Legal OS was designed with one constraint: no feature ships until a practicing attorney would miss it if it were removed. The result is a platform with exceptional density and zero cruft.
Every case, client, document and deadline — organized in one structured workspace. Real-time updates across your entire practice.
Generate pleadings, contracts and correspondence from firm-approved templates. AI-assisted drafting that preserves your voice.
Legal OS learns your billing patterns. Entries are captured contextually and pushed to invoices with zero data re-entry.
A court-rules engine calculates every deadline chain from a single trigger date. Jurisdiction-aware and auto-recalculated.
Granular conflict-of-interest checks and automated access partitioning — enforced at the infrastructure level, not just the UI.
Revenue by practice group, realization rates, originations and utilization — dashboards built for managing partners.
Every answer is synthesized strictly from your firm's own documents and returned as a verified memo — with anchored citations to the exact page and paragraph. When there is no basis in the record, Legal OS says so. It does not invent.
A new matter opens with a structured intake form. Legal OS runs an instant conflict check across all existing clients and related parties.
A dedicated workspace is created: document vault, calendar, task list and billing ledger — linked from the first minute.
Time is captured as work happens. Documents version automatically. Deadlines cascade from court rules, not manual entry.
A closing checklist ensures every deliverable is executed. The matter archives to permanent, searchable storage with a full audit trail.
Legal OS replaced four separate tools we'd stitched together. The deadline engine alone has saved us from malpractice exposure on at least two occasions.
The billing capture is unlike anything I've used. We increased realization by 18 points in the first quarter — and the attorneys actually prefer it to manual entry.
When you're handling federal litigation across three offices, version control on documents isn't optional. Legal OS treats it as infrastructure, not a feature.
For solo practitioners and boutique practices.
