When to stay with Undermind
Documented strengths from our Undermind review — switching isn't always the right call:
- Recall-oriented design finds papers that keyword search and one-shot retrieval tools miss on narrow topics
- Academic pricing at $16/month annually is cheap relative to a single journal article purchase
- Free tier runs real deep searches rather than a crippled demo, making evaluation genuine
