AI Resume
Write your resume around the target job description.
After you upload an old resume or fill in your experience, AI automatically adjusts the focus to your target job description, rewrites the wording, fills in quantified results, and offers section-by-section revision suggestions.
- One-click JD tailoring: switch roles to shift the focus
- Quantification tip: change "responsible for" to "increased X by N%"
- Real-time quality scoring, with each item clickable to edit
AI mock interview
Practice interviews through lifelike conversations with AI.
Once you pick a position, AI questions, follows up, and stress-tests you in an interviewer's voice; after each session it automatically generates a question-by-question review, improvement suggestions, and focus areas for next time.
- Text / voice dual modes, at your own pace
- Multi-round follow-ups that simulate real high-pressure interviews
- Structured review: which questions you tackled head-on and which you dodged
DESKTOP · Real interview scenarios
During the real interview, the desktop app sits right beside you.
Invisible to screen sharing + system audio capture + live screen reading — three desktop powers built for the interview itself.
interview copilot
Listens to questions in real time and gives answer ideas in seconds.
Keep the client running during a video interview: it captures the interviewer's questions, recognizes them locally, and hands you an approach, keywords, and an opening line. The window hugs the screen edge with adjustable opacity, and stays invisible to screen sharing and recording — even when you share your whole screen.
- System audio capture (won't grab your interview software's microphone)
- Invisible to screen sharing and recording (OS-level capture protection)
- Answers built around your resume + job description context
Coding-test assist
Online coding-test questions, with solution ideas in seconds.
Screenshot the current question, and AI automatically interprets it, outlines the solution steps, generates reference code in the relevant language, and annotates the complexity. Everything runs locally—the original question text is never sent externally.
- Multiple languages: JS / TS / Python / Java / C++ / Go / Rust
- Solution approach + code + complexity, side by side
- Supports online platforms like Nowcoder / LeetCode / Codility
Supports macOS 12+ · Windows 10/11 · Linux
MULTI-DEVICE · Connected across devices
Main screen on your computer, prompts on your phone.
Run the video call on your main screen and read AI prompts on your phone as a second screen — the prompts never enter any shared view, so the interviewer can't see them.
Desktop: full interview assistance
System audio capture, screen recognition, edge-docked transparent window—this is the main arena.
Mobile: a "sideline prompter"
Keep it within reach to see AI talking points + keywords—more natural than glancing at your computer screen.
Scan to pair—no need to sign in again
Scan with your phone to auto-pair with the current computer session, and AI prompts push to it in sync.

What makes Kuaimian different from other AI interview tools?
Kuaimian turns interview prep from "grinding question banks" into "preparing around your target job description". Every feature (resume optimization, mock interviews, interview copilot) shares the same position context, so the output automatically matches the tone and evaluation criteria of your target company and role.
Can I use it without an existing resume?
Yes. Kuaimian lets you fill in your experience directly and structures it into a resume automatically; you can also upload an old resume (PDF / Word) for AI to parse and optimize.
Is the mock interview text or voice?
Both. You can type to practice phrasing or speak to practice verbal delivery — the pace is entirely up to you.
Will the interviewer notice the copilot?
The desktop app is a frameless transparent window with system-level capture protection for screen sharing and recording — even sharing your whole screen, Kuaimian never appears in the interviewer's view or recordings.
How does it recognize coding questions?
Just screenshot the current problem — the AI OCRs the statement and understands the inputs, outputs, and constraints, no manual transcription needed.
Will the interviewer notice the interview copilot?
The desktop app is a frameless transparent window with system-level capture protection for screen sharing and recording (native Windows / macOS capabilities) — even if you share your entire screen, Kuaimian never appears in the interviewer's view. System audio capture happens entirely on your machine; your microphone audio is never sent anywhere.
Can one resume produce multiple versions for different roles?
Yes. Start from one base draft and paste different job descriptions to derive tailored versions — applications to different companies stay independent.
Does the AI ask questions based on my resume and role?
Yes. Kuaimian designs the question line around the projects in your resume and your target job description, from behavioral to technical, and follows up on your answers.
