FFilevine LOIS

Filevine LOIS is the legal AI agent to shortlist if your firm already runs its cases in Filevine. Built on structured data from more than 40 million legal matters, according to Filevine, it can scan every open case for work that is due and then write tasks, deadlines and draft documents straight into each matter. A free version and a 90-day trial make it cheap to test.

Platform commitment and price are the main points to plan for. LOIS does its best work on live Filevine data, paid plans are quote-only, and reviewers describe Filevine implementations that take time and budget. We rate it 8.3/10 on our scale. We have not used LOIS ourselves; this review draws on Filevine’s announcements, legal trade press and public user reviews.

Public Figures Behind Filevine’s Agent Layer

Filevine is a large, well-funded legal software company, so LOIS comes with more public figures than most new legal agents. These are the ones we confirmed on the source pages.

For a buyer, the 40 million matters and 6,000 firms describe the data behind LOIS, not proof that it will be accurate on your files. The more practical numbers are the free-tier limits: 5 GB files and 15,000-page documents are enough to test LOIS on a real closed case before any contract talk.

The Capterra figures rate Filevine as a whole. They tell you how firms feel about the platform LOIS depends on, including its implementation burden, which matters as much as the AI if you are not a Filevine customer yet.

Agents Sitting on Filevine’s Case Management Record

LOIS is a layer of AI agents on top of Filevine’s case management platform. Filevine describes the platform as the system of record that connects matters, documents, contracts and workflows, and LOIS reads from and writes to it.

From One Task to the Whole Firm

Most legal AI tools help one lawyer with one document. The LOIS console, launched on June 2, 2026, is built to run across every matter in the firm. Filevine’s example is a lawyer asking which open matters need a demand letter this week; the console finds them and drafts are ready for review within minutes, according to Filevine.

Tasks, Deadlines and Drafts Written Back to the Case File

• Write back to the case file: tasks, deadlines, calendar updates, generated documents, refreshed contact records and reports.
• Read large document sets: a pre-processing pipeline lets LOIS analyze very large volumes in one pass. Kopka Law Group says it turns a 5,000-page claim file into a few hundred pages of summaries.
• Check and flag: citation checks against case law, case file analysis and privilege issue flagging.
• Draft responses: LOIS drafts documents and answers from live case files, notes, calendars and custom fields.
• Route questions: intent-aware routing sends each request, such as summarizing a deposition or calculating a deadline, to the best-suited capability.

Related Filevine Tools

Timely automates jurisdiction-specific deadlines. MedCron turns medical records into searchable, exportable medical chronologies, which matters for personal injury and mass tort work. Depositions by Filevine was shown at LEX Summit 2025 with a full live deposition.

Uploading a Closed Matter to the 90-Day Sandbox

• Test first: request LOIS Explore or the 90-day trial at Filevine’s LOIS page and upload a closed matter to the isolated sandbox.
• Compare outputs: check summaries, citations and privilege flags against work your team already did by hand.
• Connect live data: moving to paid use connects LOIS to active case data and lets teams collaborate and save custom prompts.
• Set review rules: decide which generated tasks, deadlines and documents need attorney sign-off before they go out.

Cited Evidence So Lawyers Can Check Each Answer

Lawyers stay responsible for every filing and letter. Filevine pairs answers with citations and excerpted evidence so they can be checked, and one mass torts attorney quoted by Filevine says his team still verifies sources. Deadlines that LOIS calculates should be confirmed before anyone relies on them.

Free Access Terms Published, Paid Rates by Quote

Filevine publishes free access terms for LOIS but no paid prices. These are the options as described in Filevine’s announcements and legal trade press in 2026.

The free tiers are generous enough to test on real documents. The real cost decision is the paid contract, which usually means Filevine case management as well as LOIS.

From a $0 Test to a Reviewer-Reported Paid Figure

Filevine does not publish paid rates, so these scenarios use the free terms and one reviewer-reported figure. They are illustrations, not quotes.

• A firm testing before buying: $0 for 90 days. Budget staff time to load one or two closed cases and compare LOIS output with your own work product.
• A firm moving onto Filevine: one Capterra reviewer reports about $60,000 in total for the program, implementation and training. Spread over a three-year term, that is $20,000 a year, or about $1,667 a month.
• An existing Filevine firm adding LOIS: ask for the LOIS line item separately, plus any MedCron or deposition add-ons, so you can compare it with standalone tools such as Supio or EvenUp.

When you ask for a quote, list the matters, users and add-ons you expect in year one and again in year three, so you can see how the bill grows with the firm.Other costs include migration from another case system, training, add-ons that reviewers say accumulate, and the time to review AI drafts. LOIS Explore deletes accounts, documents and chat histories when the free period ends, so plan exports if you want to keep test results.

Filevine LOIS Compared With EvenUp, Supio, Eve and Clio Work

LOIS competes with plaintiff-focused AI tools on medical records and demands, and with general legal AI built into practice management.

