Build an AI Roofline Lighting Preview App

1. 1

   Position against the contractor platform

   Sibling card ai-light-design-contractor-saas is the full B2B estimating-and-contract suite; this is a lighter, consumer-facing preview app aimed at the permanent-lighting market. Keep it focused on one delightful job: trace your roofline, see realistic lights instantly. That focus is what makes it buildable and lovable rather than a bloated tool.

2. 2

   Nail the trace-and-render experience

   Let the user upload a photo and trace the roofline (assisted or automatic), then render realistic bulb placement, spacing, color, and wall-wash projection so the preview looks like the real result. The visual quality is the product; if it looks convincing on a phone, people share it and installers want it.

3. 3

   Aim it at permanent lighting

   Design around the permanent-lighting use case, multiple colors and holidays on one fixed system, since that is the growing market and the previews are more compelling. Let users try different scenes (Christmas, Halloween, game day, warm white) on their own home, which is exactly the flexibility that sells permanent installs.

4. 4

   Choose the monetization

   Two paths: charge consumers a small subscription or one-time fee for the app, or, stronger, run it free for consumers and sell the qualified leads to permanent-lighting installers who pay for homeowners who have already visualized a design on their house. The lead-gen model aligns your growth with the installers booming in the permanent-lighting card.

5. 5

   Launch and grow the app

   Ship on the app stores, optimize the listing for searches like light visualizer, and seed it through social sharing of before-and-after previews. Partner with installers who can promote it to their prospects. Because previews are inherently shareable, organic and referral growth can carry a well-made app.

6. 6

   Feed the install ecosystem

   Build a clean handoff from a finished preview to a quote request routed to a local installer, and let installers claim a territory or pay per lead. That turns your app from a toy into the top of the permanent-lighting sales funnel, which is where the durable revenue is.
