You can build the app in a chat. Now give it a place to live.

Sign-in, records, rules about who sees what, payments and a live address, all set up by asking. Keep working from Claude, ChatGPT, Cursor or any AI that connects, and hand the app to a client when it’s done.

  6. Your team

  1. Connect

    Your AI can write the app, but it has nowhere to put it

    Connect your AI once, in about two minutes. Claude and ChatGPT need no token: you sign in and click Allow. Claude Code, Codex, Cursor and other coding tools use the same link. After that, any chat can publish and update your apps.

    A real template: Chapter. Preview it (opens in a new tab)

    You type in your AI chat

    Deploy on PageLemon.com

    Later, you might ask

    • “Which of my apps is live?” Your AI lists your sites and says which are on, with their addresses.
    • “Use my Cursor to edit the same app” Connect Cursor with the same link. Your AI there sees the same sites and the same history.

    Free: connecting is freeUndo anythingSecurity

  2. First build

    You have an idea, and you’d like to start from something that works

    Start from a ready-made app, such as a client portal, an expense log, a habit tracker or a paid community, and ask for your changes. Your AI sets up the sign-in, the lists and the pages, and gives you a link. You switch the app on yourself.

    You type in your AI chat

    Build with PageLemon.com: a client portal for my coaching, where each client sees their sessions left and sends a check-in before each session

    Later, you might ask

    • “Show me the app as a client sees it” Your AI gives you a sign-in link for a test user, who never counts towards your users.
    • “Use the Chapter template instead” Your AI starts from that app and changes it to what you asked for.

    Step-by-step guide

  3. Real users

    People other than you need to use it

    Give your AI their email addresses. Each person gets an invitation only after you say yes, and signs in with a code sent to their email. They don’t need a Page Lemon account. Each sees only their own records, and you see everything in your Dashboard.

    You type in your AI chat

    Invite the people on this list to my app, and show me the emails before they go

    Later, you might ask

    • “Let people ask to join, and I’ll say yes or no” They ask from the sign-in page and see nothing until you answer.
    • “Remove Jo from the app” You approve it on a link, and Jo’s access ends then.

  4. Changes

    Your first users ask for changes, and you break something

    Every change you make from any AI is saved as a version that shows who made it, and which AI. See what changed, and undo it. Ask for the change from whichever AI you have open that day.

    The Expense log template: An app template: a small studio’s own expense claims app. Staff sign in with their email, photograph a receipt on their phone and claim it in under a minute, follow each claim from Submitted to Approved to Paid, answer the office manager’s questions, and see what they are owed and their monthly totals. The office manager approves and replies in the Dashboard. A public page, six member screens under /app (Home, Add, Claims, Months, Policy, Account) and a privacy notice with blanks.

    Who changed the sign-up page, and put it back how it was yesterday

    Later, you might ask

    • “Show me what changed this week” Your AI lists the versions, who made each and what moved.
    • “Add a question to the sign-up form: what do you want it for?” It’s on the form from now on, and shows with each sign-up.

  5. Money

    Somebody wants to pay for it

    Add a plan with a price, monthly or yearly, and users pay on your own Stripe account. Renewals, failed payments and cancellations open and close their access by themselves, and a free plan can sit beside the paid one.

    Add a paid membership to my app: a yearly subscription for full members, paid to my own Stripe

    Later, you might ask

    • “Free members add 10 entries a month, paying members as many as they like” A rule by plan, set in one sentence.
    • “Put it on my own domain” Your AI gives you a link showing each step at your domain company.

    Step-by-step guide

  6. Your team

    A teammate or a developer joins, and later the client takes over

    Invite a teammate with their own AI, or someone who can only look. When the app is finished, hand it to a client: it moves to them with every version, its domain and its users’ records, and you can ask to stay on to keep working on it.

    You type in your AI chat

    Transfer my app to client@example.com and ask to stay on as a Developer

    Later, you might ask

    • “Invite sam@example.com to edit my apps” Sam gets an invite, and the changes Sam makes show who made them.
    • “I need to call the app from my own code” Your AI gives you the API address and a key. See the API backend page.

Questions

Which AIs can I use?

Claude, ChatGPT, Claude Code, Codex, Cursor, VS Code, Antigravity, Gemini CLI, Windsurf, Cline and any other app that speaks MCP. See connect your AI.

Do I need to know how to code?

No. Your AI writes and changes the app, and you say what you want. If you do code, the MCP server and the API are there too.

Do my users need an account or an app?

No Page Lemon account and no download. They sign in on your site with a code sent to their email, and can add it to their phone’s home screen.

Can I keep my front end somewhere else?

Yes. Use Page Lemon as the sign-in, the data and the rules, and call it from your own front end. See API backend.

Can I undo a change my AI got wrong?

Yes. Every change is saved as a version that shows who made it, and any change can be undone.

Can I work on it with someone else?

Yes. Invite a teammate to edit with their own AI, or someone who can only look. Every change shows who made it.

Can I hand the app to my client?

Yes. A site can be handed over to another account with its versions, domain and users’ entries. You can ask to stay on as a Developer. See hand-over.

Who pays for the AI in my app?

You do, through your own AI key from OpenRouter, OpenAI, Anthropic or another listed provider. Try it first on ours, free for 3 days or 10 requests. See AI in apps.

Is there anything I can’t put in it?

Yes. Apps are for adults only, and not for health, mood or therapy records, or for card, bank or ID numbers. Your AI will say no and offer something else.
