Build a Voice Cloning Tool with Claude Code

Build a Voice Cloning Tool web app. People search for "voice cloning tool" about 90 times a month, plus related searches like "ai voice cloning", "voice cloning software", "voice synthesis tool". The goal is a tool that ranks for those searches and makes money.

What it should do:
Create a voice cloning tool with audio upload and voice training interface. Include voice quality analysis, training progress tracking, and sample generation. Add voice customization controls and export options. Include ethical use guidelines and consent verification. Focus on getting basic voice cloning 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 ElevenLabs, Murf, Resemble AI do it and make ours simpler and faster.
3. Make it rank. Use "voice cloning tool" 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: /voice-cloning-[use-case], /ai-voice-[application], /voice-synthesis-[industry].
4. Monetisation: Freemium: 1 voice clone, $25/mo multiple voices + commercial use. 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.
