Real excerpt from a generated module for a party of 4, level 5.
THE HOOK
"A merchant guild has hired you to investigate a collapsed mine outside Thornwall. Three survey teams have vanished inside. The locals whisper of 'grey shapes that drain warmth and memory.' The guild is offering 800gp — more than enough to suggest they know something they're not telling you."
ENCOUNTER OVERVIEW
KEY NPCs
Mira Ashveil
Guild contact — knows more than she says
Cass the Hollow
The trapped ghost — tragic, not evil
"I had 45 minutes before my session and absolutely nothing prepared. Used OneShotly and ran the most memorable one-shot my group has ever played. The twist at the end had everyone at the table losing their minds."

"I was skeptical about AI-generated content. But this isn't a random module — it's actually balanced for my party's level and feels like it was written by someone who'd run hundreds of sessions. The NPC voice cues alone are worth the price."

"My Thursday group plays every week. I've bought six modules from OneShotly. Every single one hit differently. The map quality alone makes it worth it — I just drop it in Foundry and we're off."

Yes — and we're proud of it. Our system combines large language model generation with structure templates built from thousands of community-praised modules. The result isn't generic filler. It's playtested-quality content, delivered in seconds instead of hours.
Under 2 minutes. After checkout, our system generates your module and delivers the PDF directly to your email. If something goes wrong, we regenerate it free of charge.
Currently optimized for D&D 5th Edition. The encounter balance, CR math, and ability references are all 5e-native. Pathfinder 2e support is on the roadmap.
Simple. Email us within 7 days and we'll either regenerate your module or issue a full refund. No questions, no hoops. We'd rather you run a great session than keep $9.99.
Absolutely. The dungeon map is delivered as a detailed ASCII layout with room descriptions and connection notes — easy to recreate in Foundry VTT, Roll20, or any other platform. Token placement notes are included.
Your party is counting on you. Your module is 2 minutes away.
