Campaign Keeper — your Game Master's right hand

You love running the game. You don't love spending four hours prepping for three hours of play, or forgetting what that innkeeper promised your players two months ago.

Campaign Keeper is a Skill for Claude (Anthropic's AI) that remembers your whole campaign and preps your next session in minutes.

- Not a template you fill in: it writes the prep for you.

- No install, no API key, no setup: it runs inside the Claude plan you already have.

WHAT IT DOES

🧠 Remembers everything

Player characters, NPCs, open threads, promises, villain clocks and an in-game calendar, kept between sessions.

🗺 Preps your next session

- A strong opening that starts in the middle of the action

- 3–4 open situations (no railroads), each saying what happens if the players ignore it

- Key clues reachable in 3 different places, so the story never gets stuck

- Memorable NPCs with a goal, a voice and a secret

- Encounters with terrain, a twist, a retreat point and difficulty dials

- An improv kit and a one-page sheet for behind the screen

📝 Debriefs after play

Tell it what happened, even messily. It updates the campaign, advances the threats, and writes a spoiler-free "Previously on…" recap for your players' Discord or group chat.

🎭 Tracks the spotlight

It notices which player hasn't had a moment lately and builds a scene around them.

⚡ At the table

"I need a name for this guard, now." Three lines that fit your world.

HOW IT COMPARES

Most campaign tools give you a place to store notes: you still write everything yourself. Campaign Keeper does the writing. You tell it what happened; it gives you back an updated campaign and a session ready to run.

📁 Obsidian user? In Claude Code your campaign is saved as plain Markdown files (codex, party, NPCs, threads, sessions): open them in Obsidian or any editor. Your campaign stays yours.

WHAT YOU GET

- campaign-keeper.zip: the Skill, ready to upload to Claude

- Quick Start PDF: install in 2 minutes, starter prompts, tips, troubleshooting

REQUIREMENTS

- A Claude account (claude.ai) with Skills enabled. A paid Claude plan is recommended for long session preps.

- Works in the Claude app (web/desktop) and in Claude Code.

- In the Claude app the campaign travels between chats as a compact CAMPAIGN SNAPSHOT you save in a Project. In Claude Code it is saved automatically as files.

SYSTEMS

5e-compatible (SRD content only), Pathfinder 2e and any other tabletop RPG. Answers in your language: English, Italian, Spanish, German…

WHAT IT WON'T DO

- Copy text from published adventures or rulebooks: it works from your notes and open rules.

- Decide your story: it suggests, you decide.

- Guarantee perfect balance: encounter difficulty is an estimate, with dials to adjust at the table.