The rivals below are the ones Filevine buyers most often weigh. Three of them focus on plaintiff work, which overlaps with Filevine’s heaviest users, and one is built into a competing practice management system. Prices are from our own listings for each tool, and most of this market sells through demos and quotes rather than public price lists, so comparing total cost means collecting written quotes from each vendor for the same caseload and the same set of features.

EvenUp, Supio and Eve are standalone plaintiff tools that sit beside your case system. LOIS is different because it lives inside the case system and turns results into calendar entries and tasks. That makes it a better fit for Filevine firms than for firms on other systems. Clio Work is the closest structural match for firms on Clio.

Existing Filevine Firms and Mass Tort Practices

• Current Filevine customers: LOIS acts on the matters, calendars and contacts you already keep there, with no separate integration.
• Personal injury and mass tort firms: MedCron chronologies, demand-letter drafting and very large document reads match the heavy records load of this work.
• Firms with many open matters: the console’s value grows when one question can be asked of hundreds of cases at once.
• Teams that want to test before talking to sales: LOIS Explore and the 90-day trial need no credit card.
• Defense and insurance firms with long claim files: Kopka Law Group’s 5,000-page example shows the kind of file LOIS is built to compress.

Clio Users and Solo Lawyers Who Only Want Research

• Firms happy on Clio or another case system: the paid value depends on Filevine, so a full platform switch comes with it.
• Solo lawyers who only want research: a standalone research assistant is simpler and likely cheaper.
• Buyers that need list prices: paid LOIS is quote-only.
• Large transactional and corporate practices: tools such as Harvey or Legora focus more on drafting and diligence for big-firm work.

Platform Commitment and Setup Effort Reported on Capterra

• Platform commitment: LOIS writes into Filevine. Leaving later means moving both your data and the workflows built around the agents.
• Implementation effort: Capterra reviewers describe setups that needed dedicated staff or outside help.
• Early AI features: one reviewer felt some AI capabilities were promoted ahead of what they delivered and that early medical chronology and demand products did not meet expectations. Test the current version on your own files.
• Total cost: reviewers say add-ons and third-party tools push the total up, and one cites a no-refund policy.
• Free-tier deletion: LOIS Explore permanently deletes accounts, documents and chat histories when the free period ends.
• Vendor claims: Filevine says LOIS is the only AI able to coordinate the work of running a firm. Confirm that on your own caseload during the trial.

LOIS Explore Arrives Free in August 2026

• August 2026: Minnesota Lawyer reported that Filevine launched LOIS Explore, a free version of LOIS, with uploads not used to train AI models.
• Summer 2026: Filevine opened a 90-day free trial of LOIS with no credit card, migration or commitment.
• June 2, 2026: Filevine launched the LOIS console for running AI agents across every matter in a firm.
• October 2025: Filevine unveiled LOIS at LEX Summit 2025, previewing a conversational AI workspace with source citations.

A Serious Pilot for Firms Already Running on Filevine

For firms that already run their cases in Filevine, LOIS is worth a serious pilot. It scores 8.3/10 on our scale; published pricing and more value outside Filevine would lift it. Its strongest point is that results become real work items: tasks, deadlines and drafts in the matter, rather than answers in a chat window.

Filevine’s $400 million raise in September 2025, with Insight, Accel and Halo Fund, suggests the product will keep getting investment. For firms on other systems, the decision is really about switching case management. Use the free tier on closed matters first, get a written quote that separates LOIS from the platform and add-ons, and check references on implementation time.

The LOIS Name, Free Access and Training on Case Files

What Does LOIS Stand For in Filevine?

LOIS stands for Legal Operating Intelligence System. Filevine unveiled it at LEX Summit 2025 and launched the LOIS console, which runs AI agents across every matter in a firm, on June 2, 2026.

Is There a Free Version of Filevine LOIS?

Yes. LOIS Explore is free for people with verifiable law firm contact details and covers research, document analysis, drafting and semantic search, with files up to 5 GB. Filevine also offers a 90-day free trial with no credit card. Accounts and documents are deleted when free access ends.

Does Filevine Train AI Models on Uploaded Case Documents?

Filevine says documents uploaded to LOIS Explore are not used to train AI models. LOIS answers include source citations and excerpts so lawyers can verify them. Firms should still review Filevine’s contract terms for paid use with live client data.

Can LOIS Work Without Filevine Case Management?

You can test LOIS Explore on uploaded files without moving your cases. Connecting LOIS to active case data, collaborating across teams and saving custom prompts require paid services, and the console writes its results into Filevine matters.

How Does Filevine LOIS Compare With EvenUp and Supio?

EvenUp and Supio are standalone tools focused on personal injury records and demands. LOIS covers similar records work through MedCron and drafting but runs inside Filevine and writes tasks and deadlines into each matter. Firms not on Filevine may find a standalone tool easier to adopt.
