Conversational app building
Describe an app in plain language, review the generated plan, and publish a real app to your workspace. The builder supports continued refinements by chat after launch.
Assembly Studio
Assembly Studio is an AI app builder for professional services firms, with production-ready client portals, internal tools, built-in authentication, CRM and workflows.
What Assembly Studio is
Assembly Studio is an AI app builder for professional services firms that need client-facing apps and internal tools without assembling a stack of separate products. It turns a plain-language description into a working app, then places that app inside a branded client experience with built-in authentication, CRM, workflows, and other platform components.
The product is positioned for firms that want to publish production-ready applications rather than temporary prototypes. Source materials show use cases such as client onboarding, document collection, time tracking, project tracking, approval workflows, proposal building, client dashboards, and AI assistants that answer questions from a firm’s own documents.
Core capabilities
Built-in client portal
Apps ship inside a branded client experience on your own domain, with client sign-in, sidebar navigation, and no separate hosting setup for the end user.
Platform foundations included
The platform includes a CRM foundation, workflows, notifications, roles and permissions, authentication, and integrated payments so apps do not start from a blank slate.
Template-led starting points
Pre-made templates cover onboarding, trackers, approvals, proposals, AI assistants, support, and internal resources, giving teams a starting point they can reshape by chat.
Plan-based admin and security controls
Paid plans introduce controls such as custom domains, removal of Assembly branding, app visibility, automation builder, AI model selection, audit logs, client access permissions, enforced MFA, and custom SSO at higher tiers.
Usage-based build capacity
The pricing model uses build credits for app creation and edits, while live apps continue running without consuming credits. Extra build credits and extra apps can be added as needed on paid plans.
Common workflows
Client onboarding and service delivery
Create a client portal for onboarding, document collection, status updates, or support so clients can complete tasks and see progress in one branded place.
Internal operations tracking
Build an internal tracker for hours, project milestones, approvals, or case status when the team needs a structured tool that is separate from the client-facing view.
Proposals and approvals
Generate proposal, pricing, or e-sign flows that let a firm present work, collect approvals, and keep the process inside the client experience.
Template-based customization
Use the built-in templates as a starting point, then adapt the app by chat to match an agency, accounting, or consulting workflow without rebuilding the basics.
Document-backed self-service
Add an AI assistant that answers client questions from the firm’s own documents, or build other document-driven apps such as resource libraries and data rooms.
