Build a Video Thumbnail Maker with Claude Code

Build a Video Thumbnail Maker web app. People search for "video thumbnail maker" about 1,000 times a month, plus related searches like "extract video thumbnail", "video preview image", "thumbnail from video". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build a video thumbnail maker web app. Create a homepage with video upload and automatic frame extraction showing multiple thumbnail options. Add timeline scrubber for manual frame selection and basic editing tools (text overlay, filters, brightness). Include preset thumbnail sizes for different platforms (YouTube, Vimeo, social media). Show thumbnail previews with download options and batch processing for multiple videos. Use video-focused design with clear frame selection interface. Focus on video upload and frame extraction 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 VEED.io, Kapwing, Clideo do it and make ours simpler and faster.
3. Make it rank. Use "video thumbnail maker" 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: /extract-thumbnail-from-[video-format], /video-thumbnail-maker-[platform], /create-preview-for-[video-type].
4. Monetisation: Freemium: 5 thumbnails/day, $6/mo unlimited + HD quality. 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.
