Three steps. One hotkey.
The entire workflow takes under 10 seconds. Here is exactly what happens.
Capture your screen with a hotkey
A global keyboard shortcut captures your screen from any application — full screen, a specific window, or text from your clipboard. Works on every monitor.
AI reads and analyzes the problem
The AI extracts the problem statement, identifies constraints, detects the language, and structures the problem before solving. Your screenshot goes directly to OpenAI or Anthropic from your machine — no middleman server.
Get a solution at your level of detail
Solutions stream in real time — you start reading before the model finishes. Choose your verbosity: Clean for just the code, Normal for a balanced breakdown, or Explanatory for line-by-line teaching. Copy to clipboard with one keystroke.
Same problem. 10x faster.
The ChatGPT copy-paste loop costs you 30-60 seconds every single time. Here is what the same task looks like with CodeAndSystem.

Select any region. Done.
One hotkey captures any part of your screen — IDE, browser, whiteboard, terminal. Multi-monitor support.
AI vision reads what you see
5 models across OpenAI and Anthropic extract your problem, constraints, and language from a screenshot. Auto-fallback across providers.
Recognizes your problem automatically
Detects LeetCode problems from your browser title and matches against a built-in catalog of 142 coding and 22 system design problems.
Your data. Zero middlemen.
Screenshots go straight from your machine to OpenAI or Anthropic. We never see, store, or touch your data.

CodeAndSystem does not replace LeetCode or Exponent — it replaces the workflow of copying problems into ChatGPT. You may still want a practice platform and a course alongside it.
Your data never touches our servers
Your data goes directly from your machine to your AI provider. Here is exactly how.
Your Machine
Screenshots are captured locally. The app reads your screen region and prepares the API request on your device.
Direct to Your AI Provider
The image is sent directly from your machine to OpenAI or Anthropic. It does not pass through our servers, proxies, or infrastructure.
Solution to You
The AI provider’s response comes straight back to your device. We have no access to the request, the response, or your API key.
