3 contradictions found: 1. Delivery date — Statement of claim says March 12; witness K. states "end of April" (protocol p. 14). 2. Payment terms — Brief of Jan 9 claims 30 days net; the contract exhibit shows 14 days. 3. Prior notice — Defense asserts no warning was given; email exhibit B7 documents one. ⚠️ Gap: exhibit B7's authenticity hasn't been addressed by either side yet.

The winning USP

Subsumio Copilot — right inside WhatsApp

Book time, file documents, query matters — from your phone, no app switch, no training. The copilot understands the matter and files everything for confirmation in the brain.

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.

Sound familiar?

Case knowledge buried in PDFs

The decisive detail is on page 347 of a brief someone else read eight months ago.

US clouds are a non-starter

Client files in a US-hosted AI tool? Your professional duty of confidentiality says no — and so do your clients.

Knowledge walks out with people

When a senior associate leaves, years of matter context leave too — unless the firm's knowledge lives somewhere durable and answerable.

Capabilities

Built for confidentiality-first work

From deadline control to contradiction detection — all on your infrastructure, every answer cited.

Deadline control (ZPO & BGB)

Computes statutory and appeal deadlines with correct month arithmetic (§ 188 BGB) and weekend roll-forward (§ 222 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 for self-hosting, Vercel Blob/S3-style cloud storage 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)

Screens every new client or opposing party server-side against the entire case base and flags conflicts of interest before the mandate is accepted.

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 accounting file.

“

Engine-grade retrieval, not a chat wrapper

The retrieval core benchmarks at 97.9% Recall@5 with hybrid search and a knowledge graph — and because it runs on infrastructure you control, your IT governs every system that touches client data.
