Assembly combines an AI app builder with a CRM and branded client experience for building client-facing apps and internal tools. Users describe an app in plain language, review a proposed plan, publish it, and refine it through 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 can link the workspace to tools including ChatGPT and Claude for analysis and workspace actions. Published apps appear together in the workspace sidebar. Assembly handles client authentication, roles, permissions, and client data scoping through its platform rather than generated AI. It says its platform is SOC 2 Type II certified and offers HIPAA support with a BAA on Advanced; AI features are not covered by that support. A free plan is available, with Starter at 29.00 USD per month billed annually; the listed monthly billing price is $49. Desktop apps are offered for macOS and Windows, alongside the web app.
Who it is for
Assembly suits teams building authenticated client experiences or internal tools around requests, projects, proposals, or support. It is not suited to public-facing websites, public directories, or consumer apps.
What is good
- Offers more than 30 workflow templates.

- Workspace and client data are not used to train AI models.
What to know first
- Not suited to public-facing websites or consumer apps.

Verdict
