Space Tabs: Arc-like Spaces & BYOK AI

Move your Arc workspace into Chrome. Organize Spaces, ask pages with your own AI key, and keep workspace data local.

Space Tabs is a Chrome side panel for organizing browser work into Spaces, folders, Chrome tab groups, and dormant saved tabs. Use it to keep separate work contexts without keeping every saved tab loaded. Create Spaces for projects, clients, classes, trips, or research threads. Store tabs locally, reopen them when needed, and keep temporary tabs separate from saved work. Features: - Spaces for separate browser work contexts. - Folders with nested saved tab organization. - Chrome tab group integration. - Dormant saved tabs that stay unloaded until opened. - Panel-only tab names for cleaner workspace labels. - Drag sorting for groups and tabs. - Multi-select grouping with Cmd/Ctrl and Shift. - Duplicate, close, discard, rename, and move tab actions. - Arc StorableSidebar.json import. - User-editable keyboard shortcuts. - Optional BYOK AI for Ask Page, page summaries, and tab grouping. AI features are optional. Space Tabs works without an AI API key. When AI is configured, requests are sent to the AI endpoint selected by the user.
