Our Journey

Side Copilot is a smart browser assistant for anyone who spends the day jumping from one tab to another. It stays neat with a clean side panel, puts tasks into clear sections, and uses AI to help you research and take quick actions, so you can focus without drowning in too many tabs. With BYOK, you’re not stuck with just one AI vendor. You can use your own API key and the model provider you already trust, which can help you manage costs, protect privacy, and keep performance strong. I’m also on the Lifetime Plan, I love the Shortcuts Templates and the price feels reasonable, so it’s a smart choice for the long run.

Side Copilot already helps, but it would be even better with a simpler layout, better options to customize it, and clearer controls for the AI model.

Side Copilot feels less like a basic tab organizer and more like a browser workspace built with AI. It adds a side panel, Spaces, shortcuts, and BYOK support, so it’s a better choice if you want to automate tasks, get research help, and stay in control of your AI provider.

I tried this product and to my surprise it has been a game changer to my tab productivity. The free plan is generous but I may just buy the paid plan to support the product. Very well put together. Looking forward to the G-drive integration. Thanks for building this!

This is perfect for grouping tabs. It makes sorting tabs using AI. I love it.
