Been doing interview prep for a while and the biggest friction point for me
was constant context switching — LeetCode tab, ChatGPT tab, docs tab, repeat.
So I spent the last few months building a solution. Here's what I learned:
The Capture → AI pattern is underrated
Instead of copy-pasting problem text into ChatGPT, a global shortcut that lets you draw a box on screen and pipe it straight to GPT/Claude vision is 10x faster. No reformatting, no switching apps.
Electron is actually great for this
Local desktop app means your API key never leaves your machine. No subscription, no server. Just your OpenAI/Anthropic key.
Focus mode changed how I study Hard blocking Cmd+Q during a timed session sounds extreme but it genuinely reduced my rage-quit sessions on hard problems.
Built it as MIT open source — happy to share the link in comments if anyone's interested. Also curious — what's your biggest friction point during interview prep?
