With Claude Fable 5 — Anthropic's most powerful public model, released June 9, 2026 — you can build a complete lead-generation app in a weekend. It scans aerial imagery to find homes that need your service, renders a photorealistic "after" image of each property, and mails a personalized postcard with a booking QR code, all from a single prompt in Claude Code.
Let me show you what's now possible. Imagine a contractor who could mail every fenceless home in a zip code a postcard showing their own backyard — with a brand-new fence already on it — and a QR code to book the job. A year ago, that was a six-figure software project. This week, it's a weekend.
I saw a version of this build making the rounds on X, and it stopped my scroll. So I broke it down into the exact stack and the exact prompts you'd paste in. Here's how it works.
What can Claude Fable 5 actually build?
Anthropic released Claude Fable 5 on June 9, 2026 — its most capable model available to the public. It's state-of-the-art on nearly every software-engineering benchmark, and here's the part that matters for us: the longer and more complex the task, the bigger its lead over older models. Building a full app — database, AI vision, image generation, and a mailing integration, all wired together — is exactly the kind of long, multi-step job where Fable 5 shines.
That's what makes this realistic for a non-coder. You describe the system in plain English inside Claude Code, and Fable 5 writes the app, sets up the database, and connects the services for you.
What's in the stack — and what does each piece do?
Six tools do all the work. In plain English:
- GitHub — holds your code.
- Vercel — runs the app and the weekly automation.
- Supabase — your database (stores addresses, images, and lead status).
- Claude API — looks at aerial photos and spots the homes that need your service.
- An image-generation API — creates the "after" picture of their property.
- Lob — prints and mails the postcards automatically.
You don't have to understand how each one works under the hood. Fable 5 does the wiring — you just bring the accounts.
What exactly do you paste into Claude Code?
Two prompts. Use the first if you want the fence-business example as-is. Use the second for any home-service business — just fill in the brackets. Open Claude Code, paste, and let Fable 5 build.
Build a lead-generation web app with Next.js on Vercel, Supabase, and GitHub. I enter a zip code, and the app: (1) pulls residential addresses from that county's public parcel/assessor data, (2) fetches an aerial image for each address from county GIS orthophotos, (3) uses Claude's vision API to flag homes with a yard but no fence, (4) for each qualified home, uses an image-generation API to render that yard with a new fence, (5) generates a unique QR code per address linking to a landing page showing their rendered image and a booking button, and (6) sends a postcard with the render and QR code via the Lob API. Include an admin dashboard where I review flagged homes and approve/reject before mailing. Store everything in Supabase with a status pipeline (found → qualified → rendered → approved → mailed).
I run a [TYPE OF HOME SERVICE BUSINESS — e.g., landscaping, roofing, pool installation, exterior lighting]. Build me a lead-generation web app (Next.js on Vercel, Supabase, GitHub) where I enter a zip code and the app: (1) pulls residential addresses from public parcel data, (2) fetches an aerial image of each property, (3) uses AI vision to find homes that show [THE VISUAL SIGN THEY NEED MY SERVICE — e.g., a patchy lawn, aging roof, dark unlit yard], (4) renders an "after" image of that property with [MY SERVICE RESULT — e.g., fresh landscaping, new roof, night lighting], (5) creates a unique QR code per home linking to a page with their before/after images and a booking button, and (6) mails a postcard via the Lob API. Include an approval dashboard so I review leads before anything is mailed.
One important caveat: Start with free county GIS imagery, not Google Maps. Google's terms don't allow reprinting their map images on marketing mailers — county orthophotos are public and built for this.
The hard part of this was never the code — it's the orchestration: pulling parcel data, scoring images with vision, generating a render, and triggering a print job, all in sequence with a human approval step in the middle. That glue used to require a developer. Fable 5 writes it. Don't try to boil the ocean: start with one zip code and one service, watch the approval dashboard fill up, and only scale once the postcards are actually booking jobs.
Try it this weekend
Pick one zip code. Pick one service. Paste the prompt into Claude Code and see what Fable 5 builds. The barrier here isn't technical skill anymore — it's deciding to start.
When you've got something running, hit reply and tell me what you built. I read every response, and the best ones might end up in a future issue.
The tools to run a personalized, AI-powered direct-mail funnel now cost less than a nice dinner — and Claude Fable 5 writes the code for you. Find the home, render the "after," mail the postcard. One zip code, one service, one weekend.
