just keeps the ledger straight.
Run from one page
Before game night, Spindrel assembles a one-page brief from your own material: a strong start, the threads in motion, the NPCs worth having ready, and the secrets still in your pocket. Print it, run from it, leave the laptop closed.
No generated content. Ever.
Spindrel uses retrieval to help you find and connect what you have already written. It does not generate NPCs, lore, backstories, encounters, or art. It does not train on your data. We believe the GM is the author, and the tool's job is to serve the author's memory, not replace the author's creativity. We will not add generative features. This is a permanent commitment, not a launch-day promise.
Your data survives us
Everything you put in exports back out: Markdown, plain text, and a printable PDF. Open formats, no lock-in. If Spindrel ever shuts down, your campaign walks away intact.
