The Subsumio engine
Most AI tools answer one prompt. Subsumio builds a durable, permission-aware brain over your own work: files, messages, meetings, entities, decisions and open loops.
Answers come from your matters, clients, deals and documents, not generic web guesses.
People, companies, files, deadlines and promises stay connected as reusable context.
Every synthesis keeps source trails visible, with gaps called out instead of hidden.
Self-hosted on your keys and hardware, or managed EU cloud when you want speed.
Bring files in via upload, Google Drive or your practice software — then ask in chat, with page-level sources.
From deadline control to contradiction detection — every answer cited, every deadline tracked.
Every AI answer cites the exact pages it comes from. Verify in one click before anything goes into a brief — no hallucinated references.
Statutory and appeal deadlines computed per ZPO/BGB/ABGB with correct month arithmetic and weekend roll-forward. A daily email digest flags what's critical.
Book time, file documents, send voice notes from your phone. Everything lands in the right matter — confirmation-gated, nothing reaches the file unseen.
Matters, emails, PDFs, voice notes, WhatsApp. Subsumio chunks, embeds and indexes automatically. OCR pulls text from scans too.
On every write, typed edges — people, deadlines, relationships — are extracted as a legal knowledge graph. No extra LLM calls.
Plain-language questions. Hybrid retrieval across vector, keyword and graph finds the decisive passages.
A synthesized answer with page-level citations — plus an honest note on what the file is still missing.
Illustrative scenarios based on what the engine does in production.
A paralegal
Uploads the incoming post and a scanned contract, then asks: “Which deadlines does this trigger?” — every statutory date is calculated, calendared and linked to the matter.
A lawyer
Sends a voice note and a PDF by WhatsApp with a matter reference, books 20 minutes, then asks: “Where do the opposing party's statements contradict each other?” — the file, time and answer are in one brain.
A managing partner
Indexes five years of matters and pleadings. A new associate asks: “Have we argued something like this before?” — and finds the 2023 brief in seconds.
Subsumio is built for professions where confidentiality is law, not preference.
Your hardware or EU hosting with a DPA. Client data never leaves the EU.
Your knowledge never trains shared models. Ever.
Page-level citations — verify in one click before anything goes into a brief.
Architecture for confidentiality holders — no third party processes client data.
Per seat, billed annually. Your firm's brain on infrastructure you control — EU-hosted or on-premise.
Pro
For the lawyer who lives on their knowledge. Annual billing saves 20%.
Annual billing −20 %. Included AI query and storage quotas shown per plan. Overages billed at transparent per-unit rates at month end — no surprise bills, no silent throttling.
Those return documents or chunks. Subsumio returns a synthesized answer with citations, walks a typed knowledge graph for relationship questions (“who invested in X?”), and tells you what it doesn't know — the gap analysis is the part that changes how you work.
Your choice. Self-host the engine on your own hardware, or use our managed EU cloud. Enterprise plans support on-prem and a signed DPA.
No. Sign up and your brain runs — fully managed, no keys, no infrastructure. Enterprise self-hosting runs on your own hardware with your own keys.
You see usage live in the dashboard and we ask before anything changes. No surprise bills, no silent throttling.
Never. Your knowledge is yours alone — never used to train shared models. Self-hosted, nothing leaves your building; on our EU cloud it stays encrypted and isolated per customer.
Three minutes to first answer on hosted plans. No credit card.
