Encounter Workbench

Build D&D 5e encounters, calculate encounter difficulty, and take a complete encounter sheet to the table. Encounter Workbench is an encounter builder and encounter calculator for Dungeon Masters using the revised 2024 rules in SRD 5.2.1.

Plan an original encounter in ChatGPT. Describe your party, setting, objective, and intended difficulty. Create a scene around real SRD monsters, with editable objectives, terrain, complications, and DM notes. Review the draft before saving.

Check the numbers as you prepare. Save party profiles, including mixed-level parties; select monsters and quantities; and compare total XP with Low, Moderate, and High party budgets. Inspect full monster stat blocks and source links.

Prefer to build encounters without AI? Use Manual mode in the workbench to choose the roster and write the scene yourself. Your connected website account keeps saved parties and encounters together across the website and ChatGPT.

Download encounters as PDF or Markdown sheets with your notes, monster statistics, encounter budgets, and SRD attribution. Reopen saved encounters, make copies, and recover encounters from trash.

An Encounter Workbench account is required for saved encounters and the ChatGPT connection. Supports SRD 5.2.1 monster content and revised 2024 encounter budgets only; it does not include paid-book monsters or the 2014 adjusted XP multiplier rules. Difficulty is an estimate, not a guarantee of balance or fight length.
