This extension feels like having a fact-checker sitting next to me while I scroll through social media. Subtle, helpful, and not annoying.

Overleaf Copilot·19 Jan 2026

The killer feature is the passive auto protection that runs in the background. Like a guardian angel protecting me from misinformation.
