ExtraBrain vs Cluely: Choosing a Responsible AI Interview Assistant

Comparing AI interview assistants for real interviews

Candidates want an AI interview assistant that helps them stay organized, calm, and clear during high-pressure conversations. The real question is not only which assistant can provide fast suggestions. The better question is which assistant fits the interview rules, protects sensitive context, and supports genuine thinking instead of replacing it.

ExtraBrain is a free, local-first Mac desktop AI interview assistant and meeting copilot. It combines live transcription, screen-aware context, local Gemma 4 on-device AI where installed and compatible, bring-your-own AI providers, and privacy controls. Cluely is often discussed as a broad real-time assistant for calls, meetings, and screen-based work. This comparison focuses on how a candidate should evaluate tools like these for interviews, meetings, technical rounds, and preparation workflows.

Use any AI interview copilot only where your interview, employer, school, workplace, meeting, and platform rules allow AI assistance, transcription, screenshots, or notes. If the rules are unclear, ask before using it. A tool can be technically capable and still be the wrong choice for a particular interview if it violates the expectations of that process.

What an AI interview assistant should do

An AI interview assistant helps candidates follow live context and produce better structured responses. It can transcribe questions, summarize what has already been discussed, surface relevant details from the screen, suggest clarifying questions, and help organize an answer before the candidate speaks.

The best use of this category is not to outsource honesty or judgment. It is to reduce panic, catch missed context, and help candidates communicate the experience they already have. That distinction matters most in coding interviews, system design rounds, case interviews, and behavioral conversations where trust is part of the evaluation.

Core capabilities to evaluate

A useful AI interview copilot should help with several practical tasks:

• Capturing the interviewer question accurately.
• Keeping track of follow-up constraints and examples.
• Helping turn scattered thoughts into a concise answer structure.
• Supporting technical tradeoff analysis without pretending certainty.
• Suggesting clarifying questions when the prompt is ambiguous.
• Preserving transcripts and notes for post-interview review when allowed.
• Giving the user clear control over what data stays local and what data may be sent to external providers.

ExtraBrain is designed around this full workflow. It can support live sessions, transcripts, notes, screen context, and after-session review in a focused second-brain-style workspace for interviews and meetings.

ExtraBrain overview

Local-first Mac desktop workflow

ExtraBrain runs as a Mac desktop app for Apple Silicon and Intel Macs. It is built for candidates who want interview support without turning the interview into a browser-tab juggling exercise. The app can combine live transcription with screen-aware context so the assistant can reason about both what is being said and what is visible on the screen.

This matters in technical interviews because the prompt is often split across multiple places. A coding exercise may include spoken constraints, code editor state, terminal output, and follow-up questions. A system design interview may include a diagram, a short written prompt, and a live discussion about traffic, consistency, and scaling. A behavioral interview may include a vague question where the candidate needs to choose the right story and structure it clearly.

Privacy controls and local options

ExtraBrain’s local-first posture is one of its most important differences. With local Parakeet transcription plus local Gemma 4 on-device AI where installed and compatible, transcription and AI prompts can stay local. Local Gemma 4 requires installation and compatible hardware, so it may not be available on every Mac or customer environment.

ExtraBrain also supports bring-your-own external providers. This can include Anthropic, OpenAI, custom OpenAI-compatible endpoints, Claude Subscription, and Codex Subscription. When external providers are selected, prompts, transcript text, screenshots, audio, or other context may leave the device depending on configuration. That makes provider choice and session settings part of responsible use, not just technical setup.

Real-time interview support

ExtraBrain can help generate answer outlines, STAR structures, technical explanations, and follow-up questions from live transcript and screen context. It can support coding interviews, system design rounds, behavioral interviews, product interviews, customer calls, lectures, and research meetings.

For example, during a coding interview, ExtraBrain can help the candidate restate the problem, identify edge cases, explain complexity, and keep track of constraints. During a system design interview, it can help structure requirements, APIs, storage choices, bottlenecks, tradeoffs, and follow-up questions. During a behavioral interview, it can help the candidate map a story into situation, task, action, result, and reflection.

The candidate still owns the answer. ExtraBrain is most useful when it helps someone express their real experience more clearly, not when it is used to misrepresent ability.

Cluely overview

Broad live assistance

Cluely is commonly discussed as a general real-time assistant for calls, meetings, and on-screen work. That broader positioning can be useful for people who want a helper across many scenarios, not only interviews. A broad assistant may help with summaries, reminders, writing support, sales calls, or general productivity tasks.

For interviews, breadth can be both helpful and limiting. A general assistant may be convenient when you want one tool for many workflows. A focused interview assistant may be stronger when you need coding, system design, behavioral answer structure, transcript review, and interview-specific context.

Questions to ask before using any broad assistant

Before using any broad live assistant in an interview, review these points:

• Does the interview or assessment explicitly allow AI assistance?
• Does the tool record audio, screenshots, screen content, or transcripts?
• Can you control which provider receives data?
• Can you turn features off quickly if the interviewer changes the rules?
• Does the product explain how data is stored, processed, and deleted?
• Does the assistant help you think, or does it tempt you to read answers you cannot explain?

