Review a candidate, accept it, render. The clips land in the Clips tab, ready to download.

More screenshots, in both themes, are in docs/screenshots.

The web UI (React) talks to a local FastAPI server on 127.0.0.1. A persistent job queue runs the heavy steps in lanes (GPU, CPU, I/O, network), and a resource governor decides how fast they may run from what you're doing (game in front, fullscreen video, away from the PC). Whisper and the language model never share the GPU. Every step caches its result, so a closed app resumes where it stopped. Details: docs/how-it-works.md.

Tech stack

Layer	Built with
UI	React 18, TypeScript, Vite; 7 locales with a completeness check in CI; dark and light themes; axe-checked accessibility
Server	Python 3.11-3.13, FastAPI + Uvicorn, a persistent multi-lane job queue, a resource governor (psutil, NVML)
Speech	faster-whisper (CUDA / CPU), mlx-whisper (Apple Silicon), a CTC aligner for word timing, sherpa-onnx (laughter, voices)
Analysis	NumPy / SciPy signal scoring, librosa (music mode), OpenCV (facecam), RapidOCR (game HUD)
Language model	Ollama with Qwen 3.5 (4B / 9B, picked from your VRAM), structured JSON output
Video	FFmpeg filter graphs, NVENC / VideoToolbox / QSV / AMF hardware encoding, yt-dlp
Publishing	YouTube Data + Analytics APIs (OAuth + PKCE), TikTok Content Posting API, Instagram Graph API; tokens encrypted with DPAPI / Keychain
Quality	600+ pytest tests on Windows, Ubuntu and macOS; ruff; a Playwright layout check at 9 screen sizes (phone to 1920 px) in 3 languages and both themes; a pixel check that the live preview matches the render
Install	One-click PowerShell (Windows) and shell (macOS) installers, in-app updates via git
