Complexity

An enhanced version of Perplexity.ai which everyone has ever wanted.
Community-driven, open-source, and free to use.

Complexity is a third-party extension, it does NOT affiliate with Perplexity.ai.

💖 support the development

Perplexity.ai is famously known for its LLM-based search engine, but many may not know that it is also a decent portal which provides access to various SOTA LLMs and image generation models and have somewhat a very generous rate limit compared to other services. But it lacks a lot of basic features, the UX isn't that great either. Hence, Complexity was created to fill that gap.

• Various UI/UX/QoL tweaks.
• LLM/Image gen model selectors; directly chat to a collection; export your searches/conversations, etc.
• Highly customizable ADHD-friendly theme (custom css is supported).
• A dedicated solution for prompts management: Prompts Library (in development).

This is a high-level overview of the network traffic interception approach, which provides the extension with the ability to alter the behavior of the host page.

• Chrome Web Store
• Mozilla Add-on
• Releases

1. Clone this repository
2. pnpm clean-zip
3. Load the extension from the zip file in the package folder.

The mozilla add-on version is available at the moz branch.

• Because of frequent/unexpected changes in the host page, UI tweaks are prone to breakage and it will take some time for the review process to be passed.
• The dev runtime/overall DX on mozilla-based browsers is non-existent due to a non-compatible dev dependency @crxjs/vite-plugin.
• Limited testing: the e2e test suite has not been implemented due to the agressive Cloudflare protection of the host page itself (I'm still figuring out a way 🙂)

• Issues and PRs are welcome.
• Please follow the guidelines in CONTRIBUTING.md.

• The Discord community for the constant feedbacks/suggestions and support.
• Perplexity.ai for an amazing product. (almost 😅)
• DailyFocus for the name "Complexity" and early feedbacks/testing.
• DanielLatorre for the #72AEFD default accent color.
