What is SessionWeaver?
SessionWeaver is AI-powered D&D 5e session prep that generates complete session plans with NPCs, encounters, locations, and plot hooks in minutes.
SessionWeaver generates complete D&D 5e session plans in minutes. You write a recap of what happened last time, and the AI builds your next session around it — complete with NPCs, encounters, locations, plot hooks, and more.
The kind of prep that used to take two to four hours now takes 15 to 30 minutes. And because SessionWeaver remembers your campaign across sessions, the content it generates actually fits your story.
What you get
Every generated session contains eight structured sections:
| Section | What it is |
|---|---|
| Strong Start | A dramatic opening scene that hooks your players from the first sentence |
| Scenes | Key story moments with branching outcomes your players might trigger |
| NPCs | Characters with personality, motivation, appearance, and speaking style |
| Locations | Atmospheric places with sensory details your players can explore |
| Encounters | Combat scenarios balanced to your party's level |
| Secrets & Clues | Hidden information with multiple ways players can discover it |
| Complications | Unexpected twists ready to deploy mid-session |
| Rewards | Level-appropriate loot, story rewards, and new allies |
SessionWeaver generates the framework. You edit, rearrange, and make it yours before game night. Think of it as a first draft from someone who knows your campaign.
Campaign memory
This is what makes SessionWeaver more than a one-shot generator. Every NPC your party meets, every location they visit, every plot thread left dangling — it all gets tracked in your Entity Library.
When you generate a new session, the AI draws on that memory. Kella the spice merchant does not just vanish after session three. The cult your players exposed keeps scheming. The tavern they burned down stays burned.
The more sessions you run through SessionWeaver, the richer the generated content becomes. Your campaign develops its own history, and the AI respects it.
