Build a Content Idea Generator with Claude Code

Build a Content Idea Generator web app. People search for "content idea generator" about 1,000 times a month, plus related searches like "blog post ideas generator", "social media content ideas", "content brainstorming tool". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build a content idea generator web app. Create a homepage with industry selector and content type options (Blog, Social Media, Video, Podcast). Add topic input field and trending keyword integration. When users generate, show 20+ content ideas with titles, descriptions, and content angles. Include content calendar integration and difficulty ratings. Add save/favorite functionality and export options (CSV, PDF). Show trending topics and seasonal content suggestions. Use creative design with inspiration-focused colors and clean typography. Focus on idea generation and organization first.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind). Write a short PLAN.md with the pages, components, any library or API you need, and what you are leaving for later. Then build.
2. Put the tool itself on the homepage so a visitor can use it within seconds, with no sign-up. Do the processing in the browser where you can, so it is fast and cheap to run. Look at how BuzzSumo, AnswerThePublic, ContentIdeator do it and make ours simpler and faster.
3. Make it rank. Use "content idea generator" in the title tag, H1 and meta description. Under the tool, add a short how-to and an FAQ with FAQPage schema, and add a sitemap and robots.txt. Scaffold these programmatic pages from one template and a data file: /content-ideas-for-[industry], /[platform]-content-generator, /content-brainstorm-[topic].
4. Monetisation: Freemium: 50 ideas/month, $8/mo unlimited + trend data. Add a pricing page and the free usage limit, and leave Stripe checkout as a clearly marked stub with the environment variables it needs.
5. Run it locally and test the main flow end to end, including edge cases like empty input and very large files. Fix what breaks, then finish with a summary of what works, what is stubbed and how to deploy it to Vercel.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.
