Sider: AI Research Agent & Extension Reviews

Reviewers mostly see Sider as a practical, browser-based AI helper that saves time on research, email drafting, grammar, idea generation, and simplifying technical text. The most repeated praise is its tight browser integration, broad feature set, and source-scanning summaries, with some users also noting fast updates and responsive community support. The main complaints are less about core usefulness than about pricing and plan limits: several users want clearer usage rules, and one sharply negative review says “unlimited” access still felt heavily restricted and refund handling was poor.
