Other AI tools remember chat histories. Subsumio understands your cases: every night, the SuperBrain consolidates them into a living legal memory — like the human hippocampus during sleep. Five quality layers, contradiction probing, citations. Zero hallucinations.

LongMemEval, 500 questions
You ask a question. The model answers. Then it forgets everything. Other tools store chat histories and call it 'Memory'. Subsumio builds a knowledge graph — not chat storage, but understanding. Every prompt in other tools is isolated — no memory, no learning, no understanding. Hallucinations are fought at the prompt level: with hope. The model is judge and defendant at once.
You ask GPT-5 or Claude
Model generates — without memory
Everything is discarded. Next prompt = zero context.
Subsumio builds a knowledge graph from your documents every night. Facts are extracted, synthesized, probed for contradictions, and validated by an ensemble judge that surpasses human lawyers. The result is not a chat history. It's a long-term legal memory that gets sharper every night — not just bigger, but more understanding. The longer you use it, the better the SuperBrain understands your firm.
Documents, emails, matters, conversations
5 layers: Extraction → Synthesis → Verdict → Probe → Ensemble
Persistent knowledge graph with facts, takes & relationships
Every answer from the graph — with citations
Every night: 29 phases · 5 layers · 1 knowledge graph
Every take passes through five quality layers before entering your knowledge graph. Verified LEXam scores per model. This is the architectural moat no competitor can cross.
Specialized extraction models structure facts from conversations, documents and emails. No legal reasoning — just structuring. Every night, new facts are written to the brain.
DeepSeek V3.2 synthesizes facts into takes with legal reasoning. LEXam score 57.42 — better than GPT-4o (56.93), on par with GPT-4.1 (57.50). Open-weight, fully transparent.
A reasoning model evaluates every single take: accepted, rejected, or sent back for revision. Bad takes die before they reach the graph. LEXam score 56.53 — nearly identical to GPT-4.1.
Chunk pairs are nightly checked for logical contradictions. 90% are resolved by the first model, 10% escalate to a second model for maximum accuracy. Contradictions are flagged — not hidden.
An ensemble of two open-weight models evaluates final legal quality. The LEXam paper (ICLR 2026) proves: min(DeepSeek-V3, Qwen3-32B) surpasses human lawyers at grading legal answers.
5 layers. 29 phases. A knowledge graph that grows every night — and gets richer through reconsolidation.
While you sleep, the SuperBrain runs 29 phases — just like the human brain repeats, strengthens, and rewires memories during sleep. Facts become knowledge, takes become understanding, contradictions become clear signals. New: Engram Maturation and Reconsolidation — inspired by neuroscience. All automatic, all monitored, all logged.
Conversations, emails, documents → structured facts with source references
Facts → brain pages with legal reasoning and citations
Cluster facts → promote takes → remove duplicates
New memories start 'silent' and mature over 7 days via a sigmoid curve — like the human hippocampus. Implicit knowledge becomes explicit understanding.
When a memory is retrieved, it becomes 'labile' for 60 minutes — new nuances can merge in, like in the human brain. Knowledge gets richer, not just bigger.
Chunks → vector space for semantic search across all matters
Cross-take themes, connections and recurring risks
Logical conflicts between takes are flagged — not hidden
Legal quality scoring with LEXam-validated models
Track model quality over time · Detect drift · Adjust
Other legal AI uses multi-model routing per task. We use multi-model quality layers per take — with a knowledge graph that consolidates every night. That's not a feature difference. That's an architectural paradigm shift.

Forecast: +5–10 LEXam points over base Qwen3-32B (40 → ~45–50). Ensembled with DeepSeek V3.2: quality at GPT-4.1 level (57.50) — with a model that understands DACH law from the ground up.
From the first matter to complex multi-party cases — the SuperBrain works in every case. Here are the concrete use cases law firms use daily.
Questions about a case? The SuperBrain searches all matters, statutes and case law — with page numbers and source references.
Contracts are automatically analyzed, risks flagged, and amendment suggestions generated — with BGB/ABGB references.
Automatic deadline calculation per ZPO, BGB, ABGB. The SuperBrain monitors and alerts — before deadlines expire.
Every matter, every correspondence becomes a knowledge graph. Never solve the same problem twice.
Cross-reference audit finds conflicts of interest before they become a problem — across all clients.
Automatic summaries, status reports and cost estimates — straight from the knowledge graph.
The SuperBrain processes everything inside your isolated environment. No training on your data. No data to third parties. Confidentiality by architecture — not by promise.
Every case is logically separated. Client confidentiality stays confidential.
Models never learn from your documents. Architecturally guaranteed.
Hetzner Falkenstein (DE) or fully on-premise.
Every take, every verdict, every calibration is traceably logged.
The SuperBrain wasn't made GDPR-compliant after the fact. Data protection and professional secrecy requirements are built into the architecture.
