Verifiable answers
Every answer traceable to its legal source and authority.
Who we are
LEGAION was built on one conviction: AI truly supports a lawyer only when every answer can be traced back to an authoritative source.
We combine AI with the requirements of the legal profession, delivering tools that back up the daily work of law firms and in-house teams.

From upload through verification and risk analysis to final editing inside Word — all in one auditable environment.
Concrete modules for every legal team - Verifier Engine, Predict, Witness Prep, Iron Audit, Flow - with a full citation and audit trail.
From the inbound envelope through CRM, calendar, tasks and billing, all the way to invoice delivery via KSeF — all in one auditable environment.
Letter, email, scan — automatically filed to the matter.
Every new letter, email and attachment lands in a single matter envelope. OCR, classification and client assignment happen automatically — zero manual sorting.
Client card, conflict checks, full history.
Contacts, conflicts of interest, ultimate beneficial owners and engagement history. Every envelope is instantly linked to the right client card and matter.
Procedural deadlines under team-wide control.
Procedural dates, limitation periods and contractual deadlines drop into the team calendar. The system guards every deadline and sends advance reminders.
Who does what, by when — spelled out.
Envelopes and deadlines turn into concrete tasks — partner, associate, paralegal. Everyone sees what to do today, tomorrow and this week.
Hours and fixed fees turned into invoices.
Time entries snap to tasks and matters. Hourly rates, success fees and fixed fees — all converted into an invoice with a single click.
Validation and delivery to Poland's e-Invoice system in one click.
The invoice passes validation, receives a KSeF number and is delivered straight to the National e-Invoice System. Full audit trail and live status in one view.
Verifier, Deep X-Ray and Drafter - inside Microsoft Word. No copy-paste, no context switching, no leaving the document you are working on. The add-in runs in Word desktop, Word for the web and Word for Mac.

Why the Word plugin
Verifier, X-Ray, Sentinel and Counter run directly inside Microsoft Word — no document migration, no new platform to learn. Open a file and LEGAION shows up in the side panel.
Every citation, clause and risk is checked against ISAP, EUR-Lex and SAOS — with a link to the source and a timestamp. Tracked changes are generated automatically, ready to accept.
Document content never trains our models. A dedicated Office session (1h idle TTL), AES-256-GCM E2EE and EU hosting — eIDAS, GDPR and EU AI Act compliance out of the box.
Verticals
LEGAION vertical for sports: clubs, agents, federations. FIFA RSTP & UEFA FSR compliance, transfer contracts and War Room.
