AI Research Gap Finder & Literature Search
Don't know where to start? Switching fields? Going for Associate or Full Professor? Use the guided finder to walk from department to discipline to a publishable gap. Or paste your topic directly. Every search also runs a literature search — the most relevant papers in our library plus the most-cited and most-recent work — which you can filter and sort like Web of Science. Create a free account to run a search — 25 credits to start, each search costs 15 credits. Powered by 250M+ works from OpenAlex and 120,000+ open gaps mined from 100,000+ papers in our 4.5M-paper local library.
A research gap finder is a tool that surfaces open, unanswered questions in a field — unexplored populations, untested methods, contradictions between studies — so you can pick a defensible, novel research direction. This one draws on 120,000+ open gaps mined from the abstracts, limitations, future-work and other gap-stating passages of 100,000+ papers in our local library, and returns those gaps together with the key literature behind each — the most-cited and most-recent work on the topic — plus a field snapshot queried live from 250M+ OpenAlex works. Drafting a proposal from a gap is a separate step costing 10 credits.

What This Tool Does
Field Overview
Real-time field analysis from OpenAlex showing total works, top venues, the year range covered, and the peak activity year.
Candidate Research Gaps
Open questions surrounding your topic, each labelled with where it came from — synthesised across papers, a single library paper, or mined externally.
Key Literature
Foundational classics (the most-cited work on your topic) and the newest papers you should read and cite.
Recent Research
The newest papers on the same topic, newest first, so your work stays current and avoids duplication.
Found your gap? Next steps: match your paper to the right journal with the Journal Finder, get AI peer review — editor-ready feedback before you submit, or run the Pre-submission Check for a quick triage.

Research gap finder — frequently asked questions
What is a research gap finder?
A research gap finder surfaces open, unanswered questions in a field so you can pick a defensible, novel direction. Ours draws on 120,000+ open gaps mined from 100,000+ papers in our local library and queries 250M+ works from OpenAlex for the field overview, returning candidate gaps, that overview, and the key literature behind each.
Is there a free research gap finder?
Yes — browsing our 1,100+ pre-analysed research gaps by field is free with no account, and a free account includes 25 welcome credits, which covers one full AI gap search (15 credits). Searches after that use one-time credit packs; credits never expire.
How do I find a research gap in my field?
Enter a topic or paste your abstract. The finder returns a real-time OpenAlex field snapshot (total works, top venues, year range and peak year), candidate research gaps with the provenance of each, and the foundational + recent papers to read and cite. Full-sentence queries retrieve more specific gaps than keywords.
What does the research gap finder cost?
Creating an account is free and comes with 25 credits to start. Each research-gap search costs 15 credits. Retrieval runs locally over our library plus the OpenAlex open API, so it stays fast; credits are bought in one-time packs and never expire.
How does the AI identify research gaps?
It combines real bibliometric evidence (OpenAlex coverage, citation and recency signals) with gaps mined from the abstracts, limitations, future-work and other gap-stating passages of 100,000+ papers, and surfaces each with the source behind it — grounded in real literature, not invented.
Can it help me choose a publishable, novel topic?
Yes. Use the candidate gaps as starting points, confirm each by reading the 'future work' of the surfaced papers, then run a Pre-Check or full AI Review once you have a draft.
Can you suggest a research gap for a specific topic or compound?
Yes — enter the topic or paste an abstract and the finder returns evidence-backed open questions for exactly that subject, each with the key literature behind it. You can deep-link a topic directly as /research-gaps?topic=<your topic>. A free account starts with 25 welcome credits, and one full search costs 15.
Does the research gap finder use OpenAlex?
Yes. Every search runs a real-time query against 250M+ works in the OpenAlex API for field coverage, top venues, and citation/recency signals, combined with 120,000+ open gaps mined from 100,000+ papers in our own library.
