Complexity

Complexity is an open-source project designed to make your time on Perplexity.ai smoother and more enjoyable. Instead of settling for the platform's default setup, it layers in a collection of practical features and refinements that adapt the experience to the way you actually work and browse.

With Complexity, you can switch between your preferred AI models right inside a thread, and even use Claude.ai's Artifacts within Perplexity. Navigating and chatting with your Spaces becomes effortless, so organizing your research and conversations feels natural rather than cumbersome.

Sharing and preserving your work is simple too—export any thread as markdown with just a few clicks. On top of that, Complexity lets you customize themes and fonts to match your personal style, offers multilingual support, and ships with numerous quality-of-life improvements that iron out the small daily frictions.
