What it is
Presenton runs as a small web application inside a container and turns a text prompt or an uploaded file into a presentation. It also ships desktop builds for macOS, Windows and Linux for people who would rather not touch a command line.
What it is good for. Anyone who makes the same shape of deck over and over — a weekly report, a course module, a client summary — and pays a per-seat subscription to a hosted deck generator for the privilege. The output is a real PPTX file rather than a locked page, so it opens in PowerPoint, Keynote or LibreOffice and can be finished by hand. The same generation path is exposed as a single web address, /api/v1/ppt/presentation/generate, so it can be wired into an existing pipeline instead of being clicked.
- Plain Apache 2.0 with nothing added. In a category full of restrictive terms, this one has none.
- Genuinely free in its choice of model. OpenAI, Anthropic, Google, Azure, Bedrock, OpenRouter and several others are supported, and so are Ollama and LM Studio, which run a model on your own hardware with no bill and no data leaving the machine.
- The output is an editable PPTX and the interface is one documented endpoint, so it fits into work you already do rather than replacing it.
- Every release is a beta. The whole published history is 0.9.x-beta and there is no 1.0. There is no stable version to pin to.
- No resource figures are published anywhere. The README, the documentation site and the hosting page give no memory, disk or graphics-card numbers. If you take the local-model route, the model download is the dominant cost and its size is not documented at all.
- The setup is a command line, a container, a mounted folder and an API key held as an environment variable. That is a real barrier for someone who does not use a terminal, and the desktop build is the only way around it. Everything lives in the mounted
app_datafolder, so losing that folder loses every deck.
