Background

Organizing many open tabs manually is slow. Users need a safe way to group eligible tabs with their configured AI model while keeping existing groups and tabs intact.

Changes

  • Add AI actions to classify eligible tabs in the current window or below a selected tab.
  • Reuse existing folders as categories and create new ones only when needed.
  • Add Settings controls to add, rename, and delete tab categories without closing their tabs.
  • Protect classification from stale results, tab changes, invalid model output, oversized requests, and concurrent folder edits.
  • Add localized feedback, documentation, changelog entries, and cross-window folder refreshes.

Testing

  • Added C++ unit tests for agent configuration and folder storage edits.
  • Added sidebar, Agent WebUI, Settings WebUI, and folder-settings Vitest coverage.

Summary by CodeRabbit

  • New Features
    • Added AI-assisted classification for eligible, ungrouped tabs using your configured model. You can classify loose tabs in a window or tabs below a selected tab; existing groups are preserved and reused where possible.
    • Added Settings controls to add, rename, and remove tab categories. Removing a category releases its tabs without closing them.
  • Bug Fixes
    • Classification results for tabs that remain open are retained when other tabs close during processing. Results are also saved when older folder data contains duplicate tab references.

Adds folder add, rename, and remove operations with name validation, plus asynchronous WebUI reads and edits. Classification writes compare normalized folder snapshots before updating the file.
Model classification request and validation

Adds provider-key configuration checks and a request flow that validates tab metadata and model output. Requests support cancellation and timeouts, reject tool calls, and enforce entry and size limits.
Sidebar selection, application, and saving

Adds whole-sidebar and below-tab classification commands. The sidebar selects eligible loose tabs, applies valid groups, and saves results against the captured folder snapshot. It handles stale results and tab closures and reports classification status. Documentation describes the feature and checklist expectations.
Category settings interface and integration

Adds category add, rename, and remove controls in Settings, including load, validation, and edit-error states. Registers the category browser handler and adds Settings tests. The Settings UI patch also sets signinAllowed to false unconditionally.

Merge Risk: 🔵 Low · up to 6dcda

On pinned tabs, "Classify Tabs Below with AI" appears in the menu but always reports that there is nothing to classify. Hiding the option for pinned tabs is a small fix. Otherwise, the feature looks ready to merge.

Hide "Classify Tabs Below" for pinned tabs.

HandleShowTabContextMenu handles pinned tabs too, as the existing IsTabPinned checks show. A pinned tab is in pinnedTabs_, not unpinnedTabs_. In getClassificationTabs, the anchor match therefore never sets below. The result is an empty list, so the menu item always shows "No tabs to classify". docs/features.md also says this action applies only to ordinary tabs.

Add the item only when the tab is not pinned. Apply the same rule in IsCommandIdEnabled at Lines 3994-3995.

Proposed fix
-    if (context_menu_tab_index_ >= 0) {
+    if (context_menu_tab_index_ >= 0 && !model->IsTabPinned(tab_index)) {
       tab_context_menu_model_->AddItem(
           kClassifyTabsBelow,
           l10n_util::GetStringUTF16(IDS_DAO_CLASSIFY_TABS_BELOW));
     }
// IsCommandIdEnabled
const int below_index =
    ResolveDraggedTabIndex(browser_, -1, context_menu_tab_id_);
return ... && (command_id == kClassifyTabs ||
               (below_index >= 0 &&
                !browser_->tab_strip_model()->IsTabPinned(below_index)));
