Looking for a custom, fast, and lightweight AI web tool that solves one specific task perfectly?
Whether you need an AI copy generator, document summarizer, SEO prompt tool, or an interactive internal utility for your team, you don't need a bloated monthly subscription. You need a dedicated, autonomous AI web app that belongs 100% to you.
Using modern Vibe Coding workflows (Next.js, React & Tailwind CSS), I build production-ready single-purpose AI tools powered by your preferred LLM (OpenAI, Claude, or Gemini).

Smart Text Analyzers & Summarizers (meeting notes, reports, articles)
Prompt Engineering Interfaces (multi-field forms with tailored system prompts)
Micro-SaaS tools ready to launch on Product Hunt or embed on your website
Technical Highlights:
Fast, clean React / Next.js frontend with modern dark/light styling
Secure server-side API handling (your API keys remain completely hidden)

FAQ
How does the AI integration work?
The web app securely connects to OpenAI, Anthropic (Claude), or Google Gemini via their official APIs. The API key is stored safely on the server side in environment variables, so your users will never see your secret key.
What are the running costs for hosting and AI?
Hosting on Vercel is completely free for standard use. For the AI generation, you only pay a few cents per hundreds of requests directly to OpenAI or Google using your own pay-as-you-go API key (no monthly app subscriptions).
Can this tool be embedded into my existing website?
Yes. The application can run independently on its own custom domain or subdomain (e.g., tool.yoursite.com), or be embedded seamlessly into WordPress, Webflow, or Tilda via an iframe.
Do I own the code?
Yes, 100%. You receive the complete GitHub repository with well-structured Next.js code that you can freely modify or expand.
