How to use Savy

Savy downloads on your own computer through a small app called Savy Helper. Set it up once, then paste links as often as you like.

First time only: set up Savy Helper

Savy Helper works on Windows 10 and 11. It can't run on a phone or tablet.

  1. Download Savy Helper (about 110 MB, a zip file).
  2. Unzip it and keep the folder somewhere permanent, for example C:\Savy Helper. Don't run it from inside the zip.
  3. Open Savy Helper.exe. If Windows says “Windows protected your PC”, the app is just new and not code-signed: click More info, then Run anyway. Nothing opens except a small page confirming it's running.
  4. Come back to Savy. The install card disappears and a small “Savy Helper connected” line shows under the link box. If your browser asks to allow access to apps or devices on your network, choose Allow.

Every time you download

  1. Make sure Savy Helper is running. You'll see “Savy Helper connected” under the link box. If you see the install card instead, open Savy Helper.exe and wait a few seconds.
  2. Copy a video link from YouTube, Instagram, TikTok or another site. Paste it in the box (or press Ctrl+V anywhere on the page) and press Fetch.
  3. Choose Video and a quality, or Audio as MP3, M4A, OPUS or WAV. You can rename the file, trim it, or take the thumbnail or subtitles.
  4. Press the big Download button and wait for it to finish.
  5. When it says Ready to save, click Save file. The file goes to your browser's normal Downloads folder.

Pasting several links, or a playlist, gives you a list: tick what you want and download it all, including as one zip.

Controlling Savy Helper

Open Savy Helper.exe again (or go to http://127.0.0.1:47653/) for its control page:

  • Start with Windows runs it quietly whenever you sign in, so you never have to open it by hand.
  • Quit Savy Helper stops it. The site then shows the install card until you start it again.

Opening it twice never starts a second copy.

Good to know

  • While a download is being made, the file sits in %LOCALAPPDATA%\SavyHelper\tmp and is deleted after an hour. Your saved copy in Downloads is yours to keep. Quitting the helper mid-download cancels it.
  • The download engine (yt-dlp) updates itself. If a new Savy Helper is released, the site shows an Update link.
  • Private, members-only, DRM-protected and some age-restricted videos usually can't be downloaded.

If something goes wrong

Windows blocking the app, the site not finding Savy Helper, a failed download? Fix common problems. The quick ones:

  • “Platform is checking us” or “verify you're not a bot”: the site, often YouTube, is blocking your connection for now. Wait a few minutes and try again.
  • The install card stays after you opened Savy Helper: press Check again, make sure you chose Allow on the browser prompt, and try a hard refresh (Ctrl+Shift+R).
  • A link isn't recognised: make sure it's the page address of one video, then check the supported sites on the home page.
