Gaptrium™ processes your entire document corpus locally — in your browser, without uploading a single file — and reveals what the literature is ignoring.
Try free — no signup required →Zero capture on every plan. Documents are processed entirely in your browser. No file ever reaches our servers. Compatible with classified, legally privileged, and trade secret material.
Heat Map Analysis
Visualise which topics are densely covered and which are systematically ignored across your entire document corpus.
Explore Heat Map →Gap Analysis
Identify terms present in your corpus but systematically under-covered — the research gaps no AI can reliably find without hallucinating.
Explore Gap Analysis →Bridge Map
Reveal which concepts co-occur across your corpus — mapping the bridges between ideas and the structural gaps where connections are missing.
Explore Bridge Map →PICO Analysis
Structure your corpus around the PICO framework — Population, Intervention, Comparator, Outcome. Assign terms to domains and map documents against each dimension for reproducible systematic review methodology.
Explore PICO Analysis →Evidence Gap Map
Cross-tabulate two PICO domains to reveal where evidence exists and where it is absent. Green cells show covered combinations — empty cells are evidence gaps, ready to monitor via Pulse Research.
Explore Evidence Gap Map →Timeline Analysis
Track how research topics evolve over time — revealing emerging paradigms, declining fields, and the trajectory of your own research area.
Explore Timeline →Pulse Research
Monitor live term frequencies across global research and news feeds — know what the academic world is discussing now, before it becomes literature.
Explore Pulse Research →Search Assistant
Build boolean search strings with MeSH and DeCS controlled vocabulary lookup, launch them into 25+ academic databases, and log every search in a PRISMA 2020-compliant checklist — all without leaving Gaptrium™.
Explore Search Assistant →Patent Explorer
Cross-reference your research corpus against 8 patent databases — find what is heavily researched but not yet patented, before competitors do.
Explore Patent Explorer →Author Intelligence
Identify the key researchers driving each topic in your corpus — without bibliometric databases, from your own documents alone.
