The tools colorists actually use.
AI-assisted grading, film simulation, and the standard professional colour controls — all in one browser tab.
AI Grade
Describe a cinematic look in plain English and get three ready-to-export .cube LUTs in seconds. The AI reads your image and grades from where you are.
Learn more →Film Effects
Grain, halation, and bloom — the three optical effects that separate a colour grade from a film look. Luminosity-blended, real-time, in the browser.
Learn more →RGB Curves
Fine-tune luminance and individual colour channels with the same curve workflow used in DaVinci Resolve and Premiere Pro — without opening either.
Learn more →Color Wheels
Shadow, midtone, and highlight wheels give you a complete three-way colour grading pipeline. Bring life to flat or log footage with precise tonal control.
Learn more →HSL Secondaries
Sample any colour with the eyedropper, then isolate and shift just that range. Essential for selective colour corrections and skin tone work.
Learn more →RAW Editor
Decode CR2, ARW, NEF, DNG, and RAF files directly in the browser. Grade RAW footage and export a .cube LUT without any desktop software.
Learn more →Your grade, ready for any edit.
Export as a .cube LUT — the universal format supported by every major NLE. Apply the same grade to your entire timeline in one click.

Color grading — common questions
What is color grading?
Color grading is the process of adjusting the colours, contrast, and tone of a video or photo to create a specific visual style or mood. It goes beyond basic exposure correction (color correction) to establish a deliberate aesthetic — like the warm teal-and-orange look of Hollywood films, or the desaturated matte finish of documentary footage. Color grading is done using tools like RGB curves, color wheels, and LUTs.
Do I need DaVinci Resolve for color grading?
No. DaVinci Resolve is the industry standard for professional color grading, but it's a 2GB+ download with a steep learning curve. Luttie runs entirely in your browser with the same core tools — RGB curves, color wheels, HSL secondaries, and LUT export — with no installation required. For most video editors and photographers, Luttie covers the full grading workflow.
What is a LUT in color grading?
A LUT (Look-Up Table) is a file that maps input colours to output colours, effectively encoding a colour grade. .cube is the most common format, supported by DaVinci Resolve, Premiere Pro, Final Cut Pro, and CapCut. You build a grade, export it as a .cube LUT, and apply it to your entire timeline in one click. Luttie exports .cube and .3dl LUT files.
Can I color grade RAW files online?
Yes — Luttie decodes RAW files (CR2, ARW, NEF, DNG, RAF) directly in the browser using WebAssembly. No upload to a server, no desktop software needed. Load your RAW file, apply a grade, and export a .cube LUT for use in your NLE.
What is AI color grading?
AI color grading uses a language model to generate color grading parameters from a text description. In Luttie, you type a prompt like 'warm cinematic with teal shadows' and get three ready-to-export .cube LUTs in seconds. The AI reads your image and adjusts the grade to complement what's already there rather than overprocessing.
How do film effects like grain and halation work in color grading?
Film grain, halation, and bloom are optical effects that digital cameras don't produce natively. Grain adds luminosity-blended texture (strongest in midtones, fading at shadows and highlights). Halation creates a warm red-orange glow around bright areas, caused by light reflecting inside the film base. Bloom softens highlights the way old lenses diffuse bright sources. Together they make digital footage read as film. In Luttie these run in real-time using WebGL.
How do I color grade a video for free?
Open Luttie, upload a frame from your video (or extract one directly from an MP4/MOV/WebM file), apply your grade using the curves, color wheels, and basic correction tools, then export a .cube LUT. Apply the LUT to your video timeline in DaVinci Resolve, Premiere Pro, or Final Cut Pro. The entire grading workflow is free — LUT export requires a Pro subscription.
