LUTai is a static web application that generates cinematic 3D LUTs (Look Up Tables) from natural language descriptions. It uses the Google Gemini API to translate mood and lighting prompts into precise color grading parameters, including ASC-CDL, white balance, and split toning.

• Text-to-LUT: Describe a look (e.g., "Bleak Russian winter", "Warm golden hour") and the AI generates the color math.
• Real-time Preview: Upload your own reference image to see the grade applied instantly.
• Advanced Color Science: Manipulates exposure, contrast, saturation, temperature, tint, lift, gamma, gain, and split toning.
• Universal Export: Downloads standard .CUBE files compatible with DaVinci Resolve, Adobe Premiere Pro, Final Cut Pro, and OBS.
• Privacy Focused: Runs entirely in the browser. Your images are never uploaded to a server; only the text prompt is sent to the AI.

• Go to Google AI Studio.
• Create a free API Key.
• Paste the key into the LUTai interface when prompted.
• The key is used temporarily within your browser session to fetch parameters.

This project uses modern JavaScript (ES6+) and Canvas APIs. It works best in Chrome, Firefox, Safari, and Edge.
