Rewordly Web

Rewordly Web is the SaaS platform behind the Chrome extension: product marketing, auth, account dashboard, AI endpoints, usage metering, subscriptions, billing, and content SEO.

The extension needed a trustworthy web surface for login, plan management, and AI processing without shipping secrets in the client.

I designed and built the platform as creator and full-stack product developer.

End-to-end ownership of the web product and APIs, including auth, billing integrations, content, and deployment.

A browser extension alone cannot own account lifecycle, payments, SEO acquisition, or secure model access. The web platform had to carry product marketing and operational systems.

• Built marketing pages plus authenticated login, logout, and dashboard experiences.
• Implemented rewrite and grammar API routes backed by OpenAI.
• Added Supabase auth with email OTP and Google login.
• Modeled usage limits and free/Pro plan behavior.
• Integrated Dodo Payments checkout and webhook handling for billing.
• Shipped blog, legal pages, and SEO infrastructure (metadata/sitemap).
• Deployed and operate the app on Vercel.

• Next.js + TypeScript for both UI and API routes.
• Supabase for auth and account data.
• Server-side AI calls so keys never live in the extension.
• Webhook-driven billing updates for subscription state.

• Keeping extension sessions and web auth in sync.
• Metering usage cleanly across free and Pro tiers.
• Building payment and billing UX as a solo product developer.
• Balancing marketing, SEO content, and product dashboard in one codebase.

• A production SaaS surface at rewordly.store supporting the extension’s auth, AI, and monetization paths.
• Demonstrates full-stack product ownership beyond UI-only work.
