scroll ↓

You roll a Nat 20 against the dragon. Your party erupts. Three weeks later, all you have left is a memory — and even that's getting blurry.

✦ Some moments are too legendary to forget. ✦

✦ Two paths, one app

Built for the whole table — DM or player.

One app, two ways in. DMs get the full Cockpit for prep, sessions, and AI co-DMing. Players get the Companion for character sheets, live updates, and a shared album. Cards happen automatically along the way.

Cards aren't a separate product — they're how moments become heirlooms. Captured in the Cockpit, sealed in the Album, displayed in the Hall of Fame.

✦ Based on a true story

Every card starts at a real table.

A line in the recap. A scene that wouldn't leave the group chat. EndoCraft turns it into something you can hold — sealed forever, one of one.

Free for DMs. No credit card. ~5 min setup.

✦ The loop

Prep. Play. Capture. Forever.

Four steps. Every session. Your campaign becomes a story you can hold.

01 · PREP

Build your world

Drop a PDF or write fresh. AI organizes locations, NPCs, scenarios — generates read-aloud text and statblocks for you.

02 · PLAY

Run the session

Live combat tracker. AI Co-DM in your ear. Players see live updates and roll on shared 3D dice.

03 · CAPTURE

Moments → Cards

AI pulls out the legendary moments from your recap. One click, sealed forever — rolled rarity, cinematic art.

04 · COLLECT

Album grows

Shared Party Album. 10 sessions = unlock an exclusive heirloom card. The legendary ones trend on the Hall of Fame.

🎲
REAL PHYSICS · LIVE SYNC
✦ When you roll, everyone sees it land

3D dice with real weight.

Your DM asks for a Wisdom Save DC 16. The dice tray appears on every screen. Five players, one moment, dice landing in sync. Nat 20s pulse gold. Nat 1s scratch crimson.

Cannon.js physics, custom resin theme, sound that lands. Not a gimmick — the moment that turns your session into a card.

✦ RARITY — ROLLED BY A D20, NEVER BOUGHT
Misprint
NAT 1 · 3%
Common
2–6 · 17%
Rare
7–13 · 35%
Epic
14–19 · 37%
Legendary
NAT 20 · 8%

Legendary can't be bought — every rarity gets rolled server-side the moment you submit. No retries, no tricks.

Misprint is the wild card. A Nat 1 doesn't mean failure — your card still gets its full art. But the frame gets wrapped in CSS glitches: scanlines, RGB splits, inverted text. Rarer than Legendary. Uglier. Strangely coveted — because you can't reroll for one.

✦ What makes EndoCraft different

Not another character builder.

There are dozens of D&D tools. EndoCraft is the only one that turns the moments at your table into something permanent.

🤖

AI Co-DM that knows your campaign

Reads your locations, NPCs, recaps. Suggests rules, lore, and improv moves in real-time. Never overrides — always there.

⚔️

Combat that runs itself

Initiative, HP-bars, conditions, multi-attack rolls. AI Encounter Builder generates balanced fights with full statblocks. Click an ability, players roll.

🃏

Moments → Cards, automatically

The AI watches your sessions. Pulls out the legendary moments. Rolls rarity server-side. Generates cinematic art. Sealed forever.

✦ FAQ

Still have questions?

What exactly is EndoCraft — and who is it for?
EndoCraft is a D&D session platform for the whole table. DMs get a full campaign cockpit: prep tools, an AI Co-DM, live combat tracker, and automated session cards. Players get a companion app with their character sheet, live updates, and a shared party album. It works entirely in the browser — no install needed. Designed for 5e but adaptable to any TTRPG.
Do I need to install anything? Does my group need to sign up?
Nothing to install — EndoCraft runs entirely in your browser. The Session Scroll tool doesn't require any account at all: paste your recap, get your card. For the full Cockpit, DMs create a free account. Players join via a magic link the DM sends — no signup, no password. One tap and they're in during the session.
How does rarity work — can I buy a Legendary card?
No. Rarity is determined by a D20 roll on our server the moment you submit — Common (2–6), Rare (7–13), Epic (14–19), Legendary (Nat 20, 8%), and Misprint (Nat 1, 3%). You can re-roll a moment for €0.50 with a different art style, but the rarity is always re-rolled. No amount of money guarantees you a Legendary. That's the point.
When are Living Cards and Campaign Memory coming?
Both are in active development. Living Cards (animated, glowing card art) and Campaign Memory (recurring NPCs, plot threads across sessions) are the next major features. Check the Roadmap for current status, or join the waitlist below to be notified the moment they drop. Patreon supporters get beta access first.
