Presenton is an open-source AI presentation generator that runs entirely on your local machine. Built as a powerful alternative to cloud-based tools like Gamma, Presenton offers you complete ownership of your data and full control over how presentations are generated.

With seamless support for multiple large language models (LLMs)—including OpenAI, Google Gemini, and Ollama—you can generate high-quality, customizable slide decks from simple prompts or uploaded documents. Export your output in PPTX or PDF format and, when using Ollama, enjoy GPU-accelerated, fully offline generation with open-source models.

Presenton is designed around three core principles:

  • Simplicity – No complex setup or vendor-specific tooling.

  • Flexibility – Choose your preferred LLM, define your own themes, and fine-tune the generation workflow.

  • Transparency – No telemetry, no vendor lock-in, and no hidden costs.

Whether you’re building technical presentations, summarizing reports, or creating educational materials, Presenton empowers you to work securely, efficiently, and on your own terms—with complete freedom over your infrastructure, APIs, and data.

Join the open-source movement and redefine how presentations are made—your slides, your way.
