How it works — from document to a cited answer

Four steps. No tagging, no data entry — the brain wires itself.

1

Feed it

Matters, emails, PDFs, voice notes, WhatsApp — by folder, upload or copilot. OCR pulls text from scans too.

Upload · OCR · copilot
2

It understands

On every write the engine extracts typed edges — people, deadlines, relationships — as a legal knowledge graph.

Entities · graph · embeddings
3

Ask

Ask in plain language. Hybrid retrieval across vector, keyword and graph finds the decisive passages.

Hybrid search · reranking
4

Cited answer

A synthesized answer with page-level citations — plus an honest note on what the file is still missing.

Citations · gap analysis

Dashboard-native

Features run as a legal workflow.

Matter, copilot, deadline, source and approval work together. That is why Subsumio describes every capability in the dashboard context lawyers actually use.

The office in your pocket

Always with you — never miss a deadline

Subsumio is your secretary on the go: book time, file receipts, track deadlines — all via WhatsApp, no app switch.

  • Time & expenses in seconds

    "Time 0.5h matter Müller, call" → captured, linked to the matter, one tap to confirm.

  • Receipt photo → right matter

    A document or photo with the case reference in the caption lands in the vault, audit-ready.

  • Voice note on the go

    Dictate after the hearing — transcribed and attached to the matter before you're back at the office.

  • Deadlines that don't forget you

    Daily digest, holiday roll-forward, statutory deadlines calculated automatically. You sleep — Subsumio watches.

Subsumio Copilot

All capabilities

Everything a firm needs — in one brain

Self-hosted or EU cloud. Every answer cited. Every feature on your own infrastructure.

Deadline control (ZPO / BGB / ABGB / ZGB)

Computes statutory and appeal deadlines with correct month arithmetic (§ 188 BGB / § 80 ABGB) and weekend roll-forward (§ 222 ZPO / § 84 ZPO) — with the governing statute cited. A daily email digest flags overdue and critical deadlines.

WhatsApp matter copilot

Lawyers can send time entries, notes, tasks, deadlines, expenses, questions, PDFs, photos and voice notes from their phone. Subsumio stores them in the brain and links media to the right matter when the caption contains the case reference.

Document vault with durable storage

Matter documents, WhatsApp media and uploaded evidence are kept in the vault with hash, source, size and storage metadata — local disk on Hetzner EU servers, or S3-compatible object storage (Cloudflare R2) for hosted plans.

beA integration

German electronic legal mail (beA XML export) lands straight in the case file: sender, case reference and attachments captured and searchable — no copy-paste.

Conflict check (§ 43a BRAO / § 10 RAO / BGFA)

Screens every new client or opposing party server-side against the entire case base and flags conflicts of interest before the mandate is accepted. Covers § 43a BRAO (DE), § 10 RAO (AT) and BGFA (CH).

Time, expenses, invoices & DATEV

Book minutes by lawyer/activity, capture billable expenses, create invoices from open work, mark billed entries and export a DATEV-ready (DE) or ADATEV-ready (AT) accounting file.

Case law DE · AT · CH

Live search across openlegaldata/BGH (DE), RIS-OGD (AT) and bger.ch (CH) — relevant judgements land in the brain, citable, in one click.

Your server, your jurisdiction

Self-host the full engine on firm hardware with local storage, or choose EU-hosted cloud with DPA and durable object storage. Client data never leaves your control.

Offline-first daily work

Cases, contacts, deadlines, invoices, vault, contracts and research keep local caches and queue changes until the cloud brain is reachable again.

Contradiction detection

The Dream Cycle surfaces conflicting statements across briefs, exhibits and protocols — with citations.

Every claim, sourced

Answers cite the exact pages they come from. Verify in one click before anything goes into a brief.

Matter-level isolation

Scoped access per matter and per user — fuzz-tested, zero leaks between cases or teams.

One answer instead of ten documents

Most tools stop at retrieval: here are your chunks, good luck. Subsumio reads them for you and writes the answer — and tells you what it couldn't find.

Synthesized prose answers

Cross-document synthesis over people, companies, deals and ideas — written out, not pasted together.

Citations on every claim

Each statement links to its source page. One click to verify before you rely on it.

Gap analysis

The answer ends with what the brain does NOT know yet — so silence never masquerades as certainty.

Hearing & meeting prep

Ask before a client call or hearing: last contact, open commitments, contradictions found, what changed since. Walk in briefed, not hunting.

subsumio — ask

$ what's still open in the Bauer matter?

→ 3 open items across 4 documents:

1. Reply brief to the court (drafted, not filed)

2. Expert report from Dr. Klein (requested, overdue)

3. Settlement range to confirm with the client

⚠ Gap: no note filed for Thursday's client call

Built for confidentiality-first work

Self-hosting, tested isolation, EU AI Act compliance, and an honest roadmap. The full security and data-protection story lives on its own page.

Five capability areas, one engine

Questions, answered

All data is encrypted at rest and in transit. Self-hosting is available. No data is shared with third parties or used for model training.
