Open Source Python Video Converters

AppGrabbit is a Windows 10/11 app that downloads, transcribes and converts videos on your own computer. Paste a link from YouTube (videos, Shorts, playlists, Mixes), TikTok, Instagram, Facebook, X, Pinterest, Twitch or SoundCloud and the file lands in your downloads folder in the quality you pick, up to 4K. Turn any video into a clean .txt with a prompt on top for ChatGPT, Claude or Gemini: with captions it is instant; without them, or from your own recording (a class, a meeting, a voice note), it is transcribed on your PC with Whisper, nothing uploaded. Cut exact clips, grab thumbnails, follow channels, and convert to MP4, MP3, WAV, ProRes 422 HQ or DNxHR HQ for Premiere and DaVinci Resolve. No account, no ads. **Free plan:** 5 credits a month (a credit is one video, one batch of up to 10 links, one transcript or one converted file); when you hit 0 you can claim 1 more every 48 hours. Thumbnails, Watch and the Library are free with no cap. **Pro:** USD 8.99 a month, cancel anytime
