KassenBonBon

KassenBonBon is your personal shopping intelligence platform. Upload your grocery receipts and instantly get detailed spending analytics, category breakdowns, nutrition insights, budget tracking, price alerts, and AI-powered recommendations — all in one place. It turns your everyday receipts into actionable knowledge about your shopping habits.

KassenBonBon offers a generous Free plan that includes up to 30 receipt uploads per month, basic analytics, AI-powered product categorization, budget tracking, and barcode scanning. For power users, our Pro plan (€3.99/month or €39/year) unlocks unlimited uploads, advanced analytics, nutrition tracking, anomaly detection, basket analysis, weekly AI reports, and more. No credit card required to get started.

It's as simple as 1-2-3: Create a free account, upload your first receipt (PDF or photo), and within seconds you'll see your purchases categorized and analyzed. Your personal dashboard builds up automatically with every receipt you add — complete with spending trends, budget tracking, price alerts, and AI insights.

KassenBonBon supports receipts from all major German retailers including REWE, Lidl, Aldi, EDEKA, Kaufland, and more. Our intelligent parser automatically detects the store and adapts its processing. Even receipts from unknown stores are handled by our generic parser.

Go to the Upload page in your dashboard, then simply drag & drop your receipt file or click to select one. You can upload PDF receipts from online shopping, or snap a photo of your paper receipt with your phone (PNG, JPG). Multiple files can be uploaded at once — batch processing makes it quick and easy.

Absolutely! Just take a photo of your receipt with your smartphone and upload the image. Our advanced OCR system powered by Google Cloud Vision automatically extracts all products, prices, and details — even from crumpled or tilted receipts. The processing takes just a few seconds.

Very fast! PDF receipts are processed almost instantly (under 1 second). Photo receipts are processed via Google Cloud Vision in just 1-2 seconds. You'll see a live preview of the extracted data before confirming the import.

Our system shows you a preview of the extracted data before importing, so you can verify everything looks correct. If OCR quality is low, we automatically switch to our most accurate recognition engine. In rare cases where text can't be extracted, you'll see a clear error message.

Yes! KassenBonBon has a 4-layer duplicate detection system: file hash matching, business logic comparison (date + store + total), fuzzy matching, and confidence scoring. You'll be warned before accidentally importing the same receipt twice, and you can compare them side by side.

We support PDF files (from online retailers like REWE) and image files (PNG, JPG, JPEG) from phone photos. Files up to 10MB are accepted, and you can upload multiple files at once.

Yes! Simply forward your receipt emails to bon@kassenbonbon.app or bons@kassenbonbon.app. The receipt will be automatically imported within about 5 seconds. Perfect for quickly adding receipts directly from your inbox!

You can forward receipts to either bon@kassenbonbon.app or bons@kassenbonbon.app. Both addresses work the same way. Only PDF and image attachments are processed — the system automatically filters and imports your receipts.

Very fast! Once you forward your receipt email, it's processed within about 5 seconds. You'll see it appear in your dashboard automatically — with the same duplicate detection and quality processing as manual uploads.

Yes! You can delete individual items from a purchase, delete an entire purchase, or batch-select and delete multiple purchases at once. All deletions include an undo option via a toast notification, so you can restore accidentally deleted data within a few seconds.

Your dashboard is the command center for your shopping data. It features a Spending Pulse hero showing this month's total with month-over-month trends, interactive spending and category charts, recent purchases, price change alerts, and quick-access links to all features.

Go to Settings and set your monthly budget amount. The dashboard will then show a color-coded progress bar — green when you're within budget, amber when approaching the limit, and red when over. You'll see exactly how much you've spent and how much remains.

The dashboard automatically tracks price changes for your frequently purchased items. When a product's price changes by 5% or more, it appears in the Price Alerts section with the old price, new price, and percentage change — so you always know about significant price movements.

Yes! The dashboard has period selector buttons (1 Month, 3 Months, 6 Months, 1 Year, All) that filter both the spending trend chart and category breakdown. This lets you zoom in on recent patterns or see your long-term trends.

The dashboard shows four at-a-glance scores: Health Score (ratio of healthy to treat items), Variety Score (diversity of products and categories), Budget Adherence (current spending vs your historical average), and Freshness Index (fresh vs processed products). Each includes a trend indicator so you can see if you're improving.

You get a comprehensive overview organized in four themed sections: AI-Powered Features (health insights, recipes, substitutions, meal plan), Spending & Budget (budget forecast, savings tracking, anomaly detection), Shopping Patterns (basket analysis, behavior analysis, brand analytics, nutrition), and Reports (weekly AI summary). Plus a full product catalog with search and filtering.

Products are automatically categorized using our AI-powered categorization system (powered by Google Gemini). It recognizes 11+ categories including Fruits & Vegetables, Dairy, Meat & Fish, Beverages, Bakery, Household, Snacks, Frozen Foods, Canned Goods, Ready Meals, and more. The system learns and improves with each receipt.

