Best AI Copilots for Erlang

Replit is an AI app development platform that lets users describe an idea and turn it into a working project across web, mobile, design, slides, animation, data visualization, 3D games, documents, and spreadsheets. The platform is powered by Agent 4, an AI builder that can understand requirements, sequence work, write code, coordinate tasks, and publish production-ready apps. Infinite Canvas gives users a visual space to explore designs, make changes, and apply them directly to an app. Parallel Agents allow multiple tasks to run simultaneously with progress visibility before work is merged. Replit also supports multiple artifacts in one project, letting teams create apps, landing pages, videos, and related assets without switching context. Built-in full-stack infrastructure includes authentication, database, hosting, and monitoring with minimal setup. Integrations connect apps to AI models and services such as OpenAI, Stripe, Google Workspace, and more. Enterprise capabilities include SSO, SAML, SOC 2, admin controls, privacy controls, design system support, single-tenant environments, static outbound IPs, and VPC peering. By combining AI agents, collaborative development, visual design, production infrastructure, integrations, and enterprise controls, Replit helps users move from idea to deployed software faster.
