AetherCut — Privacy-First AI Video Editor

AetherCut is a browser-based AI video editor for creators, agencies, and enterprises who refuse surveillance. Every edit runs locally on your device — your footage never uploads to a server. Full 4K export, 82 tools, 35 AI features, and nothing streams to the cloud. Verifiable in your browser's DevTools Network tab.

Private video editing in your browser

Unlike CapCut, Descript, or Runway, AetherCut does local video editing — your files stay on your device from first cut to final export. Journalists, lawyers, medical educators, and creators handling NDA material can legally edit sensitive footage without a single byte uploading. The privacy promise is architectural, not marketing — open DevTools while you edit and the Network tab stays empty.

How it works

AetherCut runs on WebCodecs and WebGPU — the same browser primitives Chrome, Firefox, Safari, and Edge use for hardware-accelerated video. Timeline editing, cuts, transitions, keyframes, and 4K H.264 export all happen client-side at native speed. Load AetherCut once, cache the PWA, and it works offline forever.

AI features without the upload

AetherCut ships 35 AI features that either run entirely in-browser or route through privacy-respecting APIs: AI voice cleanup, eye contact correction, magic mask, object erase, transcript-driven cuts, silence removal, auto captions in 20 languages, Sora 2 b-roll generation, AI upscale, and background removal. When an AI feature needs a server round-trip, only the audio/frame slice needed for that specific tool is sent — never your full project.

Who AetherCut is for

Solo creators posting to YouTube, TikTok, and Instagram. SMB marketing teams doing weekly social video. Privacy-first professionals — legal, medical, journalism, HR training — who cannot legally upload footage. Emerging-market creators on Android phones and Chromebooks who don't own a $1,500 laptop. AetherCut is the only private video editing software that serves all four.

Why nothing uploads

CapCut's parent (Bytedance) grants itself a worldwide license to your uploaded footage. Descript stores transcripts indefinitely. Adobe Creative Cloud syncs your projects to their servers. AetherCut architected around all three risks: zero source-file uploads, zero transcript retention, zero project sync. If you delete your browser data, we have no record you existed.

Frequently asked questions

Does AetherCut really keep my video local?

Yes. Open DevTools → Network tab → start editing. You'll see zero video bytes leaving your browser. Only static assets (fonts, JS, CSS) and small AI feature slices when you explicitly invoke them.

Do I need to install anything?

No. AetherCut runs in any modern browser. Installable as a PWA on iOS and a TWA on Android via Google Play, but never required.

What's the pricing?

Free tier ships 20 tools with full 4K export and no watermark. Founder Pro is $14.95/month for the first 100 subscribers (lifetime price lock), unlocking all 82 tools and 35 AI features. See Founder pricing details.

What formats does AetherCut support?

Is my data private?

Yes — read the privacy policy for the full architecture. Short version: your source files never leave your device.
