Micro-App Builder

Micro-App Builder creates small, embeddable HTML tools for your website — calculators, checklists, quizzes — that give visitors a reason to stay and leave their email address. You describe what you sell, pick one of three AI-generated ideas, and get a finished app with preview, source code and embed code.

The apps are AI-generated from your description (the code is sanitized and sandboxed before preview). Note the pricing: the full flow is two AI runs — idea generation and building — at 50 credits each, so up to 100 credits total, and the charge happens without a confirmation dialog. In your credit history the charge is currently recorded under the name "widget-smith" (as of 2026-08-06).

Who this tool is for

Anyone who wants interactive lead magnets on their site without commissioning development.

Prerequisites

• Signed-in account
• Up to 100 credits for the full flow (50 for ideas + 50 for building); identical input may hit the cache and be free
• A concrete description of what you sell

How to use it

1. Describe what you sell, plus industry, audience and brand name if you have them.
2. Pick one of the three ideas (this step is the first 50-credit charge).
3. Adjust colours, email capture and optional webhook, then build the app (the second 50-credit charge).
4. Preview in desktop/tablet/mobile and light/dark, then grab the code: copy HTML, copy the embed snippet, or download the file.

How to read the result

• The preview tab shows the app as visitors see it — test the email capture there.
• The embed snippet is an iframe you paste into your CMS; the webhook URL receives submitted emails.
• The code is self-contained HTML — it can also be hosted anywhere.

Common errors

• "Could not parse the ideas": a rare failure after the idea run; the credits for that call are not auto-refunded today — contact support.
• The app looks generic: describe product and audience more specifically before regenerating ideas.

Limitations

• No saving or history — download the HTML file before closing.
• Generated code is deliberately restricted (no storage/iframes inside the app) for security.
• This tool is separate from Micro-App Factory, a different builder with its own guide.
