Filevine has launched LOIS Explore, a free version of its Legal Operating Intelligence System that lets legal professionals test the company's AI tools without a credit card or long-term commitment. The platform handles legal research, document analysis, drafting, and semantic searches across uploaded materials, with support for files up to 5 gigabytes and documents as large as 15,000 pages.
For law firms, the free tier offers a way to evaluate legal AI on substantial case files before committing to a paid plan. Responses include citations that users can check against the underlying source material, and the platform can review case materials, verify citations against case law, and flag potential privilege issues.
How LOIS Explore works
Users can select litigation, transactional, or advisory settings to tailor the platform to their practice area. Filevine said LOIS was built using structured data from 40 million legal matters. The company also confirmed that documents uploaded to LOIS Explore will not be used to train AI models, and that accounts, documents, and chat histories are permanently deleted when each free-access period ends.
The free version runs in a separate testing environment. Firms that want to connect LOIS to active case data, collaborate across teams, or keep customized prompts need to contact Filevine about paid options. Access requires verifiable contact information tied to a law firm or legal business.
What the free tier includes
For legal professionals evaluating AI tools, the trial covers core tasks like reviewing case materials and checking authorities against case law. The 5-gigabyte file limit means users can test the system on realistic workloads rather than sample documents alone.
Paralegals and lawyers interested in how AI for document review and research fits into daily workflows can assess the platform's output quality firsthand. The development of such tools follows the broader rise of AI for Legal tasks like contract analysis and matter review, where accuracy and sourcing matter as much as speed.
Considerations for adoption
The free tier is strictly a testing ground. It doesn't connect to active case management systems, and prompts and collaborative features remain behind the paid tier. Firms should compare what they learn in the sandbox against their actual workflow needs before scaling up.
Privacy controls are a key part of the offer. The permanent deletion of uploaded material after each trial period reduces the risk of sensitive client data lingering in a vendor's system.
Why this matters for legal professionals
Most legal AI products require a demo call and a sales cycle before you can touch the software. LOIS Explore removes those barriers, letting attorneys, paralegals, and legal operations staff test AI tools on case files they already have. The skills gained from trying a platform like this carry across to other legal AI tools used in practice, and AI for Paralegals training covers the type of document review and research tasks LOIS Explore targets. The deletion of uploaded data and the requirement for verifiable firm contact information also signal how seriously the company treats client confidentiality in a space where privacy concerns are common.
