AI Client Portal Builder
Describe what your clients should see when they log in — their files, the status of their work, their invoices, a thread with your team — and Mythex builds the portal, with sign-in, a Postgres database and file storage behind it, published to a URL you control.
Who it's for
Agencies, consultancies, accountants, law and architecture firms, and any B2B service that sends clients the same updates and documents by email. If clients keep asking "where are we on this?", a portal is where the answer lives.
What you can build
- A portal where each client logs in and sees only their own projects and files
- Status updates and milestones per project, posted by your team
- Shared documents: you upload deliverables, clients upload what you asked for
- Invoices and their status — sent, paid, overdue — per client
- A message thread per client instead of scattered email chains
- A staff side listing every client, their projects and their history
What a client portal needs
A client portal is two apps sharing one database: the client's view, which must only ever show their own data, and your team's view, which sees everyone. Whatever you build it with, it needs:
- Client logins, with an invite from your team rather than open sign-up, so only real clients get in.
- A wall between clients: every query scoped to the signed-in client, so one client can never open another's records or files.
- File sharing in both directions — deliverables from you, documents from them — stored on real storage, not in email attachments.
- Status and updates: where each project or case stands, what is waiting on the client, and what happens next.
- Invoices and payment status, so clients can find what they owe without asking.
- Messages tied to the client or project, so the history is in one place when someone on your team picks it up.
A prompt to start from
Build a client portal for a services business. Clients are invited by email and log in to see only their own projects: status, milestones, files we uploaded for them and an upload area for files we need from them, their invoices with status (sent, paid, overdue), and a message thread with our team. Add a staff area where our team sees every client, creates projects, posts updates, uploads files and replies to messages. Use a Postgres database with per-client access and file storage for uploads.
Questions
How do I build a client portal in Mythex?
Describe it in chat, in English or Arabic — for example "a portal where each client logs in and sees their projects, files and invoices". Mythex writes the code, runs it in a live preview, and attaches a Postgres database and file storage. Then refine it the same way: "add a status timeline to each project" or "let clients upload signed documents". Publish to a public URL when it is ready.
Can each client see only their own data?
Yes, and that is what to check first. Ask for per-client access and Mythex scopes every page and query to the signed-in client, with a separate staff role that sees everyone. Test it in the preview by logging in as two different clients.
Can the portal be on our own domain?
Yes. Every published app gets a free Mythex address, and on Pro ($25/month) you connect your own domain, such as portal.yourfirm.com. Pro also adds code export and GitHub sync.
What does the Business plan add for a firm building portals?
Business, from $50/month, is for teams: a shared workspace with Admin, Editor and Viewer roles, private projects, sign-in with Google Workspace SSO on your verified company domain, joining by company email, and members-only apps for internal tools only your team can open. Your clients still log in to the portal itself, which works on any plan.
Do I need to know how to code?
No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.
Do I have to explain my business every time?
No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.
How much does it cost?
There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