Yes! The dashboard shows you interactive charts with your spending trends — weekly, monthly, or custom date ranges. You can instantly see whether you're spending more or less than usual and identify patterns in your shopping behavior.

Yes! You can export your purchase data as CSV from the purchases page or the product catalog. PDF reports are available for spending breakdowns, category analysis, health insights, and more. You can also download a full JSON export of all your data from the Settings page (GDPR data portability).

Anomaly detection automatically flags unusual patterns in your shopping: unexpectedly high or low spending, unusually large or small baskets, significant price spikes or drops, and unusual purchase frequency. Each anomaly shows severity (high/medium/low), the expected vs actual value, and how much it deviates from your normal pattern.

Yes! The Weekly Reports feature generates an AI-powered summary of your past week — total spending, daily averages, category breakdowns, and personalized insights. You can regenerate the report at any time to get the latest analysis.

Yes! The Product Catalog lets you search, filter by category, and browse all products you've ever purchased. Each product shows its category, how often you've bought it, and when you last purchased it. You can also export the full catalog as CSV.

Behavior Analysis examines your shopping patterns over time — when you shop, how often, basket sizes, store preferences, and day-of-week trends. It helps you understand your habits and discover opportunities to optimize your shopping routine.

Brand Analytics shows which brands you buy most frequently and how much you spend on each. See your brand loyalty patterns, compare house brands vs premium brands, and discover how your preferences evolve over time.

Savings Analysis (Pro) tracks your shopping savings and identifies products where you find good deals. It highlights opportunities to save more by comparing your spending patterns against price baselines.

The Analytics hub is organized into four themed sections: AI-Powered Features (health, recipes, substitutions, meal plan), Spending & Budget (budget forecast, savings, anomalies), Shopping Patterns (basket, behavior, brands, nutrition), and Reports (weekly AI summary). Each section has a clear header so you can quickly find what you need.

The barcode scanner lets you scan product barcodes using your device's camera or enter EAN codes manually. It looks up detailed product information including name, brand, Nutri-Score, Eco-Score, full nutrition facts per 100g, and allergen data — all from the Open Food Facts database.

Open the Scanner page from your dashboard. Point your camera at a product barcode and it will be detected automatically. Alternatively, switch to manual entry mode and type the EAN number. The product details will appear instantly.

Yes! After scanning a product, you can link it to an existing purchase item. This enriches your shopping data with nutrition information, enabling detailed Nutri-Score analysis and nutrient breakdowns on the Nutrition Analysis page.

The Nutrition Analysis page aggregates nutrition data from all your scanned products. It shows the Nutri-Score distribution (A through E) across your purchases, average nutrient breakdown (fat, carbs, protein, salt, fiber) per 100g, average calories in kcal, and lists of your most nutritious and most caloric products.

No — scanning is optional and adds extra nutrition detail. The more products you scan, the more complete your nutrition analysis becomes. The Nutrition page shows your current coverage percentage so you can track your progress.

KassenBonBon uses Google Gemini AI to power a full suite of smart features: personalized health & nutrition recommendations, recipe suggestions based on what you buy, product substitution recommendations (healthier/cheaper/eco-friendly alternatives), AI-powered weekly meal planning (Pro), natural language queries, intelligent product categorization, weekly AI report generation, and anomaly detection. All AI features are grouped under the dedicated 'AI Features' section in the sidebar and respond in your preferred language.

Our AI analyzes your recent 90 days of shopping data — what you buy, how often, and in which categories — then generates personalized, actionable health and nutrition tips. Recommendations are refreshed automatically when you upload new receipts, and they're always based on your actual shopping patterns, not generic advice.

Yes! The natural language query feature lets you ask questions in plain English or German, like 'How much did I spend on dairy last month?' or 'What are my most purchased products?' — and you'll get an instant, data-driven answer powered by AI.

Basic AI features like product categorization and natural language queries are available to all users. Advanced AI features — including anomaly detection, basket analysis, nutrition tracking, and weekly AI reports — are exclusive to Pro subscribers (€3.99/month). Pro includes a 14-day free trial so you can try everything risk-free.

The AI automatically responds in your browser's language — currently German and English are fully supported. Just switch the app language and all AI recommendations, queries, and insights will adapt automatically.

The AI analyzes your recent purchases and suggests recipes using ingredients you already buy. You get personalized recipe ideas that match your shopping habits — helping reduce food waste and add variety to your meals.

The AI suggests healthier, cheaper, or more eco-friendly alternatives to products you regularly buy. Recommendations are based on your actual shopping patterns and help you make better choices without drastically changing your habits.

Meal Plan is a Pro feature that generates a personalized weekly meal plan tailored to your shopping habits. The AI considers what you typically buy to create realistic plans — with breakfast, lunch, dinner, and snack suggestions for each day of the week.

All AI features are grouped under the dedicated 'AI Features' section in the sidebar (desktop) or the 'More' menu (mobile). Look for the sparkle badge next to AI items and the crown icon for Pro-only features like Meal Plan.
