Extraction Lab

Extraction Lab is a professional-grade coffee companion designed for enthusiasts who care about every variable — from bean origin to extraction yield.

AI-Powered Coffee Intelligence

Instantly digitize your coffee bags using multi-tier AI extraction: • Cloud Vision: Anthropic Claude or OpenAI GPT parse labels in seconds with near-perfect accuracy. • Local AI (Gemma): On-device intelligence using the Gemma model and MLX framework — no data ever leaves your phone. • Rule-Based Fallback: Robust pattern matching for offline use. • Hallucination Guard: Automated cross-verification between AI output and raw OCR ensures data integrity.

Precision Brewing Tools

• Guided Brewing: A 3-phase coordinator — Setup, Live Timer, Detailed Log — walks you through every extraction step by step. • Cold Brew Tracking: Start a cold brew and let it run. Background aging timer with push notifications tells you exactly when your brew is ready. • Draft Recovery: In-progress brews auto-save. Close the app, come back later, pick up where you left off. • Recipe Templates: Build custom brewing recipes with step sequences and automatic weight proportions. • Ratio Calculator: Instant dose-to-water calculations for any brew method.

Ecosystem Integration

• Live Activities: Monitor active brews on your Dynamic Island and Lock Screen without opening the app. • Apple Watch: Timer mirroring lets you track brews hands-free from your wrist.

Organized Lab Management

• Workspaces: Create separate environments for Home, Office, or Roastery. Full data isolation between labs. • Bag Tracker: Visual remaining-weight tracking with manual weight adjustments and low-stock alerts. • Freshness Monitoring: Automated roast-age tracking with optimal brew-window indicators and peak-freshness notifications. • Coffee Library: Rich bean catalog with origin data, roast level, and full extraction history per bag.

Analytics & Insights

• Sensory Profiling: Map every brew on a 5-axis taste profile — Acidity, Sweetness, Body, Finish, Balance. • Extraction Metrics: TDS tracking with auto-calculated Extraction Yield and built-in quality assessment. • Origin Heatmap: Visualize your global coffee journey across an interactive world map. • Brew Trends: Charts for rating trends, method frequency, and extraction consistency over time.

Privacy & Sync

• All data syncs seamlessly across your devices via iCloud. • Local AI mode keeps everything on-device. Your data never touches a third-party server unless you choose Cloud Vision. • Full JSON export and backup for your entire library.

Extraction Lab is built for the coffee professional, the home enthusiast, and anyone who wants to turn great coffee into a repeatable craft.
