## in3D

in3D is a mobile application built for turning real people into realistic 3D avatars with nothing more than a phone camera. You scan your face and body from a few angles, the app reconstructs a textured 3D model, and you can adjust its look before exporting it for use in games, virtual worlds, social platforms and avatar-driven apps. The company behind it reports the whole capture-to-avatar process completes in under a minute, which is what makes it practical for creators and studios who need many avatars rather than one hero model.

The product now sits inside a wider family from Goodsize Inc., the company that operates in3D. Alongside the in3D mobile app, the same team runs Avaturn.me, a platform that creates game-ready avatars from a single selfie, Avaturn.live for real-time expressive AI avatars that react in live conversation, and Yolk, an AI sales coach for reps. That means in3D remains the consumer-facing scanning app while the sibling products cover developer pipelines, live interaction and business use cases.

The core use cases are metaverse presence, game character creation and any app where users want to represent themselves authentically without a 3D artist. Expect to provide a well-lit scan for the best result, and check licensing terms before shipping an avatar into a commercial product. If you landed on in3d.io expecting the original standalone site, you are now on the corporate page of Goodsize Inc., where in3D is presented as one of four products.

**Pricing & Plans:** Advertised as a freemium product: the in3D app can be downloaded and used with free avatar creation, while additional avatars, higher-fidelity output and platform or SDK access sit in paid tiers and business plans. Exact prices are shown inside the app or via the company's sales contact.

- **Phone-camera capture to 3D model:** Scan yourself from different angles and the pipeline generates a textured 3D head or avatar model automatically.
- **Customizable avatar options:** Adjust the generated avatar's appearance and styling before exporting it to your project.
- **Under-a-minute generation:** Each avatar is produced in well under a minute, so individuals and teams can iterate quickly during production.
- **Exportable for games and apps:** Export the finished avatar for use in metaverse spaces, mobile and PC games, social apps and avatar-driven experiences.
- **Related SDK and platform options:** Advanced teams can plug scanning and avatar generation directly into their own product or game pipeline via the company's developer offerings.

**Strengths:** Creates realistic 3D avatars from an ordinary phone camera, no dedicated scanning rig; Fast generation makes it viable to produce many avatars rather than a single model; Sits alongside Avaturn and Yolk, so teams can scale from consumer app to developer pipeline; Customisation and export options cover games, apps and virtual worlds

## Spline

Spline brings 3D design into the browser so designers, developers and marketers can build interactive 3D without a heavyweight desktop pipeline. The editor covers primitives, booleans and sculpting, plus 3D generation, layered materials, lighting and post-processing. Animation and interaction are handled through states, keyframes, events and physics, and the whole file runs with real-time performance.

A standout feature is agent collaboration: you can connect assistants such as Claude, ChatGPT, Cursor or Codex through Spline MCP so an agent can read and write to the live scene, then hand it back to your team for refinement in the very same file. Because everything the agent produces is a regular Spline object, teammates can select, restyle, animate or undo it by hand at any point.

Publishing targets the modern web and mobile stacks. You can share a link, embed a viewer or export code for web (WebGPU/WebGL), add a native SwiftUI or Metal view for Apple apps, or build for Android with Vulkan and Jetpack Compose. Spline is used for interactive product design, brand and marketing pages, immersive experiences, gamified sites and education.

**Pricing & Plans:** Spline offers a free tier to start building in 3D, with paid plans for individuals and teams and a dedicated Enterprise offering. Exact seat and feature limits per tier are listed on the Spline pricing page.

- **In-browser 3D editor:** Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
- **Materials, lighting and post-processing:** Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
- **Animation and interaction:** Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
- **Agent collaboration over MCP:** Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
- **Ship to web, iOS and Android:** Publish a link, embed a viewer, export code for the web, or create native Apple and Android views and builds.

**Strengths:** Runs entirely in the browser, so there is no heavy install or setup barrier; Real-time collaboration and agent workflows keep designers and developers in one shared file; One scene publishes to web, iOS and Android with platform-native renderers; Broad feature set spanning modeling, materials, animation, physics and interaction

**Limitations:** Advanced 3D work may still require a learning curve for newcomers; Performance and export options depend on the device and platform you target; Team and enterprise capabilities sit behind paid tiers
