Assembly vs Client Hub

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.

Client Hub is accounting practice management software that turns client communications into trackable work and supports workflows such as month-end close. Teams can create jobs with checklists, task owners, deadlines, statuses, and recurring schedules. Each client gets a workspace for file uploads, requests, and communication with the firm. AI tools can draft replies, summarize email threads, generate workflows and client tasks, and surface insights from reports. Client Hub connects with QuickBooks Online and Xero for transaction workflows and two-way syncing. Other integrations include Anchor, Gmail, Microsoft Outlook, SignWell, and Zapier, which connects to over 5,000 applications. It is available on the web, iOS, and Android. The mobile apps support messaging, tasks, documents, and real-time notifications, and show the 20 most recent documents; older files are available on the web. Pricing starts at $49/user/mo (annual), with a 14-day trial and no free plan. Charges are per firm user, while plans include unlimited clients and storage. The company says it encrypts data in transit and at rest and backs up data daily.
