GoldFinder de AgentJoe

GoldFinder turns Google Maps into a gold prospecting workstation. Open any
▎ river in satellite view and a panel appears with everything you need to
▎ evaluate a location before you ever set foot near the water.
▎
▎ Manual marking tools
▎ Activate a tool and click anywhere on the map to drop a colour-coded marker:
▎ - 🔄 Inner Bend — the calm inner side of a river curve where gold settles
▎ - ✨ Gravel Bank — bright sandbars and gravel bars that trap placer gold
▎ - 🪨 Obstacle — the quiet zone downstream of boulders, islands, or bridge
▎ pillars
▎ - 🌊 Transition — where a fast, narrow channel opens into slower, wider
▎ water
▎ - ⛰️ Near Mountain — upstream elevation means fresher, richer material
▎
▎ Gold probability score
▎ Every marker you place updates a live score bar. The more geological traps
▎ you identify, the higher your confidence rating — from ❌ Unlikely all the
▎ way to 🥇 Excellent.
▎
▎ 30-second quick check
▎ Five yes/no checkboxes let you rapidly assess any spot. Three or more ticked
▎ means it's worth a closer look.
▎
▎ AI satellite scan
▎ Hit the scan button and GoldFinder captures the current satellite view and
▎ sends it to an AI model for analysis. Promising spots are detected
▎ automatically and dropped straight onto the map as markers. Works with:
▎ - Claude.ai subscription (no API key needed)
▎ - Anthropic Claude API key
▎ - OpenAI GPT-4o API key
▎
▎ Enhance View
▎ A one-click filter boosts contrast and reduces saturation so light-coloured
▎ gravel banks stand out against the water.
▎
▎ Gold spotting guide
▎ Built-in accordion guide explains the geology behind each marker type —
▎ useful whether you're a beginner or just need a reminder in the field.
▎
▎ No account required. API keys (if used) are stored locally on your device
▎ and never sent anywhere except the AI provider you choose.
