In their own words
CasePlus AI
CasePlus AI is web-based client intake software for plaintiff law firms, using a website widget and phone line to gather incident details and assess liability, damages, statute of limitations, jurisdiction, and insurance in real time. Its document-analysis add-on reads accident photos, police reports, and medical records, then estimates a settlement or verdict range with reasoning linked to those documents. A separate add-on drafts demand letters from intake conversations, uploaded files, and case-value analysis; the letters should be reviewed by an attorney. Lead data can be forwarded to Clio, Slack, Zapier, or a custom webhook. Starter costs $299 a month and Professional costs $499 a month; new customers can begin a 30-day trial without a credit card. The widget is installed with a script tag, and instructions cover WordPress, Squarespace, Webflow, Wix, and raw HTML. CasePlus says it does not train AI models on customer data or sell personal information. It also cautions that its AI output may be inaccurate and is not legal advice.
