SideAI is a free Chrome extension that brings LLM chat capabilities to your browser sidebar. Modern UI, smooth animations, and connection to any LLM API.






Hey PHers! 👋
Tired of alt-tabbing like a maniac just to ask your AI assistant a quick question? Meet SideAI—a free, game-changing Chrome extension that brings any LLM (GPT-4, Claude, or your own API) right into your sidebar, so you can chat without ever leaving your workflow.
Why SideAI?
⚡ Always Free, No Paywall – Unlike other tools that nickel-and-dime you, SideAI is 100% free—forever. No subscriptions, no hidden fees.
⚡ No More Tab Hell – AI lives in your sidebar, not another tab. Research, code, or write without breaking focus.
⚡ Your AI, Your Rules – Use OpenAI, Anthropic, local LLMs, or any custom API. Full control, zero lock-in.
⚡ Token-Saving Modes – Toggle between single-turn (fresh context) and multi-turn (continuous chat) to optimize costs.
⚡ Custom Prompts & Personas – Pre-set prefixes, system prompts, or role-based behaviors for tailored responses.
Why I Built This
I was sick of paying for bloated AI apps just to copy-paste between tabs. SideAI is my answer: lightweight, free, and right where you need it.
🚀 Try it now—it’s free forever! Would love your thoughts to make it even better.
