You Went Solo for Freedom. You Inherited a Second Job.
You chose solo practice for independence. But the day fragments — switching between matters, reconstructing case facts from memory, hunting for that one email you know you saw. Five of every eight hours disappear into work that never reaches an invoice. Going independent gave you control, and a second full-time job nobody warned you about.
Inbox overwhelm
Important case details buried in hundreds of emails. Every time you switch matters, you're rebuilding context from scratch — reconstructing the timeline, the parties, where things left off. The mental cost is enormous.
Deadline anxiety
Manually tracking deadlines, court dates, and statutes of limitations across multiple cases. You carry it all in your head. Things slip through the cracks because you're the only one watching.
Drafting from scratch
Rewriting the same documents over and over, even when the pattern is similar. AI exists, but the best AI colleagues chase big law. What's left for solos requires you to rebuild context from scratch every single time.
What Your TwinCounsel Does
An AI colleague that knows your practice — it handles the admin and drafts real legal work, the way you would do it yourself.
Knows your practice
Connect your email and it maps your active matters automatically — parties, timeline, deadlines, every fact cited to its source. No data entry, no onboarding questionnaire. It knows what you're working on before you ask.
Builds your playbooks
It learns how you handle each kind of work — your clause positions, your intake flow, your voice — and turns it into playbooks it can run. So what comes back sounds like you, not a robot.
Handles the admin
Inbox triage, intake, client follow-ups, status updates — the reactive back-and-forth that fills five of every eight hours and bills as zero. You stop being the bottleneck.
Drafts real legal work
Memos, contract redlines, demand letters, client updates — generated from your matter context and run through your playbooks. Not a generic template. Your work product, ready to refine.
Shows you how your practice runs
For the first time, see it whole: which matters are active, what's overdue, where your time actually goes, and where capacity is recoverable — a real baseline to measure against.
See It in Action
Watch how TwinCounsel works — starting in your inbox
Your first matter, in minutes
Watch TwinCounsel read 147 emails and come back with a summary, the deadlines you might have missed, and what to do next.
What you're seeing: TwinCounsel connects to your inbox, identifies cases from your email patterns, and builds a comprehensive case summary — surfacing deadlines you might have missed and recommending next steps. Every fact links back to a specific email.
How It Works
Get started in minutes. No new software to learn. Just delegate.
We set up your twin
We connect your email (read-only to start) and stand up your twin for you — your playbooks, your integrations, a privilege-safe environment. No configuration on your end; TwinCounsel sees only the matters you assign, and your other emails stay private.
Assign a client
Reply with a client name. TwinCounsel finds the relevant emails and builds a complete picture — parties, deadlines, documents, history. No more reconstructing the matter from memory every time you switch.
Delegate and review
Get daily briefings, delegate drafts, review cited work product. You're the editor, not the author — you stay in flow on the work that matters. The more you use it, the better your legal twin understands your practice.
Complete Provenance. Complete Auditability.
Every fact is traced to its source. Each output passes automated QA before your review.
Every fact traced to its source
Click any fact to see the original email or document. Never wonder where information came from. Complete provenance for every detail.
Automated QA before your review
Each output passes quality checks before reaching you. The system flags uncertainties and highlights areas that need your attention.
A reflection of the attorney
Any corrections you make, your legal twin learns from. Over time it becomes a reflection of your practice — your writing style, your matter types, your preferences. You're not training a tool. You're building a colleague.

The Rise of the Solo.
You chose the solo path for independence — control your time, pick your clients, build something yours. But somewhere along the way, the day got fragmented. Context switching between matters. Reconstructing the same case facts over and over. Carrying every deadline in your head because there's no one else watching. You're in reactive mode, running just to stay in place. Going independent gave you control — and a second full-time job nobody warned you about.
TwinCounsel exists to close that gap. Your legal twin handles its share of the practice — the context, the details, the follow-through — so you can operate with the leverage of a big firm without giving up the independence you went solo for.
Your TwinCounsel, Ready to Work
Delegate the admin and the real legal work in plain English. Your legal twin already knows the matter — a case or a deal: the parties, the timeline, the documents, your preferences. Whatever you practice.
Triage your inbox
"Go through my inbox — what needs me today, what can wait, and what can you handle?"
New-client intake
"Draft an intake reply to this new client and open a matter from the thread."
