## What it is Emergent is an AI-powered development platform (Y Combinator S24) that turns a natural-language description into a working full-stack web or mobile app. You describe what you want, its builder agent (E-1) works through it in a conversational loop, and for bigger projects an autonomous agent (E-3) plans, builds, tests and fixes across phases. ## Why I list it For quick prototypes and client demos it's a solid alternative in the AI-builder space — especially when a project needs a native mobile app alongside the web version, since it can build both from one repository. It handles coding, design, deployment and GitHub integration, so it's usable even with zero programming experience. ## What you can build Web apps, native Android and iOS apps, PWAs, dashboards, e-commerce sites, SaaS tools, internal business tools — from simple landing pages to multi-phase products with custom agents, a 1M context window and team workspaces on higher tiers.
