Description

MarkItDown is an online converter inspired by Microsoft's open-source utility. It transforms various file formats—such as PDF, DOCX, PPTX, XLS/XLSX, HTML, CSV/TSV, EPUB, and IPYNB—into clean, structured Markdown. Built to optimize content for LLM prompts, RAG, search indexes, and Git workflows, it allows users to choose between secure browser-local processing or fast server-side conversion without requiring an account.

Lexica is an AI-powered image generation engine and platform. Using its proprietary Lexica Aperture model alongside Stable Diffusion models, it allows users to search, generate, and license photorealistic images for personal and commercial projects.
