FEATURES

Everything you need to move faster

Built for the way you actually work. No tab-switching, no copy-pasting.

EXCLUSIVE
📐

System Design Mode

Press one hotkey on a system-design screenshot — get a full architecture analysis with rendered Mermaid diagrams (flowchart, sequence, ER) inline. No competitor draws diagrams in the answer.

EXCLUSIVE
🎧

Speaker Mode

Listens to your interviewer through your speaker, transcribes in real time, and answers with one tight sentence the moment you toggle off. Perfect for verbal warm-ups and behavioral rounds.

📸

Screenshot AI

Hotkey-capture your screen. AI reads the code, the LeetCode prompt, the design doc — and walks you through the answer in milliseconds.

🧠

Conversation memory

Follow-up questions remember the full thread. Ask "now make it O(n)" and it knows what came before.

🔲

Stealth overlay

Always-on-top transparent window with click-through mode. Hidden from the taskbar. Toggle invisible during screen-share with one keystroke.

Latest models

GPT-5 Mini, GPT-5, Claude Sonnet 4.6, Claude Opus 4.7 — switch in one click.

🔑

Bring your own key

Use your own OpenAI or Anthropic key — calls go directly from your machine, never through our servers.

⌨️

Custom hotkeys

Every action has a keyboard shortcut. Rebind anything in Settings.

🔒

Privacy first

Screenshots and audio never logged by default. Local-only mode available.

HOW IT WORKS

Three keystrokes. One answer.

1

Capture

Press Ctrl+1 to screenshot, Ctrl+Shift+A for the speaker, Ctrl+Shift+S for system-design mode — or just type.

2

Ask

AI sees the screenshot, hears the speaker, and knows the full thread. Switch modes mid-conversation.

3

Answer

Streaming response with full Mermaid diagrams for system design. One-sentence verbal answers in speaker mode.

WHY NOT JUST USE CHATGPT?

Interview Helpers vs general AI tools

ChatGPT and Cursor are great general-purpose tools. They aren't built for the live-interview workflow.

If you're prepping by yourself with notes and time, ChatGPT is fine. If you're in a live interview and need answers in seconds, you want a tool built for it.
