1億円規模!動画掲載式車売買プラットフォーム

This is a car sales and purchase web service created from scratch by a real used car dealer in Osaki City, Miyagi Prefecture using Claude Code and Codex over 196 days.

• Like TikTok, inventory car videos scroll vertically (with sound)
• Anyone can list their car for free (private sales, zero listing fees)
• When you photograph the vehicle registration certificate, vehicle information is automatically populated
• Currently operating in the actual physical store. There are also listing records from people in distant areas with no prior connection.

All development records have been kept with actual measurements (1.96 million lines of conversation logs with AI, 41GB, called the AI a "liar" 220 times). Details are written in the note article "Until an idol creates a giant platform through vibe coding."
