vs Spellbook, Harvey, Legora, CoCounsel

The cloud legal AI alternative.

They’re excellent platforms. They’re also enterprise platforms.

Muet is one Mac app, one annual invoice, no procurement.

What these tools are for

Spellbook is a Word add-in for contract drafting and review, popular with solo and small-firm practices. Harvey is a full legal-operations platform for AmLaw and large in-house teams. Legora is enterprise multi-document review for M&A diligence and portfolio audits. Thomson Reuters CoCounsel is integrated into Westlaw and aimed at mid-to-large firms.

They are real, capable, and well-engineered. They are not what this page is arguing against.

What they share

All four are cloud-first by design. Documents are processed on the vendor’s infrastructure (Microsoft Azure, in Harvey’s case; other providers for the rest). All four require seat minimums or enterprise contracts. All four require a DPA, a sub-processor list, and the ability to negotiate procurement and security terms. Most require a sales call to even see real pricing.

What that costs

  • Spellbook. Around $149–$199 per seat per month for the Professional and Enterprise tiers, with Enterprise starting at 10 seats. A 5-lawyer firm: roughly $5,000–$12,000/year.
  • Harvey. Indicative pricing in the range of $40,000/year for ten users; some published estimates put the per-lawyer cost at $1,000–$1,200/month with twenty-seat minimums. Enterprise contracts only.
  • Legora. Around $3,000 per user per year, ten-seat minimum, $30,000 annual contract minimum.
  • CoCounsel. Roughly $225+ per seat per month, sold through Thomson Reuters sales motion.
  • Muet. $390 per device per year. One device, one license, one annual invoice. No minimum, no contract, no procurement.

What each does well

Each of these tools is good at the workflow it was built for:
  • Spellbook. Firm-wide playbooks, clause libraries, and high-volume contract drafting inside Word. If the firm draft hundreds of NDAs a month, this is the tool.
  • Harvey. Multi-document review at scale (Vault handles 100,000-document repositories), configurable workflows, and the SSO/audit-log/IP-allowlist set an AmLaw IT team expects.
  • Legora. Structured tabular extraction across thousands of documents at once. M&A diligence and portfolio review.
  • CoCounsel. Integrated legal research inside the Westlaw ecosystem. If the firm already lives in Westlaw, the integration is real value.

Muet doesn’t try to be any of these. It’s a different shape of tool for a different shape of work.

The work the firm's AI tools never see

Even at firms that have already deployed Harvey, Legora, or Spellbook, partners and senior lawyers regularly handle a class of documents that don’t go into the matter system at all:
  • Pre-engagement pitches and rainmaking correspondence before a matter is opened.
  • Off-the-record calls and internal notes the partner is working through.
  • Internal investigations the partner is personally running.
  • Sensitive HR and partner-track matters they don’t want associates touching.
  • Recruitment correspondence and lateral-hire negotiations.
  • Equity, succession, and partnership disputes.
  • Board work for outside organisations the partner sits on.
  • Communications with their own counsel.

Right now this work either gets pasted into a personal ChatGPT account, or it doesn’t use AI at all. Muet is what fits there: on the partner’s laptop, alongside the firm tools, for the work the firm tools were never going to handle.

What Muet adds, regardless of firm size

  • No third party sees the document. Processing happens on the lawyer’s Mac. No vendor in the loop for the work itself.
  • No DPA, no sub-processor list. Because there’s no processor relationship, there’s nothing to negotiate. Useful when the work involves a corporate client whose security team would otherwise need weeks to clear a new vendor.
  • Works offline. Plane, tunnel, regulated facility, weak Wi-Fi: the work continues.
  • Costs $390 per Mac per year. One-line software expense, no procurement cycle, no seat negotiations.
  • Sits next to whatever else you use. Most lawyers run several tools. Muet handles the work the others can’t.

Where Muet fits, by firm shape

  • Solo and 2–9 lawyer firms. Often Muet alone, because the price-to-privacy ratio is hard to beat and the firm doesn’t have the deal volume to justify Spellbook or the procurement weight to deploy Harvey.
  • Mid-size firms (10–100 lawyers). Often Muet alongside Spellbook: Spellbook for the contract drafting workflow, Muet for everything else partners handle that the matter system never touches.
  • AmLaw and large in-house teams. Muet on partner laptops alongside the existing Harvey, Legora, or CoCounsel deployment. The firm tools handle matter work; Muet handles the personal-laptop work the firm tools were never going to see.
  • Civil-law EU practices. Muet often as the only AI tool, because secret professionnel and §203 StGB make cloud-based options legally awkward in a way they aren’t in the US.
  • In-house counsel. Muet for investigations, NDAs, and pre-deal work. Whatever cloud tool the company has bought is rarely cleared for those.
