How to Bulk-Delete Multiple Threads From the Library

Your Perplexity Library can quickly fill with dozens or hundreds of threads from daily searches, research sessions, and saved answers. Manually deleting each thread one by one is slow and frustrating. Perplexity does not include a native Select All or batch delete button in the Library view. This article shows three reliable methods to bulk-delete multiple threads from the Library using the web interface and keyboard shortcuts.

Why Perplexity Library Lacks a Built-in Bulk Delete Button

The Perplexity Library is designed as a chronological feed of your past searches and threads. Each thread appears as a card or list item with a title, date, and a three-dot menu for individual actions. The interface prioritizes quick access to recent threads over batch management tools.

Perplexity does not expose a Select All checkbox or a Delete Multiple button in the Library view. This is a deliberate design choice to keep the interface clean and prevent accidental mass deletions. However, the web interface respects standard browser keyboard and mouse interactions. You can use Shift-click and Ctrl-click to select multiple threads and then delete them together.

The method works on Windows 11, Windows 10, macOS, and Linux browsers. It does not require any third-party extensions or scripts. The selected threads are permanently removed after you confirm the deletion.

Steps to Bulk-Delete Threads Using Shift-Click and Ctrl-Click

You can delete multiple threads from the Library in a single action using standard browser selection techniques. Follow these steps carefully.

1. Open the Perplexity Library
   Go to perplexity.ai and sign in to your account. Click Library in the left sidebar. The Library displays all your saved threads in reverse chronological order.
2. Select a range of adjacent threads
   Click the first thread you want to delete. Hold the Shift key on your keyboard. Click the last thread in the range you want to delete. Perplexity highlights all threads between the first and last click.
3. Select non-adjacent threads (optional)
   If you need to delete threads that are not next to each other, hold the Ctrl key on Windows or the Command key on Mac. Click each thread you want to delete. Each clicked thread becomes highlighted while others remain unselected.
4. Press the Delete key
   With the desired threads highlighted, press the Delete key on your keyboard. A confirmation dialog appears: Are you sure you want to delete these threads? This action cannot be undone.
5. Confirm the deletion
   Click Delete in the dialog. Perplexity removes all selected threads from your Library immediately. The threads are gone permanently and cannot be recovered.

Steps to Bulk-Delete Threads Using the Three-Dot Menu

If you prefer using the mouse over keyboard shortcuts, you can delete threads one by one from the three-dot menu. This method is slower but works on touch devices or when you have only a few threads to remove.

1. Open the Library
   Navigate to perplexity.ai and click Library in the left sidebar.
2. Click the three-dot menu on a thread
   Hover over any thread card. Click the three-dot icon that appears on the right side of the thread. A dropdown menu opens.
3. Select Delete
   Click Delete in the dropdown. A confirmation dialog appears.
4. Confirm the deletion
   Click Delete in the dialog. The thread is removed from your Library.
5. Repeat for each thread
   Repeat steps 2 through 4 for every thread you want to delete. This method does not support batch selection.

Steps to Bulk-Delete Threads Using the Search Filter

If you want to delete threads from a specific date range or search query, you can use the Library search bar to narrow down the list before selecting and deleting.

1. Open the Library and search
   Go to perplexity.ai and click Library. In the search bar at the top of the Library, type a keyword or date range. For example, type weather to show only threads containing that word.
2. Select all visible threads
   After the search results appear, use Shift-click or Ctrl-click to select the filtered threads as described in the previous section.
3. Press the Delete key
   Press Delete on your keyboard. Confirm the deletion in the dialog.
4. Clear the search to see remaining threads
   Click the X in the search bar to clear the filter. Repeat the process for other keywords or date ranges if needed.

Common Issues When Bulk-Deleting Threads

Shift-click Does Not Select Multiple Threads

This happens when you click the thread title or body instead of the thread card border. Click directly on the thread card area, not on the title text or the date. The card background should highlight when selected.

Delete Key Does Nothing

Some browser extensions block the Delete key for safety. Try disabling extensions like Grammarly or LastPass temporarily. Also ensure you are not typing in a text field — click an empty area of the Library first.

Selected Threads Are Not Highlighted

The selection highlight may be very faint on some themes. Look for a subtle blue or gray border around the thread card. If you see no change, release the Shift or Ctrl key and try again. Click an empty area to reset the selection.

Confirmation Dialog Does Not Appear

Perplexity shows the confirmation dialog only when at least one thread is selected. If you press Delete without a selection, nothing happens. Verify that at least one thread card shows a highlighted border.

Perplexity Library Bulk Delete: Web vs Mobile

Item	Web Browser (Desktop)	Mobile Browser or App
Selection method	Shift-click or Ctrl-click	Tap and hold, then tap additional threads
Delete trigger	Delete key or three-dot menu	Three-dot menu only
Batch delete support	Yes, with keyboard shortcuts	No native batch delete
Undo after deletion	No undo available	No undo available

The web browser method using Shift-click and the Delete key is the only way to bulk-delete multiple threads in Perplexity. Mobile users must delete threads individually from the three-dot menu.

You can now quickly clean up your Perplexity Library by selecting multiple threads with Shift-click or Ctrl-click and pressing Delete. Use the search filter to narrow down threads by keyword before selecting them. This saves time compared to deleting each thread one by one from the three-dot menu. For future organization, consider using Collections to group related threads instead of keeping everything in the main Library.
