Desktop AI SaaS for vehicle salespeople and dealerships. It turns an inventory URL into a Facebook Marketplace-ready listing while working from the seller’s local session.
My own product: I am the founder, product owner, and the person building the application, backend, and operation.
Living case study · Updated August 2026.
The challenge
Publishing inventory on Marketplace forces sellers to jump between the dealer website, photo folders, and Facebook: copying VIN, mileage, price, description, and images for each unit. With dozens of vehicles, the work repeats every day and sold listings become outdated.
How the product evolved
- Import from one URL — extracts information, price, VIN, specifications, and photos from industry inventory websites.
- AI-assisted content — prepares buyer-oriented titles and descriptions and lets users review everything before publishing.
- Local publishing — automation works from the user’s Facebook session on their computer without asking them to hand their password to an external service.
- Application for macOS and Windows — Electron, Next.js, React, and TypeScript with updates, signing, licensing, and per-device activation.
- SaaS backend — authentication, Stripe subscriptions, admin dashboard, devices, and account operations.
- Beyond cars — the public workflow now includes boat, RV, powersports, trailer, and commercial-equipment dealers.
- Guided onboarding — the offer includes guidance to validate the inventory source, local session, and first publish.
Current state
CarSocial moved from validating its first subscription to a public SaaS offer of $99 per month, with onboarding and a multi-vertical strategy. The product continues to evolve from real usage and the obstacles sellers encounter.
It is a complete end-to-end product: desktop application, extraction, AI, browser automation, backend, payments, licensing, infrastructure, and signed distribution.
