Smart Tab Manager

About

Smart Tab Manager organizes a browser full of tabs into            
  intent-based categories and emergent workspaces. It works fully    
  offline; signing in with Google adds optional cross-device session 
  sync.                                                              
                                                            
  The problem

  Most tab managers either dump everything into a flat list or force 
  you into rigid workspaces you have to maintain by hand. Smart Tab
  Manager reads what you already have open and groups it on the fly  
  using URL, title, and native-group signals — so structure emerges
  from your actual browsing.

  How it groups tabs

  Two layers, applied automatically every time you open the popup:

  1. Thirteen intent categories — every tab is matched against       
  patterns for AI tools, Coding, Hacking, Work, Writing, Shopping,
  Social, News, Research, Learning, Travel, Wellness, and            
  Entertainment. Anything unmatched falls into "Other."     

  2. Dynamic keyword workspaces — any unigram or bigram appearing in 
  the titles of two or more tabs becomes an ad-hoc workspace. Three
  tabs about "Ad Blocker" → an "Ad Blocker" workspace. Tokens are    
  extracted from titles, camelCase identifiers, URL path segments,
  and native Chrome tab-group titles, so tabs cluster by what they're
   about, not just by hostname.

  Sessions

  • Save your current tab set under a custom name. Restore at any
  time.
  • Local-first — every save writes to chrome.storage.local first, so
   save and restore work offline, signed in or out.                  
  • Optional cross-device sync — sign in with Google and your saves
  are mirrored to a small backend so you can restore from any device.
  • Save just one group — every category card and workspace card has
  a pill button that saves only that group as a named session.       
   
  Operations                                                         
                                                            
  • One-click jump: clicking any tab row switches to that tab and
  focuses its window.
  • One-click close: hover a row to reveal an × that closes a single
  tab without dismissing the popup.                                  
  • Close groups: close every tab in a category or workspace with a
  single button.                                                     
  • Window switcher: a pill row at the top shows every open Chrome
  window with its tab count and active page.                         
  • Rename workspaces: double-click a title to rename it. Renames
  persist across reloads and across re-runs of the keyword clusterer.
                                                            
  Focus Mode                                                         
                                                            
  Closes every tab that isn't classified as Work, with a 5-second    
  cancel countdown so a misclick can't nuke your browser. The popup
  also nudges you with a Focus Mode suggestion when you cross 20 open
   tabs.                                                    

  Keyboard shortcuts

  Ctrl+Shift+Y (Windows/Linux) or Cmd+Shift+Y (macOS) opens the popup
   from anywhere. Inside the popup: ↓/↑ or j/k to navigate, Enter to
  switch, Delete or Backspace to close, s to save, r to restore, f   
  for Focus Mode, Esc to close.                             

  Privacy & data

  Sign-in is optional. The extension uses chrome.identity with the   
  minimum scopes (openid, email, profile) — only enough to identify
  which user a saved session belongs to. Tab URLs and titles never   
  leave your browser unless you explicitly save a session while
  signed in. The extension does not collect browsing history,
  ad-targeting data, or anything beyond what's needed for the
  features above.
