A simple web-based markdown editor that allows users to write and preview markdown content in real-time. It supports common markdown syntax and provides a clean interface for note-taking, documentation, or blogging. Built with React, TypeScript, and Vite, it features live split-view preview, syntax-highlighted code blocks (highlight.js), math/LaTeX rendering (KaTeX), tables, task lists, strikethrough, footnotes, and 40+ emoji shortcuts. The editor includes line numbers, find & replace with regex, undo/redo history, auto-complete snippets, keyboard shortcuts, and drag & drop image support. Productivity tools include localStorage persistence, multiple document tabs, auto-save versioning, export to HTML/PDF, shareable compressed URL links, and clipboard copy.

Erase-a-Scene is a web-based background removal tool built with React, TypeScript, and Tailwind CSS. Users can upload an image (via file upload, URL, or clipboard paste) and the tool leverages the Remove.bg AI API to automatically isolate the subject — people, objects, pets, etc. — and strip the background. Results are shown through an interactive before/after comparison slider. Users can replace the background with a custom color or keep it transparent, choose a download format (PNG, WebP, JPG), rename the output file, and share or copy the result to clipboard. The app also includes dark mode, processing history with localStorage persistence, and keyboard shortcuts for a streamlined workflow. It's ideal for creating profile pictures, product photos, social media graphics, or any use case where you need a clean subject cutout.
