Blender add-on AI Roto automates rotoscoping masks offline for $14.99

A new Blender add-on named AI Roto sets out to automate rotoscoping, the frame-by-frame mask work that sits behind much of visual effects compositing. According to a post on dev.to, the tool generates and tracks masks for a chosen subject across an entire image sequence, runs entirely on the user's machine, and is priced at $14.99.

The task it replaces

Rotoscoping means isolating a subject from its background in every frame of a shot so it can be composited into new surroundings. Done by hand, it requires tracing and correcting edges frame after frame. The dev.to post puts the cost in perspective: a ten-second clip at 24 frames per second adds up to 240 frames of manual mask painting. Faced with that, artists either pay for dedicated roto software or absorb the hours themselves.

What the add-on does

According to the post, AI Roto works entirely offline inside Blender, with no cloud processing and no server-side subscription checks. Rather than tracing an outline, the user clicks a subject once, and a feature called Forward Pass propagates that selection across the whole sequence, generating masks frame by frame.

For refinement, the add-on uses a pattern familiar from other AI matting tools: left-clicking drops positive points marking what should be kept, while right-clicking drops negative points marking what should be excluded. The tool also supports multiple independent mask layers within a single sequence, and each layer produces its own node in Blender's compositor, so results flow directly into an existing compositing setup rather than a separate application.

The workflow

The described process is straightforward: install the add-on through Preferences > Add-ons > Install from Disk, load the image sequence in the Image Editor, add the same sequence in the Compositor, and open the AI Roto panel. After selecting the subject and running Forward Pass, a Place Roto Points tool lets the user drop positive and negative points for precision. Each layer's roto node can then be pulled into the composite.

Who it is for

The dev.to post lists its intended users: VFX artists compositing shots without green-screen footage, motion designers who need fast subject isolation, indie animators and solo creators without a dedicated roto team, and anyone currently outsourcing the work.

Why it matters

Rotoscoping is a recurring bottleneck in independent VFX, and tools that remove it shift small-studio budgets away from repetitive labor and toward creative work. Two aspects of the announcement stand out. First, the offline design means footage never leaves the artist's machine, which matters for unreleased or contractually protected material. Second, the $14.99 price undercuts the standalone roto software the post references, putting automated matting within reach of hobbyists and solo creators.

There are caveats worth noting. All details come from a single promotional post on dev.to, and it does not specify which AI model the add-on uses, what hardware it requires, or how it handles difficult footage such as motion blur, hair, or overlapping subjects. Buyers will want to test it against their own clips before committing a pipeline to it. Still, if the claims hold up, AI Roto reflects a broader trend: AI-assisted matting migrating from high-end suites and cloud services into cheap, local tools embedded directly in the software artists already use every day.
