Upload Photos
Upload at least 2, ideally 3 photos of your item. Photo quality significantly affects analysis accuracy.
Best practices for optimal photos:
Photo 1: Overall View (Front)
Shows the entire product from the front in good lighting
Photo 2: Brand & Model
Close-up of brand names, labels, or model designations
Photo 3: Condition & Details
Shows any signs of wear, scratches, or special features
Important:
- • Use good lighting (daylight ideal)
- • Clear, sharp images (no blur)
- • Prefer neutral backgrounds
- • Brand/model should be readable
AI Analysis Running
After upload, the AI analysis starts automatically. This process takes about 20-40 seconds and runs in several steps:
Image Analysis (10-20 seconds)
Google Gemini or OpenAI GPT analyzes your photos and recognizes category, brand, model, material, color, and condition
Market Data Matching (5-10 seconds)
Parallel query of current selling prices on eBay Classifieds and other platforms via Serper API
Price Calculation (3-5 seconds)
Combination of AI assessment and market data yields a realistic price range (Min-Max) and recommendation
Text Generation (3-5 seconds)
Creation of professional listing text with product description, condition report, and selling points
Good to know:
During analysis, we show you (for free accounts) relevant advertising. This keeps ResAiler free for you!

💡 Pro Tips for Better Results
🎯 Better Photo Quality
The clearer the brand and model are visible, the more accurate the price estimate. Close-ups of labels help enormously!
📊 Combine Market Research
Compare the AI recommendation with current offers on eBay Classifieds. This gives you a feel for the current market situation.
✍️ Personalize the Text
The generated text is a solid foundation. Add personal details (e.g., "Used only for vacations") for more authenticity.
🔄 Use Fine-tuning
If the first analysis isn't perfect, use the fine-tuning function with additional information. The AI learns from your input!
💰 Plan for Negotiation
Set the starting price slightly higher than the recommendation to leave room for negotiation. 10-15% markup often makes sense.
