What is a research gap?

A research gap is an area within a field of study that has not been sufficiently explored or where existing research is incomplete, outdated, or contradictory. Identifying research gaps is crucial for PhD students, masters scholars, and independent researchers because it forms the foundation of an original research contribution.

Research gaps can exist in many forms — geographic gaps (a topic studied globally but not in India), methodological gaps (a phenomenon studied qualitatively but never quantitatively), population gaps (studied in urban areas but not rural), or temporal gaps (studied decades ago but not with current data).

Our research gap finder uses AI to analyse your proposed topic against 250M+ academic papers from OpenAlex, CORE, Semantic Scholar, and 6L+ Indian theses from Shodhganga — then identifies exactly which gaps exist and how severe they are.

How this research gap finder works

1

Enter your topic

Type your research area, thesis title, or broad domain. Can be specific ("microplastics in Maharashtra groundwater") or broad ("AI in Indian agriculture").

2

AI searches 250M+ papers

Our AI queries multiple academic databases simultaneously — including Indian theses from Shodhganga that no other tool indexes.

Faculty & supervisors

Verify student topics haven't been done before approving proposals

Research scholars in India

Check gaps specific to the Indian academic landscape — not just globally

Frequently asked questions

Is this research gap finder really free?

Yes. You can use it without creating an account. Anonymous users get 2 analyses per month. Sign up for free to get 5 per month, or upgrade to Pro (₹199/month) for unlimited.

What databases does it search?

We search across 250M+ papers from OpenAlex, CORE, Semantic Scholar, PubMed, and other open-access repositories. For Indian theses, we index 6L+ works from Shodhganga — the only tool that does this.

How is this different from a manual literature review?

A manual literature review takes weeks and still misses papers. Our AI checks your topic against millions of works in seconds and identifies gaps you might never find manually — especially geographic, methodological, and temporal gaps.

Can I use this for my PhD proposal?

Absolutely. Many researchers use our gap finder to strengthen the 'research gap' section of their PhD proposals. The output directly shows what hasn't been studied and why your research would be original.

Does it work for topics outside India?

Yes. While we have the strongest coverage of Indian theses, our global corpus covers 250M+ papers from every country. The gap analysis works for any research topic in any geography.

How accurate is the gap analysis?

Our AI uses real data from academic databases — it doesn't make up numbers. The 'Indian theses' and 'global papers' counts come from actual search results. However, no tool can guarantee 100% coverage of all academic work ever published.
