AI Curious delivers strong value for R&D groups and knowledge‑intensive teams that need fast, reliable literature mining. Its biggest strength is the end‑to‑end workflow—from discovery to structured output—saving dozens of hours per project. The primary limitation is incomplete coverage of subscription‑only journals, which may require supplemental manual searches. For mid‑size research departments, the Professional plan is a clear win; solo researchers may stay on the free tier if query volume is low.
