Best AI for Gastroenterology: Cited Answers on the Gut and Liver

Which AI tools answer gastroenterology and hepatology questions?

This guide compares the AI tools that gastroenterologists, hepatologists, GI fellows, nurses and students weigh for gut and liver questions, and each tool does a different job. AskMed is an AI medical reference that answers questions on upper GI bleeding, fatty liver disease, cirrhosis, pancreatitis, inflammatory bowel disease and H. pylori from journals, guidelines and drug labels, with a link after every claim, for anyone in medicine in any country. OpenEvidence is a clinical AI search engine for verified healthcare professionals, and its App Store listing says an NPI is required. UpToDate Expert AI is the AI companion to the UpToDate clinical reference and needs an UpToDate subscription with Expert AI enabled. ChatGPT is OpenAI's general chatbot. Much of what is called AI in gastroenterology, such as polyp detection during colonoscopy, AI scribes and endoscopy image software, is a different category and is left out here. The table shows what each tool is, where its answers come from and who can use it.

OpenEvidence

OpenEvidence describes itself on its US App Store listing as a clinical decision support platform and medical search engine for healthcare professionals. The listing names NEJM, JAMA, NCCN, Nature, the Cochrane Library and Wiley as official partners. It marks an NPI as required, says users must verify their healthcare professional status, and says the app contains advertising. OpenEvidence's Terms of Use say the service is not available in the European Union, the United Kingdom or the European Economic Area, so GI teams there need another tool. AskMed vs OpenEvidence compares the two in detail.

UpToDate Expert AI

UpToDate Expert AI is an AI-powered companion to the UpToDate clinical reference. Its App Store listing says answers are grounded in UpToDate content and linked to supporting sources, and that access needs an UpToDate subscription with Expert AI enabled, through an enterprise account or a personal subscription. It suits clinicians whose hospital already uses UpToDate. AskMed vs UpToDate Expert AI compares the two side by side.

ChatGPT

ChatGPT is OpenAI's general AI chatbot, on the web, iPhone and Android. It helps to talk a mechanism through or draft a patient leaflet on reflux, but it is not limited to medical sources, so check any clinical claim against the guideline first. OpenAI also runs ChatGPT for Clinicians, which its help center opens to verified US clinicians with an NPI and a license check. Is ChatGPT accurate for medical questions? covers what studies found.

How does AskMed answer a gut or liver question?

AskMed answers a gastroenterology or hepatology question in four steps, and you can check each one. First, AskMed rewrites the question as a medical search query, and for management questions it adds "latest guideline update" so the newest guidance is found. Second, AskMed searches a fixed list of medical sites, never the open web or forums; for the gut and liver, that list includes Gastroenterology, the American Gastroenterological Association's journal, plus PubMed, PubMed Central, NICE, WHO, CDC, NEJM, The Lancet, The BMJ, the Cochrane Library, the MSD Manual for professionals and BMJ Best Practice, and FDA and DailyMed drug labels. Third, AskMed ranks what it found: guidelines and health agencies first, then systematic reviews and meta-analyses, then reviews and references, then large trials, preferring work from the last 10 years. Fourth, an AI language model writes the answer with a link after every claim and gives the year of each guideline recommendation. If no usable source turns up, AskMed says that instead of answering from memory.

The AGA's living guidelines appear in Gastroenterology itself, such as its 2024 guideline on moderate-to-severe ulcerative colitis (doi). ACG guidelines in the American Journal of Gastroenterology, AASLD guidance in Hepatology and EASL guidelines in the Journal of Hepatology are not on AskMed's list of sites, so they reach AskMed through PubMed and PubMed Central. For evidence questions such as "Does early ERCP help in biliary pancreatitis without cholangitis?", Research Mode reads the most relevant source in full before it writes the answer. How AskMed answers lists every source.

Can AI help risk-stratify an upper GI bleed?

AI can help risk-stratify an upper GI bleed by explaining which score fits and what the guidelines do with the result, but the arithmetic is quicker on a calculator. The Glasgow-Blatchford score, published by Blatchford and colleagues in The Lancet in 2000 from 1,748 patients, uses only data available before endoscopy: blood urea, hemoglobin, systolic blood pressure, pulse, melena, syncope, liver disease and heart failure, for a total from 0 to 23. The 2021 ACG guideline on upper gastrointestinal and ulcer bleeding suggests risk assessment in the emergency department to find very-low-risk patients, such as those with a Glasgow-Blatchford score of 0–1, who may be discharged with outpatient follow-up, and suggests endoscopy within 24 hours of presentation for those admitted. The 2019 international consensus group made the same 0–1 suggestion. AskMed can set out that reasoning with its sources, and explain how the full Rockall score differs, since it needs endoscopic findings.

• Score it. The Glasgow-Blatchford score calculator adds the points from the 2000 paper and flags the 0–1 very-low-risk cut-off.
• Compare scores. Glasgow-Blatchford vs Rockall explains which score answers which question, and the Rockall score calculator covers both versions.
• Ask the follow-up. "Which patients with a low Glasgow-Blatchford score still need admission?" gets a cited answer from the ACG guideline and the international consensus.

Can AI help stage liver fibrosis in MASLD?

