Worth keeping as a private, ad-free second opinion next to Google, and it genuinely predates most of the AI-search wave. Answer depth and follow-up reasoning still sit behind Perplexity; the new usage-priced Search API and MCP server make the same index usable from code, though its rate card is not published up front.
Pros
- Free with no ads, no sign-up and no personal-data tracking
- Chrome extension and PWA make it easy to set as the default engine
- Answers carry source citations and low-quality pages are filtered out
- Search API and remote MCP server expose the same index to developers
Cons
- Small team competing against very well-funded rivals
- No team workspace, export or saved-research features in the consumer app
- Handles complex, chained questions less well than Perplexity
- API pricing is outcome-based with no published per-query rate card
