nintact

AI first-responder for your contact form. Point a form at one URL and you get: delivery that actually lands in the inbox, automatic classification of what came in, and a reply draft written for you. A human approves before anything is sent.

No SMTP credentials. No SPF/DKIM/DMARC records. No domain verification. Mail goes out over nintact's already-authenticated sending domain, with Reply-To pointing at your own address — so replies reach you without you ever touching DNS.

import { NintactForm } from "nintact/react";

export default function Contact() {
  return <NintactForm formId="YOUR_FORM_ID" />;
}

That's the whole integration. formId is public by design — it is safe in client code.

Get a form id

npx nintact init

Asks for your email, sends a 6-digit code, and creates the form. No browser, one prompt. It writes NINTACT_API_KEY and NEXT_PUBLIC_NINTACT_FORM_ID to .env.local, then prints a snippet for the framework it detected.

Already have a key? Set NINTACT_API_KEY and init runs unattended.

Without React

import { submit } from "nintact";

await submit("YOUR_FORM_ID", {
  name: "Jane Doe",
  email: "[email protected]",
  message: "I'd like a quote.",
});

Or skip the package entirely. One tag renders the whole form:

<script src="https://nintact.com/embed.js" data-nintact="YOUR_FORM_ID" async></script>

Already have a form? Point it at nintact and keep your own markup:

<form action="https://nintact.com/api/f/YOUR_FORM_ID" method="POST">
  <input name="name"><input name="email"><textarea name="message"></textarea>
  <button>Send</button>
</form>

Reading what came in

The management API needs an API key, so call it from your server only.

import { createClient } from "nintact";

const nintact = createClient({ apiKey: process.env.NINTACT_API_KEY! });

const { messages } = await nintact.messages.list({ status: "needs_review" });
const { draft } = await nintact.messages.get(messages[0].id);

// The AI wrote a draft. A human decides.
await nintact.drafts.approve(draft.id);

Every message is classified as estimate_request, question, sales, spam, or other. Spam gets no draft and no notification.

CLI

npx nintact init [--name "Contact form"] [--email [email protected]] [--json]
npx nintact messages [--json]

--json prints machine-readable output, for use from scripts and coding agents.

Errors

Every error carries a nextStep telling you how to recover.

try {
  await nintact.forms.create({ name: "Contact form" });
} catch (error) {
  if (error instanceof NintactError) {
    console.error(error.code, error.message, error.nextStep);
  }
}
