Frequently asked questions

Luttie is a browser-based color grading and LUT creator. Build a grade with RGB curves, color wheels, and HSL secondaries, put your image through a film engine that models negative and print stocks, or generate a grade from a text prompt with AI Grade — then export it as a .cube or .3dl LUT that works in DaVinci Resolve, Premiere Pro, Final Cut Pro, and CapCut. There's nothing to install.

A film emulation stage in the editor: light goes through a colour negative and then a print (or a scanner), modelled from film's characteristic curves rather than RGB sliders. Pick one of five negatives and two prints, set exposure and printer lights, and it works on photos, phone video and camera log (S-Log3, C-Log3, N-Log, Apple Log, Apple Log 2, DJI D-Log). Grading with it is free; exporting the look as a LUT is part of Pro. The stocks are inspired by real films, not measured copies of them.

Yes. The editor itself is free. Grade footage, work with curves and color wheels, and export watermarked images with a free account. Pro removes the watermark and unlocks AI Grade, full-resolution LUT export, RAW file support, and film effects like grain, halation, and bloom. See the full breakdown on the pricing page.

No install required! Luttie runs entirely in your browser. Your images and video are processed on your device using WebGL/WebGPU rather than uploaded to a server, which is also why the editor stays fast on large RAW and video files.

Standard .cube files at 17pt or 33pt, and .3dl for Autodesk Flame, Lustre, and legacy Avid workflows. Pro accounts can also export a LUT pack — the same grade bundled as three .cube files at 50%, 75%, and 100% intensity in a single .zip.

Yes — RAW support (Pro) lets you grade directly from camera RAW files rather than a pre-processed JPEG, so you're working with the full dynamic range the sensor captured before any in-camera color decisions are baked in.

AI Grade turns a written description — or a reference photo — into a starting color grade, which you can then fine-tune with curves, wheels, and HSL. It's a starting point for the look, not a replacement for the manual controls.

Yes. Every Pro plan can be used for commercial, freelance, and client work — real estate, product and e-commerce photography, food and restaurant shoots, automotive listings, and more. There's no separate commercial licence to buy and no per-seat limit for a solo operator.

The week pass is a one-time, non-recurring 7 days of Pro — a good fit if you have one shoot or one project to grade. Monthly is a subscription you can cancel anytime. Lifetime is a one-time payment for Pro access forever, including future updates, with no recurring billing. Full pricing and current rates are on the pricing page.

Refunds depend on usage. If you bought Pro and haven't used it — no LUT exports, no AI grades, no video exports — reach out via the contact form on the homepage and you'll get a full refund, whichever plan you're on. Once you've actually used Luttie, a refund generally isn't possible: AI Grade and video export cost real money to run every time they're used, and Luttie is a one-person operation that can't absorb both the compute and a reversed payment. Cancelling a monthly subscription is a separate thing and always available from your account settings — you keep Pro until the period you've paid for ends.

Checkout accepts cards, PayPal, and Apple/Google Pay — whichever of them your country, browser, and device support will appear as an option, and prices are shown and charged in your local currency where available. If none of those work for you, reach out via the contact form on the homepage.

Yes — Luttie has an MCP server that lets Claude Code, Claude Desktop, ChatGPT, and Codex CLI list LUT packs, generate an AI color grade from a prompt, and apply a LUT to an image, all over MCP. See the MCP page for setup.

Any NLE or grading tool that reads standard .cube or .3dl LUTs — DaVinci Resolve, Premiere Pro (via Lumetri Color), Final Cut Pro, CapCut, Avid, and Autodesk Flame/Lustre for .3dl. Drop the file in like any other LUT; nothing Luttie-specific is required to use it.
