What is Mythex and how does it work?

Mythex is an AI app builder. You describe what you want in plain language; Mythex builds a working app with live preview, then you publish with one click.

How is Mythex different from other AI builders?

Mythex combines simple plain-language building with a real workspace — live preview, code, terminal, database, export, and one-click publish in one place. Side-by-side comparisons live at https://docs.mythex.ai/introduction/compare

How is this different from ChatGPT?

ChatGPT can suggest ideas. Mythex builds a real app you can open, try, and publish — with preview, code, and hosting in one place.

AI Client Portal Builder for Fintech Startups

Q: Do I need to know how to code?

No. You can build by chatting in plain language. If you do know code, you still get a full editor and terminal when you want to dig in.

Give users somewhere to log in. Describe what your fintech startup shares with them — documents, progress, invoices, messages — and Mythex builds a portal with accounts, permissions and a real database behind it.

Who it's for

Teams at fintech startups who need clients to see their own information — and only their own — without building auth from scratch.

What you can build

A login where each user sees only their own records
Documents and files you upload, available to download
Status or progress on the product and waitlist access
A message thread between the user and your team
A staff view listing every user and their history

A prompt to start from

Build a client portal for a fintech startup. Users log in and see only their own records: user name, email, plan and signup date, files we uploaded for them, and the status of the work we are doing for them. Add a message thread per client and a staff area where our team can see everyone, add records, upload files and reply. Use a database with proper per-user access.

Questions

How does login work?

Ask for accounts and Mythex builds sign-in into the app. Each published app has its own users and its own data, separate from your Mythex account.

Can clients only see their own data?

Yes, and it is worth saying out loud in the prompt. Mythex scopes each query to the signed-in user, so one client cannot open another's records by changing a URL.

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.
