Compare / CaseRead vs ChatGPT
CaseRead vs ChatGPT: a general assistant and a legal one.
ChatGPT is OpenAI’s general-purpose assistant. It writes, searches the web and works with the files you upload.1 CaseRead is AI legal research for solo and small firms: it cites what it found, and its Hallucination Shield checks the citations you give it. ChatGPT’s side of this comparison uses OpenAI’s own pages.
At a glance
ChatGPT is the broader tool and, at the low end, the cheaper one: Go is $8 a month and Plus is $20. Its plans page lists no legal citation checker or citator, and on the individual plans OpenAI uses your content to train its models unless you opt out.1 CaseRead does the narrower legal job: it searches your project files and the public law together and cites both, and its Hallucination Shield runs two checks on every citation. Your data isn’t used to train AI models; our AI providers’ commercial terms exclude it. You can also use CaseRead from ChatGPT, read-only.
Who ChatGPT is for
Anyone who wants one assistant for writing, analysis and research across every kind of work.
OpenAI sells individual plans (Free, Go, Plus and Pro) and business plans (Business and Enterprise). Its plans include file uploads, web search, deep research, memory and Projects. It runs on the web, iOS and Android.1
It is a general tool, and OpenAI’s usage policies draw a line at legal advice: they say you cannot use its services for the “provision of tailored advice that requires a license, such as legal or medical advice, without appropriate involvement by a licensed professional.”3 For a lawyer, that is a reminder about who owns the work, not a reason to avoid the tool.
Pricing: what is published
ChatGPT’s paid plans start below CaseRead’s Solo plan. The question is what the money buys for legal work.
ChatGPT Free is $0. Go is $8 a month, and OpenAI notes that plan may include ads. Plus is $20 a month, and Pro starts at $100 a month. Business starts at $25 per seat a month billed monthly, or $20 billed yearly, for teams of 2 to 200. Enterprise is sold through OpenAI’s sales team.1
CaseRead’s Solo plan is $149 a month, or $119 a month billed yearly, with unlimited research. Team is $199 per seat a month, or $159 billed yearly. The free plan gives you 15 research questions a month and 2 citation checks a day, with no card. Deep research comes with a paid plan. Paid plans start with a 14-day trial; checkout takes a card. Cancel anytime.
What ChatGPT does better
Breadth, and a low price for it.
- One assistant for everything. Drafting, summarizing and reasoning through a problem, in law or out of it, on the web, desktop and mobile.1
- Web search and deep research. Both are on its plans, with more deep research from Plus up.1
- A low entry price. Go is $8 a month and Plus is $20.1
- Your files, projects and memory. Upload files, keep work in Projects, and let memory carry context from past chats.1
- Connections to the tools you use. Business connects to Google Workspace, Slack, GitHub, Microsoft 365 and more, and the plans list Excel, PowerPoint and Google Sheets extensions.1
If you want one assistant for all of your work, ChatGPT is hard to beat on breadth for the price.
What CaseRead does differently
It is built for one kind of work: legal research that cites its sources, with a check on the citations.
- It cites where the law came from. Ask in plain English. CaseRead searches your project files and the public law together and cites both. Anything it can’t match to a source it retrieved is flagged, not asserted.
- Named sources. Statutes and regulations for federal law, all 50 states, DC and Puerto Rico, pulled live from CaseRead's public law database. Case law from the Free Law Project. Federal material from eCFR, the Federal Register and GovInfo.
- Two checks on every citation. The Hallucination Shield asks whether each source exists and whether it supports the claim, for up to 50 citations per run, from pasted text or a PDF, Word or scanned document. It warns when a statute is marked repealed or a case has known negative treatment. An automated screen, not a citator.
- It remembers the case. A project’s parties, key dates, positions and decisions carry across conversations.
- Word, with tracked changes. Edit Word documents in the browser, with AI revisions as tracked changes, or use CaseRead for Word in a side panel.
- No training on your data. Your data isn’t used to train AI models; our AI providers’ commercial terms exclude it.
And you don’t have to give up ChatGPT to use it. You can use CaseRead from Claude or ChatGPT, read-only.
Test both on the same case
Ask both the same question about a case you know well, and read what comes back as you would an associate’s memo.
Questions worth asking of each:
Does each answer cite a source you can open and read?
Paste a public filing with a citation you know is wrong. Which tool flags it?
Does the answer say where the law came from, and when it couldn’t find something?
Is a cited case still good law? Does either tool claim to know?
Ask about your own file and the statute together. Are both cited?
Check the data settings. Is your conversation used for training, and who chose that?
What does a month cost, and what does the plan include?
Next week, does it still know the parties and dates without being told again?
Can AI revisions arrive as tracked changes you accept or reject?
The honest bottom line
Use ChatGPT for general writing and thinking. Use CaseRead when the answer has to cite its sources and have its citations checked.
They also work together: you can use CaseRead from ChatGPT, read-only.
