In their own words
Assembly
Assembly combines an AI app builder with a CRM and branded client experience for creating client-facing apps and internal tools. Users describe an app in plain language, review a proposed plan, publish it, and refine it in conversation. More than 30 templates cover workflows such as document collection, project tracking, proposals, and client support. Apps can connect to third-party services through authentication or an API key, and an MCP connector links the workspace to AI tools including ChatGPT and Claude. Workspaces include a branded client experience where published apps appear together. Assembly's platform handles client authentication, roles, permissions, and data scoping. The maker says it is SOC 2 Type II certified, stores customer data in the United States, encrypts it in transit with TLS and at rest with AES-256, and does not use workspace or client data to train AI models. It is not suited to public-facing websites, directories, or consumer apps. A free plan is available; Starter costs $29/mo billed annually.
