Last Round AI is completely free. That gets your attention immediately, especially if you’re in a job search and already spending money on resume tools, LinkedIn Premium, and maybe a Leetcode subscription. Free sounds like the obvious choice until you look at what you’re actually getting and whether it’s enough for the interviews you’re trying to pass.
I’ve used both. Here’s the honest breakdown.
What Last Round AI offers
Last Round AI provides real-time answer suggestions during live interviews, basic coding assistance, and invisible screen sharing functionality. It runs on Windows, Mac, and Web. The price is $0. For someone doing entry-level interviews or just starting to explore AI-assisted interview prep, it’s a reasonable place to start.
The honest limitation: there isn’t much public information about what models Last Round AI is running, how they handle response latency under load, or what their engineering resources look like. That’s not a criticism of the product. It’s just a real information gap. When you’re preparing for a final round at a company where the role matters, “I don’t know much about the underlying infrastructure” is relevant context.
Some free tools are free because they’re early-stage and building toward monetization. Some are free because they’re thinly built and that’s all they can support. I genuinely don’t know which category Last Round AI falls into, and I’d want to know before relying on it in a high-stakes interview.
What Craqly offers
Craqly is not free, but it has a free tier. 15 minutes of real usage, not a watered-down demo. The paid plans cover full interview sessions with real-time AI suggestions under 3 seconds, coding support for 20+ programming languages, mock interviews with feedback, resume building, mobile copilot functionality, and access to the Sales Assistant and Meeting Copilot if you use those at work.
Eight products under one account. That matters if you’re simultaneously job searching and still doing your current job, where you’re running sales calls or attending product meetings that could also benefit from live AI support.
The response time guarantee is specific. Craqly processes locally, which is how it achieves consistent sub-3-second responses even during complex technical questions. That’s not just a marketing claim. It shows up in practice during multi-part system design questions where the tool needs to process a long prompt and return something useful before the interviewer expects you to start talking.
When free is genuinely enough
If you’re doing a handful of junior-level behavioral interviews and you mostly need basic talking-point reminders, Last Round AI will probably serve you fine. The real-time suggestions for standard questions like “walk me through your background” or “how do you handle conflict” don’t require sophisticated infrastructure. Any tool with basic LLM integration can surface decent answers to those questions.
Also, if you’re broke. I don’t mean that dismissively. Job searching while unemployed has a real budget dimension, and “use the free tool, upgrade once you have an offer” is a completely legitimate strategy. The free tier on Craqly exists for exactly that situation, but if even a modest paid subscription is off the table, Last Round AI gives you something to work with.
When you need more
Technical interviews are where the gap shows up most clearly. If you’re doing a system design round at a Series B or later, or a coding screen at a company with a competitive process, the quality of real-time suggestions matters more. You need accurate code suggestions in the language the interviewer expects, fast enough that you can use them naturally. You need context retention across a 90-minute final round, not just isolated answers to individual questions.
Mock interview quality also matters for preparation. Craqly’s mock interview product gives you realistic feedback on your answers. I don’t have direct comparison data on Last Round AI’s mock interview feature, and I’d want to see more before making a strong claim about how they compare there.
The 2024 Stack Overflow Developer Survey found that 62% of professional developers are actively using AI tools during their work, with that number higher among developers at companies under 100 people. Interview AI tools are a natural extension of that workflow shift. As more candidates start using these tools, the ones with stronger underlying infrastructure will start producing meaningfully better results.
The transparency gap
Craqly’s documentation explains their architecture, their model choices, and their local processing approach. You can make an informed decision about what you’re running. Last Round AI’s site is considerably thinner on technical detail. This might improve over time. Right now, it makes it hard to evaluate how the tool performs under the specific conditions that matter for your interviews.
For a casual 30-minute phone screen, this gap probably doesn’t matter. For a 4-hour onsite loop at a company you really want to work at, I’d want to know more about what I was trusting with my performance.
The straightforward comparison
Use Last Round AI if: cost is the primary factor, you’re doing entry-level or standard behavioral interviews, and you’re comfortable with limited information about the tool’s capabilities.
Use Craqly if: you’re doing technical interviews, you want consistent response times you can rely on, you want a free trial that shows you the real product before you commit, or you want a single tool that covers interviews and your current job’s meeting and sales workflows.
According to LinkedIn’s Economic Graph research, AI-related skills are now among the fastest-growing in job postings across industries. Knowing how to use these tools effectively during the hiring process itself is becoming a real differentiator. The question isn’t whether to use AI interview assistance. It’s whether the specific tool you pick actually performs when it matters.
