You have a Perplexity thread with useful answers, but it sits outside any Space. You want to organize it inside a Space so that the thread inherits the Space’s instructions, sources, and sharing settings. Moving a thread into a Space is a simple drag-and-drop operation that takes less than a second. This article shows the exact steps to move any existing thread into a target Space and explains what happens to the thread after the move.
Key Takeaways: Move a Thread Into a Perplexity Space
- Thread list > drag thread onto Space name: Moves the thread instantly with no confirmation dialog.
- Space sidebar > expand to see all Spaces: You must see the target Space name before dragging.
- After move, thread uses Space instructions: Future answers in that thread follow the Space’s custom prompt and sources.
What Happens When You Move a Thread Into a Space
A Perplexity Space is a container that groups threads, custom instructions, and shared sources. When you move a thread into a Space, the thread is relinked from your personal “threads” area to that Space. The thread’s existing messages and answers remain unchanged. However, any new questions you ask inside that thread will use the Space’s custom instructions, model selection, and attached sources instead of your default Perplexity settings.
The thread does not duplicate. It moves from one location to another. If you move the thread back out of the Space, it returns to your personal thread list and loses the Space-specific settings. The Space’s sharing settings apply to the thread after the move. If the Space is shared with a team, all members see the moved thread and can continue the conversation.
Prerequisites
You need a Perplexity account with at least one Space already created. You can create a Space from the left sidebar by clicking the plus icon next to Spaces. The thread you want to move must be in your thread history. You can find it on the left sidebar under the History section or by using the search bar at the top of the thread list.
Steps to Move a Thread Into a Perplexity Space
The operation uses drag and drop. You cannot move a thread using a menu or keyboard shortcut. Follow these steps exactly.
- Open the thread list
Click the History icon on the left sidebar. The icon looks like a clock. A list of your recent threads appears. If you have many threads, use the search box at the top of the list to find the specific thread you want to move. - Expand the Spaces section in the sidebar
On the left sidebar, scroll down until you see the Spaces section. If the section is collapsed, click the small triangle or chevron icon next to the word Spaces. The list of your Spaces expands. You must see the name of the target Space before you start dragging. - Drag the thread onto the Space name
Click and hold the thread name in the History list. Drag it horizontally to the left sidebar. Position the cursor directly over the target Space name. A blue highlight appears around the Space name when you hover over it. Release the mouse button to drop the thread into the Space. - Verify the thread moved
Click the Space name in the left sidebar. The thread list for that Space opens. You should see the moved thread at the top of the list. Click the thread to open it. The thread’s messages are intact. The Space name appears at the top of the thread window.
If a Thread Does Not Move Correctly
The Space Name Does Not Highlight When I Drag
The Space list may be collapsed. Click the triangle next to Spaces to expand the section. If the list is expanded but still no highlight, refresh the page by pressing Ctrl+R. After the refresh, try the drag again. If the problem persists, log out and log back into your Perplexity account.
The Thread Disappears After the Move
The thread moved successfully but you are looking in the wrong Space. Open each Space in your sidebar and check the thread list. The thread is inside exactly one Space. If you cannot find it, use the global search bar at the top of the page and type part of the thread title. The search results show the Space name next to the thread.
The Thread Contains Old Answers That Do Not Match the Space Instructions
This is expected behavior. Only new questions use the Space instructions. Existing answers remain unchanged. If you want to regenerate an old answer, scroll to that answer and click the Regenerate button at the bottom of the message. The new answer will use the Space’s custom prompt and sources.
Perplexity Thread Location: Personal vs Space
| Item | Personal Threads | Threads Inside a Space |
|---|---|---|
| Default location | History section in left sidebar | Inside the Space’s thread list |
| Uses Space instructions | No | Yes, for new questions |
| Visible to Space members | No | Yes, if Space is shared |
| Can be moved again | Yes, drag to another Space | Yes, drag out or to another Space |
| Duplicate on move | No | No, thread is relocated |
You can now move any existing thread into a Perplexity Space using the drag-and-drop method. After the move, test the thread by asking a new question and confirm that the answer follows the Space’s custom instructions. For advanced organization, consider creating multiple Spaces for different projects and moving relevant threads into each one. You can also drag a thread from one Space into another Space to reorganize your work without losing any conversation history.
