If you are fighting for your kids, you already know the feeling. The other side has lawyers. The law is buried in language nobody bothers to explain. And every tool that claims to help wants you to upload the most private documents of your life to someone else’s server.
OLC is the opposite of that.
OLC is a legal research workspace that runs entirely on your own computer. The statutes, the court rules, and the case law live on your machine. Your filings, your orders, your evidence live on your machine. When you ask a question, the answer comes back with a citation to a real source you can open and read. Nothing about your case is ever uploaded. Not to us, not to an AI company, not to anyone.
What you can do with it 🔗
Put your whole case in one place. Create a matter, add your PDFs (filings, motions, orders, reports, exhibits), and OLC reads and indexes everything locally. Even scanned documents: it reads the text off a photographed order or a faxed filing right on your machine, so it is just as searchable as a clean PDF.
Search your own record in plain language. Instead of scrolling through hundreds of pages, ask for what you need. “Where does the guardian ad litem contradict the earlier report?” “Every deadline the court set.” “Everything about the safety plan.” OLC finds it and shows you where it came from.
Find the cases that matter. Federal case law from the U.S. Supreme Court and the Courts of Appeals, ranked so the controlling authority comes first, works no matter where your case is. When you read a landmark decision, OLC hands you the holding, clearly labeled, not a random concurrence.
Look up the actual law. Install your state’s statutes, court rules, and published decisions as a library and search the full text offline. No paywalled database, no guessing which website is current. Libraries are available now for Maine, Nebraska and New Hampshire, with more on the way.
Ask an assistant that cites its sources. Connect your own Claude (through Claude Desktop) in one click, and it can search your case, the statutes, the rules, and the case law, and answer in plain language with a citation for every point. Prefer to keep even that on-device? Use the built-in assistant with a free local model. Either way, OLC’s engine never calls an outside AI service and it will not invent a case. If it cannot find support, it tells you, instead of making something up.
Your privacy is the product 🔗
This audience has every reason to be careful about who sees their files. So OLC is built around four plain promises:
- Your case files never leave your device. The engine makes zero calls to any AI service. Reading, searching, and organizing all happen on your computer.
- Public law comes to you. Statutes, rules, and case law arrive as signed download packages. Data flows in, never out.
- Your payment is never linked to your case. Checkout is handled by a separate payment provider. It only ever knows your email and that you bought a license. It knows nothing about your matter, at all, ever.
- You can see how it works. No hidden accounts, no telemetry, no fine print that quietly ships your data somewhere. Once activated, OLC runs completely offline.
How it works 🔗
- Download OLC for Windows, macOS, or Linux. It is free to download.
- Buy a license and paste the key that lands in your inbox. That unlocks the app.
- Add your case and drop in your PDFs. OLC indexes them on your machine.
- Connect your AI (your own Claude, or the built-in local assistant) and start asking real questions.
Pricing 🔗
$150, one time. That is the whole price. No subscription, no monthly fee, no account to log into. Your license is yours, it includes every future update, and once you activate it the app works with no internet at all.
Buy a license, $150 one time 🔗
Download OLC (free) 🔗
Download links by system: Windows | macOS | Linux
Download the app first, then activate it with the license key emailed after you buy. One license unlocks the app and every law library download.
Who it is for 🔗
OLC is for parents representing themselves or working alongside an attorney, and for the attorneys and paralegals who serve them, in family court, custody, and child protective services matters (DCYF, CPS, DCF, whatever your state calls it). The federal case law and your own case documents work no matter what state you are in. State law libraries are available now for Maine, Nebraska, and New Hampshire, with more on the way. If yours is not ready yet, you still get federal law and your full, searchable case file on day one.
A note on what OLC is, and is not 🔗
OLC is a research and case-organization tool. It is not a lawyer, it does not give legal advice, and using it does not create an attorney-client relationship. It helps you find and organize the law and your own records so you can make your own decisions or work more effectively with your attorney. For advice about your specific situation, talk to a licensed attorney in your state.
Common questions 🔗
-
Do you see my case files? No. Never. They stay on your computer, and the engine makes no calls to any AI service.
-
Do I need internet? Only to download the app and to install law updates. Everything else works offline.
-
Is my payment connected to my case? No. Payment runs through a separate provider and is never linked to anything about your matter.
-
What if I do not have a lawyer? OLC does not replace one, but it puts the same source material a lawyer would use directly in your hands, organized and searchable.
-
Is it a subscription? No. Pay $150 once. It is yours, with every future update included.
OLC is built by Cryptobyte, which makes private, on-device tools for people who cannot afford to have their most sensitive information leave their control.
