Compare HAQQ vs Harvey AI, Clio, CoCounsel, Legora, Spellbook
Legal never went through real digitization. Then AI showed up.
Digitization and AI-ification are happening at the same time, on the same desk. Every layer is being rebuilt at once.
Ten company types are emerging. We mapped them - plus the Evaluators scoring everyone.
General-Purpose LLMs
What they are
- •General-purpose AI assistants
- •Prompt → text → copy/paste
- •Same answers for every firm
What breaks
- No jurisdiction control
- No firm standards or drafting logic
- No traceability or accountability
- Outputs are ideas, not submissions
But Grok 4.3 just won the Vals AI legal benchmark
Yes - and that's exactly the point. Foundation models keep getting smarter at legal reasoning. HAQQ rides that curve. The Justinian engine routes each task to whichever foundation model is currently best for it, per jurisdiction and matter type. When Grok 4.3, GPT-5.1, or Claude Opus 4.5 wins a legal benchmark, HAQQ customers automatically benefit - without switching products.
Vals AI tests foundation-model intelligence. HAQQ delivers legal work. A smarter Grok means a smarter HAQQ.
Grok 4.3 led Vals AI's CaseLaw v2 (79.31%) and CorpFin v2 (68.53%) in May 2026 - both benchmarks evaluate foundation models, not legal AI products.
Bottom line: Useful for brainstorming. Not acceptable for professional legal work.
Legally Trained LLMs
Claude + Legal Plugins
- No private legal libraries - relies on general knowledge
- Not built for eFirm-specific workflows
- No proprietary external sources or knowledge bases
- Not legally aware - thin plugins on top of a general-purpose model
- Your data may be used to train the model
- Not focused for legal purposes
Justinian Legal AI Engine
- System of record - every output linked to a matter, billed, and audit-trailed
- Private legal libraries built into the engine
- Purpose-built for eFirm-specific workflows
- Proprietary external sources & knowledge bases
- Legally aware - understands jurisdiction, risk & context
- Your data is private - we never train our engine on your firm data
- 100% focused for legal purposes
Bottom line: We put everything we know about how lawyers handle matters into our Justinian AI Engine. Legal plugins on top of general-purpose models are not enough.
