Perplexity: Build a Living Knowledge Base (2026)
🚀 Quick start
- Create a Perplexity account and upgrade to Pro if you need Collections and Pro Search.
- Open the sidebar, click Collections, and create a new Collection with a specific name.
- Inside the Collection, set Focus to Research and run your first cited query.
- Save 5–7 queries, then re-run them weekly to keep the knowledge base fresh.
💡 Why use Perplexity for this
Perplexity Collections let you group related queries into a persistent, cited research workspace. Instead of scattered bookmarks, you save threads that can be re-run to refresh results. This guide walks through creating a Collection, using Pro Search with the Research focus, and maintaining it weekly. Note: Collections and Pro Search require a paid Perplexity Pro subscription (pricing checked 2026-10-15).
🛠️ How to Build a Living Knowledge Base (6 steps)
Step 1
Open Perplexity in your browser. On the left sidebar, click the 'Collections' icon (folder-shaped). If the sidebar is collapsed, click the hamburger menu (three lines) at top-left to expand it.
Step 2
Click the '+ New Collection' button. Enter a specific, searchable name (e.g., 'Competitive Intel - Q2 2026'). Optionally add a description. Click 'Create'.
Step 3
Inside the new Collection, locate the search bar at the top. Click the 'Focus' dropdown and select 'Research' (this enables Pro Search mode for cited, comprehensive answers). Leave 'Sources' as 'All' for maximum coverage.
Step 4
Type your first research question into the search bar. For example: 'What new features have [Competitor Name] launched in the last 30 days? Include official announcements and analyst reactions.' Press Enter. Wait for the response, which will include citations.
Step 5
Repeat step 4 to add 5–7 total queries covering different aspects of your research focus. Each query becomes a saved thread in the Collection.
Step 6
To refresh, open the Collection and click 'Re-ask' on any saved query to re-run it with current web data.
📦 What you'll get
After completing these steps, you will have a Perplexity Collection containing 5–7 saved research threads, each with cited answers and source links. Re-running a query updates the answer with fresh citations.
