Top AI Product

Presenton is an open-source AI presentation generator positioned against Gamma, Beautiful.ai, and Decktopus. Apache 2.0 licensed, it gives you full control over the workflow: choose your models, keep your data private, run it locally.

## What sets it apart

Most AI slide tools are closed SaaS that lock your decks in their format. Presenton exports to PPTX (fully editable in PowerPoint and Google Slides) and PDF, ships as an Electron desktop app for Windows/macOS/Linux, and offers a one-command Docker deploy with GPU support for local models. Bring-your-own-model: it supports DALL-E 3 and gpt-image-1.5 (OpenAI), Gemini Flash and Nanobanana Pro (Google), Pexels, Pixabay, and self-hosted ComfyUI for images.

## The API angle

For developers, Presenton exposes an API to create and edit presentations programmatically — meaning an agent or backend service can generate decks on demand. That’s the piece Gamma doesn’t open up.

## Why it matters

AI slide generation has been a closed-SaaS category. An Apache-2.0 tool that runs locally, exports editable files, and offers a programmatic API flips the model — useful for privacy-sensitive orgs and for anyone wiring deck generation into an automated pipeline. The custom-model support means you’re not locked to one vendor’s image generator either.
