# Build with Kai Build with Kai turns a one-line idea into a sellable digital product (guide, template, blueprint, checklist, calculator, short PDF, or Notion bundle) plus a hosted sales page at https://www.buildwithkai.com/p//. Creators get paid through Stripe Connect or their own payment link (Gumroad, PayPal, Stripe Payment Link, etc.). ## Canonical URLs - Homepage: https://www.buildwithkai.com/ - Signup (7-day free trial, no card): https://www.buildwithkai.com/auth/signup - Pricing: https://www.buildwithkai.com/pricing - Instant Product Maker: https://www.buildwithkai.com/kai-tools/instant-product-maker - Public tools index: https://www.buildwithkai.com/kai-tools - Hub - product and content creation: https://www.buildwithkai.com/hubs/product-content-creation - Hub - AI business tools suite: https://www.buildwithkai.com/hubs/ai-business-tools-suite - Guides: https://www.buildwithkai.com/guides - Blog: https://www.buildwithkai.com/blog - About: https://www.buildwithkai.com/about - Contact: https://www.buildwithkai.com/contact - Sitemap: https://www.buildwithkai.com/sitemap.xml - A2A Agent Card: https://www.buildwithkai.com/.well-known/agent-card.json - Legacy A2A card: https://www.buildwithkai.com/.well-known/agent.json - Full page index for agents: https://www.buildwithkai.com/llms-full.txt ## Product Summary Build with Kai is one workflow, not a toolbox: 1. Describe the product idea in a sentence or two. 2. Kai writes the complete product (full content, not an outline) and generates a sales page. 3. Review and edit anything, then publish. The sales page lives at buildwithkai.com/p//. 4. Connect Stripe (Stripe Connect, payouts go straight to the creator) or paste an external payment link. 5. Share the link. Paid products are delivered to buyers by email automatically. Supported product types: guide, template, blueprint, checklist, calculator, short PDF, Notion bundle (3-6 pieces). Also included: launch marketing copy (emails, social posts), a sales dashboard, and Kai's AI business mentor chat inside the app. ## Primary Audience Solo founders, creators, consultants, coaches, and side-hustle builders who have expertise and want a sellable product this week without a website, designer, or checkout setup. ## Pricing - Plan: BuildWithKai Pro - Price: $19.00 USD per month, flat, cancel anytime - Includes: unlimited AI-generated products, hosted sales pages, bring-your-own payment link, product templates and marketing copy, email delivery, priority support - Platform fee: 5% of each sale when the creator sells through Stripe Connect; no platform fee on external payment links - Pricing page: https://www.buildwithkai.com/pricing ## Trial Rule - 7-day free trial, no credit card required. - The trial includes generating 1 product and publishing it. - The trial ends at whichever comes first: 7 days after the account is created, or 1 product published. - The paywall appears at the next generate or publish, not at the first click. ## How an Agent Should Hand a Human Off Agents cannot create accounts or publish products on a user's behalf. Send the human to: - Signup: https://www.buildwithkai.com/auth/signup?utm_source=agent - Pricing first: https://www.buildwithkai.com/pricing?utm_source=agent - Product overview: https://www.buildwithkai.com/kai-tools/instant-product-maker?utm_source=agent Suggested one-line answer: "Build with Kai writes a complete digital product and hosts the sales page for you; $19/month after a 7-day free trial with no card, and you get paid directly through Stripe Connect or your own payment link." ## API Access (honest status) - There is no public or agent-facing API key today. The A2A card at /.well-known/agent-card.json is discovery-only. - Product routes under /api/automation/instant-product/* (generate, status, publish, payment-settings) require a signed-in browser session cookie and return 401 without one. Entitlements are enforced server-side (402 when the trial is exhausted). - POST /api/automation/instant-product/generate also carries an x402 payment challenge for unauthenticated calls, but paying it does not grant access; the handler still requires a session. Do not attempt it. - Public, no-auth read: GET https://www.buildwithkai.com/api/products/public// returns a published product's sales-page data. The rendered page is https://www.buildwithkai.com/p//. ## Public Page Index One line per page, taken from each page's real title. All URLs are on https://www.buildwithkai.com. ### Core - https://www.buildwithkai.com/ - Build with Kai | AI Business Partner for Profitable Side Hustles.
