Space Live Caption Viewer is a Chrome extension developed by akinori.oyama. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This free extension provides users with the ability to view the majority of the live captions in Twitter Spaces.

With Version, Space Live Caption Viewer displays all the captions that include previously captioned lines. This preliminary measure allows users to expand the visible area by showing the captions in a separate area.

In Version, the extension takes it a step further by automatically starting the Twitter Space and capturing the captions when a space is available. This feature is activated when the outer circle of a Twitter profile indicates the availability of a space. Users can configure this option under "Auto start space..."

Space Live Caption Viewer is a useful tool for those who want to enhance their experience in Twitter Spaces by having access to captions in a convenient and easily accessible manner.
