Question 1

What is Interview Helpers?

Accepted Answer

A stealth desktop overlay built specifically for tech interviews. Take a screenshot of a coding problem and get a streaming answer in seconds, switch to System Design mode for full Mermaid architecture diagrams, or toggle Speaker Mode to listen to your interviewer's voice and get one-sentence verbal answers. Always-on-top, transparent, hidden from the Windows taskbar.

Question 2

How does the free trial work?

Accepted Answer

You get 10 free AI messages — no credit card, no time limit. Once you use them up, subscribe monthly or annually to keep going.

Question 3

What platforms are supported?

Accepted Answer

Windows 10 or later (64-bit).

Question 4

I have a LeetCode / coding problem on screen. How do I get an answer?

Accepted Answer

Press Ctrl+1. Interview Helpers captures your active screen, sends it to the AI, and starts streaming the answer in the chat panel. If you want to add a typed hint first ("focus on time complexity"), type it in the box and then hit Ctrl+1 — your text is used as the question instead of the default. Press Esc to cancel mid-stream, Home to clear the chat between questions.

Question 5

My interviewer is asking a system-design question. How do I get a diagram?

Accepted Answer

Step 1: press Ctrl+Shift+S to turn on System Design Mode (you'll see a blue "SYSTEM DESIGN" badge in the title bar). Step 2: press Ctrl+1 to send your screenshot. The AI responds with a structured architecture answer including a high-level Mermaid flowchart, a sequence diagram, and an ER data model — all rendered inline as SVG, no external tool needed. Press Ctrl+Shift+S again to switch back to coding mode.

Question 6

My interviewer is asking a verbal theory question (e.g., "what's a Bloom filter"). How do I get a one-sentence answer?

Accepted Answer

Press Ctrl+Shift+A to start Speaker Mode. Live transcription of your interviewer's voice appears above the chat input, in real time, with no latency. When they finish the question, press Ctrl+Shift+A again — the transcript is sent to the AI, which responds with a single tight sentence you can read out loud while they're still saying "good question." Use this for theory Q&A, behavioral warm-ups, and definition checks.

Question 7

How do I hide the app instantly if my interviewer asks for a full screen-share?

Accepted Answer

Press Ctrl+Shift+U. The window disappears completely. Press Ctrl+Shift+U again to bring it back. Note that the app is already hidden from the Windows taskbar AND invisible to OS-level screen capture (Zoom, Teams, Meet, screenshot tools), so this hotkey is a panic-button rather than a daily necessity.

Question 8

How do I make the overlay see-through during the interview?

Accepted Answer

Press Ctrl+G. The window drops to 40% opacity and becomes click-through (your mouse passes through to the IDE underneath). Press Ctrl+G again to come back to full opacity and reclaim mouse focus. Use this when you want to read the AI's answer while staying focused on the interviewer's screen-share underneath.

Question 9

How do I clear the chat between questions?

Accepted Answer

Press Home. The thread resets to a fresh conversation. Use this between interview questions so the AI doesn't mix context from earlier rounds.

Question 10

How do I move the overlay window?

Accepted Answer

Ctrl + Up / Down / Left / Right move the window 50 px in that direction. The window is clamped to your screen — it can't drift off-display. You can also drag it by the title bar.

Question 11

Can I rebind the hotkeys?

Accepted Answer

Yes. Open Settings → General → Hotkeys. Click any row, press your new combination. Changes apply immediately. If a combo conflicts with another running app, the registration silently fails — pick a different chord. Full reference at /docs/hotkeys.

Question 12

Which AI models do you support?

Accepted Answer

GPT-5 and Claude Sonnet 4.6 in the standard tier, GPT-5.4 and Claude Opus 4.7 in the premium tier. All four are included with your subscription — switch between them in one click in Settings → AI Model.

Question 13

Which model should I use?

Accepted Answer

GPT-5 for general questions and screenshots (fast, capable). Claude Sonnet 4.6 for nuanced reasoning. GPT-5.4 or Claude Opus 4.7 for the absolute hardest problems — slower but stronger.

Question 14

Are my screenshots stored?

Accepted Answer

No. Screenshots are sent to the AI model and immediately discarded. We never log raw images by default.

Question 15

Is my voice recorded?

Accepted Answer

Voice is transcribed in real time and the audio is discarded. Only the transcript is kept (and only if you choose to send the message).

Question 16

Where is my conversation data stored?

Accepted Answer

In our database (encrypted at rest) by default, so you can pick up where you left off. You can delete any conversation any time, or use local-only mode where nothing leaves your device.

Question 17

Can I cancel anytime?

Accepted Answer

Yes. Cancel from your account page or directly in the Stripe billing portal. You keep full access until the end of your current billing period — at that point, the subscription ends automatically.

Question 18

What's the difference between monthly and annual?

Accepted Answer

Monthly is $39/mo. Annual is $375/year (effectively $31.25/mo) — you save $93. Same features either way.

Question 19

Do you offer refunds?

Accepted Answer

No. You get 10 free messages to try every feature before paying. Once you subscribe, payments are final. You can cancel anytime to stop future renewals — your access continues until the end of the current billing period.

Question 20

What happens when I cancel?

Accepted Answer

You keep using all features until the end of your paid period (the renewal date). After that, your subscription ends automatically — no further charges, no further access.
