Presenton: The Open-Source AI Presentation Tool That Keeps Your Data Your Own (No Cloud, No Compromise)

amy 09/12/2025

What is Presenton?

Presenton is not just another AI slide generator, but a privacy-first, self-hosted powerhouse built for creators, builders, and thinkers who value control, clarity, and freedom.

Why You should Try it Out?

While tools like Gamma, Beautiful AI, and Decktopus promise speed and style, they come with a catch: your data goes into the cloud. And once it’s out, you’re at the mercy of their policies, tracking, and potential leaks.

Presenton flips the script:

  • All processing runs locally: on your machine. No internet? No problem.
  • Zero data leakage: your pitch decks, research, and sensitive content stay private.
  • Open-source & transparent: you can audit, modify, or contribute. No black boxes.
  • Supports your favorite models: use OpenAI, Google Gemini, Anthropic Claude, or run open-source models like Llama 3 via Ollama, all under your control.

Who Is This For?

  • Freelancers who want to deliver branded decks without exposing client data.
  • Founders & investors building pitch decks with sensitive IP.
  • Educators & therapists (like Dr. Hamza Musa, who values ethical, mindful systems) who need secure, customizable tools for sharing healing frameworks.
  • Developers tired of vendor lock-in and eager to own their workflow.
  • Teams wanting to deploy their own private AI presentation engine.

Use-cases

Here’s where Presenton stops being “just another tool” and starts becoming indispensable:

1- Turn any PPTX into a design template

Upload your existing presentation, whether it’s a brand deck or a personal project, and let Presenton extract its style. Then generate new slides that look exactly like your original. Consistency? Done.

2- AI that actually listens

Tell it what tone to use, casual, professional, educational, even funny, and it adapts. Want a concise summary or a deep-dive? Adjust verbosity. Need web-searched insights? Enable it.

3- Export in PPTX or PDF, no compromises

Perfect formatting. Clean layouts. Ready to present, today.

4- Full API access

Build custom workflows. Automate reports. Integrate with your internal tools. Presenton’s API lets you generate presentations from CSVs, databases, or even live data streams.

Built for Real Workflows (Not Just Hype)

You don’t need to be a dev to use it. But if you are, you’ll love:

  • Docker support (even GPU-accelerated via Ollama)
  • Custom HTML/Tailwind themes
  • Multi-provider image generation (DALL-E 3, Gemini Flash, Pexels, Pixabay)
  • Web grounding for up-to-date facts
  • Full environment variable control (lock down keys, disable telemetry)

And yes. it’s free. Under the Apache 2.0 license. No paywalls. No subscriptions.

Ready to Try It?

It takes less than 5 minutes to get started:

docker run -it --name presenton -p 5000:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

Then visit http://localhost:5000 , and start generating.

Final Thought

In a world where AI tools sell your creativity for profit, Presenton reminds us: you should own your ideas, and your data.

No cloud bloat. No hidden fees. No compromise.

Just powerful, privacy-respecting AI presentation creation, made by humans, for humans.

👉 Try Presenton today. And never share your next big idea with a stranger again.

Star it on GitHub. Share it with a fellow builder. Because the future of AI tools shouldn’t be locked behind a firewall, it should be yours.
