Sider

Free to use with usage limits; paid plans available

Price checked at source August 28, 2026.

A multi-model AI chat app for Mac — Gemini, Claude, Grok, and DeepSeek behind one sidebar-style interface, free to start with browser integration.

Our take

Less a single chatbot than a front end for several at once — Sider’s own listing describes combining Gemini, Claude, Grok, and DeepSeek for chat and image-based conversations, plus shortcut-triggered translate/rewrite/summarize actions on selected text and a Safari-integrated sidebar for in-browser use. One account covers the Mac app, the browser extensions, and mobile. The free tier’s usage limits for those bundled models aren’t detailed on the App Store listing itself — check sider.ai/pricing before counting on heavy daily use.
