What makes LOIS different from other AI legal research tools

Every other AI legal research tool asks you to either trust a black box or waste time hunting down every citation. LOIS is built on the opposite premise: attorneys should have every tool at their disposal to build the strongest possible argument and stand fully behind every word they submit. What’s more, they should be able to do the work in one focused environment.

Built to Protect 

LOIS Legal Research was built to protect lawyers from risk while offering them the most powerful legal research tool on the market.

Every citation is automatically checked against a trusted, secondary verification layer, and every piece of reasoning is traced back to the exact page it rests on. All of this work is done in one focused environment, with no tab-switching required.

Instead of hoping your research is right, you can prove it is, allowing you to write and research with full confidence.

Powerful Legal Reasoning

LOIS Legal Research helps you build the strongest possible argument for your client. Here's what that looks like in practice.

Along with the benefit of increased thoroughness, however, using AI for legal research has created a growing malpractice risk: citing cases that don’t exist, or misrepresenting what real cases say. As AI tools spread through legal research, fabricated and misleading citations have slipped into filings. Courts are not treating it as a minor oversight; monetary sanctions, stricken filings, and bar discipline have been common.

LOIS Verifying_1080x1080

Research where you already work

No more toggling between your drafting workflow and a separate research tool. LOIS Legal Research lives inside your workflow. And because it's grounded in your actual case files as well as a trusted body of case law, it can reason across both, connecting the facts of your matter directly to the law that governs it.

legal-research-citation

Automatically check citations

Every citation LOIS generates passes through a trusted, secondary verification layer before it ever reaches you. Each one is linked directly to the underlying opinion for instant review. If a case can't be verified, LOIS flags it as a potential hallucination so you catch it, not opposing counsel or a judge.

Flagged Opinion_1080x0180

Quickly review reasoning

LOIS doesn't just cite a case; it shows its work. The opinion panel visually marks the exact passages LOIS relied on, opening directly to the relevant page in the original court opinion with the supporting paragraphs highlighted.

Spotlight Reasoning_1080x1080

Drill down to the holding

Most citators tell you whether a case is still good law. LOIS tells you whether a specific holding is. It scans case law to surface where a higher court has quietly narrowed, weakened, or contradicted that exact point, even in decisions that never cite the original case by name.

Chat with the opinion

Engage in a deep-diving conversation about any aspect of an opinion to pull out the nuances within it. Ask about procedural posture, specific issues the court addressed, or how a holding is qualified. Get answers scoped to that opinion alone.

LOIS Legal Research FAQ

Is there AI built for legal research?

Yes. Tools like LOIS are AI built specifically for legal research. That means the platform grounds its answers in verified case law instead of the open internet, so answers come back with real, checkable citations tied to actual source documents. This purpose-built approach is what makes the tool reliable enough for legal work, where accuracy and citation integrity aren't optional.

How can I check if a legal citation is real / correct?

Look it up directly in a verified case law database, or use a tool built with citation verification. LOIS runs every citation through a trusted, secondary verification layer and lets you review the exact passages its answers come from directly within the original court opinions, so you're not relying on the AI's word alone; you can see the source for yourself before it ever goes in a filing.

What's the best AI tool for legal research?

It depends on what you need. General AI chatbots like ChatGPT are useful for many contexts but aren't built for legal accuracy. They can fabricate cases and misstate holdings. Traditional platforms like Westlaw and Lexis have deep databases but weren't designed around AI-native workflows. LOIS is purpose-built for legal research: it combines AI speed with citation verification and passage-level review, so you get fast, source-backed answers you can actually verify and trust in court.

How much does an AI lawyer cost?

AI tools aren't lawyers and can't replace one. They're research assistants that make legal work faster. Pricing for AI legal research tools varies by provider and firm size; contact us for a quote tailored to your practice.

Is ChatGPT the best AI for legal advice?

No. ChatGPT isn't built for legal work. It has no connection to verified case law databases and has been shown to fabricate citations and misstate what cases actually hold, which has led to real sanctions in court. For legal research and advice, you need a tool designed specifically for the legal domain, with citation verification built in, which is exactly why LOIS exists.

What is better than ChatGPT for legal research?

Purpose-built legal research tools are better than ChatGPT for legal work, because they're grounded in actual case law and built with verification layers ChatGPT doesn't have. LOIS was designed specifically to solve the hallucination problem general AI creates by checking every citation and tracing every claim back to its source.
