Build a Podcast Episode Title Generator with Claude Code

Build a Podcast Episode Title Generator web app. People search for "podcast episode title generator" about 150 times a month, plus related searches like "podcast title generator", "episode name generator", "podcast title ideas". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build a podcast episode title generator with topic input and genre selection. Generate multiple title variations with engagement scores and length optimization. Include trending keywords integration and title testing suggestions. Add save/favorite functionality and export options. Focus on getting title generation working 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 Copy.ai, Jasper, Writesonic do it and make ours simpler and faster.
3. Make it rank. Use "podcast episode title 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: /podcast-titles-[genre], /episode-names-[topic], /podcast-title-generator-[niche].
4. Monetisation: Freemium: 50 titles/month, $6/mo unlimited + trend analysis. 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.
