For in-house legal teams

Your legal department,
with a memory.

Subsumio gives in-house counsel what they've never had: every contract, compliance document and legal opinion indexed, answerable and audit-ready — cited answers in seconds, not days of document hunting.

The in-house reality

Contract chaos

Hundreds of contracts across business units, each with different renewal dates, liability caps and termination clauses. Finding the one that matters takes days.

Compliance pressure

AI Act, GDPR, sector-specific regulations — the compliance landscape shifts faster than any team can track manually.

External counsel costs

Every external legal question costs thousands. Your team needs to answer the routine ones internally before they become external bills.

Built for legal operations

Contract intelligence

Bulk-analyze contracts: surface renewal dates, liability caps, termination clauses and anomalies across the entire portfolio.

Compliance tracking

Map regulatory requirements to internal policies. Track gaps, flag deadlines, maintain an audit trail for supervisors and regulators.

Institutional memory

Every legal opinion, memo and external counsel answer indexed and queryable. New team members get up to speed in minutes.

Answer before you ask external

Ask Subsumio first — if the answer is in your documents, you save the external counsel fee. If not, you know exactly what's missing.

Matter-level isolation

Scoped access per business unit and per user — HR legal, M&A legal, IP legal each see only what they should.

Audit-ready by design

Every query and answer is logged with sources. When the auditor asks 'how did you reach this conclusion?', the trail is there.

From reactive to proactive legal ops

The retrieval core benchmarks at 99.8% Recall@8 on LongMemEval (500 questions) — meaning when you ask 'which contracts have auto-renewal in Q3?', you get the complete answer, not a partial guess.

Questions, answered

Subsumio imports from shared drives, SharePoint, and via API. Document metadata (author, date, matter) is preserved during indexing.

Yes. Access is scoped per matter and per user. HR legal can't see M&A legal's files, and vice versa — fuzz-tested, zero leaks.

Subsumio provides source citations on every answer, gap analysis for transparency, and full audit logs. This aligns with AI Act transparency requirements for internal tools.
