Collab Sessions, AI debug hints, and rebuilt Learn ladders
- changelog
The first big batch of updates is live. Here's what you'll notice.
Collab Sessions
You can now solve a problem together. Start a Collab Session, invite up to two friends with a code, and you all edit the same code in real time. Great for pair practice, mock interviews, or walking someone through a solution.
"Why isn't my code working?"
When a submission fails, you can now ask the AI for a debug hint straight from the verdict header. It looks at your code and the failure and nudges you toward the bug without handing you the answer.
Rebuilt Learn ladders
Nearly every Learn category got a rebuilt ladder with a clearer progression: Hash Maps, Two Pointers, Binary Search, Prefix Sums, Stacks & Queues, Sliding Window, Merge Intervals, Line Sweep, DFS, BFS, Backtracking, Kadane's, Greedy, Monotonic Stack, Topological Sort, Union-Find, Shortest Paths, and a brand-new 17-rung Dynamic Programming ladder organized into 8 sections.
Smaller improvements
- Connect your accounts. Link Google, GitHub, and Twitch to your profile from Settings, so you can sign in with any of them.
- Collapsible side panel. The Chat/Activity panel in the workspace now collapses out of the way when you want the full width for code.
