Introduction
What Sellu is and how it helps you sell faster.
Sellu is a browser extension that puts your reselling on autopilot. It works directly inside your marketplace account — starting with Vinted across 27 countries — and automates the repetitive work of running a shop: reposting listings, filling in new listings with AI, replying to buyers, handling offers, and printing labels.
What it can do
- Smart repost engine — relist items in one click to reset your search ranking, with photo variations and optional price drops.
- AI listing autofill — generate titles and descriptions from your photos, in the marketplace's own language, using your own OpenAI or Anthropic API key.
- Bulk wardrobe management — repost, duplicate, reprice, edit, hide, or delete many listings at once, with CSV import/export and your own SKU/location inventory fields.
- Inbox automation — quick replies, bulk replies, and an AI smart agent that answers buyer questions.
- Auto-offers — automatically accept or counter incoming offers based on your thresholds.
- Automations engine — five scheduled background jobs: restocker, follow-ups, smart agent, offer handling, and view boosting.
- Orders & shipping — bulk shipping-label PDFs (merged, cropped, stamped), bulk reviews, and order CSV export.
- Templates & quick replies — reusable listings with dynamic variables, and one-tap message snippets.
- Account safety — human-like pacing, daily caps, and automatic captcha/rate-limit handling on every action.
Each feature page includes a short demo video.
