Let's talk features, because that's where it shines. The global hotkey-Cmd + Space by default-pops open a clean chat window in seconds. You type away, and it taps into OpenAI's API for responses, keeping the whole conversation context-aware so follow-ups make sense. Privacy is huge here; everything processes locally on your Mac, no data zipping off to servers you don't trust.
And since it's open-source, I remember tweaking the hotkey myself when it clashed with another app-super straightforward on GitHub. It's lightweight too, sips resources even on my older MacBook, unlike some bloated extensions that slow everything down. Who's this for, exactly? Well, in my experience, it's perfect for writers like me outlining posts or brainstorming SEO strategies on the fly.
Developers debugging code snippets without leaving their IDE, marketers whipping up copy, or even students researching topics mid-study session. I mean, last week I used it to explain a tricky algorithm to a client-real time saver. But it's not just pros; casual users tinkering with ideas will dig it too.
If you're on Windows, though, that's a bummer-it's Mac-only for now, which limits things a bit. What sets Sidekick apart from, say, the official ChatGPT app or Raycast? It's more native-feeling, no ads or subscriptions beyond your API key, and way less resource-hungry. I was torn between it and browser extensions at first, but the seamless integration won me over; or rather, the lack of distractions did.
Unlike bulkier options, it just gets out of your way and lets you work. All in all, if quick AI access sounds appealing, grab Sidekick from their site, snag a free OpenAI key, and test it out. You'll probably wonder how you coped without it-trust me, it streamlines those daily brain dumps like nothing else.
