presenton
Presenton is an open-source application for generating presentations with AI, running locally on your own machine, and it presents itself as an alternative to Gamma, Beautiful AI and Decktopus. You can use your own API keys for OpenAI, Google Gemini, Anthropic Claude or any OpenAI-compatible endpoint, or run open-source models through Ollama, so you only pay your model provider and your data stays under your control.
Features in the README include custom templates and themes built with HTML and Tailwind CSS, AI template generation from an existing PowerPoint file so new decks follow your brand design, generation from prompts or uploaded documents, export to PPTX and PDF, an API, and a built-in MCP server for generating presentations over the Model Context Protocol. It runs with Docker, with configuration examples for OpenAI, Google, Ollama, Anthropic and compatible APIs, and there is a hosted Presenton Cloud and an enterprise contact. The source is Apache 2.0.
