## EbSynth

EbSynth was built around a simple, powerful idea: if you can edit one frame of a video, you should be able to edit all of them. You paint or retouch a few keyframes — say, one every dozen or so frames — and EbSynth's propagation engine analyzes the optical flow of the underlying footage to push that stylization across the rest of the timeline. The result is a hand-drawn, painterly, or colorized look with a fraction of the manual labor a traditional frame-by-frame rotoscope would demand.

A detail worth knowing: the core propagation is not a generative model. It is a texture-synthesis algorithm that works only from your own footage and keyframes, so nothing is invented from external training data. There is an optional AI "Generate Image" feature that can create keyframes for you, which artists often use as a starting point before painting corrections.

The modern version runs in the browser as a subscription service. The Free tier includes all core functions with 720p MP4 export, Pro adds 1080p/4K and PNG-with-alpha output, and the Studio plan ships a Windows desktop app so footage never leaves your machines — useful for NDA-bound client work. Typical uses include music videos, hand-drawn animation over live-action performance, digital makeup and cleanup, and colorizing archive footage.

**Pricing & Plans:** Free tier with all core functions and 720p MP4 export; Pro at roughly $20/month for 1080p-4K exports, PNG alpha output and priority processing; Studio at about $200/month per seat with a local Windows desktop app for fully private, offline processing.

- **Keyframe propagation:** Paint a small number of frames and let the engine carry your style across the rest of the clip using optical flow from the source video.
- **Painterly stylization:** Bring a hand-drawn, oil-paint or illustration look to live-action footage — ideal for music videos and animated shorts.
- **Retouch, rotoscope and colorize:** Skip manual tracking for digital makeup, blemish removal, cleanup and colorization of old footage.
- **Optional AI keyframe generation:** Generate a starting keyframe with AI, then correct artifacts by hand and polish with a lighter second pass.
- **Local Studio app:** The Studio plan runs EbSynth entirely on your own Windows machine, so sensitive footage never uploads anywhere.

**Strengths:** Dramatically reduces the manual work of frame-by-frame rotoscoping and stylization; Free tier has no time limit and includes the core engine; Browser-based workflow, with tutorials and documentation aimed at artists; Studio desktop option keeps confidential footage fully offline

**Limitations:** Propagation quality depends heavily on clean footage and careful keyframe placement; Heavy projects need a capable machine and Chrome's memory handling; Advanced output (4K, PNG alpha) sits behind paid subscription tiers

## 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
