Questions about Sider
What is Sider?
Sider is an AI sidebar for everything a person does in the browser. It summarizes long pages, lets users chat with several AI models including GPT, Claude, Gemini and Grok, translates webpages into multiple languages, and can fill out forms or compare prices automatically while shopping.
How much does Sider cost?
Sider has a limited free tier at $0, and paid use starts at $19 per month. Toolio notes that the free plan includes all features but has limited credits for AI interactions, and the reviewer warns that paying users may face additional charges beyond the basic features.
Does Sider have a mobile app?
No. Sider runs on the web, and the reviewer notes there is no mobile app yet, since it is currently only available in the browser. For that reason Toolio lists it as not for travelers with frequent mobile needs.
