Subsumio is the case management software for law firms: centrally manage files & documents, automate deadlines per ZPO/BGB/ABGB, and get AI legal analysis with page-level citations — GDPR-compliant and EU-hosted. ChatGPT, Codex & Claude can't read your case files. Subsumio can.

The decisive detail is on page 347 of a brief someone else read eight months ago.
Client files in a US-hosted AI tool? Your professional duty of confidentiality says no — and so do your clients.

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.
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.
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.
German electronic legal mail (beA XML export) lands straight in the case file: sender, case reference and attachments captured and searchable — no copy-paste.
Screens every new client or opposing party server-side against the entire case base and flags conflicts of interest before the mandate is accepted.
Book minutes by lawyer/activity, capture billable expenses, create invoices from open work, mark billed entries and export a DATEV-ready accounting file.
Subsumio is built for professions where confidentiality is law, not preference.
