Noah AI meters usage in credits, for example about 10 deep research tasks per month on Starter. It is focused on life science rather than general use, paid plans are shown as annual totals with no monthly price captured, and Team and Enterprise need contact. Basic is free with 300 credits on signup. Prices checked on 2026-10-02.
Perplexity starts at Education Pro, $10 per user per month for verified students and faculty, and has a free option. Gemini Notebook (formerly NotebookLM) has a free option; its price is not stated in our verified data. Neither is life-science specific in our pack.
