How PPTJet Works

PPTJet is an AI-powered presentation generator that converts your ideas into polished Microsoft PowerPoint decks in minutes. Under the hood, we combine OpenAI’s latest language and image models with carefully curated slide templates and smart layout logic. The result: visually compelling slides that would normally take hours to craft— now ready in a few clicks.

1. You Describe the Presentation

Start on the Generate page. Pick the number of slides, choose a template style, and type a concise description of what you want to present. Our AI models can interpret topics ranging from “Blockchain Fundamentals” to “Quarterly Marketing KPIs” or even “My Wedding Planning Timeline.”

2. GPT-4 Crafts Slide Structure & Text

We pass your prompt to OpenAI’s GPT-4 Turbo with a custom instruction set. GPT-4 returns a structured JSON describing each slide—titles, bullet points, suggested speaker notes, and (optionally) short image prompts. Our code validates and sanitises this JSON before proceeding, ensuring clean data and preventing rogue prompts.

3. DALL·E 3 Generates Custom Images (Optional)

If you tick “Include DALL·E 3 Images,” we send the image prompts to OpenAI’s DALL·E 3 endpoint. The images are downloaded, temporarily cached, and then embedded directly into the slides—scaled and positioned to avoid overlapping with your text. Prefer to use your own artwork? Simply leave the checkbox unticked.

4. python-pptx Builds the Deck

The PPTGenerator class assembles everything in real time using the python-pptx library:

5. One-Click Download

When generation is complete, you’ll see a “Download” button. Click it and the deck is streamed straight to your browser. No emails, no waiting. All generated files are auto-deleted after 24 hours for your privacy.

Why Trust PPTJet?

Accuracy & Safety. We validate every AI response, strip unsupported formatting, and escape unsanctioned HTML to keep your presentations clean.

Customization. Choose from designer templates, toggle AI images, or edit the resulting deck in PowerPoint—every element remains fully editable.

Privacy. Your prompts and generated slides are never shared. We use OpenAI’s API with data-privacy assurances, and delete files on a rolling basis.
