LeetCode Hint Engine

About

LeetCode Hint Engine is a Chrome extension that assists with Data Structures and Algorithms practice by simulating the hint-giving process of a real coding interview.

In a technical interview, when a candidate is stuck, the interviewer typically does not give away the solution, they guide the candidate toward the right approach with small, progressive nudges. This extension replicates that experience. When you are unable to make progress on a problem, you can request up to 3 hints, revealed one at a time:

Hint 1 — Guides you toward the general approach
Hint 2 — Identifies the relevant data structure and explains its suitability
Hint 3 — Provides partial pseudocode to help you move forward
The extension connects to an AI provider of your choice (Groq, Gemini, OpenAI, Claude, or Cohere) using your own API key.

GitHub Integration

The extension can be connected to a GitHub repository. When a submission is accepted on any supported platform, the solution is automatically saved to the configured repository as a Markdown file, organized by platform and problem name. This keeps all solved problems in one place regardless of which platform they were solved on.

Supported Platforms: LeetCode · GeeksForGeeks · TakeYouForward

Note: API keys and the GitHub access token are stored locally in the browser and are never sent to any server other than the chosen AI provider.
