Turn your agency’s know-how into AI-built apps
A branded client portal for your agency’s work — and AI to build what sets you apart.
Assembly gives your agency a branded client portal for reports, approvals, invoices, and files. Use AI to build what sets your agency apart, from analytics dashboards to design review apps.
Stop scattering your deliverables across tools
Feedback in one app, files in another, reports in a third, invoices by email. Clients ask where things stand because they can't see it.
“We were dealing with scattered emails and no good way to share information with clients.”
Ready-made apps for how agencies deliver
Start with 30+ working apps, from design approvals to proposals clients sign and pay. Install one, then reshape it by describing the change.
Browse all templatesRetire a subscription. Build the app instead.
Describe what you want. The builder asks a few questions, shows a one-page plan, and builds after you approve. Every app knows your clients from the built-in CRM.
Add a project tracker each client sees for their own campaigns.
Step One:Describe it
Tell the AI what you need, like a project tracker or a campaign report.
Step Two:Answer a few questions
It asks one to three questions so the app fits how your agency works.
Spring Campaign
Brand Refresh
Q3 Paid Social
Step Three:Approve and it appears
The app shows up in your client experience with logins, permissions, and your branding in place.
Every client gets their own branded view
Custom fields decide which apps each client sees — your top tier books strategy sessions, everyone gets the monthly report. Every app carries your logo and colors.

Embed Figma, Canva, Looker Studio, ClickUp, and Calendly so clients see them inside your client experience. Connect the rest with Zapier, Make, the API, or MCP.

What agencies ask before moving clients
They sign in with Google or a one-click email link, and can reply to messages straight from email.
No. It runs inside your client experience with logins, permissions, and your built-in CRM from the day you publish it.
You can, but you would set up logins, per-client data, and hosting yourself. On Assembly those come with the platform, along with ready-made apps for billing and files.
Embed Looker Studio, Databox, or Power BI and add your commentary in a report app. Dedicated reporting tools have more native data integrations, and many agencies use both.
Not natively. Embed Loom or YouTube for walkthroughs, and keep a dedicated video review tool for frame-accurate comments.
Yes, on Professional and above, which also removes the Assembly badge. Your logo and colors work on every plan.
Yes. Clients see your logo and colors, and every app you build carries your brand. Your own domain comes with Professional.