AI can help stage liver fibrosis in MASLD by laying out the noninvasive pathway step by step with its sources, while a calculator gives the number. MASLD, metabolic dysfunction-associated steatotic liver disease, is the name a 2023 multisociety Delphi consensus of 236 panelists from 56 countries chose to replace NAFLD; it requires hepatic steatosis plus at least one of five cardiometabolic risk factors. The 2023 AASLD practice guidance uses FIB-4, calculated from age, AST, ALT and platelet count, as the first step: under 1.3 is low risk, and patients stay in primary care. A FIB-4 of 1.3 or more leads to a second test, vibration-controlled transient elastography or the ELF blood test, and AASLD advises considering direct hepatology referral when FIB-4 is over 2.67. For people aged 65 and over, a cut-off of 2.0 replaces 1.3. The 2024 EASL–EASD–EASO guideline covers the same disease for Europe.

• Sources. The 2023 AASLD practice guidance, the 2023 nomenclature consensus, the 2024 EASL–EASD–EASO guideline and the original FIB-4 paper from 2006.
• Cirrhosis. The MELD calculator gives MELD, MELD-Na and MELD 3.0, which replaced MELD-Na for US transplant listing in July 2023; MELD for liver transplant covers referral.
• Alcohol-associated hepatitis. The Maddrey discriminant function calculator flags 32 or more, the threshold for severe disease in EASL and AASLD guidance; Maddrey vs MELD compares the two.
• Hepatitis B. WHO published updated hepatitis B guidelines in March 2024, and who.int is on AskMed's list of guideline sources.

Can AI help with acute pancreatitis, IBD and H. pylori?

AI can help with acute pancreatitis, inflammatory bowel disease and H. pylori by summarizing what each current guideline recommends and linking the paper, so you can check the wording yourself. In acute pancreatitis, the ACG guideline published in the American Journal of Gastroenterology in 2024 notes that almost one-fifth of patients develop complications such as pancreatic necrosis or organ failure. The BISAP score from Wu and colleagues in 2008 gives one point each for five findings in the first 24 hours, and the 2012 revised Atlanta classification grades the final course as mild, moderately severe or severe, where severe means organ failure lasting more than 48 hours. In Crohn's disease, the 2025 AGA living guideline in Gastroenterology made 16 recommendations and, for moderate-to-severe disease, suggests starting advanced therapy rather than stepping through corticosteroids and immunomodulators first. In H. pylori, the 2024 ACG guideline prefers bismuth quadruple therapy when antibiotic susceptibility is unknown and calls for a test of cure after treatment.

• Pancreatitis severity. The BISAP score calculator shows in-hospital mortality by score from the 2008 study; BISAP vs Ranson compares the two. The revised Atlanta classification and the ACG guideline are the papers to open.
• IBD. Ask how the AGA Crohn's guideline ranks advanced therapies, or what the 2025 ACG guidelines on ulcerative colitis and Crohn's disease recommend. AskMed names drugs and classes, never doses.
• H. pylori. Ask who to test and which regimen fits after a failed first course; the ACG guideline and the Maastricht VI/Florence consensus are the sources to check.

What should GI fellows, nurses, pharmacists and students look for in an AI?

GI fellows, endoscopy and liver nurses, pharmacists and students need an AI tool whose gut and liver answers can be checked in seconds and that names the guideline it quotes. First, citations: each claim should link to the guideline, trial or drug label behind it, not to a reading list at the end. Second, the society and year: ACG, AGA, AASLD, EASL and NICE guidance can differ, and the AGA publishes living guidelines that are updated as evidence arrives, so an answer should say whose guidance it quotes and from when. Third, doses: AskMed explains what a drug class is for, how it works, what to monitor and its side effects, but never gives doses, which come from the label. Fourth, access: OpenEvidence's App Store listing says an NPI is required and its Terms exclude the UK, EU and EEA, while UpToDate Expert AI needs an UpToDate subscription. AskMed needs no NPI or license and works in any country, on iPhone, iPad, Android and the web.

• Fellows and residents. Research Mode for journal club, and "what changed in the latest IBD guideline?" questions on rounds.
• Endoscopy and liver nurses. Monitoring after endoscopy, warning signs of a rebleed and signs of hepatic encephalopathy, with sources.
• Pharmacists. Interactions between named drugs, drug-induced liver injury and which drugs need caution in cirrhosis, without doses.
• Students. Paste an exam-style question with its options: the first sentence names the correct option and the answer explains why each other option is wrong.

What are the limits of AI for gastroenterology?

The main limit of AI for gastroenterology is that an answer can only be as good as its sources and the question it was given, and GI and liver guidance changes often, with living guidelines and new disease names such as MASLD. AskMed searches a fixed list of medical sites, so a society guideline published elsewhere may reach AskMed only as a PubMed abstract, and every AskMed answer is written by an AI language model that can misread a source or leave something out; no person reviews it before you see it. Open the citation behind any sentence you act on and check that it covers the same patients, since evidence in compensated cirrhosis does not answer a question about acute-on-chronic liver failure. AskMed reads text, not endoscopy photos, CT scans or histology slides, and it gives no doses: take those from the current label or your local formulary. AskMed is for education and reference by healthcare professionals and students, not for emergencies or patients' self-diagnosis.

• Paste the report, not the picture. An endoscopy, imaging or pathology report as text or a PDF gives AskMed words it can use; attachments explains what is read.
• Check the source. Every AskMed claim has its own link, so you check one sentence against one page.
• Report what looks wrong. Tap the thumbs down under an AskMed answer and pick a reason, such as Inaccurate or Sources don't match.
