Why Circle Downloader
Circle.so has no native download button. Tella recordings expire. Loom auto-deletes older videos on free plans. Course platforms embed videos from multiple sources with no unified download option.
Circle Downloader handles all of them in one extension — detecting videos across 7+ platforms and converting HLS/DASH streams to standard MP4 files directly in your browser. Open a lesson or post with a video, click the extension icon, pick your quality, and it saves as MP4.
Features
- Multi-platform detection — Circle.so, Tella.tv, Loom.com, YouTube, Vimeo, Wistia, and generic embedded players
- Finds hidden embeds — detects players buried inside Circle.so web components
- Stream-to-MP4 conversion — converts HLS/DASH streaming video to downloadable MP4 in-browser
- Quality selector — all available resolutions per platform with bitrate and estimated file size
- Concurrent downloads — up to 3 simultaneous downloads with real-time progress, speed, and cancel
- Batch download queue — add multiple lessons and process them automatically
- YouTube URL display — one-click yt-dlp copy for Mac and Windows
- Right-click context menu — quick downloads without opening the popup
- Auto-organized storage — saves to a Circle Downloader subfolder in Downloads
- Desktop notifications — alerts when downloads complete or fail
- Original quality preserved — no re-encoding, no watermarks, no quality loss
- Privacy-first — all processing on-device, zero tracking, no data sent to external servers
- 100% privacy-friendly — no tracking or data collection
- 1-on-1 support via our community

Downloading Member-Only Content
The Circle Downloader extension respects your existing Circle login and permissions. If you can view a post in your community — whether it's public, member-only, or restricted — the extension can download it using your authentication.
Key Points:
- Your existing Circle login is used automatically in the background
- No separate passwords or credentials needed
- Works for private communities, restricted posts, and member-exclusive lessons
- Downloads happen entirely on your device with no data sent to third parties
Frequently Asked Questions
Q: What sites does this extension support?
A: Circle.so (and Circle.com), Tella.tv, Loom.com, YouTube.com, Vimeo.com, and Wistia.com. It also detects generic embedded video players on approved embedded contexts.
Q: Does this work on native Circle videos?
A: Yes.
Q: Does this work on 2+ hour long videos?
A: Yes.
Q: Does this work on Loom/Tella videos embedded in Circle?
A: Yes.
Q: Can I download multiple videos at once?
A: Yes. The extension supports up to 3 concurrent downloads with individual progress tracking. Additional videos are added to an automatic queue.
Q: What quality options are available?
A: The extension detects all available resolutions from the source platform and lists them in the quality selector, sorted highest to lowest. Each option shows resolution, bitrate, and estimated file size.
Q: Does downloading preserve the original quality?
A: Yes. For adaptive streams (HLS/DASH), the extension downloads segments and merges them into a single MP4 without re-encoding. Direct MP4 uploads are saved at full quality instantly.
Q: Where are my downloads saved?
A: Videos automatically save to a Circle Downloader subfolder inside your browser's default Downloads directory. You can also set a custom default download location.
Q: Can I download member-only or private content?
A: Yes. If you can view the post in Circle, the extension can download it using your existing Circle login. Authentication happens automatically in the background.
Q: Why isn't the extension finding my video?
A: Press play on the video first. The extension needs the stream to start before detection works. If issues persist, refresh the page and try again.
Q: Is there a free trial?
A: Yes — 3 free downloads after email sign-in. No credit card required. Unlimited downloads available with a license.
Q: Is my data safe?
A: Yes. All video processing happens entirely in your browser. No video data is sent to external servers. Your Circle login credentials are never shared.

About
Circle.so is a community platform for creators, educators, and businesses to host courses, coaching programs, and member communities. However, like many course platforms, they don't provide a way to download the videos that you (the actual users) pay for access to — or even offer an offline viewing option.
So we created a way for you to download your Circle.so community videos even if you're not technically inclined.
