Join the Early Access Beta

By Bitter Flame is actively in development. Expect rough edges, and please use the in-game bug report if something breaks.

Free trial — 20 turns included

Once your character is created, you get 20 AI turns on us. That's enough to explore a dungeon, fight a few encounters, and see how the GM plays.

Unlimited play with your own API key

After your free turns, bring your own Anthropic API key and play as much as you like. Keys are stored encrypted and never shared. A typical session costs a few cents.

Earn free turns for feedback

Find a bug or suggest a feature that gets added and earn bonus turns. Use the Submit a Bug and Suggest Feature links in the header once you're in.
