AI Client Portal Builder
Describe what your clients should see when they log in, such as their files, the status of their work, their invoices and a thread with your team, and Mythex builds the client portal with sign-in, a Postgres database and file storage behind it. Publish it 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?", the portal is where the answer lives. With one client and nothing sensitive, a shared document may be enough.
What you can build
- A portal where each client sees only their own projects and files
- Milestones and status updates posted by your team
- Two-way file sharing: deliverables out, documents in
- An invoice list per client with sent, paid and overdue status
- A message thread per client instead of scattered email
- A staff side listing every client 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, check for client logins by invitation rather than open sign-up, every query scoped to the signed-in client, file sharing on real storage, clear status for each project, and messages tied to the client so history stays in one place.
- Invite-only client logins
- A wall between clients' data
- File sharing in both directions
- Status, next steps and invoices
- Messages attached to the client or project
Building the portal with the client portal builder
Start with what a client needs to see in ten seconds: status and next steps beat a long wiki. Turn on the database for projects and requests and file storage for uploads. Ask for a client role and a staff role, then test the wall yourself by logging in as two different clients in the preview. Add invoices, messages and notifications in later messages once the basics hold.
Your domain, your branding
Every published app gets a free Mythex address, and on Pro ($25/month) you connect your own, such as portal.yourfirm.com. Colours, logo and wording follow your brand because the portal is your own code. Pro also adds code export and GitHub sync if your IT team wants to review or host it. E-signatures and invoicing are not built-in products, so connect the services you already use for those through their APIs.
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, an upload area for files we need, their invoices with status (sent, paid, overdue) and a message thread with our team. Add a staff area to see every client, create projects, post updates, upload files and reply to messages. Use a Postgres database with per-client access and file storage.
Questions
How do I build a client portal in Mythex?
Describe it in chat, in English, Arabic or another language, 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 database and storage. Then refine it the same way and publish when it is ready.
Can each client see only their own data?
Yes, and that is the first thing to test. 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. Log in as two different clients in the preview to confirm it.
Can clients upload files?
Yes. Uploads go to the project's file storage, linked to the client and project in the database. You can ask for size or file-type limits and for a notification to your team when something new arrives.
Is there a free client portal builder?
You can build and publish a portal on the Free plan with no credit card. Pro is needed for your own domain, code export and GitHub, which most firms want before sending the link to clients.
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.
