AI coding interview assistant
Coding interviews usually mean sharing your editor on screen while you think out loud. Co-Help stays invisible through that screen share while helping you read, explain, and work through the problem.
How Co-Help helps with coding interviews
During a live coding interview, Co-Help listens to the interviewer's question through live transcription and can analyze what's on your screen — your code, a prompt, or test output — using screenshot Q&A. Take a screenshot of the problem or your current code, and Co-Help's 9 AI models race in parallel to explain it, suggest a next step, or spot a bug, appearing on your private overlay rather than anywhere the interviewer can see.
Because the overlay uses screen-capture protection, it stays invisible even while your code editor is the exact window being shared.
Built for the format
- Screenshot Q&A on your code editor — capture a function, error message, or prompt and get an explanation or suggestion instantly.
- Live transcription of the interviewer's question — so you don't have to hold every detail of a multi-part prompt in your head.
- Invisible on screen share — the overlay doesn't appear when your IDE or terminal is what's being shared.
- Your knowledge base — feed in past projects or notes so explanations connect to your real experience.
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:
- $20 one-time session — every feature, one full interview, no subscription.
- $150/month (40% off the regular $250) — unlimited sessions.
- $600/year (40% off the regular $1,000, about $50/month) — unlimited sessions, best value.
Every plan includes all 9 AI models, live transcription, screenshot Q&A, diagram rendering, your knowledge base, and the invisible overlay — with no API keys to manage.
Works on the platform you're interviewing on
Co-Help runs as a desktop overlay, independent of whichever video call tool your interview uses. It's invisible on screen share for Zoom, Microsoft Teams, and Google Meet alike, on both Windows and Mac.
Rules vary by employer and assessment platform. Some companies and technical-screen platforms explicitly restrict outside tools. Check the rules for your specific interview before using any AI assistant, including Co-Help.

Frequently asked questions
Does Co-Help work for coding and system design interviews?
Yes. Co-Help includes screenshot Q&A for reading code or diagrams and can render architecture and flow diagrams, alongside live transcription — useful for coding, system design, and behavioral interviews.
Can the interviewer see Co-Help while I share my code editor?
No. Co-Help's overlay uses screen-capture protection and a click-through window, so it doesn't appear in what's shared or recorded, even when your code editor itself is the shared window.
Does Co-Help support a specific programming language?
Co-Help's screenshot Q&A is powered by the same 9 AI models used across the app, which read and reason about whatever code or text appears in the screenshot rather than being limited to a fixed list of supported languages.
