Build an AI App in Minutes with Emergent — The “Room to Move” Walkthrough 2026

If you’ve ever wished you could turn an app idea into a working product without hiring developers or wrestling with infrastructure, Emergent changes the game. Emergent isn’t just a no-code toy — it’s “vibe coding”: you write a text prompt, the system writes real Python under the hood, and a fully functioning app appears in a matter of minutes.

Below I’ll walk you through the exact process used in the demo app Room to Move — an image-based moving estimate tool — so you can replicate the same steps and embed affiliate CTAs where appropriate.

What is Emergent (quick answer)

Emergent is an AI-first app builder that generates frontend, backend, business logic, and the database from a single text prompt. It integrates LLMs automatically (no API keys required), supports GitHub sync, and exposes controls that let you tune the build — agent model, templates, and privacy settings are all first-class.

In short: idea → prompt → product. (All details below are taken from the demo walkthrough.)

What does emergent make different from other app?

Most AI coding assistants still require you to know programming. They’re like having a really smart pair programming buddy. Vibe coding? It’s like having an entire development agency that speaks your language.

The platform uses a conversational interface instead of drag-and-drop builders or form-based tools. You literally chat with it like you’re texting a friend who happens to be a brilliant developer.

Step 1 — Start with a clear prompt

The process begins in the prompt box. You don’t need to over-engineer it, but be specific enough for the agent to understand the app’s core: name it, state the main user action, and list the expected outputs.

Demo prompt example (paraphrased):
 “Create an app called Room to Move. Users upload photos of rooms; the AI detects items, estimates packing volume/weight, and calculates a moving cost. Include editable item lists, export CSV/PDF, and deployment-ready UI.”

Step 2 — Use Emergent’s UI controls

Before sending the prompt, explore the prompt box features:

• File (paperclip) — attach reference images or documents.
• GitHub connect — link repo for saving generated code.
• Agent selector — choose Emergent’s default agent (E1) or faster variants; mobile-specific agents are available.
• Ultra Thinking — deeper reasoning; pro-only.
• Model selector — choices include Claude 4.0 Sonnet, Claude 4.0 Extended, or GPT-5 (if available to you).

• Advanced controls — toggle integrations (Supabase, Notion, custom servers), select a template (full-stack recommended), and set a build-credit budget.
• Privacy toggle — choose private or shareable project.

These options let you match resources and integrations to your needs. Use templates for faster results.

Step 3 — Let the agent run and collaborate

After you hit send, the agent (Neo in the demo) builds the app iteratively. Crucial points from the demo:

• The agent will ask clarification questions (e.g., which model for image analysis, pricing logic, detection accuracy). Answer in chat to refine the build.
• You can watch a live preview on the right panel while the left panel shows chat and logs.
• The agent performs testing (a “testing agent” QA pass) and reports errors and fixes inside the chat — the system even runs the testing agent again for verification.

This hands-on chat loop is how you design, test, and refine without touching code.

Step 4 — The Room to Move flow (image analysis → estimate)

In the demo app the user:

1. Uploads images (up to six at once).
2. Clicks Analyze Room — the app processes images, detects items, and lists them with estimated volume, weight, and cost.
3. The list is editable: you can adjust or delete items, add custom items, and tweak detection accuracy.
4. Enter moving details (home type, floors, elevator, distance, packing option).

1. Click Calculate Estimate — the app produces an itemized list and a summary panel with the total (e.g., $4,900 for a 50-mile full-service move).
2. Export — CSV works in the demo; PDF export was initially broken but the AI agent fixed it after a chat request.

Because Emergent writes real code, you get CSV/PDF export and can ask the agent to debug live issues.

Step 5 — Iterate: UI refresh & bug fixes

Want a cleaner UI or a bug fix? Open the chat and tell the agent (e.g., “refresh UI with a modern look” or “fix PDF export”). The agent will:

• Apply changes, list design and code changes in the chat, and
• Rebuild & test automatically.

This is the power of agent-driven, iterative app development.

Step 6 — Deploy and connect a custom domain

Deployment options from the demo:

• Generate a preview subdomain (temporary link for demos, ~30 minutes).
• Run a pre-deployment health check (agent code review for environment variables, DB connections, security). This uses credits.
• Start deployment (costs credits — e.g., demo used 50 credits per deployment month). Deployment typically takes several minutes and shows step-by-step status.
• To use your own domain, Emergent provides domain linking and can integrate with Entry to automate DNS updates with registrars like Hostinger domain. (Note: DNS propagation can take minutes to 48 hours.)

Why Emergent Changes Everything

Let me break down what just happened. We went from a simple text idea to a fully functional, AI-powered app deployed on a custom domain—all in under an hour.

No coding. No developers. No endless tutorials.
