Viktor Korobov’s note
I've been using ChatGPT, Claude, Gemini, and recently Kimi. Each has its strengths, but Kimi's ability to work with long context is particularly impressive. It's definitely a tool I'd recommend trying if you often deal with large documents or complex coding tasks.

Viktor Korobov’s note
GitHub Copilot doesn't replace a developer, but it removes a lot of repetitive work. I find it most useful for generating boilerplate code, suggesting functions, and keeping me focused while coding.

Viktor Korobov’s note
Cursor is probably the biggest productivity boost I've had as a developer in years. Having an AI that understands the entire codebase instead of just the current file makes a huge difference. It feels less like an autocomplete tool and more like working with a knowledgeable teammate.
