## What it is
Complexity is a browser extension suite that enhances AI chat web apps, currently targeting Perplexity AI on Chrome, Firefox, Firefox Android, and the Comet browser. It adds quality-of-life features such as on-the-fly model and focus mode switching, thread table of contents, sticky toolbars, custom themes, markdown export, and syntax-highlighted code blocks.

## Use cases
- enhance perplexity ai with more features
- change ai model mid-conversation in perplexity
- export perplexity threads to markdown
- customize the look of perplexity with themes and fonts
- add a table of contents to long ai chat threads
- use perplexity extensions on firefox android
- improve code block syntax highlighting in ai chats

## When to choose
- you are a daily Perplexity AI power user wanting UI/UX and workflow improvements
- you want to switch models or focus modes without leaving a thread
- you need thread export, custom themes, or better code rendering in Perplexity

## When to avoid
- you use a different AI chat app not yet supported by the suite
- you need an official, unmodified Perplexity experience or are concerned about unofficial extension changes breaking
- you need a standalone app rather than a browser extension
