Your literature review
should tell you
what no one has studied yet.

Gaptrium™ processes your entire document corpus — papers, theses, reports, patents — and maps what is covered versus what is systematically absent. Not a summariser. A gap detector. Every finding is reproducible, citable, and defensible under peer review.

"The methodology was validated across three institutional contexts and published in Springer Nature Systematic Reviews — providing the scientific foundation for every analysis Gaptrium™ produces."

Who uses Gaptrium™ for research

From first-year Master's
to published systematic review.

Whether you are defining your research question, writing your literature review chapter, or producing a systematic review for publication — Gaptrium™ accelerates the part that takes the most time: finding what has not been studied.

📚
Systematic Literature Review
Load your full corpus, define your terms, and get a Heat Map showing which concepts appear in which documents — and which are absent across the entire set. Methodology compliant with PRISMA and reproducible by any reviewer.
🎓
Doctoral & Master's Thesis
Define your research gap with evidence, not intuition. The Gap Analysis view shows which concepts are present in 80% of your literature but addressed in zero papers — your contribution space, visualised.
🗺️
Field Mapping & State of the Art
Upload papers from the last five years, run Clusters and Timeline analysis, and produce a visual map of how a research field has evolved — and where it is heading next.

How it works

Load. Analyse.
Discover what's missing.

1
Load your documents
Drop PDFs, TXT files, BibTeX exports, or RSS feeds directly into the platform. No upload — everything is processed locally in your browser. Your documents never leave your device.
2
Define your terms
Enter the concepts, keywords, or research constructs you want to track. Up to 200 terms on the Scope plan. You control the vocabulary — Gaptrium™ does not guess or infer.
3
Read the Gap Analysis
The Gap Analysis view classifies each term: how present is it in your corpus? Which terms appear in most papers but are never the primary subject? Those are your gaps — the unexplored territory in your field.
4
Export for your thesis or paper
Export to CSV, HTML, PNG, or PDF. Every output includes the parameters you used — corpus size, terms, date of analysis — making your methodology fully reproducible and citable.

Why Gaptrium™ is not AI — and why that matters for research

Peer reviewers ask:
"How did you reach this conclusion?"

With AI tools, the honest answer is: "I don't know exactly." Probabilistic models produce plausible-sounding summaries that change every run. They cannot be cited with a method. Gaptrium™ is different by design.

AI summarisers — problems for research
Output changes each run — not reproducible
Fabricates citations and statistics (hallucinations)
Cannot identify systematic absences — only summarises what is present
Methodology not citable or defensible under review
Documents processed on remote servers — confidentiality risk
Gaptrium™ — deterministic analysis
Same corpus + same terms = same result, always
Zero hallucinations — mathematical frequency analysis only
Identifies what is absent — the research gap — not just what is present
Validated methodology — peer-reviewed in Springer Nature 2026
100% local processing — your documents never leave your device
