Cheetah is an AI-powered macOS app designed to assist users during remote software engineering interviews by providing real-time, discreet coaching and live coding platform integration.
With Cheetah, you can improve your interview performance and increase your chances of landing that $300k SWE job, without spending your weekends cramming leetcode challenges and memorizing algorithms you’ll never use.
How it works
Cheetah leverages Whisper for real-time audio transcription and GPT-4 for generating hints and solutions. You need to have your own OpenAI API key to use the app. If you don’t have access to GPT-4, gpt-3.5-turbo may be used as an alternative.
Whisper runs locally on your system, utilizing Georgi Gerganov’s whisper.cpp. A recent M1 or M2 Mac is required for optimal performance.
Requires macOS 13.1 or later.
SDL2 must be installed or the app will crash on launch:
brew install sdl2
Audio driver setup
For the best results, ensure the audio input captures both sides of the conversation.
When using a video chat app like Zoom or Google Meet, you can achieve this with BlackHole, a free audio loopback driver. Follow the instructions for setting up a Multi-Output Device, and remember not to use the loopback device as input for the video chat app.
Open the app and select an audio input to start live transcription. A snippet of the transcription will be displayed under the audio input selector.
Note: running the app in debug mode will result in very slow audio transcription performance.
The UI features three buttons:
Answer: Generates an answer for the interviewer’s question.
Refine: Updates the existing answer, useful for when the interviewer provides additional constraints or clarification.
Analyze: Analyzes code and logs from the live coding environment in your web browser. Requires the browser extension.
You can also select (highlight) a portion of a generated answer and click Refine to get more detail.
Installing the browser extension
Currently, only Firefox is supported. Follow these steps to install the extension:
- Add the domain of the live coding platform to
- Go to about:debugging
- Click “This Firefox”
- Click “Load Temporary Add-on”
- Select ./extension/manifest.json
