AI Writer is listed as a separate writing tool inside the same workspace as the PDF chat and literature review tools.

SciSpace Agent
SciSpace Agent, Biomedical Agent and SciSpace Recruit are listed in the site menu alongside an Agent Gallery of ready-made agents.
What users say
Pros
- A ten-topic test of the first fifty results per search found no hallucinated references.
- Paper search results are more accurate than ChatGPT, returning fewer invented papers.
- Mapping out and describing journals saves days of initial prep work before reading full papers.
Cons
- Citation lists include non-existent journals, years, and authors, with some references entirely fabricated.
- Credits vanish within hours or a single task, and the agent costs far more than the subscription suggests.
- Annual plans renewed with no reminder email, and refunds were refused after the charges landed.
- Cancellation requests went unanswered while charges kept coming, and accounts could not be deleted.
- Upgrading to a monthly tier terminated the remaining months of a paid annual subscription.
- Basic searches returned no results or irrelevant journals, sometimes only a count of papers found.
