Visit Assembly

Assembly is an AI app builder for professional services firms that turns plain-language descriptions into working client-facing apps and internal tools. Users describe an app, review and approve a plan, and publish it into a workspace where hosting, authentication, permissions, payments, and notifications are handled by the platform. Apps can be refined after launch through continued conversation.

The platform includes an integrated CRM, a branded client experience on the firm's own domain, roles and permissions, notifications, workflows, ready-made apps, an API & MCP connector, and integrated payments. Client accounts support magic links, Google, passwords, and MFA, with each app running in its own sandboxed environment and database. Templates are available to start from, and apps can connect to third-party services via API keys. The platform is SOC 2 Type II certified, with HIPAA support available on the Advanced plan.

Assembly is packaged as a free forever plan alongside Starter, Professional, Advanced, and Enterprise tiers, with monthly or annual billing. Plans are limited by active contacts, internal users, and monthly build credits used for creating and editing apps; live apps run without consuming credits. Paid plans include a set number of apps with options to add more, and add-on credits are available.
