doubaoAssistant is a browser add-on for Doubao and Dola, the international version of the same chat assistant, that helps you pull out the images and videos those chatbots generate in a conversation without the watermark the platforms normally add. It also adds a switch to extend a video feature called Seedance from its normal 5 or 10 second limit up to 15 seconds, and it can save and switch between several different Doubao accounts on the same browser. Inside a chat, the tool opens a small workbench that lists the images and videos from that conversation, grouped by topic, using thumbnails so nothing large loads until you choose to download it. From there you can download one item at a time, copy its link, open it in a new tab, or select several items and either download them one by one or bundle them into a single ZIP file, all done inside the browser. The Seedance 15 second option works by turning on a toggle in the workbench, which adds a new 15 second choice to Doubao's own video length menu. Turning the toggle off removes the option and returns the app to its normal choices. There is also a button that fills in and sends a specific prompt tied to this 15 second feature. Account management only works on the main Doubao site, not Dola, and lets you save your current logged in account, add and switch between several accounts, rename them, or remove a saved one, all stored locally in the browser rather than on a server. It installs either as an unpacked Chrome or Edge extension in developer mode, or as a Tampermonkey userscript, though the userscript version skips the account switching feature. The Seedance enhancement idea builds on an earlier open source project. It is released under the MIT license, and the author notes it is meant for learning and personal productivity use.
