Note

The extension only activates on leetcode.com problem pages. It does not run on any other website and does not read your browser history, tabs, or other site data.

Tip

You can manage or revoke connected devices any time from Settings → Connected Devices in the web app.

The Extension Sidebar

When you open any LeetCode problem page, the AlgoTrace button appears in the bottom-right corner of the screen. Click it to slide open the sidebar.

The sidebar has five parts:

·Problem header — shows the problem name, difficulty badge, and your attempt status.
·Message history — scrollable conversation thread that persists for the session.
·Chat input — type your question; send with Enter.
·Mode selector — switch between Learning, Reasoning, and Image modes.
·Action bar — Hint button, complete button, and quick action chips after AI responses.

Chat Modes

Three modes are available from the pill selector at the bottom of the sidebar. Choose based on what you need right now.

Mode	Model	Best for	Plan
Learning	Trace AI (Standard)	Hints, concept questions, pattern recognition — fast responses	Free+
Reasoning	Trace AI (Advanced)	Complex analysis, time complexity proofs, multi-step reasoning	Pro / Max
Image	Trace AI (Vision)	Paste a screenshot of your code or a whiteboard	Pro / Max

Plan

Reasoning and Image modes require a Pro or Max plan. Free users can use Learning mode with full functionality.

Hints & Smart Actions

The Hint Button

Clicking Hint sends a contextual nudge request — the AI gives you a push in the right direction without revealing the full solution. Good for when you're stuck but want to figure it out yourself.

Click Hint → nudge response

Smart Actions

After every AI response, a row of quick-action chips appears below the message. These change based on what was discussed. Common actions:

·Save to Notebook — creates a note from this exchange in your current notebook.
·Explain this approach — asks the AI to elaborate on the last suggestion.
·Show edge cases — asks for edge cases relevant to the discussed algorithm.

Code-Aware Responses

The AI can read your current code from the LeetCode editor when you ask questions like "what's wrong with my approach?" or "why is this failing?" It will reference specific lines and variable names from your submission.
