LegalSling

How LegalSling works

Level the playing field before you sign

Big companies have in-house lawyers who write contracts in their favour. LegalSling gives you a clear, objective reading of what you’ve been sent, so you can spend your lawyer’s time (and your money) on the parts that matter.

What happens when you upload a contract

  1. We read the text. PDFs, Word documents and pasted text all work. Scanned PDFs are read from the page images.
  2. We map the contract. Who the parties are, how the document is structured, and which law governs it.
  3. We explain every clause. What it says in plain English, what it means for each side, and which way it leans.
  4. We flag what may go too far. Red flags are terms that are markedly one-sided, unusual for this kind of agreement, or that may go further than the governing law commonly allows. “Worth a look” marks terms that are common but deserve a question.
  5. We check the AI’s work against the document. Every quote is looked up in the document text and every paragraph reference must exist. A quote that can’t be found is left out.

How the governing law is detected

LegalSling only takes the governing law from the document itself: its governing-law clause, or the courts or arbitration it chooses. You’ll see the exact words it relied on, with a link to the paragraph. If the contract doesn’t say which law applies, LegalSling tells you so rather than guessing, and lists any clues (such as where the parties are registered) as clues only.

It’s built for contracts governed by the law of England and Wales, Scotland, Northern Ireland, EU member states and US states. Contracts under other laws are still explained, with general context only.

What LegalSling is, and what it isn’t

LegalSling explains what a contract says and points out things to discuss. It doesn’t tell you whether to sign, what to negotiate, or what to do. It isn’t a law firm, it doesn’t give legal advice, and using it doesn’t create a lawyer–client relationship. It can also miss things or get things wrong, so check anything important with a qualified lawyer.

The best way to use it: read the analysis, add your own notes to the clauses that matter to you, then send your lawyer the brief. They start from a clear picture instead of billing you to build one.

Credits

LegalSling runs on credits, and you only pay for what you use. One credit is 1p. Each analysis uses credits in line with how much reading and explaining it takes, so a short agreement costs less than a long one. A question in the Ask tab uses about 64 credits on a typical contract. New accounts get 500 free credits once they confirm their email address, and the sample contracts are always free.

Before an analysis starts, you’ll see about how many credits it will use. We set aside the most it could cost and charge only what it actually uses; the rest comes straight back. If an analysis doesn’t finish you aren’t charged, apart from reading the pages of a scanned PDF if that part worked (you keep the text). When you need more, you can buy a pack of credits by card from the Credits page. Credits never expire.

Your documents

Your documents are private to your account. They’re sent to Anthropic’s Claude AI to produce the analysis. You can delete any document, or your whole account, at any time, and everything we stored about it is deleted with it.
