Privileged files stay on your machine.
AI reads them anyway.
Search every contract, summarise opposing briefs, and draft discovery responses — without uploading a single document, ever. Sery's AI runs on your matter files, on your machine.
The problem
Legal work is document work — and you can't upload your documents.
Privilege rules out the cloud
The ChatGPT and Copilot productivity gains everyone talks about require sending text to a third-party server. Attorney-client privilege and matter confidentiality say no.
Discovery and review still cost hours
Reading a 300-document production for one indemnification clause is the same job in 2026 as it was in 2006. The AI that could speed this up isn't allowed near the files.
eDiscovery vendors are overkill
Five-figure platforms for a five-document review. Onboarding takes longer than the work. Most matters never get the AI assist they'd benefit from.
How it works
AI on your matter files. Without your matter files leaving.
Install Sery Link on your practice machine
Native macOS, Windows, and Linux app. Point it at your matter folders — local drives, network shares, OneDrive, Box, SFTP. PDFs, DOCX, contracts, briefs, transcripts. Sery reads them all in-process on your machine.
Indexing happens locally, in seconds per document
A native Rust extraction layer pulls text from PDFs (including scanned ones via macOS Vision / Windows OCR), DOCX, and Excel. No document staging server, no cloud OCR endpoint, no third-party reader.
Ask in plain English — across years of matter files
With a Plus workspace, you get the AI agent. Ask "find every indemnification clause across the Henderson contracts", "summarise the opposing motion for Friday", or "draft a Rule 26 response from these chart notes". The model gets the relevant passages from your machine; the documents themselves never travel.
Add associates and paralegals to the same workspace
Pair every attorney machine in the firm with a workspace key. Search and reason across every matter file across every machine — without a central document repository to maintain, breach, or migrate.
What you'll do with Sery
The drudgework AI was made for — on documents AI was never allowed near.
Find
Every indemnification clause across years of contracts
Cross-matter clause search in plain English — "show me every limitation-of-liability cap under $1M in the last 24 months of deals." Indexes the language, not just the file names.
Summarise
A 200-page opposing brief into the issues you need by Friday
Paste the prompt, get a structured summary citing pages. The brief never leaves your machine — and you don't bill the client for a paralegal to first-pass it.
Draft
Discovery responses, deposition outlines, demand letters
Sery reads the matter file and produces a first draft in your firm's voice. You edit; you don't start blank. Hours saved per matter, not minutes.
Compare
Contract redlines and version drift across negotiations
"What changed between v3 and v7 of the master agreement, and why does it matter?" Sery reads both versions on your machine and answers — no document upload to a redlining service.
Reason
About precedent and strategy across your own matter history
"Have we faced this counterparty before? What did we agree to last time? Has any judge in our jurisdiction ruled on this issue in the files we have?" Your firm's institutional memory, finally searchable.
Privilege guarantee
Documents never leave your machine. Period.
Document contents stay local
PDF text, DOCX bodies, deposition transcripts, contract clauses — extracted in-process on your machine, never uploaded anywhere. Only the metadata and the answer travel.
AI sees only what the question needs
When you ask a question, Sery sends only the relevant passages to the model — not the whole document, not the whole matter, not the whole drive. You can review what was sent.
Verifiable audit log
Every outbound network event is logged locally. Show your client, your insurer, or your bar association exactly what left the machine and when.
AGPL-3.0 open source
The desktop client's source code is published. Your IT counsel and your malpractice carrier can audit the privacy claims — not just read them on a marketing page.
A note on privilege: Sery is built so attorney-client privilege is preserved by architecture — your documents don't reach a third party because they don't leave your machine. For firm-wide deployments, multi-jurisdiction matters, or specialised data-processing arrangements, contact us before rolling out.
Start on your next matter
Sery Link is free to install and use on a single machine. The AI agent and multi-machine workspace are $19.99/mo per attorney — 7-day trial, no card.