Chase what's owed
"Chase the clients and counsel who still owe me documents this week."
Contracts & motions
"Draft a mutual NDA from our standard form" — or "an opposition to the motion to compel."
Review & redline
"Redline this vendor's SaaS agreement against our standard positions and flag anything off-market."
Deadlines & closings
"What deadlines and closing dates do I have this week across all my matters?"
Client updates
"Draft a client update on where the lease negotiation stands and the next steps."
Find that email
"Find the email where the other side agreed to the indemnity cap."

FAQ
Everything you need to know about TwinCounsel
What is TwinCounsel?
What is TwinCounsel?
TwinCounsel is your legal twin — an AI colleague purpose-built for solo and small-firm attorneys. It connects to your email, reads your matters, and handles its share of your practice. Delegate in plain English — drafting, tracking deadlines, summarizing case facts, finding that email. You're the editor, not the author. Every fact is cited back to its source.
What makes TwinCounsel different from other legal AI?
TwinCounsel is the only legal twin that works from your email — where decisions are actually made and documented. Harvey chases big law. Clio is a dashboard that requires data entry — another task, not a solution. ChatGPT starts cold every time — no case memory, no privilege safeguards. TwinCounsel is different: your legal twin reads your email, knows the parties, the timeline, the documents, and your preferences. You delegate by reply. Every fact traced to its source.
Why email instead of another software platform?
Your inbox is where legal work already happens — client communications, opposing counsel, court notices. Why force you into another platform? With TwinCounsel, you delegate by reply in plain English. No learning curve, no new interface to master. Just reply like you would to a colleague.
How It Works
How does TwinCounsel work?
Connect your email with read-only access. TwinCounsel reads your matters and builds a complete picture of every case — parties, timelines, documents, and deadlines from your existing communications. Then delegate by reply: 'Draft an opposition to the motion to compel' or 'What deadlines do I have this week?' You get back cited, auditable work product. You're the editor, not the author. Any corrections you make, your legal twin learns from.
How does my legal twin know my cases?
Your legal twin reads your email — threads, attachments, and calendar — and builds a complete picture of every matter: parties, timelines, documents, deadlines, and your specific preferences. This isn't generic AI that starts cold every time. It's a colleague that already knows YOUR cases, YOUR clients, and YOUR practice — working from your inbox, learning from every correction you make.
How long does it take to get started?
Minutes, not months. Connect your email (Gmail or Outlook) with read-only access, and TwinCounsel immediately starts building a complete picture of your matters from your existing emails. No data migration, no manual setup, no organizing files first. Everything you need is already in your inbox — just scattered and unsearchable. TwinCounsel changes that.
Trust & Security
How can I trust the AI's work product?
Complete provenance, complete auditability. Every fact your legal twin surfaces is traced to its source email or document — click to verify. Each output passes automated QA before your review. You're the editor, not the author — you see exactly where information came from and can drill into the details. You remain fully responsible for everything that goes out the door. That's what privilege-safe means.
How is my confidential client information protected?
TwinCounsel is privilege-safe by design. Every agent runs in an isolated sandbox — it can't touch anything outside its case. Starts with read-only access to your email; you control what goes out, and nothing is sent on your behalf without your approval. No training on your data. Pursuing zero data retention with LLM providers. AES-256 at rest, TLS 1.3 in transit. US data centers only. Building to SOC 2 Type II and ISO 27001. Designed from day one for attorney-client privilege.
TwinCounsel is built on Claude — why not just use Claude directly?
TwinCounsel is built on Claude, so as Claude improves, your legal twin improves. What we add is what makes it usable for a law practice: your matter context organized and cited, playbooks built from your own work, and privilege-safe isolation with a full audit trail. And the floor nobody mentions — Claude Pro and Team don't have Zero Data Retention turned on. TwinCounsel runs ZDR with every model provider, so privileged client work is never used to train a model or retained beyond a single request.
Getting Started
What do I need to get started?
An email account (Gmail or Outlook) and cases that need attention. TwinCounsel works with your existing email — no special software, no hardware, no need to organize your data first. We handle that automatically. Currently accepting design partners for our private beta.
How can I become a design partner?
We're working with a small group of solo and independent attorneys to build the legal twin category together. Design partners get hands-on access to use TwinCounsel on real cases, regular check-ins with founders, and influence over product direction. Request an invite to see if it's a fit for your practice.
