What the record says · AI Vortex
The most named complaint is accuracy (38 of 155 voices); the most valued thing is time saved (17). The band crosses zero: the record does not say yet whether lawyers lean for or against it. 3 voices come from Hacker News, 115 from Reddit and 37 from Bluesky, Mastodon, Lemmy and Stack Exchange.
What they’re saying · verbatim, newest first
“If so, I demand your Bar Number because you offered negligent advice, like that and not to use Copilot, which I recently did, cross-checked by two more AIs to construct and file a complaint, so maybe I'm familiar with law, just a bit.”
“People have been doing contract review using playbooks with Copilot for a long time.”
“Copilot is deceptively expensive, especially Cowork”
in “Lawyers using ChatGPT: how are you protecting client data?” · 18 voices
ChatGPTValues“The contract is no different from them using any other tool out there.”open
ChatGPTCriticizes“A pivileged convo can get read by someone with zero duty to your client and you'll never know which is the risk to deal with.”open
“GPT will always spot something that Claude has got wrong or missed, and visa versa”open
HarveyNeutral“I think a big part of Harvey and Legora’s moat is trust by association.”open
ChatGPTValues“I personally see that as overkill given how much data attorneys regularly entrust to digital providers without that same standard.”open
ChatGPTNeutral“It's only the pure consumer level plans that require opt-out instead of defaulting to it.”open
ChatGPTValues“Both of these services default to not training on any of your chats or data rather than requiring you to opt out. So quite affordable.”open
ChatGPTValues“Both of these services default to not training on any of your chats or data rather than requiring you to opt out. So quite affordable.”open
“This ruling says nothing about attorneys using AI and confidential information, it just confirms that AI tools are just as valid for search by authorities as is google, facebook, or any other digital tool on your machine.”open
“Even the paid Claude AI consumer plans do not contain a confidentiality rider.”open
“Without a citation you verify everything; with one, only what's disputed.”
“I was working with someone who is fairly neutral on AI and was just incensed that Copilot couldn’t make a template for legal numbering.”
“My issues is only a fraction of our team has a Copilot license, Cowork now runs on metered pricing so we are not going to know what to budget for, and every time our team uses it we will be incurring an unpredictable cost.”
in “iManage vs Netdocs”
“Using 3 AIs, to crosscheck each other, but mostly Copilot in Word to create the document, I wrote a Civil Complaint, filed with fee waiver.”
“Use Copilot only for things you can verify from your own knowledge”
in “Is co-pilot good enough for in-house generalist?” · 5 voices
Values“Spellbook has been very helpful for first round edits/issues lists”open
Values“I've been using it since it came out in beta and it is phenomenal and plugs right into Word.”open
CopilotValues“Kinda/yes - it’s mostly just a wrapper There are rumors they’ve been testing kimi in copilot which outperforms Anthropic and OpenAI on the Harvey bench (legal benchmark)”open
HarveyValues“I got pretty good use out of it for review of multiple docs at the one time and large DD exercises and generally found it pretty good as a drafting assistant”open
“Copilot is fine for pulling CPs out of a credit agreement or purchase agreement to make the initial draft checklist, but pushing your team toward a dedicated closing management tool is what actually helps with the manual administrative grind.”
in “Transactional checklist, project management and tracking”
“GitHub Copilot Pro or GPT Pro for instance do not have privacy protection by default, but can have the option disabled for feeding into the model.”
in “How are you using AI with client data without freaking out about privacy?” · 13 voices
“We considered AWS Bedrock-claude, but cross-border issues, the need for agreements, and the fact that it is too hard relative to the local solution.”open
ChatGPTCriticizes“For anything with client names, IDs, medicals, or privileged notes, consumer ChatGPT/Claude is the wrong tier. Those plans can train on or retain inputs unless you have a written enterprise/API deal with zero retention.”open
HarveyNeutral“Harvey is not zero data retention. Harvey requires ZDR from the model providers it calls, which is a statement about what OpenAI and Anthropic keep, not about what Harvey keeps.”open
HarveyValues“Use a zero data retention system built for legal work (Harvey, CoCounsel, etc) and get client consent before using AI on their matters.”open
CopilotMixed“I’m not yet sure how Open AI’s Business plan compares, as I’m looking to switch to Codex due to GitHub Copilot burning tokens too quickly.”open
ChatGPTNeutral“Open AI for example has a difference set of security standards, terms, and policies for enterprise and business as opposed to their standard consumer levels.”open
“The business/teams version is protected by the same commercial agreement as enterprise.”open
ChatGPTValues“I do not understand the obsession with ZDR.”open
“Section B separately provides that the customer retains rights to Inputs and owns Outputs, and that Anthropic may not train on Customer Content.”open
“Check over the commercial terms and the data processing addendum for Anthropic. It’s actually quite reassuring.”open
HarveyValues“Using a vendor like Harvey is nice in part because they have a lot more negotiating power to get ZDR.”open
