AI interview assistant for Mac

Co-Help on macOS

Co-Help supports macOS 12 and later, on both Apple Silicon (M1 and newer) and Intel Macs. It's the same app and the same feature set as the Windows version: a private overlay with screen-capture protection, live transcription, screenshot Q&A, practice mode, GitHub-connected answers, and answers from Anthropic Claude with OpenAI GPT as automatic fallback.

Windows 10 and 11 are also fully supported if you interview from a Windows machine — Co-Help works the same way on both.

Installing Co-Help on a Mac

1. Download the DMG. Download free and choose "Download for Mac" and pick Apple Silicon or Intel to match your machine.
2. Install. Open the .dmg and drag Co-Help into Applications.
3. Grant permissions. macOS requires you to allow Screen Recording and Microphone access in System Settings so Co-Help can capture your call's system audio and render its overlay.
4. Sign in and go. Use the email you paid with — access activates automatically, and you're ready for your first session.

Apple Silicon or Intel — does it matter?

Co-Help ships builds for both Apple Silicon and Intel Macs, so performance is native either way rather than running through emulation. Pick the download that matches your Mac's chip on the free download page. Choose and pay for a plan after creating your account in the app.

Screen-capture protection on a Mac

Co-Help’s overlay is a click-through window that asks macOS to exclude it from screen capture. In typical Zoom, Microsoft Teams and Google Meet screen shares it does not appear, while it stays visible to you on your own display. This depends on your OS version and settings, the meeting, recording or proctoring software, and your hardware, so it is not guaranteed — never assume the overlay is invisible, and follow the rules of every interview you use Co-Help in (see our Terms). It works the same way as on Windows.

Pricing for every interview type

The same three plans cover every interview type — there's no separate add-on for coding, system design, or behavioral support:

• Free 15-minute trial — Pro Max features, no card needed. The clock starts at your first question.
• Pro — $10 per session, 5 for $39, $79 for 30 days or $349 a year: fast models, sessions up to 90 minutes, no screenshots or diagrams.
• Pro Max — $20 per session, 5 for $75, $150 for 30 days or $600 a year: the most advanced models, screenshots and diagrams, sessions up to 2 hours.

Every plan includes humanized answers from Anthropic Claude with OpenAI GPT as automatic fallback, live transcription, answers from your documents and knowledge base, GitHub-connected answers, 20+ languages, the phone companion and the private overlay with screen-capture protection — with no API keys to manage. Screenshot Q&A and diagram rendering are Pro Max features.

Practice first, then live help where it's allowed

• Practice mode. Run a behavioral, coding or system design mock interview for the role and seniority you choose. Answer by typing, or out loud with a voice interviewer that reads each question and can ask a follow-up (voice practice is tailored to a job description you paste in). Each answer gets a 1–10 score against a rubric, written feedback, strengths, areas to improve and a model answer, and you can download each report as a Markdown file. Practice is included with paid plans (unlimited on 30-day and yearly plans) and doesn't use up a live session. See AI mock interview practice.
• Live help, where it's allowed. In interviews and calls that permit AI assistance, Co-Help transcribes both sides and suggests answers on a private overlay on your Mac, drawing on your resume, projects and notes.
• Check the rules. Many employers, schools and testing platforms don't allow AI help. You're responsible for following them. Read the acceptable-use terms and Is it OK to use AI in an interview?

GitHub-connected answers. Connect GitHub with a personal access token and Co-Help indexes your repositories, so when an interviewer asks about your own projects, technical answers are grounded in your actual code instead of a generic guess. After each call, your session report and history let you review the questions and answers.
