The verdict

SciSpace wins, 6.9 to 6.8

SciSpace reads figures and tables inside papers, something AnswerThis cannot do, and its cheapest paid plan, Premium, costs $20 a month against AnswerThis's $35. SciSpace also ships a mobile app and works in more than 75 languages, both absent from AnswerThis. AnswerThis pulls ahead for a systematic review: it screens papers with include and exclude decisions, builds a PRISMA flow diagram and runs a risk of bias assessment, none of which SciSpace offers.

Pick AnswerThis if you need PRISMA and risk of bias for a systematic review.

Pick SciSpace if you need figure reading, a mobile app or non-English support.
