Plan-View Tabletop Quick Roller

Spawn and roll transient dice (d2 pass/fail coin, d4, d6, d8, d10, d12, d20, d100) right on top of the PDF. Designed with clean, top-down orthogonal silhouettes and draggable tokens to resolve quick checks, random tables, and traps without leaving the reading view.

Built-In PDF Outline & In-Context Search

Navigate sprawling sourcebooks using the collapsible document outline extracted straight from the PDF's native Table of Contents, backed by instant full-text search with contextual snippet previews.

100% Local-First & Portable Backup

The project is 100% private & client-side, so your annotations and PDFs never touch an external server - everything runs in your browser with zero account setup or cloud lock-in. Back up, share, and migrate entire campaign prep notes, highlights, and pins across devices using clean JSON export and merge-import tools.

Dungeondraft

English
Paid
Universal
Dungeondraft is a specialized, standalone map-making software designed specifically for creating high-quality TTRPG battlemaps. Developed by Megasploot (the creator of the world-building tool Wonderdraft), it was released in 2020 and has since become the industry favorite for GMs who want to build detailed, tactical maps without needing professional graphic design skills. It is famous for its "smart" tools that handle walls, lighting, and object scattering automatically, allowing a full encounter map to be completed in minutes. Description Dungeondraft bridges the gap between simple grid-sketching and complex image editors like Photoshop. It features a unique, hand-drawn aesthetic that fits perfectly with modern fantasy games. The software is built for efficiency; drawing a room automatically places floors and walls, and the integrated lighting engine allows you to place torches that cast realistic shadows in real-time. In 2026, it remains a "buy-once-own-forever" staple, free from the subscription models that have taken over much of the creative software market.
