Sider: AI Research Agent & Extension Reviews

Reviewers mostly see Sider as a practical browser companion that saves time: they like how it scans many sources, summarizes key points, supports idea generation, and helps with everyday tasks like email drafting, grammar, and simplifying technical text. Users also praise the extension’s convenience, broad feature set, frequent updates, and responsive support. The main complaints are less about core usefulness than about cost and limits: some say pricing feels high, usage caps are unclear, and model access can be more restricted than expected, which left at least one buyer frustrated.
