Customizable AI new tab, live sidebar, reusable prompt manager, quick launch, and YouTube/page extract - one browser workspace. Synapse is a browser workspace.
It keeps the same working surface available in two places: a customizable New Tab and a live sidebar on normal web pages. That lets you keep launch tools, saved links, prompts, and page context close while you work instead of rebuilding the same setup across tabs.
