Presenton

Presenton is an open-source AI presentation generator. It creates pixel-perfect slide decks from prompts, documents, or custom templates while preserving brand elements such as colors, typography, spacing, and layout.

The tool supports reusable designs derived from existing PPTX or PDF files through an AI template converter. It performs end-to-end deck generation that includes structure, storyline, layout, and content, with all slides inheriting the defined design system. Advanced editing capabilities cover slide variants, precise element selection, and targeted generation. Charts, tables, and images can be included when specified during template creation. Global theming allows consistent application of brand themes across presentations. Output occurs in PPTX and PDF formats, with PPTX files remaining fully editable in standard applications such as Microsoft PowerPoint and Google Slides.

It addresses needs for developers who embed generation via a clean API to produce and update decks from data and workflows. Teams gain access through a managed cloud collaborative browser UI or self-hosted deployment on local infrastructure. The same open-source engine runs across these options. Offline operation is possible with Ollama, and integration extends to various large language model providers and image generation models. Use cases include private local generation, automated compliant client reports in financial services, white-label embedding for SaaS products, and data-controlled enterprise workflows.

Presenton is delivered as a Docker container for quick self-hosting, with a cloud version available for managed use. It is provided under open-source licensing with no vendor lock-in. User data is not used to train models. The company behind it is Presenton Inc., located at 8 The Green, STE R, Dover, DE 19901, USA, and it complies with GDPR.
