GPT + Grok (sometimes Claude) for writing docs, policies, requirements, client responses etc. Grok is often times more concise/direct, which helps me as I tend to be verbose. I always review/edit regardless. Much faster than writing from scratch, and combining responses on the same topic is sometimes best.

Copilot for code completion + reviews or small snippets/functions but larger code/module generation has been weak so far.

Claude for full modules generation or complex multi-file edits.

Research: Grok (less filtered + better search), Claude (complex dev topics), GPT (balanced but sometimes slanted and/or seems to favor certain sources).

My Teams: Mostly Copilot for code completion/reviews, mix of GPT/Claude for code. Last year was loose/experimental to learn but we plan to formalize guidelines more this quarter.

Definitely a ton of hype that doesn't always match reality, but it is a super powerful tool that really has made things move faster.
