Colourlab AI Alternative: Browser-Based Color Grading | Leumos AI

The most accessible Colourlab AI alternative is Leumos AI — a browser-based color grading tool now in closed beta, where Colourlab is a desktop install starting at $299 for the Ai 3 Creator perpetual licence. Both use AI to match shots and apply looks, but Leumos runs in Chrome on any laptop, while Colourlab wants a workstation-class machine and an NLE plugin slot to do its best work. It runs on Windows as well as macOS — the constraint is the hardware it expects, not the platform.

I'm Pravit — DaVinci Resolve Certified colourist, BFA in cinematography, and I've graded ad work for Puma and WHSmith plus indie features that hit festivals. I've tested every AI color tool on the shelf — they're ranked in our best Colourlab AI alternatives for 2026 roundup — and Colourlab is the one I respect most for what it actually does. So this isn't a hit piece. It's the honest read from a working colourist who got tired enough of the friction to build a different thing.

Where Colourlab AI wins

Credit where it's due: Colourlab AI was founded by Dado Valentic, who has been grading commercial and broadcast work for decades. That heritage shows up in the product.

The ACES 16-stop pipeline is real. If you're pulling Alexa Mini OpenEXR or RED Komodo R3D into a high-dynamic-range timeline, Colourlab respects every stop. It isn't crushing your highlights to hit a quick match.

The NLE integration is the other big win. Premiere Pro, DaVinci Resolve, Final Cut Pro — Colourlab drops in as a panel, reads your timeline, and ships the grade back as a metadata round-trip rather than baking pixels. For a broadcast assistant editor who lives inside Premiere all day, that's the right shape of tool.

Print Lights and the looks-management workflow lean on language colorists already know from the photochemical era — printer points, density, balance. For a senior colorist transitioning from film, the mental model maps cleanly.

And it's on-device. Your footage doesn't leave the machine. For NDA work, that matters a lot.

If you're a broadcast colorist on a Mac Studio finishing a Netflix-spec episodic, Colourlab is a defensible buy and probably the right tool.

The Colourlab AI trade-off most filmmakers run into

Here's where it gets honest for the rest of us.

I had a short-film DP friend in Mumbai test Colourlab last year. He shoots BMPCC 6K Pro in BRAW, edits on an M2 MacBook Air, and grades wedding-cinematic music videos on the side to keep the lights on. Colourlab's legacy Ai 2 Pro tier is listed at $299 a year, and the current Ai 3 Creator licence at $15 a month. The subscription he could just about carry; the Mac Studio it wants underneath it was the number that stopped him.

That's not Colourlab being greedy. It's a tool sized for the US broadcast market, priced in dollars, sold to people who write it off as a business expense. The catalog is built for that buyer.

The second snag is the install itself. Colourlab assumes you're sitting at a tuned color workstation — Mac Studio, calibrated reference monitor, the works. If you're a one-person operation grading a short on the same laptop you edit on, the plugin handshake — Colourlab launches, Resolve has to be running, project must be set up the right way, scopes have to be reading the right node — eats half an hour before you've touched a wheel.

For a working DP who shot the thing yesterday and is delivering Monday, that overhead is the actual problem. You don't want a broadcast pipeline. You want shot-match, a base look, a few primary tweaks, and an export.

How Leumos AI handles this differently

I'm building Leumos AI for the colourist-shaped problem I kept hitting on indie projects: I need to neutralize 80 shots, apply a base look, fine-tune the hero shots, and get out. Node soup in Resolve takes a day. A heavy desktop tool with plugin handshakes takes most of an afternoon. Both options waste the time I'd rather spend on the actual creative grade.

Leumos AI will run entirely in the browser. No install. Chrome on a MacBook Air, Chrome on a Windows laptop, Chrome on a borrowed machine at a hotel during a festival run — same tool, same project link.

A few of the features Leumos will ship with at launch:

• Reference Image Grading — drop a still from a film you're chasing (a Roger Deakins frame from 1917, a Bradford Young night exterior, a Hoyte van Hoytema interior) and Leumos will pull the color science of that reference onto your shot.
• Match All — pick one hero shot, neutralize it, and Match All will propagate the equalization pass across the rest of the scene using the same AI shot matching approach under the hood. This is where the mechanical time goes.
• AI Scene Cut Detection — your timeline gets split into scenes automatically, with a Manual Cut Tool for the edge cases the AI mis-reads.
• Input Color Space LUT — tell Leumos you shot S-Log3 on an FX3 or C-Log3 on a Canon C70 and the source transform handles linearization before anything else touches it. BMDFilm and ARRI LogC are supported too.
• Preset LUT Library for the base look, Manual Primaries for wheel and curve adjustments after.

