If you work in SEO or digital marketing, you’ve probably faced this challenge — finding the right set of keywords for a topic. Sure, tools like SEMrush, Ahrefs, or Google Keyword Planner exist, but when you want bulk keyword ideas across multiple topics, it can turn into a long and boring process.
That’s what inspired me to build my own AI Keyword Generator Tool. It can generate search-based keywords for multiple topics at once, saving you hours of manual work. The best part? The results are realistic, based on what people actually search on Google.
Why I Built This Tool
When you ask ChatGPT or any general AI model for topic-based keywords, it often gives results that sound too formal or far from what users really type in search. People don’t search “comprehensive guide on SEO optimization practices” — they search “best SEO tips 2025.”
So, I decided to fix that.
I created a custom prompt process that refines results through multiple iterations, so the generated keywords actually sound natural and match real user behavior. Every topic you upload gets keyword variations that you can directly use to optimize your content, without extra filtering or guesswork.
How I Created It
I built this tool using Google AI Studio, which gives easy access to Gemini models and automation features. After testing and several versions, I achieved a flow that produces quality results, even for large sets of topics.

How to Use the AI Keyword Generator
Follow these quick steps to get your keyword list ready:
- Click the link above and open the app.
- Upload a CSV file with one column named “Topics” at the top. Each row should have one topic
- Click Generate Keywords after uploading.
- Wait for 2–3 minutes. The time may vary depending on how many topics your file has.
- Once done, you’ll get keyword lists for every topic in the file.
That’s it—download your ready-to-use SEO keyword list!
How It Handles Large Files
When generating keywords for hundreds of topics, API limits can be a big issue. Many tools fail if they process large data sets due to timeouts or rate limits.
To solve that, I designed this tool to process data in batches. So even if your file is big, it won’t break mid-way. It keeps working behind the scenes until the results are ready for you.

Final Words
This AI Keyword Generator Tool is built for real marketers who want accuracy without spending hours in manual keyword research. Upload your topic list, click once, and let the tool handle the rest.
If you’re working on blogs, YouTube titles, or even ad campaigns — this can be your new favorite shortcut for keyword discovery.
