What is ComeCut?

ComeCut (「来剪」) is a free, lightweight, AI-assisted video editing suite that runs in the browser and as a Windows desktop application, built for creators who want a CapCut-like editor without accounts, fees, or cloud uploads.

What it is

ComeCut is an open-source video editing suite licensed under AGPL-3.0, written primarily in HTML, and distributed for the web and for desktop. Its feature set is inspired by editors such as CapCut, and it bundles an AI assistant, native Python plugin extension, ComfyUI workflow integration, subtitle tooling, and generative image and video models inside one editor. The homepage is https://juntaosun.github.io/ComeCut/.

The concrete problem it solves is the cost, account requirement, and data handling of mainstream editors in the same space. ComeCut states that it is completely free with unlimited usage, requires no registration so work can start immediately, and processes media through fully localized processing so data stays with the user. It lives in the browser and desktop ecosystem, and it targets the editing workflow that would otherwise send users to CapCut or Jianying (剪映), both of which appear in the project's topic list. The README frames the goal as a free, scalable ecosystem built on the open-source community.

Key capabilities

  • ComfyUI workflow support, covering z-image, qwen-edit, klein, and ltx2, with the listed graph models Z-Image, Flux-2-klein-4b/9b, Qwen-Image-Edit-2509/2511, Wan2.1, Wan2.2, and LTX-2.3; the workflow requires simple setup to handle input control.
  • "Nano banana" Google Gemini image generation through the models gemini-2.5-flash-image and gemini-3-pro-image-preview.
  • Web platform ASR that converts audio to text.
  • Integrated one-click cutout with hair-level matting.
  • GIF export for one-click generation of GIFs and emojis.
  • A transition engine with more than 100 transition effects plus custom transition creation, and an effects engine with more than 100 filter effects.
  • An Agent chat AI assistant that can find material, edit, trim or delete clips, adjust volume, modify and translate subtitles, save the project, and generate images and videos through ComfyUI; it supports Gemini and OpenAI protocols, Qwen 3.8, and local Ollama and LM Studio.
  • Native Python plugins: once loaded, a plugin appears in the track right-click menu for Audio, Video, or Image, with a full debugging mechanism; example projects are https://github.com/juntaosun/comecut-example and https://github.com/juntaosun/comecut-qwen3-asr.
  • Smart subtitle translation across SRT, VTT, and LRC formats with dual-language display.

Who uses it and how

  • Browser-based creators who want to begin editing without an account, using the hosted web build directly.
  • Windows desktop users, since the desktop version has been compiled and released for download; the developer build is set to expire automatically after 30 days, so it must be refreshed.
  • ComfyUI users who want generative image and video models inside the editing timeline, with the note that models are downloaded from huggingface.co.
  • Plugin developers extending the editor in Python, debugging through the built-in mechanism, and sharing results with others.
  • Subtitle and audio workflows, where Web ASR produces text and SRT, VTT, or LRC subtitles get translated into multiple languages.

Getting started

The web version runs at https://juntaosun.github.io/ComeCut/, and the compiled Windows desktop version is available for download from the project releases page.

How it compares

CapCut and Jianying (剪映) are the editors named in the README and topic list, and ComeCut positions itself as the free alternative to them. Against those products, ComeCut is licensed AGPL-3.0 rather than proprietary, runs without registration or an account, and keeps processing local, so media is not handed to a vendor's cloud. Its cost model is stated as completely free with unlimited usage and no hidden costs, while generative features are supplied through the user's own ComfyUI workflows, Gemini and OpenAI API access, or local Ollama and LM Studio instances.

When to use it — and when not to

Use it when the priority is a no-account, no-fee editor with local processing, and when there is willingness to configure ComfyUI workflows and pull models from huggingface.co. Because several engines are still described as forthcoming — Agent mode integration in the transition engine, and customization and filter features for the effects engine are under development — anyone needing a finished, fully supported effects pipeline should look elsewhere. The 30-day expiry on the developer desktop build also means desktop users must track new releases, and the README excerpt is partial, so some setup detail must be confirmed from the repository directly.

I'm very pleased that AI assistant capabilities are finally highly integrated into video editing. It can help you find materials, edit, adjust volume, modify subtitles, translate subtitles, and generate images and videos using ComfyUI, all within the Agent chat.

👉 What can this AI assistant do?

  • Translate the current subtitle into English.
  • Find and correct typos in the subtitles.
  • Find music and add it to the track.
  • Create a beautiful girl using ComfyUI.
  • Find a specific subtitle and position it on the timeline.
  • Delete or trim a clip.
  • Add music to the track and adjust the volume to 50%.
  • Save the project.
  • You can delegate anything to it...
  • This is your AI assistant; it can do everything!

AI Assistant: Supports protocols such as Gemini and OpenAI, including Qwen 3.8, as well as local Ollam and LM Studio!

✨ Highly Flexible Python Native Extensions

I'm thrilled that in this update, I've achieved the epic completion of native Python extensibility support. This means that in the future, you'll have access to open-source community plugin support, just like ComfyUI, such as Track Audio to Subtitle ASR (already implemented). You can fully develop and extend your own plugins, allowing you to use the latest models and technologies in your video editor and share them with friends and others, improving your workflow!

  • All plugins come with a full-featured debugging mechanism, making your plugin development smoother!
