See the sheet in action
Your investigator, from draft to dice.
A real browser walkthrough with a sample investigator: edit a draft, set a skill, make a hard check with a bonus die, and roll weapon damage. Silent video with on-screen captions.
Drafts stay in your browser. Export JSON for a backup. This recording shows the standalone guest sheet; chat-host installation and native result cards are not demonstrated.
Let the dice tell the story
Roll percentile checks with bonus or penalty dice, choose a difficulty, and roll weapon damage. Get clear results when the stakes rise.
Take your story with you
Export your investigator as JSON for a portable backup. Import it on another device, or attach it when you want help from your chat assistant.

A few things to know
Where is my investigator saved?
Drafts stay in this browser where local storage is supported. There is no cloud investigator library or automatic device sync. Clearing browser data can remove drafts, so export JSON to keep a backup.
Can my chat assistant see my sheet?
Only when you explicitly share it, such as by attaching your draft or exported JSON. Opening the sheet does not automatically let the assistant read your browser-local drafts. Proposed chat edits do not automatically change your sheet.
Can I share rolls with my group’s chat?
Optional private play sessions can send dice events to explicitly subscribed chats on hosts that support MCP Events. Sessions expire after 24 hours and retain up to 1,000 rolls. Keep the session token private: anyone holding it can access or end that session.
Does it create a complete, rules-ready character?
New drafts are editable starting points. Complete character creation with your Keeper and the game’s rules. Rolls do not automatically apply damage, spend luck, or change sheet resources.
The next clue is waiting.
Bring your investigator. We’ll bring the sheet.
