Alt Peek

Preview links and quickly search or copy selected text without leaving the current page.

Alt Peek lets you inspect a supported link in a focused overlay before deciding whether to open it in a tab. Use Alt + Click, Option + Click on macOS, or an optional long press to open a preview while keeping your current page in place. The extension also offers contextual actions that support the same workflow: copying a link, opening a preview in a nearby tab, searching or copying selected text, choosing how the preview looks, and disabling previews on individual sites. If enabled in settings, an optional Paste button can appear after you click a supported text field when the clipboard contains text. Paste can keep formatting in supported editors or insert plain text. Clipboard content is handled locally; it is never stored or sent by Alt Peek. Alt Peek does not replace the new-tab page, home page, startup page, or default search provider. It does not include ads, analytics, telemetry, behavioral tracking, or remotely hosted code.
