Arco
Choose from 400+ AI models & compare side by side on Mac
Arco is a native Mac app for chatting with and comparing AI models side by side, with access to 400+ models through OpenRouter. Bring your own key, pay providers directly with no markup, and keep every conversation local on your Mac. When a new model comes out, you can add it to Arco the same day. No monthly subscription. Free to download.
Hey! 👋
I'm Manoj. I built Arco because I got tired of opening ChatGPT, Claude, and Gemini in three tabs, pasting the same prompt three times, and trying to spot the differences myself while making a decision.
I also tried the other multi-model tools out there (ChatHub, Poe and ChatPlayground). The problem with all of them is the monthly subscription. I don't use this kind of tool every day, so paying a flat fee every month felt off.
The credit-based solutions drained fast.
So I made Arco work differently:
🔑 Bring your own OpenRouter key. You pay them directly, and you get all 400+ models they support, including the ones that just came out this week.
🔒 Your chats stay on your Mac. Only you can see them.
💸 No monthly subscription. Free to download with everything included.
🍎 Made for Mac. Apple Silicon, macOS 13+ required.
I'd love your feedback. What would make this more helpful for you? Especially curious to hear from anyone who's tried ChatHub, Poe, or ChatPlayground and felt like something was missing.
