Kapwing is a capable cloud editor, but to use it you upload your footage to its servers, where the editing and rendering happen. Supercut takes the opposite approach: your video never leaves your device. Editing runs in the browser through WebAssembly. The AI that plans the edit gets your request, the words said in your clip and its sound levels (both worked out on your device), and a few low-resolution frames only if you turn that on.

Kapwing is cloud-native, so your clips are uploaded and rendered on its servers. Supercut decodes, edits, and exports locally in your browser. Your video files never go over the network, so there is nothing to upload and nothing to wait on. The AI that plans the edit gets your request, the words said in your clip and its sound levels (both worked out on your device), and a few low-resolution frames only if you turn that on.
Kapwing drives editing through a drag-and-drop timeline plus AI tools. With Supercut you describe the edit in plain English, an AI plans it, and a deterministic engine maps it to FFmpeg operations. No timeline scrubbing required.
Because Kapwing renders in the cloud, it needs a connection to process and export. Supercut runs in the browser via WebAssembly, so once the page has loaded you can keep editing offline.
Kapwing lets you start editing but typically asks you to sign up to save work and unlock the full toolset. Supercut lets you edit with every tool and make your first export with no account at all.
Most cloud editors cap free usage around things like export count, video length, resolution, and storage on their servers. Supercut processes locally, so the size of your footage is bounded by your own device, not an upload quota.
Both tools gate unlimited exports behind a paywall, but only Kapwing adds a watermark on the free tier. Supercut puts no watermark on any export: editing is free, the first export is free, and the paid plan gives you unlimited exports, from 4.99 per month billed yearly (59.88 per year), or 9.99 per month monthly, or 79 once for lifetime access. Cancel anytime.
Kapwing is genuinely strong at team workflows. It offers real-time collaborative editing, shared workspaces, a brand kit, and time-stamped comments for review and approval. Its cloud model also gives you cross-device continuity, a broad and mature AI toolset, and a beginner-friendly timeline that students and small teams pick up quickly. If your work centers on collaboration, Kapwing is a solid choice.
