Perplexity AI freezes after submission? Learn the causes and easy-to-follow fixes to stop the tool from getting stuck after prompt entry.
What Is the Perplexity AI Freezes After Submission Issue?
Sometimes, after typing a prompt and clicking submit, Perplexity AI simply stops responding. The screen doesn’t move, the loading icon spins endlessly, or worse—everything goes completely still. You might expect a fast, informative reply, but instead, you’re left waiting with no feedback or results.
This issue can happen across different browsers or devices and is often linked to temporary browser glitches, system-level conflicts, overloaded memory, or blocked network requests. Sometimes, it may be Perplexity’s server lagging behind, but in most cases, the freeze stems from something on the user’s side.
Fortunately, there are practical and effective ways to fix this issue, no matter your technical level.
Here’s why solving this matters:
- 🕒 Wastes Time During Important Tasks
A freeze means you have to rewrite, rephrase, or refresh—costing you time and focus. - 🚧 Disrupts Content Creation or Research Flow
Getting stuck mid-task can interrupt momentum, especially when writing or analyzing information. - 🧩 Can Point to Browser or Network Conflicts
Even a small browser issue or outdated extension can cause major freezing problems. - 🔄 Makes the Tool Seem Unreliable
Repeated freezes may lead users to abandon the platform entirely, even though fixes are available. - 🔐 Might Involve Session or Cookie Conflicts
Expired session tokens or corrupted cookies often freeze the interface unexpectedly.
Let’s walk through why this happens—and more importantly—how to get it working again smoothly.

🛠️ How to Fix Perplexity AI Freezes After Submission
If Perplexity AI freezes after you submit a prompt, there are clear actions you can take to bring it back to full speed. Most of these steps are quick and user-friendly—even if you’re not very technical.
Start with the basics and work your way through.
1. 🔄 Refresh the Page
🧠 Why it works:
Reloading resets scripts that might be stuck or unresponsive due to minor glitches.
📌 How to do it:
• Press Ctrl + R (Windows) or Command + R (Mac)
• Or click the refresh icon in your browser
• Re-enter your prompt after reloading
2. 🔧 Clear Browser Cache and Cookies
🧠 Why it works:
Corrupted cache or cookie data can cause interface freezing after input.
📌 How to do it:
• Go to browser settings → Privacy & Security
• Select “Clear browsing data”
• Check “Cookies” and “Cached images/files”
• Restart browser and test again
3. 🧪 Disable Browser Extensions
🧠 Why it works:
Extensions like ad blockers or privacy tools often block JavaScript functionality.
📌 How to do it:
• Launch your browser in incognito mode
• Visit Perplexity and test a prompt
• If it works, disable extensions one at a time in regular mode
4. 🌐 Check Internet Stability
🧠 Why it works:
Even momentary network drops can interrupt prompt submission and cause freezing.
📌 How to do it:
• Run an online speed test
• Switch to a stronger Wi-Fi or use wired internet
• Restart your router if needed
5. 🔁 Restart Your Device
🧠 Why it works:
A full restart clears background processes that might overload memory or GPU.
📌 How to do it:
• Save open work
• Fully restart your computer or device
• Open browser and try again
6. 🛡️ Adjust Antivirus or Firewall Settings
🧠 Why it works:
Overprotective software may freeze certain scripts triggered during submission.
📌 How to do it:
• Open your antivirus/firewall dashboard
• Add Perplexity.ai to your allowlist
• Temporarily disable the tool (just to test)
7. 🔄 Log Out and Back In
🧠 Why it works:
An expired login session may cause the interface to hang when submitting prompts.
📌 How to do it:
• Click on your profile icon
• Choose “Log Out”
• Wait 10 seconds, then log back in and test
8. 🌍 Switch Browsers
🧠 Why it works:
Some browsers may have updates or compatibility issues that cause prompt lag.
📌 How to do it:
• Use Chrome, Firefox, or Edge for testing
• Visit Perplexity in the new browser
• Submit your prompt and observe
9. 📏 Shorten or Simplify Prompt
🧠 Why it works:
Very long prompts can overload processing or lead to client-side timeouts.
📌 How to do it:
• Break your prompt into smaller chunks
• Submit more focused or single-topic queries
• Avoid sending long text blocks all at once
10. ⏳ Wait and Retry Later
🧠 Why it works:
Temporary backend load or updates may cause short freezing windows.
📌 How to do it:
• Wait 10–15 minutes
• Try the same prompt again
• Check Perplexity’s status page if needed
🧪 Advanced Troubleshooting Tips
If the freezing continues, here are advanced techniques for diagnosing and solving deeper system or network issues:
1. 🧬 Use DevTools to Inspect Script Errors
🧠 Why it works:
Detecting JavaScript failures or blocked requests can reveal the freeze source.
📌 How to do it:
• Right-click → “Inspect” → go to “Console” tab
• Submit a prompt and watch for error logs
• Look for red error messages like CORS or script blocks
2. 🌐 Change Your DNS Configuration
🧠 Why it works:
Some DNS providers may block or delay request resolution for AI services.
📌 How to do it:
• Open network settings
• Change DNS to Google (8.8.8.8 / 8.8.4.4) or Cloudflare (1.1.1.1)
• Save and restart your device
3. ⏱️ Sync System Time Accurately
🧠 Why it works:
Mismatched time settings can break session-based security layers in AI tools.
📌 How to do it:
• Open Date & Time settings
• Enable “Set time automatically”
• Restart browser and test again
4. 🔒 Inspect Security Headers with DevTools
🧠 Why it works:
Blocked or restricted security headers may prevent page interaction post-submission.
📌 How to do it:
• Open DevTools → Network tab
• Submit a prompt
• Check “Headers” of failing requests for CSP or X-Frame errors
