Hey Product Hunt! I built Rack Sabbath because I was tired of Scrabble GO charging real money for basic strategy tools. Word Radar costs $5+ for credits, Tile Shuffle costs more, and ain't nobody paying for that. So I built a free alternative. Upload a screenshot, Gemini Vision AI reads the board, and a trie based solver finds every legal play ranked by score. It runs entirely in your browser, nothing is stored on any server. The tech journey was wild to say the least. It started with Tesseract.js (60% accuracy), tried ONNX template matching, and finally landed on whole board AI recognition at 85%+. The solver evaluates premium squares, cross-words, and blank tiles. Would love your feedback. Is there a feature you'd want to see next? Multiplayer tracking? Score history? Let me know!
