AI-Powered Research Evaluation

Is Your Research Idea
Actually Worth Pursuing?

Input your idea below to see if it has been done before, if it can be done, and how likely it is to fill a proper gap in the evidence. ResearchChecker-AI searches through MEDLINE/PubMed, Embase, Cochrane CENTRAL, Web of Science, Scopus, ClinicalTrials.gov, and PROSPERO to give you a full-fledged, customized report, saving researchers weeks of repetitive work.

Stop Wasting Months on Research Ideas That Have Already Been Done.

ResearchChecker is the first tool purpose-built to evaluate whether a medical or biomedical research question is novel, feasible, and worth pursuing — in seconds, not weeks.

The Problem We Solve
Every year, thousands of researchers spend weeks or months developing a protocol, searching literature, and writing proposals — only to discover that an identical systematic review was published last month or a PROSPERO registration already exists. This is a massive, silent waste of academic resources.
How We Change the Game
What used to take a researcher 2-3 weeks of manual literature searching, database screening, and PROSPERO checking now takes 15 seconds. ResearchChecker doesn't just search — it evaluates, cross-references, identifies gaps, and tells you exactly where the opportunities are.
Real Databases, Real Evidence
Every evaluation queries PubMed, ClinicalTrials.gov, PROSPERO, Europe PMC, and the Cochrane Library in real-time. The "Similar Literature" section shows actual papers with clickable DOI links, not AI-generated references. The evidence counts are real numbers from live database queries.
Private and Secure
Your research ideas are never stored, logged, or shared with any third party. All queries are processed in real-time and immediately discarded. We have no accounts, no databases, and no way to recover your search history — by design.

Who Is This For?

Medical students exploring thesis topics who need to know if their idea has already been studied to death. Residents planning their first systematic review under time pressure. Faculty members assessing whether a proposed study fills a genuine gap before committing lab resources. Research coordinators screening incoming proposals for institutional review.

If you've ever spent weeks developing a protocol only to discover that three identical reviews were published last year — or worse, found a PROSPERO registration for the exact same study two weeks before your planned submission — ResearchChecker exists to prevent that from ever happening again.

What Makes This Different From Just Searching PubMed?

PubMed tells you what exists. ResearchChecker tells you what it means. It identifies population gaps (studied in adults but not pediatrics), methodological gaps (only retrospective data, no RCTs), temporal gaps (last major study is 5+ years old), and comparator gaps (head-to-head comparisons missing). It scans for active PROSPERO registrations that signal upcoming competition. It identifies the dominant research groups in the space so you know who you're competing against. And it suggests specific, concrete pivots that would make your idea more publishable.

How It Works

Real Databases. Structured Analysis. Transparent Methodology.

ResearchChecker combines live database queries across five major biomedical databases with advanced AI reasoning to produce evaluations grounded in real evidence.

Step-by-Step Process

1. Describe Your Research Idea
Enter your research question in plain language. The more specific you are — population, intervention, comparator, outcome, study type — the more precise the evaluation.
2. Parallel Database Search (2-3 seconds)
Your query is simultaneously sent to PubMed, ClinicalTrials.gov, and Europe PMC. All searches run in parallel. Key terms are automatically extracted for optimal matching.
3. AI-Powered Analysis (8-12 seconds)
Real database results — paper counts, article titles, trial registrations, DOI links — are analyzed by an AI research methodologist. No hallucinated counts; all numbers come from live APIs.
4. Structured Intelligence Report
You receive a comprehensive report with letter grades, strategic verdict, evidence landscape, gap analysis, PROSPERO check, similar literature with DOIs, feasibility assessment, and publishability estimate.

What Each Result Section Means

Novelty Grade (A-F)
A = No existing work; wide-open gap. B = Sparse literature. C = Some studies, clear gap remains. D = Well-studied, minor angles only. F = Saturated; recent SR/MA published.
Evidence Landscape
Snapshot of current literature: existing RCTs, observational studies, systematic reviews, Cochrane reviews, ongoing trials, and preprints signaling upcoming saturation.
Gap Analysis
Identifies five gap types: Population, Methodological, Outcome, Temporal, and Comparator. The most actionable section — tells you exactly where opportunities exist.
Publishability Estimate
Estimates target journal tier (high-impact, specialty, open-access), recommends specific journals, and identifies the study design that would best fill the identified gap.
PROSPERO Registry Check
Searches for existing registered systematic review protocols. Shows actual registrations found with clickable links, so you can verify competition directly.
Similar Literature
Real papers from PubMed and Europe PMC with titles, authors, journals, years, and clickable DOI links. These are actual database results, not AI-generated citations.
FAQ

Frequently Asked Questions

Everything You Need to Know About Using ResearchChecker.

How accurate are the evaluations?
The database counts and DOI links are real — they come from live API queries to PubMed, ClinicalTrials.gov, and Europe PMC. The novelty assessment, gap analysis, and competitor scan represent AI-informed judgment based on these real data points. Use it as a powerful screening tool to guide your research planning, not as a replacement for a comprehensive literature review or expert mentorship.
Is my research idea stored or shared?
No. Your input is processed entirely in real-time. Nothing is logged, stored in any database, or shared with any third party. Once your browser tab is closed, your query is gone permanently. We have no user accounts and no way to recover previous searches.
Which databases does it search?
PubMed (via NCBI E-utilities API), ClinicalTrials.gov (API v2), and Europe PMC (which indexes Cochrane Library content, clinical guidelines, preprints from medRxiv/bioRxiv, and additional sources beyond PubMed). PROSPERO is checked via targeted search and direct links are provided.
Can I use this for non-medical research?
ResearchChecker is optimized for medical and biomedical research, particularly systematic reviews, meta-analyses, and clinical research. The database integrations are specific to biomedical literature. The AI can reason about other fields but the evidence grounding will be weaker outside biomedicine.
How should I phrase my research idea for the best results?
Be as specific as possible using PICO format: Population, Intervention, Comparator, Outcome, and Study Type. "Meta-analysis of PD-1 inhibitors versus chemotherapy for first-line treatment of microsatellite-stable colorectal cancer" will produce far better results than "cancer treatment research."
Is this free to use?
Yes. ResearchChecker is currently free to use with no account required.
