The truly free, and open-source cross-platform CapCut replacement.

## About
Concat is everything you use CapCut for. No watermarks. No paywalls. No subscriptions.
It runs entirely on your machine, powered by a native Rust engine. Install it and start cutting. No account, no setup.
## Highlights
- ๐ซ **No watermarks.** No account. No paywall.
- ๐ **100% local.** Nothing leaves your machine.
- ๐ฌ **Multi-track editing.** Several timelines per project.
- โ๏ธ **Cut fast.** Split, trim, merge, transitions, speed control.
- ๐ฌ **Auto-captions.** Runs on your machine, offline.
- ๐ฃ๏ธ **Text-to-Speech.** Free, local voices.
- ๐๏ธ **Voice filters.** Clean up or play with your sound.
- ๐ **Titles and styled text.**
- ๐ฆ **Templates.** Build an edit once, reuse it.

- ๐ **Twelve languages.** Add one with a single JSON file, see [TRANSLATING.md](TRANSLATING.md).
## Get started
Concat is currently in **Beta version (pre-release)**. **Download** the latest build from [Releases](https://github.com/jub0t/Concat/releases).
**Reporting something:** every run writes a log, and Settings โบ About has the button that opens it along with the one that copies your system information. Attach both to an [issue](https://github.com/jub0t/Concat/issues) and the report arrives with everything it needs. The last ten runs are kept, so yesterday's is still there; nothing is ever sent anywhere on its own.
**Platform support:**
- โ **Windows**
- โ x86_64
- โ **macOS** โ unsigned binaries; run:
`xattr -dr com.apple.quarantine /Applications/Concat.app`
- โ Intel
- โ Silicon

- โ ARM
- โ x86_64
- โ **Android**
- โ Phones
- โ Tablets
- ๐งช **iOS / iPadOS**

**Status:** โ Supported ยท ๐ง Work in progress ยท ๐งช To be tested
**System requirements:**
Concat runs everything on your machine, so the hardware sets the ceiling. The minimum column is what a build will run on at all; the recommended column is what makes 1080p editing feel smooth and keeps 4K exports and captions from being a wait.
| | Minimum | Recommended |
|---|---|---|
| **CPU** | Any 64-bit processor from 2013 or later | 6 cores or more |
| **GPU** | None. Without a usable GPU the window and monitor fall back to the CPU | Any GPU with Metal (macOS), DirectX 12 (Windows) or Vulkan (Linux) |
| **RAM** | **4 GB** | **16 GB** for 4K timelines and the larger caption models |
| **Storage** | **500 MB** for the app and the smallest caption model | **2 GB** for every optional model, plus room for projects and exports |
Optional models download from the settings panel on first use and then never need the network again: auto-captions 78 MB to 488 MB depending on the whisper size you pick, text-to-speech 132 MB or 349 MB, person cutout 15 MB, object cutout 179 MB, and the cutout brush 40 MB.
## How to Contribute
> [!IMPORTANT]
> The best way to contribute is to grab a build from the [Releases](https://github.com/jub0t/Concat/releases) page and use it: find where it breaks, and say where it could be better.
>
> Ready to write code? [CONTRIBUTING.md](./CONTRIBUTING.md) covers setup, the layout of the tree, the checks to run, and how contributions are licensed. Want to write an effect, a filter or a transition instead? [EFFECTS.md](./EFFECTS.md) is the whole of it: a folder, a manifest, and a chain or a shader, loaded from your effects folder while the app runs. Driving Concat from a script, a service or an agent? [docs/](./docs/README.md) is the developer reference for the Concat API and its transports: JSON-RPC, gRPC and MCP. [ROADMAP.MD](./ROADMAP.MD) says where the project is going, and [this Discussion](https://github.com/jub0t/Concat/discussions/3) is where it was announced.
