What it solves

LandPPT is an AI-driven platform that automates the creation of professional presentation slides. It eliminates the manual effort of structuring content, searching for relevant imagery, and designing layouts by converting documents or simple topics into complete, ready-to-present slide decks.

How it works

The platform uses a multi-stage workflow—requirement confirmation, outline generation, content research, and final slide generation. It leverages Large Language Models (LLMs) to draft the structure and content, while integrating search engines like Tavily and SearXNG for real-time data gathering. For visuals, it blends local libraries, web searches (Pixabay, Unsplash), and AI image generators (DALL-E, SiliconFlow). The final output is rendered as an HTML presentation that can be exported to various formats.

Who it’s for

It is designed for anyone needing to produce high-quality presentations quickly, including students, educators, and business professionals, as well as developers looking to integrate AI-powered slide generation into their own workflows via API.
