Yes. Grind brings the LeetCode routine to system design: pick a question, attempt it, get feedback, and revise. You talk through your decisions while Grind builds an editable diagram, then check each step before moving on.
The harder question is what you need to practise. Following a good architecture in a walkthrough is easier than explaining one from a blank canvas, and the interview asks for the second. Look for practice that makes you do it.

What the LeetCode comparison gets right
The part worth copying is the repeated attempt. You need a clear problem, a place to work, feedback that points to a gap, and another chance to fix it. LeetCode's official getting-started guide describes its coding problems, learning resources, and interview preparation.
For system design, keep the attempt-and-review habit and change what an attempt contains. Instead of submitting a function, you clarify requirements, define an API, draw a request path, and explain how the design behaves when a dependency fails. What you hand in is a diagram plus the reasoning that ties it to the requirements.
What changes when the answer is an architecture
Take a URL-shortener exercise where links are opened about 100 times as often as they are created. A cache can reduce database reads. Explain what it stores, what happens on a miss, and which store holds the authoritative copy.
Now add a requirement that owners can disable links immediately. You have to discuss stale cache entries and invalidation. Several designs can work, depending on the guarantees you choose. Feedback should assess those guarantees and trade-offs rather than demand one memorised arrangement of boxes.
So treat a model answer as one reference design. If you cannot say which assumption makes its cache policy reasonable, copying its diagram skips the part an interviewer will ask about.
Practise saying the part you usually skip
It is easy to read "use a queue" and fill in the rest in your head. Try explaining the same decision aloud: what is acknowledged, where work becomes durable, what a worker retries, and how a duplicate is handled.
If you cannot say when a queued job becomes durable or what happens after a duplicate delivery, work through those cases before moving on.
Use this check during practice. After each decision, say why it meets a requirement and what it gives up. "The queue absorbs bursts" needs a second sentence about the delay users might see. "The cache reduces reads" needs a second sentence about freshness.
How Grind's practice loop works
Choose a system-design question and start an attempt. Grind takes you through requirements, core entities, API design, high-level design, and deep dives, with a data-flow step on questions that need one.
You can answer by voice, typed commands, or direct editing. Lycana writes down what you say as points, or as changes to an editable diagram. Check a step when you are ready. The feedback says what your design covered and missed against the question's criteria, and you can revise before continuing. You can ask for a hint during any step. Finishing the attempt gives you overall feedback and opens the question's example design.
The guided format gives you time to work on a difficult decision. If your explanation skips how a failed write is retried, you can revise that part of the design and check it again before moving on.
Questions and articles are public to read. Starting an attempt requires an account. A Free account gets one free question, ever, chosen from the offered junior or mid-level questions. Further practice requires Lycana Pro; see current plan details.
Use learning resources alongside your attempts
If you need a structured learning path, Educative's Grokking Modern System Design Interview combines fundamentals, design case studies, quizzes, and AI mock interviews. It helps most when an unfamiliar concept is what stops your attempt.
Hello Interview offers guided system-design exercises and feedback. When choosing your daily practice, look at how you will explain a decision, change the diagram, and work through what you missed. In Grind, those actions happen within each step of your attempt.
Aced, formerly Exponent, offers reciprocal peer mock interviews that include system design. Its separate AI mock interviews advertise audio conversation and system-design questions. A peer gives you another person's questions; a guided exercise gives you feedback on one stage at a time.
DesignLoop and SystemDesign.so focus on interview simulations.
Use Grind to put what you study into practice. For each component you add, explain the request it handles, the guarantee it provides, and the failure you still need to account for. Check your design and revise the missing decisions while they are fresh.
Make the feedback useful before switching questions
For your first URL-shortener attempt, pick one thing to inspect: whether you can follow a redirect from the client to storage and back without skipping a component.
Say the path aloud before checking the step. If feedback shows a missing decision, explain the fix in your own words and update the diagram. An attempt teaches you more when you can point to the decision you changed.
If the gap is narrower, try the API rate-limiter question. Explain how two servers avoid spending the same final token, then decide what happens when the shared counter store is unavailable. Read the worked example after you have formed your own answer.
In the next session, close the walkthrough, start from the question, and speak the reasoning again. Check whether you can rebuild the decision and its trade-off without borrowing the article's wording.
