Research AI tools — common questions
- How many research AI tools does the directory list?
- 3 active tools, including Elicit AI, NVIDIA BioNeMo and Perplexity AI. Each entry lists its category, pricing tier, starting price and what it is best for, so the set can be compared side by side rather than read one review at a time.
- Are there free research AI tools?
- Yes — 3 of the 3 have a free or freemium tier. That means a $0 way in, not necessarily a free product: the directory records where a free tier ends and what the first paid plan costs, because those are different facts.
- How much do research AI tools cost?
- Published prices run from $20 to $375 a month (yearly and per-seat prices converted to a monthly equivalent so they compare honestly). The cheapest paid option is Perplexity AI at $20/mo.
- Which research tool should I pick?
- That depends on the job, which is why every entry records one. Elicit AI is listed for Academic researchers, students, and professionals who need to quickly review scientific literature, extract key findings, and synthesize information efficiently; NVIDIA BioNeMo for Pharmaceutical companies and academic research institutions focused on accelerating the design and optimization of novel therapeutics using AI. We do not rank or score tools — there is no honest rating data behind a star, so the directory gives you the facts and the comparison instead.
