# AetherCut > AetherCut is a privacy-first, browser-based AI video editor. Your media never leaves your device — verifiable in Chrome DevTools in 30 seconds. The editor runs entirely client-side via WebCodecs, WebAssembly, and WebGPU. AI features that need cloud inference (Whisper auto-captions, ElevenLabs voiceover, Sora 2 B-roll) are opt-in per feature and disabled in one click via Privacy Mode. AetherCut targets creators, journalists, legal teams, healthcare communicators, and anyone editing footage under an NDA or privacy requirement. It is a Progressive Web App, works offline after install, and exports up to 4K with no watermark on the free tier. Pro is $14.95/month or $129.88/year, with a Lifetime Pro one-time purchase option. ## Core positioning - **Privacy claim is structural, not promised**: AetherCut cannot upload your media because the architecture does not include an upload step. You can verify zero outbound media traffic in the browser's Network tab. - **Full NLE in the browser**: multi-track timeline, keyframe animation, color grading, motion tracking, scene detection, lip-sync, eye-contact correction, background removal, object erasing, AI auto-cut. - **AI features bundled, not metered**: Whisper transcription runs locally via WebGPU. Cloud AI features included in Pro at a flat rate, not per-second pricing. - **No vendor lock-in**: Projects stored in your browser's IndexedDB. Exports are standard MP4 / MOV / WebM. Importable in any other editor. - **20 languages** including Hinglish, Arabic (RTL), Spanish, Japanese, Chinese, German, French, Portuguese, Italian, Korean, and 10 more. ## Comparison pages These are server-rendered HTML pages with side-by-side feature comparison tables and JSON-LD ItemList structured data: - [AetherCut vs CapCut](https://aethercut.app/vs/capcut): Privacy comparison — CapCut uploads to ByteDance servers, AetherCut keeps media in the browser. CapCut Web caps free tier at 1080p; AetherCut free tier is 4K. - [AetherCut vs Clipchamp](https://aethercut.app/vs/clipchamp): Clipchamp uploads to Microsoft Azure. AetherCut is a privacy-first Clipchamp alternative with offline export. - [AetherCut vs Descript](https://aethercut.app/vs/descript): Same transcript-driven editing workflow as Descript, but Whisper runs locally via WebGPU. No audio upload. Flat pricing instead of metered transcription hours. - [AetherCut vs Kapwing](https://aethercut.app/vs/kapwing): Both are browser-based.
