AetherCut

AetherCut is the privacy-first AI video editor that runs entirely in your browser. Your media never leaves your device — and you can verify it yourself in Chrome DevTools in under 30 seconds. Most "browser" video editors aren't actually private. CapCut uploads to ByteDance servers. Clipchamp uploads to Microsoft Azure. Descript uploads your audio for cloud transcription. Kapwing uploads everything. They all process your footage in their cloud, which means your clips are under their terms of service, their training-data policies, and their data-residency rules. AetherCut is structurally different. The editor is built on standard browser APIs — File API, Canvas, WebCodecs, WebGPU, and WebAssembly. None of these require network access. When you import a clip, the bytes go into your browser's memory and stay there. Open the Network tab in Chrome DevTools and you'll see zero outbound traffic carrying your media. The privacy claim is falsifiable, not promised. WHAT YOU GET • Full multi-track timeline with frame-accurate seek, keyframes, and standard NLE controls • 4K export with no watermark on the free tier • 69+ creative tools and 29+ AI features • AI auto-cut (Magic Reel) that pulls highlights from long-form footage • Whisper auto-captions running locally on your GPU — no audio upload required • Background removal, scene detection, motion tracking, color match, video stabilization — all on-device • AI lip-sync, eye-contact correction, object eraser, and AI Director powered by Claude • Optional cloud AI when you want it: ElevenLabs voiceover, Sora 2 B-roll, AI dubbing — each opt-in per feature • Real-time collaboration via peer-to-peer CRDT (no vendor server holds your project) • Full PWA support: install once, works offline, even on a flight • 20 languages including Hinglish, Arabic (RTL), Japanese, Chinese, Spanish, Portuguese, German, French, Korean, Italian, and more PRIVACY MODE One toggle in the header severs every cloud AI call. With Privacy Mode on, AetherCut becomes a fully offline editor — no outbound network calls of any kind. The on-device AI features keep working normally. For high-security environments where any outbound traffic is a non-starter, Privacy Mode delivers the full editor without a single cloud dependency. WHO IT'S FOR • Creators who don't want their footage feeding into anyone's training data • Journalists working with confidential sources who can't risk third-party uploads • Legal teams reviewing discovery footage that can't leave client privilege • Medical communicators editing patient case studies under HIPAA-equivalent rules • Corporate communications handling unreleased products, M&A material, or NDA work • Anyone who simply doesn't want to upload their videos NO VENDOR LOCK-IN Your projects live in your browser's local storage (IndexedDB). You can export them to a JSON file and import on a different machine. Exports are standard MP4, MOV, and WebM — playable in any video player and editable in any other editor. If AetherCut went away tomorrow, you wouldn't lose access to your work. PRICING • Free tier: full editor, 4K export, no watermark, most AI features included • Pro: $14.95/month or $129.88/year — adds longer projects, advanced AI, priority cloud AI • Lifetime Pro: one-time purchase, no subscription, no recurring billing No account required to start editing. Tap "Try without signing in" to drop straight into the timeline as a guest. VERIFY THE PRIVACY CLAIM YOURSELF Open AetherCut in Chrome. Press F12. Switch to the Network tab. Import a 4K video. Watch zero outbound requests carrying media data. This is the falsifiable privacy claim that no upload-based editor can match. If you've been burned by a "private" cloud editor before, this is the architecture you actually wanted.
