AssLoader is a free Chrome add-on developed by 龟丞相. It falls under the Browsers category and specifically the Add-ons & Tools subcategory. This add-on allows users to load local .ass subtitle files to online videos by simply clicking the icon in the toolbar and rendering the subtitle file. The add-on then attaches the subtitle to the

While AssLoader is not a well-designed product, it serves its purpose and can be useful for those in need. The developer published it to address the annoyance of Chrome's warning in development mode. However, there are several inconveniences that users should be aware of. Firstly, users need to click somewhere on the page before clicking the icon, otherwise, the select-file-dialog will not pop out as the browser stops it. Additionally, after loading the subtitle, users have to pause and restart the video to display the subtitle in the correct size. If users want to load a new .ass file, they have to refresh the page. AssLoader also does not handle time offsets, so users would need to modify the .ass file using other tools if they require this feature. Resizing the video element may also require users to pause, change the playback time, and restart the video multiple times to make the subtitle resize properly. It's worth noting that this extension may not work on all video websites as it has not been extensively tested.

AssLoader is an open-source project, and if this feature proves to be useful to many people, it is likely that someone else will take on the task of improving it further. For more information, visit the project's website.
