Made for your campaign

A class worth
getting curious about.

ChatGPT creates the kit

Your classes and abilities are generated for the campaign, rather than chosen from a fixed catalog. The rules include a uniqueness gate: ChatGPT checks the proposed mechanics, practical uses and identity before offering them. It guides the model; it cannot guarantee originality every time.

A world to build from

The rulebook supplies the Age of Convergence lore and the game rules. ChatGPT builds your campaign's region, people and adventure from that setting. Five attributes including Luck, HP and MP, rarity rolls and earned upgrades give the homebrew system its own progression.

You can write your own

Type your own class or ability, revise an offer, or ask for a different setting, tone or way of playing. You can also change how ChatGPT writes and presents its responses. Agree on any rule changes with the GM before using them in the campaign.

Keep the adventure together

The story moves.
Your sheet stays close.

DnDGPT is a standalone 5e Hack with D&D-inspired d20 rules. ChatGPT handles the GM conversation; the connected service stores the campaign updates it saves.

Where your saves live

From Deon

Why I made this.

I thought ChatGPT's Intelligent UI was cool, and it gave me an idea: I could use the conversation for a fantasy RPG and keep the character sheet beside it.

I wanted to try unusual classes and abilities without digging through chat every time I forgot what one did. That's where DnDGPT started. ChatGPT handles the GM side, and the dashboard gives me somewhere to check my character and pick the campaign up later.
