What it solves

LandPPT is an AI-powered platform that automates the entire process of creating professional presentations. It eliminates the manual effort of drafting outlines, designing layouts, finding relevant images, and writing speaker notes, transforming a simple topic or a document into a complete, editable presentation.

How it works

The platform uses a structured AI workflow:

1. Input: Users provide a topic description or upload documents (PDF, Word, Markdown, Excel, PPT).
2. Planning: The AI generates an editable outline, which can be enhanced with real-time web research using Tavily or SearXNG.
3. Generation: The system produces HTML-based slides with AI-adaptive layouts and templates.
4. Refinement: Users can edit content and styles via an AI chat sidebar and swap images using integrated image services.
5. Delivery: The final product can be exported to various formats (PDF, HTML, PPTX, DOCX, Markdown) or shared as a public link with accompanying audio narration.

Who it’s for

It is designed for anyone needing to create high-quality presentations quickly, from students and educators to business professionals, as well as developers who want to integrate PPT generation via a REST API.
