How to Save Prompts in Perplexity

When you are signed in, a conversation is stored on the History page and normally stays there until you delete it. Perplexity now calls a conversation a session; it used to be a thread. History has a search by keyword or title, and Ctrl+K on Windows or Cmd+K on a Mac opens that search from wherever you are.

Some sessions do not last. Perplexity says a session can be temporary and expire when you attach a file or use a connector. Signed out, a session disappears after 14 days, and an incognito one after 24 hours. And what you find again is the conversation, with the prompt somewhere inside it.

• Custom instructions, in the personalization settings, are a free-text field for your preferences, interests and style. They are about you, for every query.
• Projects, which were called Spaces until July 2026, hold conversations, files and their own instructions of up to 8,000 characters. Good for one subject you keep coming back to.
• Skills belong to Computer, Perplexity’s agent mode: each one gives Computer a method for a kind of task, and it starts when a request matches.
• Shortcuts, saved prompts called with a slash, are a feature of Comet, Perplexity’s browser. In the web app’s settings, the Shortcuts page now says they have moved to Skills.

For an ordinary search in the web app, Perplexity’s help centre describes no place to keep a prompt and call it back.

1. Install PromptTray from the Chrome Web Store and open Perplexity. You do not need an account: prompts are saved in your browser, and signing in later adds sync and a backup.
2. Type or paste the prompt in the message box. A Save button appears in the box as soon as there is text.
3. Press Save. PromptTray’s panel opens with the prompt filled in and a title taken from its first line. Shorten the title, pick a category, add tags if you want them, and press Save Prompt.

To use it again, press CtrlShiftKControl Shift K in any chat. Spotlight opens over the page: type a few letters of the title and press Enter. The prompt is in the message box, and nothing is sent until you send it.

Research prompts repeat more than most: the question changes and the way you want it answered does not.

• Compare with sources: “Compare {option A} and {option B} on {criteria}. Give a source for each claim, and say where the sources disagree.”
• What changed recently: “What has changed about {topic} in the last {period}? List the changes by date, each with its source.”
• Find the original source: “Find the original source for this claim: {claim}. Say who published it first and whether later reports changed it.”
• Brief me before a call: “I am meeting {company} about {subject}. Summarize what they do, their last three announcements, and two questions worth asking.”

The words in curly braces are variables: PromptTray asks for them in a short form each time you insert the prompt. The guide to organizing AI prompts has the rules for titles, categories and tags.

The same library opens in 21 other apps, with the same shortcut. There is a guide like this one for ChatGPT, Claude, Gemini and Grok, and one on keeping one library across AI apps.
