What is Presenton?
Presenton is an open-source AI presentation generator and API released under the Apache 2.0 license. It creates presentations from a prompt, an uploaded document or your own PowerPoint design, and exports fully editable PPTX and PDF files. The README positions it as an alternative to hosted tools such as Gamma and Canva, with no SaaS lock-in and full control over models and data.
You can self-host the web version through a Docker package or download the desktop app for Mac, Windows and Linux. Desktop packages listed are a .dmg for macOS, a .exe for Windows x64 and a .deb for Linux x64.
Model choice is open: the README lists Ollama, LM Studio, OpenAI, Gemini, Vertex AI, Azure OpenAI, Amazon Bedrock, Fireworks, Together AI, Anthropic and any OpenAI compatible provider. Templates can be built with HTML and Tailwind CSS, or generated from an existing PowerPoint document. A generation API and a built-in MCP server let other applications and AI assistants create presentations programmatically.
