New features
Sometimes you know exactly what should happen next. Other times, you want the AI to surprise you. Alchemy adds more ways to work with the AI in both moments, and a few reasons to come back tomorrow.

New feature
Use the Guide action to give the next response some direction. When a response is almost right, Guided Retry changes the one thing that’s off without leaving everything to another roll of the dice.

New feature
Turn on Narration in your Adventure’s Gameplay Settings to hear each response. Device voices are free, and Expressive and Max voices cost 1 and 2 credits, or are free for Mythic and Ultimate+ players respectively.

New feature
Turn a story moment or an uploaded image into a 5, 10, or 15-second video with H3 Turbo or H3 Max, directly within your Adventure.

New feature
Describe the cover, pick an image model and how many results you want, then click Generate, right inside an Adventure or Scenario.

New feature
Apply and combine Adventure Scripts in your own Adventures, no Scenario needed. Find one in the new Scripts section of Discover.

New feature
Unlock new profile images piece by piece, up to 3 pieces a day at 1, 10, and 25 turns. Voyage turns count double, and your progress never expires.

New feature
See your AI Dungeon history at a glance: when you played most, your total actions, how many Adventures you have, and more. Find it in your Saves or Profile.

New feature
Creators can now pin their favorite Scenarios to the top of their profile.

Still available for a while with the Show Deprecated Models toggle in Game Settings.
Superseded by better, more efficient options.
Deprecated for some time and now fully retired.
