Mar 1, 2026r/legaltechCriticizesLegal researchThe author, a former seller of legal research tools, says CoCounsel is usually bundled with Westlaw so firms do not know their real per-seat cost, that Harvey's lower tier is an entry point before an upsell, and that answer quality drops on long documents.open
Mar 1, 2026r/legaltechMixedLegal researchA former seller says CoCounsel looked good in scripted demos but gives inconsistent results on repeated research queries, though it has improved and works as a starting point rather than a replacement for research workflow.open
Mar 1, 2026r/legaltechValuesLegal researchArgues that with limited data sets and good prompting CoCounsel no longer shows high hallucination rates, and says a paralegal agent they built removed most of the human work on reporting tasks.open
Feb 28, 2026r/LawyertalkMixedSummarizationCoCounsel deposition summaries looked substantively accurate but all page numbers were wrong.open
Feb 28, 2026r/LawyertalkValuesGeneral useCoCounsel is a great tool for legal work, though it takes practice to get the prompting right.open
Feb 28, 2026r/LawyertalkCriticizesSummarizationCoCounsel deposition summaries were nearly useless, focusing on irrelevant facts and missing themes, so a law clerk is the better choice.open
Feb 28, 2026r/legaltechValuesDraftingCoCounsel cuts drafting time by 50-70% for solo practitioners, but hallucinations and ethics rules will slow adoption, so it is a tool and not a replacement.open
Feb 27, 2026r/legaltechCriticizesLegal researchSays hallucination rates on CoCounsel and Protege were between 30-50% and that hallucinations are unavoidable in large language models.open
Feb 26, 2026r/legaltechMixedDiscoveryCoCounsel can answer discovery requests and does medical summaries well, but it cannot Bates stamp, and Supio is better for AI intake.open

Feb 25, 2026r/legaltechMixedLegal researchWestlaw CoCounsel is ok at best: AI research good, drafting and chronologies passable; about $400/seat/month; eyeing Supio.open
Feb 24, 2026r/legaltechValuesGeneral useCoCounsel is best placed because it bundles with existing Thomson Reuters relationships and Westlaw content, while Harvey and Legora depend on delivering integrations and measurable quality.open
Feb 22, 2026r/legaltechCriticizesLegal researchCoCounsel cannot search and use case law in an agentic way, because its owner limits access to its main content advantage.open
Feb 22, 2026r/legaltechCriticizesGeneral useCoCounsel is horrifically primitive, though lawyers using AI assistance still beat lawyers working alone and data holders like Lexis have an edge.open
Feb 21, 2026r/legaltechValuesGeneral useIn the author's experience CoCounsel is better for litigation and research while Harvey and Legora are better for drafting, though the products are converging.open
Feb 21, 2026r/legaltechValuesLegal researchCoCounsel looks best in class because its answers come from Westlaw citations, whereas Harvey and Legora drawing only on firm libraries makes their drafting strength doubtful.open
Feb 21, 2026r/legaltechCriticizesDraftingCoCounsel could only draft individual clauses, not whole documents, when the author last spoke with its vendor.open
Feb 19, 2026r/legaltechCriticizesDraftingThe author finds the quoted per-seat price for the CoCounsel Legal package far above the website's own pricing and notes that its drafting skill does not consult legal sources, so references must be verified.open
Feb 18, 2026r/legaltechMixedGeneral useCoCounsel is a good tool but cannot fully guarantee privacy, and the author says locally run agentic tools perform better.open
Feb 18, 2026r/legaltechValuesGeneral useCoCounsel and Lexis have verifiable security certifications, so firms should pay for them rather than use consumer tools.open
Feb 18, 2026r/legaltechCriticizesGeneral useCoCounsel is just a wrapper around OpenAI models that charges lawyers premium prices for a few extra features.open
Feb 18, 2026r/legaltechValuesGeneral useCoCounsel cannot be replicated from scratch because it is built on Thomson Reuters data, which is what makes it valuable.open
Feb 13, 2026r/legaltechCriticizesLegal researchCoCounsel is not much better than basic GPT and still hallucinates even when connected to Westlaw, and Lexis is worse, while legal startups work on legal reasoning.open
Feb 11, 2026r/biglawCriticizesGeneral useStopped using CoCounsel because it is slow, and prefers vLex and Copilot.open

Feb 10, 2026r/biglawValuesLegal researchCoCounsel is good for directly legal work and does not hallucinate cases like ChatGPT, but is poor for non-legal tasks.open

Jan 19, 2026r/LawyertalkCriticizesGeneral useWestlaw's CoCounsel seemed completely useless during a trial, though other AI tools impressed the author for limited tasks like cataloging documents and first drafts.open

Dec 26, 2025r/legaltechCriticizesContract reviewAfter using Spellbook and CoCounsel, the author finds that interfaces encouraging automatic acceptance of changes hinder adoption, and a traceable checklist approach would be trusted more.open
Dec 24, 2025r/legaltechValuesDraftingCoCounsel is good at surfacing issues and suggesting language, but the lawyer still has to choose, reject and rework the output through several rounds before it is client-ready.open
Dec 23, 2025r/LawyertalkValuesSummarizationThe author avoids ChatGPT for case digestion and prefers legal-specific tools like CoCounsel and Spellbook because their output is easier to check and stays grounded in the filings.open

Dec 4, 2025r/legaltechValuesGeneral useAfter complaining about the CoCounsel rollout, they got Advantage added at the same price and call Advantage fantastic.open
Dec 4, 2025r/legaltechValuesLegal researchCoCounsel with Advantage is extremely accurate for complex research questions when used correctly, and Westlaw's free training made the difference.open
