# Contracts.io

> Un redactor de contratos con IA en la categoría "contratos de dos lados". Lex redacta el contrato a partir de una frase. Ambas partes negocian con un solo enlace para compartir (redlines, Aceptar/Contraproponer/Rechazar, versiones) y después firman electrónicamente. Cada parte tiene su propio Lex privado. La otra parte nunca paga.

- Contracts.io is an AI contract drafter in the category “two-sided contracts.”
- Lex drafts the contract from a description of the deal, usually one sentence.
- Both sides negotiate through one share link.
- Changes arrive as redlines, with Accept, Counter and Decline.
- Every version is kept. Nothing is edited silently.
- When the words are agreed, both sides e-sign one frozen version.
- Each side gets its own private Lex. The other side never sees those chats, notes or playbook.
- The other side never pays and never needs an account.
- Lex drafts and explains. It never sends, accepts or signs.
- Plain English explains each clause. The legal wording governs.
- Free £0, Plus £15/mo, Pro £29/mo, Team £119/mo for 5 seats, Enterprise from £750.
- Free and Plus may use de-identified content from your own side of the deal to improve Lex, with an opt-out in Settings. Pro, Team and Enterprise content is never used, and the other side's content is never used.
- Connectors for ChatGPT, Claude and Codex are coming soon. They are not available yet.

## Cláusulas

- [Indemnity](https://contracts.io/es/clauses/indemnity): An indemnity is a promise by one party to cover certain losses the other party suffers, usually losses caused by a third-party claim.
- [Force majeure](https://contracts.io/es/clauses/force-majeure): A force majeure clause pauses or excuses a party's obligations when events outside its control stop it performing.
- [Limitation of liability](https://contracts.io/es/clauses/limitation-of-liability): A limitation of liability clause caps how much one party can recover from the other and lists the kinds of loss that cannot be claimed.
- [Governing law and jurisdiction](https://contracts.io/es/clauses/governing-law-and-jurisdiction): A governing law and jurisdiction clause names which country's law applies to the contract and whose courts hear disputes.
- [Termination](https://contracts.io/es/clauses/termination): A termination clause sets out how and when either party can end the contract, and what happens when it ends.
- [Confidentiality](https://contracts.io/es/clauses/confidentiality): A confidentiality clause limits how each party can use and share the other's private information.
- [Intellectual property assignment](https://contracts.io/es/clauses/intellectual-property-assignment): An intellectual property assignment clause transfers ownership of the rights in the work from the creator to the client.
- [Payment terms](https://contracts.io/es/clauses/payment-terms): A payment terms clause sets how much is paid, when invoices are due, and what happens if payment is late.
- [Entire agreement](https://contracts.io/es/clauses/entire-agreement): An entire agreement clause says the signed contract is the whole deal and replaces earlier discussions and drafts.
- [Assignment and subcontracting](https://contracts.io/es/clauses/assignment-and-subcontracting): An assignment and subcontracting clause controls whether either party can hand the contract, or the work, to someone else.
- [Non-compete and restrictive covenants](https://contracts.io/es/clauses/non-compete-and-restrictive-covenants): A non-compete is a restrictive covenant: a promise not to do competing work for a time and in a market, and it only stands in England and Wales if reasonable.
- [Non-solicitation](https://contracts.io/es/clauses/non-solicitation): A non-solicitation clause is a promise not to poach the other side’s staff, customers or leads for a period after the job — narrower than a non-compete.
- [Warranties](https://contracts.io/es/clauses/warranties): A warranty is a promise that a fact is true, or that the work meets a stated standard — and a breach of it is claimed as ordinary damages, not as an indemnity.
- [Dispute resolution](https://contracts.io/es/clauses/dispute-resolution): A dispute-resolution clause says how a fight is handled: negotiation, mediation, then court or arbitration, and which forum hears a claim that cannot settle.
- [Data protection](https://contracts.io/es/clauses/data-protection): A data-protection clause records how personal data is handled; where one side is a UK GDPR processor, Article 28(3) requires named processor terms.
- [Late-payment interest](https://contracts.io/es/clauses/late-payment-interest): A late-payment interest clause sets what is added when a commercial invoice is late — and in the UK a statute already supplies a rate and fixed compensation.
- [Cancellation and kill fee](https://contracts.io/es/clauses/cancellation-and-kill-fee): A cancellation and kill-fee clause says what the client pays if it calls off a freelance or creative job for convenience, and who owns the unused work.
- [Notices](https://contracts.io/es/clauses/notices): A notices clause says how official messages under the contract are given — to whom, by which method, and when they are treated as received.
- [Auto-renewal](https://contracts.io/es/clauses/auto-renewal): An auto-renewal clause rolls a fixed term into a further term unless one side gives notice to stop it — so the notice window is the line that matters.
- [Change control](https://contracts.io/es/clauses/change-control): A change-control clause says how extra scope is requested, priced and signed — so a chat message does not quietly rewrite the job.