What Leumos will not be, on day one: an ACES 16-stop broadcast finishing tool. No node trees, no Print Lights, no plugin handshake into Premiere. That's deliberate. If you're finishing a series for Netflix, stay in Resolve or use Colourlab. If you're a cinematic storyteller cutting a music video, a short, a brand film, or a wedding reel — Leumos will be the faster path.

Which one should YOU pick?

Pick honestly, not aspirationally:

• Broadcast or episodic finishing → Colourlab. The ACES pipeline and NLE round-trip are built for this.
• Pro colorist on Mac Studio with NDA footage → Colourlab. On-device matters; the price is a write-off.
• Solo videographer or wedding cinematographer → Leumos AI when it launches — see our Colourlab AI alternative for wedding work for the genre-specific breakdown. Browser-based, no install, no GPU.
• Indie filmmaker with a short on a laptop → Leumos AI. You need shot-match and a look, not a 16-stop pipeline.
• Pro colorist who already owns Resolve and just wants to skip the equalization grind → Leumos AI as a pre-grade tool, then take the result into Resolve for the creative pass. The AI is approximate, but it takes the equalization stage off your hands.
• Filmmaker outside the US who can't justify a workstation → Leumos AI. Browser-based, nothing to install.

Price comparison

Colourlab AI (from Colourlab's pricing page, as of August 2026): Colourlab Ai 3 Creator at $15/month, $150/year, or $299 as a perpetual licence. Pro and Studio sit above that as annual subscriptions; Colourlab publishes no perpetual price for them and routes perpetual Pro buyers to B&H Photo as its exclusive reseller. The same page lists Ai 3 as running on Mac OS 13 or later and Windows 10 or later; only the legacy Ai 2 line is macOS-only. The practical constraint is the workstation it expects underneath, not the operating system.

Leumos AI: pricing has not been announced.

The only perpetual licence Colourlab prices on its own site is the Ai 3 Creator one at $299, and you still need the Mac Studio underneath. Leumos pricing has not been announced. Two different shapes of tool for two different buyers.

Frequently asked questions

Is Leumos AI available to use right now?

Not yet — Leumos AI is in closed beta. Right now the site is a closed-beta early-access page with a waitlist form. The first 500 signups lock in 50% off for life. If you're researching Colourlab AI alternatives because you want a browser-based option, joining the early-access list locks in the launch discount and puts you in the queue for first access once upload, grade, and export open up. No card required at signup; the discount applies when subscriptions go live.

Can Leumos AI grade log footage like Colourlab AI does?

At launch, Leumos AI will accept common professional uploads. The Input Color Space LUT handles the source transform for log formats — S-Log3 from a Sony FX3, C-Log3 from a Canon C70, V-Log from Panasonic, ARRI LogC from an Alexa, BMDFilm from BMPCC bodies. Colourlab's edge is the on-device 16-stop ACES pipeline for true RAW finishing on a tuned workstation. Leumos is sized for the cinematic storyteller stage of the workflow, not broadcast-spec RAW finishing. Different jobs, different tools, picked honestly.

Does Leumos AI have a Premiere or DaVinci Resolve plugin like Colourlab AI?

No, and that's intentional at the MVP. Colourlab's NLE plugins are excellent if your workflow lives inside Premiere or Resolve all day. Leumos AI will be a standalone browser app — you upload, grade, and export. The result comes out as a baked file you can drop into Resolve as a reference on your timeline. For colorists who want the AI equalization pass without leaving Resolve, Leumos won't be that on day one. For filmmakers who want a faster, lighter, browser-based path that doesn't require a desktop install, it will be.

Will Leumos AI handle ACES like Colourlab AI?

Not at launch. Colourlab AI's ACES 16-stop pipeline is one of the strongest in the category and is the right pick for broadcast and episodic finishing, where every stop of dynamic range matters. The Leumos AI MVP will handle Rec.709 delivery and log-to-display transforms via the Input Color Space LUT for cinematic web, social, and festival-spec delivery. If your finishing target is Dolby Vision or HDR10 broadcast, Colourlab paired with Resolve is the honest answer. If it's a music video, a brand film, or a short heading to festivals or YouTube, Leumos will be enough for the grade.

Is Colourlab AI worth $299 over Leumos AI?

Depends entirely on the work. If you're a senior colorist finishing broadcast or episodic content with NDA footage on a Mac Studio, $299 for the Ai 3 Creator perpetual licence is a reasonable buy — Colourlab's ACES pipeline, on-device processing, and NLE round-trip are sized for exactly that buyer. If you're a solo videographer, indie DP, or cinematic storyteller working on a laptop and grading three to six projects a month, Leumos AI is being built to do the equalization and look work you actually need without a workstation under the desk. Match the tool to the job, not the brand.
