Terms of service

Effective 2026-07-16 · PlainLanguage.us is a product of extrAIntelligence LLC

These terms are short because the deal is simple: you pay for what you use, either as a flat monthly plan or per operation, we provide plain-language legal term information from our own structured data, and we keep the rules clear for both sides.

What the service is

PlainLanguage identifies known legal terms in text you provide and returns plain-language renderings from a curated glossary, through a web workspace and an API. An optional export helps you continue with your own AI tools, outside our service and under your own accounts.

What the service is not

It is not legal advice. PlainLanguage.us provides suggestions for legal terminology: they help you understand wording, they don't tell you what to do, and they are not a substitute for a lawyer. For decisions that matter, involve one.

Plans and billing

• Workspace ($49/month): a flat plan with 7,500 term matches a month. Each legal term found in text you submit counts as one match against the allowance; usage checks and term detail cards are not metered. If you use up a month's term matches, requests pause until the period resets. We never bill overage.
• Developer API ($0.0025 per operation): no monthly fee and no minimum; you are billed monthly, in arrears, for the operations you used. What each request costs is published in the API documentation's operation table, every response reports what it just cost, and your running total is free to check at any time. A month with no usage bills nothing.
• Enterprise arrangements (setup fee plus metered billing) are agreed individually in writing; these terms apply except where that agreement says otherwise.
• There is no trial and no free tier. The public demo on the homepage is free to use within its posted limits, without an account.
• Cancel any time through the self-serve billing portal; Workspace service continues to the end of the paid period, and a canceled Developer subscription is billed once more for any operations already used.

Your API key

The key is shown once. You're responsible for keeping it secret. Anyone holding your key can use the service as you: on the Workspace plan that spends your monthly allowance, and on the Developer API it runs up operations billed to you. If it may have leaked, roll it immediately. The old key stops working the moment the new one is issued.

Acceptable use

• Don't resell raw API access or systematically extract the glossary to build a competing dataset.
• Don't send us content you have no right to process.
• Don't probe, overload, or interfere with the service.

Your content

Text you submit stays yours. We claim no rights to it, we don't store it, and we process it only to return your result (see the privacy policy).

Warranties and liability, plainly

The service is provided "as is". We work hard on the glossary's accuracy, but legal language is contextual and we can't promise a rendering fits your situation. To the extent the law allows, our total liability for any claim is capped at what you paid us in the twelve months before the claim.

Changes and contact

If these terms change materially, we'll post the change here with a new effective date and, for subscribers, say so by email. Questions: hello@plainlanguage.us.
