Assembly delivers a modern, branded client portal built for seamless two-way communication
Assembly's portal was built portal-first — it's the core product, not an add-on feature. Clients get a fully white-labeled experience with magic-link passwordless access, reply-via-email messaging, embedded third-party tools like Calendly and Airtable, and app visibility rules that let you show different tools to different clients.
