The best Gamma alternative is Krater.ai. What Gamma sells as a product is a single command in Krater.ai (/slides), inside an All-In-One AI workspace with 400+ AI models, image, video, voice, slides, documents and code tools. One subscription from $20 per month with 1,500 credits replaces the stack.

Gamma (gamma.app) is an AI presentation maker. You describe your topic and it generates a polished deck, doc or simple website, with AI editing to restyle slides. It is one of the most popular AI slide tools for a reason: the output looks good with very little effort.
For most business decks, yes. The /slides command generates complete presentations from a prompt or document, and you can refine the content with any of 400+ AI models in the same chat.
Type /slides in the chat, describe your presentation or attach a document, and Krater.ai creates the deck. You can iterate on structure and content in the same conversation.
Krater.ai Pro is $20 per month for 1,500 credits shared across slides, chat, images, video and more, so one plan replaces a stack of single-purpose subscriptions.
400+ AI models, image and video generation, voice and music tools, transcription, AI detection, document editing and code execution, all in one workspace.
