WHY 321 DOWNLOADER
Save the videos you need, then use audio and scripts right away in one browser extension. Fast-Track, Scouter, and STT make this possible.
HOW 321 WORKS
Find media more accurately, save more reliably, and use what you saved in more ways. Fast-Track, Scouter, Stream, and STT complete the 321 Downloader experience.
Fast-Track
Automatically collect video signals detected on a webpage and show download options in multiple qualities.
Those options help you save the quality you want more reliably, even when the network is not ideal.
Scouter
If Fast-Track scans a page broadly, Scouter lets you aim at the video area you care about.
Useful when several videos are detected at once and you need only one of them.
Stream
Use Stream when a typical source is hard to obtain.
It records playback in real time, so you wait as long as the video plays. It is a fallback for cases other methods cannot save.
STT
When you need a transcript, generate it in 321 Downloader without installing another program.
Turn what you watch and hear into text you can read and organize immediately.
Collect reference clips and come back to them later.
Keep campaign and reference videos in one place.
Save the files you will actually reuse, not another watch-later list.
Read a script to review and organize video content faster.
FAQ
See what makes it different, where it works, what quality you can get, whether it handles multiple files, whether it can create scripts, and which plan to start with.
321 Downloader is a light, easy browser extension that can handle several jobs at once.
The biggest difference is one connected flow: install, collect, download, and script.
Official support covers YouTube, Instagram, Facebook, TikTok, Douyin, and Xiaohongshu (RedNote). Other sites may work when media is detected, but not every website is guaranteed. DRM-protected video cannot be saved.
Yes. When a detected quality list includes high-quality options such as 1080p, you can choose the quality you want and save it. Available quality can still vary by the original video, how the site delivers it, and what is detected. Even when playback looks low-quality, a higher-quality download option is sometimes detected — that is one of the advantages you can try for yourself.
Yes. You can select several items from the detected download-chip list and download them at the same time. Your plan may limit how many downloads can run together. Actual speed depends on file size, site response, network conditions, and your PC.
Yes. Pro can create a script with STT. You can start Create Script from a finished download, and use the result as TXT or SRT. STT is not included on Free or Plus.
If you are just starting, begin free and check that detection and download work for you. Choose Plus if you download often or want less waiting, and Pro if you also need scripts. See Pricing for counts and prices.
Install 321 Downloader in Chrome, Edge, or Firefox, and save the videos you want as video, audio, or a script.
