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 Invoicing App Builder for Garden Centres

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.

Stop rebuilding the same invoice in a document every week. Tell Mythex how your garden centre charges and it builds an invoicing app with clients, line items, totals, tax and a paid/unpaid list.

Who it's for

Owners of garden centres who want invoices numbered, stored and searchable without paying per month for accounting software.

What you can build

Clients with billing details and payment terms
Invoices with line items for plants and garden furniture, tax and totals
A PDF you can download or email to the customer
A paid / unpaid / overdue list with what is due this week
Quotes that turn into an invoice once accepted

A prompt to start from

Build an invoicing app for a garden centre. Keep a list of clients with customer name, item and quantity. Create invoices with a number, date, due date, line items for plants, garden furniture and landscaping supplies, quantity, rate, tax and total. Generate a printable PDF, mark invoices paid or overdue, and show a dashboard of outstanding money. Add quotes that can be converted into an invoice, and store everything in a database.

Questions

Can it produce a PDF?

Yes. Ask for a printable invoice and Mythex builds a clean PDF layout with your details, logo and numbering, which you can download or attach to an email.

Does it handle tax?

Say which tax applies and at what rate and it is calculated per line and shown in the total. If you bill in more than one currency, say that too.

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.
