"The Fact-Lock feature is a game-changer. I can finally trust an AI with a demand letter. It cut our prep time by at least 80% on the first case we tried."

Sarah K., PI Attorney · June 2026

"I used to spend a full week just building the medical chronology. Lexyno does it in minutes and links everything back to the page. My supervising attorney was floored."

David M., Paralegal · May 2026

"A powerful platform for sure. The POV reports are brilliant. My only issue is the hard page limit on the Professional plan; we have some cases that exceed 600 pages and have to be handled manually."

Brian T., Managing Partner · June 2026

"Lexyno doesn't just draft, it helps strategize. Seeing the case from the adjuster's POV before we even send the demand lets us patch holes we might have missed. It's essential now."

Jessica L., Associate Attorney · April 2026

Comparison

How it compares

Lexyno's primary advantage over generic AI legal tools is its Fact-Lock™ technology. While a standard AI might draft a demand letter faster than a human, it carries a high risk of hallucinating facts and figures, requiring tedious manual verification. Lexyno programmatically locks all data points to the source documents, making every claim 100% traceable. Pick a standard AI if you need a quick, rough draft for internal use and are prepared to fact-check everything. Choose Lexyno when you need a client-ready, verifiable demand letter that minimizes liability and withstands scrutiny from opposing counsel or adjusters.

The decision

Is it worth it?

Return on investment

At $899/mo for the Professional plan, processing ~5 cases saves over $6,000 compared to manual review costs estimated at $1,200+ per case.

Personal Injury attorneys and paralegals managing case files, medical record review, and demand letter drafting.

Effort to adopt

Easy for Pros

Built for

Best for Personal Injury law firms seeking to automate the creation of accurate, source-verified demand letters and medical chronologies.

In-Depth Overview

For PI attorneys, the risk of an AI inventing facts in a demand letter is a non-starter. Lexyno is built to solve this core problem. Its proprietary Fact-Lock™ technology programmatically locks all numbers, dates, and dollar amounts from the source documents *before* the AI drafts any prose. This means every figure in the final demand letter is 100% traceable to the specific page in the case file, eliminating hallucination and the need for manual fact-checking. Beyond simple drafting, Lexyno functions as a strategic partner. After ingesting thousands of pages, it doesn't just summarize; it helps you build the argument. You can inject your firm's unique strategies, like the 'Eggshell Plaintiff' rule, directly into the workflow. It also generates an 'Insurance Adjuster POV' report, which anticipates the defense's arguments and highlights potential weaknesses in your case, like gaps in treatment. This allows you to preemptively strengthen your demand letter, moving from reactive drafting to proactive strategy and negotiation.

Key Use Cases

⚖️

Draft a Verifiable Demand Letter in Minutes

Personal Injury Attorney

Upload thousands of pages of medical records and police reports. Lexyno extracts key facts and drafts a 16-section demand letter with every figure and claim linked directly back to the source page.

Instant turnaround vs. 10-20+ days manually

✓ Pros

Fact-Lock™ technology prevents AI from inventing figures, ensuring 100% traceability.

Generates POV reports to anticipate defense and insurance adjuster arguments.

Significantly reduces manual review time from days to minutes.

Allows firms to inject specific legal strategies (e.g., 'Eggshell Plaintiff') into documents.

Transparent credit-based pricing shows a clear cost-per-case.

· Cons

Hard page limits on Starter (400) and Professional (600) plans may be too restrictive for complex cases.

Starter plan lacks the Insurance POV report and Medical Summary features.

Credit rollover is only available on the Professional plan and is capped at 300 credits.

No perpetual free tier; offers a one-time 'Evaluation Access' for a single case.

⚡ Editorial Verdict

Lexyno is a powerful tool for PI firms, dramatically cutting down on manual review time with its verifiable Fact-Lock™ system. Its key strength is producing demand letters and chronologies that are traceable to the source, preventing AI factual errors. The main trade-off is the hard page limits on non-enterprise plans, which may be restrictive for exceptionally large case files.

Questions & Answers

Frequently asked questions

What do I get with Evaluation Access?

You get the complete Professional feature set with a one-time grant of 350 credits, enough for one full case with a 300-page limit. This allows you to verify accuracy on a real case.

Is the UIM demand really free?

Yes. Each third-party (3P) demand letter generation includes one free Underinsured Motorist (UIM) letter transformation, which adapts the introduction and settlement offer from your approved 3P letter.

What happens if my case exceeds the page limit?

The page limits (e.g., 400 for Starter, 600 for Professional) are hard caps. The platform will not accept cases that exceed these limits to avoid risking incomplete data analysis. For larger cases, you must contact sales for an Enterprise plan.

Do I lose unused credits?

On the Starter plan, credits reset monthly. The Professional plan allows you to roll over up to 300 unused credits to the next month.

Is Lexyno available for legal teams outside the US?

Lexyno's documentation does not specify geographic limitations, but its focus on US-centric Personal Injury law (e.g., UIM demands) suggests it is primarily optimized for the US legal system. Verify suitability for your jurisdiction with the vendor.

Can Lexyno handle complex medical histories for PI cases?

Yes, Lexyno is designed to process extensive medical records (up to 600 pages on the Professional plan) and generate a traceable, chronological medical summary. Its AI Strategy Engine can also incorporate arguments like the 'Eggshell Plaintiff' rule for pre-existing conditions.