These questions matter regardless of the brand. In high-stakes interviews, privacy and permission are part of professionalism.

Stealth, discretion, and responsible use

The original appeal of this tool category often centers on whether the assistant is visible during screen sharing or recording. ExtraBrain is designed to stay hidden from screen sharing and screen recording on major meeting tools, but that does not remove the user’s responsibility to follow the rules. Discreet interface behavior is useful for reducing visual clutter and protecting private notes. It should not be treated as permission to bypass interview, school, workplace, or platform expectations.

A responsible candidate should think about three layers:

1. Permission: Is AI assistance, transcription, screenshot use, or note-taking allowed?
2. Privacy: What data is captured, where is it processed, and who can access it?
3. Integrity: Can you explain and stand behind the answer you give?

If the answer to any of these is uncertain, use the assistant for preparation and post-interview review instead of live help.

ExtraBrain vs Cluely by interview scenario

Coding interviews

Coding interviews test more than the final code. They test problem understanding, edge cases, reasoning, communication, and debugging under pressure.

ExtraBrain is well suited to this scenario because it can combine transcript context with screen-aware context. A candidate can use it to organize thoughts, clarify constraints, compare approaches, and explain tradeoffs. If local Gemma 4 is installed and compatible, a local-first setup can keep prompts and transcription local when paired with local Parakeet transcription.

A broad assistant can still be useful if it helps summarize the problem or maintain context. However, candidates should avoid reading generated code they do not understand. The strongest interview performance comes from using AI support to improve communication, not to fake competence.

System design interviews

System design interviews are often messy. The candidate has to gather requirements, define assumptions, sketch architecture, compare storage choices, reason about scaling, and adjust based on interviewer feedback.

ExtraBrain can help by keeping the conversation organized and turning scattered signals into a structured plan. It can suggest clarifying questions such as expected read-write ratio, latency goals, consistency requirements, data retention, and failure modes. It can also help the candidate remember to discuss tradeoffs instead of jumping straight into a diagram.

A general assistant can be helpful for quick reminders, but the best system design support needs context from the transcript and the screen. That is where an interview-focused desktop workflow becomes valuable.

Behavioral interviews

Behavioral interviews reward specific, honest stories. A candidate usually needs to choose an example, frame it clearly, and connect it to the role.

ExtraBrain can help create a STAR outline from live context or preparation notes. It can also help the candidate avoid rambling by keeping the answer focused on the situation, task, action, result, and lesson learned. This is especially helpful for mid-career and senior candidates who have many stories but struggle to pick the right one quickly.

The assistant should not invent accomplishments. A strong behavioral answer depends on the candidate’s real experience.

Meetings, lectures, and research calls

If your main need is not only interviews, both types of assistants can be relevant. ExtraBrain is also a meeting copilot and can support customer calls, lectures, research meetings, and post-session review. The same transcript and context workflow that helps in interviews can help capture decisions, questions, action items, and follow-up notes.

A broader assistant may also fit everyday calls and solo work. The deciding factor is whether you want a focused local-first desktop workflow with provider control, or a more general assistant experience.

Pricing and platform considerations

ExtraBrain’s core Mac app is free. ExtraBrain Pro is $9.99 per month regular with $6.99 per month Founder pricing, $79 per year, or $149 Lifetime launch pricing. External AI and transcription provider usage is billed separately by the providers users choose.

ExtraBrain supports macOS today, including Apple Silicon and Intel Macs. Windows and Linux are planned future platforms. If you need support on another operating system right now, confirm current availability before choosing a tool.

Do not compare tools only on subscription price. For interview use, the bigger questions are whether the tool fits your platform, whether the privacy model matches your needs, whether the provider setup is clear, and whether the workflow helps you answer more honestly and effectively.

How to choose the right AI interview assistant

Choose ExtraBrain if

ExtraBrain is a strong fit if you:

• Use a Mac and want a desktop AI interview assistant.
• Want live transcription plus screen-aware context.
• Need support for coding, system design, behavioral, product, or meeting workflows.
• Want local-first options with local Parakeet transcription and local Gemma 4 where installed and compatible.
• Prefer bring-your-own provider control.
• Want a free core app with optional Pro features.
• Care about reviewing transcripts and notes after the session.

Consider a broader assistant if

A broader live assistant may fit better if you:

• Want one tool mainly for general calls, solo work, and everyday productivity.
• Do not need interview-specific workflows.
• Are comfortable with its current privacy model and platform support.
• Have confirmed that its use is allowed in your interview or meeting context.

A practical decision checklist

Before using any AI interview assistant, answer these questions:

1. Is AI assistance allowed in this interview or meeting?
2. Do I need live help, preparation help, or post-session review?
3. What data will the assistant capture?
4. Can I keep transcription and AI processing local if needed?
5. Which provider receives prompts, screenshots, transcript text, or audio?
6. Can I explain every answer I give without the assistant?
7. Does the tool reduce anxiety without reducing honesty?

If you can answer these clearly, you are more likely to use the tool well. If you cannot, use the assistant for practice rather than live interview support.
