Mocai

Overview

Mocai converts a single video into markerless body motion, a mesh, and a 127-joint skeleton. It best suits creators who want to bring recorded movement into a 3D or game-development workflow; it is a poor fit for anyone who needs real-time capture.

Its mix of editor plugins, file exports, and API access makes it flexible, while footage quotas and short clip limits constrain how much work each plan can handle.

Key features

Capture and tracking

The maker says footage from any single camera, including a phone, works without markers, a suit, or calibration. Mocai tracks 70 keypoints per performer, from pelvis to fingertips, and supports finger articulation, hand tracking, multi-person capture, root motion, floor grounding, occlusion repair, adjustable smoothing, and synchronized footage review. These controls support detailed video-based animation workflows, but they do not make Mocai a real-time capture tool.

Exports, integrations, and automation

Exports include FBX, GLB, BVH, USD, and raw keypoints, with optional retargets to Mixamo, UE5 Manny, and MetaHuman rigs. Free plugins for Blender, Unity, Maya, and Unreal Engine let users upload clips and import takes from those editors. That breadth is useful when a pipeline spans different tools, though the monthly footage allowance is shared between the portal and API and uploads pause when it runs out.

The public API supports uploads and webhooks, and an MCP server lets AI agents manage takes and exports. Two-step API uploads support files up to 2 GB; inline multipart uploads stay under about 30 MB. Customers own their footage and reconstructions, uploads are not used to train machine-learning models, and stored takes are deleted after the plan’s retention period. The maker says data is encrypted in transit and at rest, stored content uses short-lived signed URLs, and internal access is limited to operational needs.

Pricing

Mocai is freemium, with paid plans starting at $10 a month. Each plan includes downloads in all formats and public API and webhook access, so the main differences are footage volume, clip length, performer count, processing priority, and retention.

The free plan is useful for short, single-person clips, but one minute monthly and 7-day retention leave little room for repeated or longer projects. Basic raises the allowance and performer cap for regular use, while Pro is better suited to teams or creators handling more footage and longer clips. Enterprise is the route for custom usage limits or integrations.

Platforms

Mocai supports web, API, Android, iOS, Linux, macOS, Windows, and self-hosted use. Its named editor plugins cover Blender, Maya, Unity, and Unreal Engine.

Who it's for

Mocai is aimed at people working with Blender, Maya, Unity, Unreal, or their own tools who can capture movement as video and want exports or API-driven workflows. It is less suitable for real-time production or projects that routinely exceed the plan’s clip and monthly footage caps.

Pros and cons

• Pros: Single-camera capture without markers, suits, or calibration lowers setup demands.
• Pros: Multiple export formats, optional rig retargets, and plugins for four major 3D and game tools support varied pipelines.
• Pros: API uploads, webhooks, and MCP server support both direct integration and agent-managed workflows.
• Cons: It is not real-time capture, so it cannot serve workflows that require live motion input.
• Cons: Monthly footage is shared between portal and API, and new uploads stop at the allowance limit.
• Cons: Free use is capped at one minute monthly, 15-second clips, one performer, and 7-day retention.

Alternatives

Choose Move AI if its free offer of 30 credits that do not expire and videos up to 30 seconds better fits occasional short captures. XR Animator is a free alternative. Animaze is another freemium option, with a Plus plan at $3.99 a month billed $47.88/year shown. FreeMoCap may suit users seeking software with no subscriptions, licenses, or hidden fees. mimem.ai offers a free plan with 50 tokens daily, 2 GB storage, and three cameras, but only three monthly FBX exports and retargeting preview. Rokoko Studio offers a free Starter plan with 30 seconds per month of Vision AI video processing, five Studio imports per month, and one month of cloud storage. Webcam Motion Capture offers free access to try all tracking features. AIMoCap is another freemium option.

Verdict

Mocai is a strong fit for creators who need to turn recorded movement into reusable motion data across common 3D tools, especially when API access or multiple export formats matter. Its single-camera premise and broad pipeline support are compelling; look elsewhere if you need real-time capture or routinely process more footage than its monthly caps allow.
