In this video I tested DeepSider, an all-in-one AI sidebar extension that runs right inside your browser while you’re browsing. I showed you how to install it on Chrome (link in the description), add the extension, pin it, and open it as a sidebar. The main point is simple: instead of jumping between different AI websites, you get a single place to access a ton of models—image generation, video generation, search, and “thinking” models. I went through the model list and the advanced options so you can see how many choices you actually get. After signing up with email, you start with 200 free credits, so you can test it without paying. I used GPT-4 mini to generate a basic landing page (full HTML + CSS), then pasted it into Visual Studio to preview the result. The big takeaway is the cost side: DeepSider uses one subscription that covers 20+ models, with plans like $2.5/month for 10,000 credits, plus higher tiers for 30,000 and 60,000 credits. I also pointed out extra tools like file/data analysis and a translation feature that’s accurate because you can choose different models, and there’s a web version too with the same subscription.
