Your server. Your files. Your desk.
Lotus Legal is a document assistant built for firms that cannot use public AI — client confidentiality, bar ethics, and insurer requirements block sending matter content to vendor-hosted models. Inference runs on your office server. Your matters stay under your roof.
Harvey, Legora, and every other vendor-hosted legal AI tool process your matter documents on their servers. For most firms, that is not a policy question — it is a hard no. Client confidentiality, bar ethics rules, and professional liability insurers all draw the same line.
Lotus starts from that constraint. Inference runs on an AI model inside your building, on hardware you own. Documents never move off firm-controlled storage. The only thing that changes is how fast your lawyers can work through a file.
AI on your matters — private to your firm
Lotus is a viable alternative to Harvey and Legora for firms that want the same core capability — assistant, matter workspaces, contract review grids, and firm playbooks — without vendor lock-in or per-seat pricing that rises every year. Upload the documents for a matter, ask questions with cited answers, run structured review across the set, and work from an app on your desk.
The document intelligence partners expect from leading legal AI — matter workspaces, cited answers, contract grids, and playbooks — without sending confidences to tools your firm may not allow.
Documents stay under your roof, with an app on your desk — aligned with confidentiality, ethics, and how partners expect client data to be handled.
No vendor lock-in and no annual per-seat pricing that climbs every renewal. Lotus includes the full source code — auditable by your firm, with no ongoing license fee.

Select any screen below for a closer look at what you would use on a typical matter.
Most firms have ten or more years of precedents, past matters, correspondence, and research sitting on a file server that nobody can actually search. A colleague's folder structure only makes sense to them. A matter from 2019 might as well not exist.
Lotus includes a process that runs on your server overnight and works through your existing documents — every contract, brief, memo, and filing on your shared drive or NAS — and makes them interactive. Any associate or partner can then open Lotus and ask questions across the firm's entire history. Not just the matter in front of them. Everything your firm has ever written.
“What indemnity language did we use in our last five acquisitions?”
Lotus surfaces the relevant clauses from five past matters — each one cited with the document name, matter, and exact passage. Thirty seconds instead of two days.
Point Lotus at your NAS or shared drive. It works through every document overnight — no manual uploads, no reorganising your folders.
Each document is processed on your server. Nothing leaves your building. New files added to the server are picked up automatically on an ongoing basis.
Any lawyer opens Lotus Desktop and asks questions across the firm's full history — past matters, precedents, correspondence — with cited answers pointing to the exact source.
A single server on your office network — a dedicated PC or Mac Mini — runs the Lotus API, the AI, and all your data. Lawyers open Lotus Desktop on their Windows or Mac machines and connect to it like any other office application. Documents upload through the app; files stay on the server.
One box — a Mac Mini or Windows PC — runs the Lotus API, the AI, and your documents. Sits on your existing network like any other server.
Lawyers install Lotus on their Mac or Windows machine. It connects to the office server. No browser tabs. No cloud account. Just software.
Open a matter, upload documents, ask the assistant questions with cited answers, run tabular review across the set, export to Excel.
Lotus Admin runs on the server. Add lawyers, check service health, manage AI models, restart services — without calling a vendor.
Every lawyer account is created and managed through Lotus Admin — a desktop app that runs on the server itself. No vendor portal. No support ticket to add a user. Your IT contact (or ours, on the care plan) adds lawyers, checks service health, manages AI models, and controls storage from one screen. Everything is fully documented — admin app and lawyer-facing app both.
Lotus Legal is a one-time purchase. You own the source code. No per-seat annual pricing. No renewal conversation every year. No vendor lock-in.
Full source code, Lotus Desktop for Mac and Windows, Lotus Admin, office deployment runbook, and 90 days of onboarding support.
Optional. For firms that want someone on call — monthly releases, priority support, and a real person when something needs attention.
We run a live demo on a Mac Mini — real documents, the full desktop experience, everything your lawyers would actually use. No slides. Book a time and see it for yourself.
