Marketplace Studio
A phone-first resale tool: photograph an item, let an agent research it, get a ready-to-post listing.
- Role
- Design and implementation
- Status
- Working · private use
Marketplace Studio is a private tool for preparing resale listings. You photograph an item and start a research job; a sandboxed Codex worker uses vision and web search, asks a few focused follow-up questions, then drafts the listing and a price.
A browser extension fills Facebook Marketplace's create-item form from the draft. Publishing is always a manual click.
Engineering highlights
- Agent output is structured and validated on the server before it touches a listing.
- Durable jobs with cancel and retry; each item gets its own chat room for follow-up questions.
- Releases switch via symlink with automatic rollback when the readiness check fails.
