About Comment-On
A single home for the conversation around content hosted elsewhere, even when the original platform turned comments off.
How it works
- Paste a link to a video, post or channel. We work out what it points to.
- Land on its one discussion. Every way of linking to the same thing (share links, mobile links, reposts) leads to the same conversation.
- Join in. Threaded comments, votes and replies, no matter what the original platform allows.
Supported platforms
YouTube, TikTok, Instagram, and Spotify, with more planned. Paste an unsupported link anyway; misses are logged and help decide what to add next.
Privacy first
