Questions about Voxel

Short, plain answers about what Voxel does and what it needs.

What is Voxel?

Voxel is a colour grading app for the Mac that you drive by talking to Claude. You say how the picture should look, by typing or out loud, and Claude builds and adjusts the grade in Voxel's engine, checks where the picture clips, and shows you the result on a clean viewer. You never have to touch a colour wheel or a node.

Do I need to know how to colour grade?

No. You describe what you want in your own words, such as "it feels dark", "make it warm, like the late fifties" or "the bricks are too orange", and Claude picks the tools and makes the changes. It tells you what it did after each step. If you do know grading, you can ask for specific steps by name and it will follow them.

What do I need to run Voxel?

A Mac with Apple Silicon (M1 or later) and your own Claude Code sign-in. Voxel does not run on Intel Macs, Windows or Linux. To talk to it out loud you add your own OpenAI key for the voice; without one you type instead, and everything else works the same.

Does my footage leave my Mac?

Your clips are read and rendered on your Mac, on its graphics chip, and Voxel does not upload them. To judge a grade, Claude looks at rendered frames through your own Claude Code sign-in. With voice on, what you say goes to OpenAI through your own key. The terms you agree to in setup describe what goes to Voxel's own cloud: before-and-after stills and the log of each session.

What can Voxel do to a picture?

Exposure, contrast, colour balance, curves, saturation and hue curves, keys, shapes, and masks that follow people or parts of a scene such as the sky. It measures where the picture clips or leaves the colour range, and names the step responsible. It can compare your shot with a reference still and build a match, copy a grade between clips, and play a whole cut in real time.

What can I export?

Movies in ProRes 422 HQ, ProRes 4444 or H.264, either one graded clip or a whole cut as one movie, and LUT files of a grade to use in other software. Your original clips are never changed; Voxel writes new files.

Can a client watch while I grade?

Yes. The client viewer is a separate window that shows only the graded picture and a small timecode, with no menus, nodes or chat. Put it on a second screen for whoever is watching over your shoulder, and the picture updates as Claude changes the grade.

How much does Voxel cost?

The Voxel app is free to use with your own Claude sign-in and, for voice, your own OpenAI key. A hosted plan, where we supply the AI and the voice and you pay by the hour you talk, is being built. Its price is not set yet, and this page will say when it is.

Is Voxel open source?

No. Voxel is all rights reserved. You can download and use the signed app, but its source code is not published and you may not copy or redistribute it. The libraries it bundles keep their own licences, and their licence texts ship inside the app.

Is the download safe?

Every installer on download.voxelcolor.com is signed with Voxel's Apple Developer ID and notarized by Apple, so your Mac checks it before it opens. The site sets no cookies and counts visits without knowing who anyone is.
