Frequently Asked Questions
Got questions? We've got answers. Here are the most common questions about LeetCopilot.
LeetCopilot is a Chrome extension that lives beside the problem on LeetCode. It understands your code, inputs, and error output to give in‑context guidance with step‑by‑step hints — no full spoilers by default.
Yes — free forever. We believe quality education should be accessible to everyone, so there are no hidden fees, subscriptions, or premium tiers.
No account is required. Install the Chrome extension and start learning immediately. Your progress and notes are stored locally in your browser.
LeetCopilot is available as a Chrome extension and works on Chromium-based browsers including Brave and Microsoft Edge. Support for Firefox and other browsers is on the roadmap.
Hints are designed to guide your reasoning without giving away the full solution. Because the copilot understands your current code and run output, it provides situationally relevant suggestions.
We don’t recommend using it during real interviews. Instead, use Interview Mode to practice explaining your solutions out loud and build confidence ahead of time.
