Sider: AI Research Agent & Extension Reviews

Reviewers mostly see Sider as a practical browser companion that speeds up research, reading, and everyday writing. They repeatedly praise the sidebar integration, multi-model access, source scanning, summarization, note organization through Wisebase, and responsive updates from the team. Several say it stands out against similar sidebar tools for packing many features into one extension. The main complaints are tighter-than-expected credit and model limits, unclear usage rules, occasional weak results, and pricing or refund frustration, especially around restricted access to premium models.
