“I stopped struggling with SEO the moment I fixed my prompts.”

Garry Vee — Fri, 20 Mar 2026 16:05:37 +0000

I spent hours trying to write “perfect SEO content.”

Watching tutorials.
Reading blogs.
Overthinking every keyword.

Still… nothing ranked.

Then I realized something simple:

It’s not about writing harder
It’s about prompting smarter

That’s when everything changed.

I built something I wish I had earlier:

An AI SEO Prompt Generator
that instantly gives you:

• Blog writing prompts
• Keyword research prompts
• On-page SEO prompts
• Ready-to-use ChatGPT instructions

No fluff. No guessing. No burnout.

Because honestly…

Most people don’t fail at SEO
because they’re bad at writing.

They fail because they don’t know
what to ask AI.

If you’ve ever:

stared at a blank screen
struggled to rank your content
wasted time tweaking prompts

This might help you.

Still improving it every day.

I built a free AI Prompt Generator for ChatGPT, Gemini & Claude

I built a free AI Prompt Generator for ChatGPT, Gemini & Claude

As developers and creators, we spend a lot of time trying to write the perfect AI prompt.

Whether you're using ChatGPT, Claude, or Midjourney, the quality of the prompt often determines the quality of the output.

But writing prompts from scratch every time can be slow and frustrating.

So I built a simple tool to solve that problem.

The Tool

I created a free AI Prompt Generator that helps you generate structured prompts instantly.

Try it here:
https://www.toolstackhub.in/tools/ai-prompt-generator

The goal was to build something simple, fast, and actually useful.

*No login, no API keys, no clutter.
*
Just enter your idea and get a prompt you can immediately use with AI tools.

Features

Generate prompts for ChatGPT
Generate prompts for Claude
Generate prompts for Midjourney
Simple and clean interface
Works instantly in the browser
Completely free

Why I Built It

I noticed that many prompt tools online are either:

• too complicated
• filled with ads
• require login

I wanted to create something minimal and developer-friendly.

The tool is part of a project I'm building called ToolStackHub, where I'm gradually launching useful browser-based tools.

Tech Stack

The tool was built using:

Next.js
Tailwind CSS
Static generation
Client-side processing

Everything runs directly in the browser, so it's fast and private.

Feedback Welcome

If you're a developer, creator, or someone who works with AI prompts, I'd love to hear your feedback.
