[ATTENTION]
The tab nobody at your firm ever clicks is a $300,000 invoice.
[INTEREST]
Per lawyer. Per year. In licensing fees.
→ Westlaw + CoCounsel (Thomson Reuters): $15,000–50,000 → Practical Law standard docs (Thomson Reuters): $10,000–20,000 → Contract Express playbooks (Thomson Reuters): $5,000–20,000 → LexisNexis + PSL (RELX): $8,000–25,000 → Definely / Kira contract review: $2,000–8,000 → iManage document management: $2,000–5,000 → Everlaw eDiscovery: $3,000–10,000 → Clio Insights + Grow: $1,000–3,000
Total: $46,000–141,000 per lawyer per year.
[DESIRE]
10 lawyers.
Low estimate: $460,000/year in licensing. High estimate: $1,410,000/year in licensing.
BigLaw (the open-source one): $0 in licensing. Plus your Anthropic API bill — roughly $100–300/month for a 10-lawyer firm.
Call it $2,400/year.
The spread is $460,000 vs $2,400. For the same research. The same redlining. The same precedents. The same matter health dashboard. The same @-mentionable agent in your Teams.
[ACTION]
curl -fsSL https://raw.githubusercontent.com/discover-legal/BigLaw/main/setup.sh | bash
That's the whole install.
[ALWAYS BE CLOSING]
Every line in that list above is a subscription you can cancel the day you run setup.sh.
Not all at once. One at a time. Start with whatever costs the most. Run a matter through BigLaw. Compare the output. Cancel what you cancel.
The bench will still be there tomorrow. It doesn't charge a renewal fee.
[DO LIKEWISE]
A senior associate billed 2,200 hours last year. Her firm paid $80,000 in Westlaw fees for her seat. The Westlaw subscription cost more than her bonus.
BigLaw gives that back.
Built on Mike (Will Chen) and Lavern (Antti Innanen)'s shoulders. Standing on the work of people who gave theirs away too.
Take it. Use it. Tell the next solo down the hall. Tell the boutique that just lost a pitch to a firm that could afford CoCounsel.
Run the math on your firm. Run setup.sh.
Go. Do likewise.

Launch post (primary)
I built BigLaw on the shoulders of two giants — Mike (legal document tooling) and Lavern (a roster of legal agents).
The name isn't irony. It's the point.
BigLaw firms spend $2M+ per year per seat on Westlaw, Practical Law, Contract Express, Clio Insights, Definely, iManage, and twenty tools nobody at a five-person firm can afford. BigLaw the platform consolidates all of it. Open source. Free. One curl command.
Big Michael is the agent who lives in your Teams and Slack. @-mention him in a channel: @BigMichael briefing Acme Corp and he launches a swarm of agents that pull from Clio, iManage, Teams, Slack, SharePoint, email, and your document store in parallel — synthesised into a single partner briefing before the call. The scattered-file problem — every matter spread across 10 mailboxes, 2 call notes, and 4 DM threads — that's what he solves.
🌉 The old line is "I've got a bridge to sell you." Mine's the opposite: I have a bridge to give you — and it stands upon the shoulders of giants. BigLaw bridges a $2M/year vendor stack into a single open-source platform that any solo or small firm can run on a $5 VPS. Free, open source, yours to cross.
(And yes: Claude built most of it with me. An AI building a multi-agent AI that argues with itself about the law. Turtles all the way down. 🐢)

Big Michael post — channel agent launch
Big Michael is now in your Teams and Slack.
@-mention him in any channel. He knows your matters.
@BigMichael status M-2024-001
→ matter health 87/100 🟢 · 2 active tasks · 1 pending gate
@BigMichael briefing Acme Corp
→ scanning 10 sources in parallel…
→ [posts back] Acme Corp — Partner Briefing: …
@BigMichael task review the force majeure clause in the Acme MSA
→ submitted · Task ID: tsk_01abc · use @status to follow progress
The briefing command is the one I'm most pleased with. Law firms have a structural problem: client information is scattered across Clio, iManage, email, Teams, Slack, and whatever else people actually use. Nobody has time to pull it together before a call. Big Michael runs a hub-and-spoke swarm — 10 parallel agent spokes pulling from every connected system at once — and synthesises it into a single briefing. Twelve seconds. One @-mention.
Part of BigLaw — open source, AGPL-3.0.

v0.5.0 post — The full feature drop
BigLaw v0.5.0 is the version that makes the BigLaw tool stack argument serious.
What Am Law 100 firms pay for. What this costs: $0.
→ Playbook-aware contract redlining — Definely / Kira / Luminance replacement. 3-step pipeline: Haiku clause extraction → Sonnet playbook analysis → Sonnet summary. Your playbook cascade (client > matter > personal > firm) applied to every clause, with tracked-change output.
→ Headnote extraction — Westlaw Key Numbers / LexisNexis headnote replacement. Sonnet extracts ratios, obiter, and procedural posture. Compounds over time as every processed opinion enriches the store.
→ Precedent generation — Practical Law Standard Docs / PSL replacement. Haiku structures the document; Opus drafts from your firm's knowledge store and playbook cascade. Your positions, your style, your knowledge — not generic market standard.
→ Four-tier playbook cascade — Contract Express / Practical Law replacement. client (3) > matter (2) > personal (1) > firm (0). Client requirements win. Firm defaults are the market floor. Override at any level.
→ Big Michael in Teams and Slack — channel agent with hub-and-spoke client briefing swarm. 10 parallel spokes (Clio, iManage, Teams, Slack, SharePoint, Drive, email), 12 s each, Promise.allSettled. One @-mention for a full partner briefing.
→ Hash-chained audit trail — every agent call, every tool use, every gate decision, every access denial. External system access attributed to the responsible lawyer by name. OpenSearch / Splunk / webhook forwarding.
→ Court deadline calculator — FRCP, UK CPR, EU Competition. Trigger date in, every downstream deadline out, cited.
→ One-liner install: curl -fsSL https://raw.githubusercontent.com/discover-legal/BigLaw/main/setup.sh | bash
Still on Mike (Will Chen) and Lavern (Antti Innanen)'s shoulders. Still AGPL-3.0. Still turtles all the way down. 🐢

Clio post — practice management integration
BigLaw now connects to Clio.
One OAuth flow. Four data regions (US, EU, Canada, Australia). Then:
→ Import a matter and its documents — BigLaw fetches the files, extracts text, classifies practice area, and kicks off a full bench run automatically
→ 7 agent tools: list/get matters, list/download documents, create time entries, post notes, list contacts
→ Time-entry sync: push BigLaw's billable time back to Clio activities, rounded to 6-minute billing units
→ Big Michael's briefing swarm pulls Clio intel into every client briefing automatically
Gated on CLIO_CLIENT_ID. Unconfigured, the tools register but sit quietly off.
AGPL-3.0.
