Who shares confidential information?
I share confidential information
One-way. You are the Disclosing Party, the recipient is the Receiving Party.
They share confidential information
One-way. The recipient is the Disclosing Party, you are the Receiving Party.
We both share confidential information
Mutual. Each party is bound as Receiving Party for what the other shares.
Purpose What the information is shared for. The Receiving Party may only use it for this. Use of AI tools
No AI tools
Only services that keep nothing after answering. Few services meet this; use it for highly sensitive information.
AI tools that do not train on the information
Allowed on business or API terms that rule out training on the information and sharing it. Suits most teams that work with AI.
Any AI tool
Any service may be used, but whoever receives the information may not train a model on it.
Extra clauses
Non-solicitation and non-use
They can't use what you shared to compete, or approach your customers, suppliers or staff. Competing without it stays allowed.
Non-circumvent
They can't go around you to the contacts you introduced.
Penalty for a breach
A fixed sum they forfeit for each breach, set per clause and capped. Only where the law gives it effect, and never against a recipient who signs as a consumer.
Allow group companies
A receiving company may share the information inside its group. Off keeps it to the company you deal with.

This address sets the law that governs the NDA.

Recipient

A name and an email address. They fill in their own details when they sign.

Full name
Email address
I've read the Terms of Service and agree to follow them.

Send NDA is not a law firm and gives no legal advice. Where it matters, have a lawyer in your jurisdiction review the agreement.

How it works

Sixty seconds, both signatures.

You send, they sign, you countersign. Both of you get the same sealed PDF, and anyone can check it against the original later.

  1. Sent Emailed to both of you
  2. Viewed You see when they open it
  3. 3
    Signed They sign first
  4. 4
    Completed You countersign, both get the PDF
Your law, not ours
The agreement is governed by the law of the country you send from, narrowed to your state or part of the UK, and in a federation the federal law that applies there too.
One page of choices
One-way or mutual, how long it runs, and the clauses you want. The contract wording follows your answers.
Proof that holds its shape
Every step is written to a chained log. The final PDF is frozen once both of you have signed.
Check any copy
Upload a PDF or its signing certificate on the verify page and see whether it is the one both parties signed.
Mutual NDA | 2 years + 3 years confidential Governed by Dutch law

For agents

Send one from Claude.

Send NDA is an MCP server. Connect it once, and your assistant can send an NDA, fill in your details on the ones sent to you and sign them, amend or delete one until someone signs, resend the link and read the docs.

Add https://sendnda.com/mcp as a custom connector and sign in with your email address. Sending goes out straight away, so your assistant confirms the details with you first. Read how to connect.
