Of course! This is its basic functionality, but it's still in the alpha stage. If any problems are found, I can fix them quickly.

Hi HN, I’m rock, the creator of this extension. I frequently use Claude and ChatGPT for coding and research, but always found it painful to clean, save, or share these chats with colleagues without cluttering. So I built this to render clean documents.

Unlike online PDF converters, it does not send your chats to any backend server. Everything is rendered 100% locally in your browser to preserve privacy.

It’s built with Vanilla JS. One challenge was handling the custom markdown formats of different AI platforms (e.g., math blocks in ChatGPT, nested code structures in Claude). I had to write custom parsers for each AI platforms.

Let me know what you think.

I built an AI-powered Chrome extension that integrates directly with LeetCode to make interview preparation more efficient.

*Background:* Like many of you, I've been through the LeetCode grind multiple times. After getting frustrated with the inefficiency of traditional practice methods, I decided to build something better.

*What it does:* - *AI solution generation*: Get step-by-step explanations with complexity analysis for any problem - *Code debugging & optimization*: Upload your solution, get feedback and improvements - *Progress analytics*: Track performance, identify weak areas, monitor improvement - *Cross-device sync*: Practice data synchronized across devices - *Immersive mode*: Distraction-free coding environment

*Current status:* Very early beta (month 1 of testing). Works globally except China (North America has best performance). *Requires free subscription and LeetCode login.* Expect bugs and performance issues.

*Why I'm posting:* Looking for 50 committed beta testers who are: - Located anywhere except China (North America preferred) - Have active LeetCode accounts for solution submission - Active LeetCode users preparing for interviews - Comfortable with beta software and willing to provide feedback

*Beta tester benefits:* - Free subscription with special testing privileges - 200 problem-solving credits until Sept 1 (UTC), then 10/month - Direct communication with developer (me) - Lifetime discount on paid features - Input on product direction

*Setup requirements:* 1. Subscribe FREE at https://immersive-practice.vercel.app/ 2. Login to LeetCode for solution submission 3. Install extension (instructions provided after subscription)

*Key learning so far:* The biggest challenge isn't the AI accuracy (GPT-4 is remarkably good at LeetCode problems), but rather the UX of integrating AI assistance without disrupting the natural coding flow.
