How it works

  1. Ask your questionClinical or research, in your language. We turn it into several searches with MeSH terms and synonyms.
  2. We search and readAbout 100 studies from three databases; the AI picks the most relevant and reads their design and size.
  3. You get an answer with citationsEvery claim carries its study. You see the conclusion and how many studies say yes, possibly, mixed or no.

Sources: PubMed, Europe PMC and OpenAlex. Citations to studies that were not found are removed before the answer is shown. More about the methodology →

What you will see

Your first answer is complete, in the same layout review teams use in SysRevAI. From the second one on, you will see:

  • The conclusion, with the studies behind it
  • The certainty and how far the studies agree
  • The consensus meter: yes, possibly, mixed or no
Example

Is flumazenil dangerous in a benzodiazepine overdose?

It is linked to more adverse events than placebo, mainly seizures; in selected patients it appears safe. Penninga 2016

Consensus meter
  • Yes 44%
  • Possibly 19%
  • Mixed 19%
  • No 18%

Frequently asked questions

Is it free?

Yes. Your first question shows the full analysis, without signing up; later ones show the conclusion, the certainty and the consensus meter. The full analysis of every question, without limits, is in SysRevAI, free for 30 days with no card.

Where do the answers come from?

From the abstracts of studies published in PubMed, Europe PMC and OpenAlex. The AI answers only from the studies it finds and cites every claim; citations to studies it did not find are removed.

Is this medical advice?

No. It summarises the published evidence to help professionals and researchers; it does not replace clinical judgement or seeing a professional.

What happens to my question?

It is kept anonymously to show you the answer. If you sign up on SysRevAI it moves to your account; otherwise it is deleted after 30 days.

What is SysRevAI?

An open-source platform for AI-assisted systematic reviews in the health sciences: screening, data extraction, risk of bias, GRADE and PRISMA, plus unlimited Ask the evidence.

Who is Evidencing for?

For healthcare professionals, researchers, teachers and health sciences students who need to know what research says about a clinical or health question. It searches biomedical databases (PubMed/MEDLINE, Europe PMC and OpenAlex) and is the first step towards a systematic review in SysRevAI.
