Session Forge — Offline Adventure Studio

Prepare your next tabletop RPG location offline.

Try it free first: Download the free preview to generate a 5-room location and export a player SVG map. Unzip it and open "index.html" in a desktop browser.

Continue your prep with the full edition ($19 USD or more): save an editable project as JSON and reopen it later, then export a separate GM map (SVG) and GM room notes (Markdown). Save your JSON file before regenerating or closing the app; there is no cloud sync or automatic backup.

Session Forge helps Game Masters generate schematic room maps, edit adventure notes, and export separate GM and player maps.

FEATURES

• Fantasy, sci-fi, and mystery prompts.

• Seed-based layouts with 5–12 rooms.

• Separate GM and player SVG maps. Secret rooms and designated secret connections are hidden from player exports.

• No account, subscription, or API key required.

• Commercial use of generated notes and maps under the included license.
