Perplexpin

PerplexPin keeps your preferred AI model locked in on Perplexity.ai and Comet browser — no more surprise resets.

Perplexity.ai tends to silently switch your selected AI model (Claude, GPT, Grok, etc.) back to a default after page reloads or navigations. PerplexPin fixes this by injecting a lightweight guard that persists your model choice across page loads, including in the Sidecar sidebar assistant.

How to use:
1. Click the PerplexPin extension icon → Copy Script
2. Open Perplexity.ai → press F12 → Console tab
3. Paste & run — pick your model from the popup
4. Done — your choice sticks across page loads

Features:
- Pin any AI model (Claude, GPT, Grok, and more)
- Optional Thinking mode toggle
- Works in both main search and Sidecar sidebar
- Persists across page reloads and navigations
- Self-healing: automatically re-injects if overwritten
- Zero runtime extension APIs — fully unblockable

To switch models later, just paste the script again.
