The architectural limit problem

AI tools hit a wall.
Gaptrium™ doesn't.

Every AI platform imposes hard limits on file size and document count per session — typically 5 to 20 files, 10 to 25 MB each. This is not a pricing decision. It is an architectural constraint that cannot be removed no matter how much you pay.

Gaptrium™ processes documents locally in your browser. There is no server receiving your files — so there is no server imposing limits. The only ceiling is your device's processing power.

✗ AI platforms — hard limits

Who uses it

One technology.
High-stakes decisions across every sector.

Any domain that produces documents has gaps in those documents. Gaptrium™ finds them — deterministically, reproducibly, and without sending your data anywhere.

🔬
Systematic Literature Review & R&D
Identify what the literature systematically ignores before writing your thesis, grant application, or publishing. Find the gap no one is covering — with evidence any peer reviewer can reproduce.
🏛️
Media Monitoring & Narrative Intelligence
Track which topics are gaining traction across thousands of articles — and identify what mainstream coverage is systematically ignoring. Turn media silence into strategic intelligence, weeks before it becomes a headline.
💼
Competitive Due Diligence & Market Intelligence
Cross-reference competitor filings, earnings reports, and industry research. Find what rivals are deliberately not mentioning — the omissions in their annual reports that reveal emerging risks and unexploited niches.
🏭
Regulatory Compliance & Safety Audit
Audit hundreds of technical manuals, compliance reports, and safety filings to guarantee no norm was omitted. Every finding is mathematically traceable — defensible against any regulator, court, or inspector.
🔍
Legal Discovery & Contract Audit
Process thousands of pages of contracts, filings, or disclosed documents to surface inconsistencies, omissions, and concealed facts. Every finding traces back to the exact clause in the exact document.
🏛️
Government & Intelligence Analysis
Analyse classified documents, policy briefs, and intelligence reports entirely within the browser — no file ever leaves the device. Compliant with the most stringent data sovereignty requirements by architecture.

The platform · See it in action

Nine analytical lenses.
One deterministic engine.

Every tool runs on the same engine — same corpus, same parameters, same result. Always.

Coverage Engineering

What is there

Gaptrium™ analyses massive volumes of files and cross-references the information to find the pattern of coverage. It shows how themes, data, and arguments interconnect systematically — revealing hidden connections that would escape human reading.

Gap Intelligence

What isn't there

Gaptrium™ isolates what the documentation omitted. The software scans the data corpus and pinpoints blind spots, intentional silences in reports, and information voids that require investigation.

Not a competitor to AI.
A solution to a problem AI cannot solve.

AI is an extraordinary tool for many tasks. But when the problem requires deterministic results, reproducible findings, and zero data exposure — AI is structurally incapable of delivering. Not because of limitations that can be fixed with a better model or a higher-tier plan. Because probabilistic inference and deterministic analysis are fundamentally different things.

Gaptrium™ fills the gap AI leaves behind — the problems that require a finding to be reproducible by any reviewer, traceable to the source, and produced without your documents ever leaving your device.

Import hundreds of PDFs, reports, BibTeX, or RSS feeds. No size limit. No upload. The files never leave your device.
02

The Gaptrium™ engine runs entirely inside your browser. Your confidential data never touches our infrastructure — by architecture, not policy.
03
Explore patterns & gaps
Export mathematical reports ready to support high-stakes decisions. Every finding is reproducible by any reviewer with the same documents.

Why AI cannot solve this problem —
regardless of model, plan, or provider.

These are not weaknesses that will be fixed in the next version. They are properties of how probabilistic models work — and why a different class of tool is needed for deterministic analysis.

Capability ✗ Why AI cannot do this ✔ What Gaptrium™ makes possible
Document volume & file size 5–20 files per session · 10–25 MB per file · loses context across documents · architectural constraint — cannot be fixed regardless of plan No file size limit · Trial: 20 docs · Scope: 100 · Signal: 500 · Core: unlimited · bounded only by your device's processing power
Hallucinations & reliability Invents facts, citations, clauses, and statistics that do not exist in the source documents. No way to detect or prevent — it is a property of probabilistic models Zero hallucination — every output is a direct count from a specific document. Nothing is inferred, generated, or invented
Reproducibility Probabilistic output changes on every run. Same question, different answer. No reviewer can reproduce or verify the finding Byte-identical results every time. Same corpus + same parameters = same result — tomorrow, next year, or in peer review. Methodology published Springer Nature 2026
Gap detection Can summarise what is present but cannot map what is missing or systematically omitted Specialised in auditing and isolating what was not written — the absence is the finding
Data privacy & compliance Documents uploaded to cloud servers. Data retained for model training. Compliance requires contractual guarantees that vary by provider and jurisdiction Zero upload — documents never leave your device. GDPR, UK GDPR & Swiss nFADP compliant by architecture. Safe for classified, legally privileged, and trade secret material
Pattern mapping Loses global context in long readings. Cannot process the full corpus as a unified structure Processes hundreds of files simultaneously as a single integrated corpus — full context, no memory loss
Auditability Black box — opaque scoring, no traceability. Unusable for court submissions, regulatory filings, or audit sign-off Every score traces back to a specific count in a specific document. Defensible in court, regulatory review, and peer-reviewed publication

AI figures based on publicly documented limits as of 2026. Gaptrium™ is not positioned as a replacement for AI — it addresses a class of analytical problems that probabilistic models are structurally unable to solve.

Peer-reviewed methodology

Not proprietary opinion.
Validated science.

Gaptrium™ is inspired by the MTTR methodology — published by the Intelligent Systems Research Centre, London Metropolitan University, in partnership with CTI Renato Archer (Brazilian Federal Government) — and independently validated across four institutional contexts: ITNG / Springer (2020), IEEE Transactions on Services Computing, ECKM · Coventry UK (2021), and Springer Nature Systematic Reviews (2026). Gaptrium™ shares no code, screen or implementation with MTTR.
