Keyword Insight — A Free, Open-Source SEO Suggest Tool

ad

Introduction

If you're running a blog or building a content strategy, the hardest part is often finding what people are actually searching for.
That's exactly what Keyword Insight was built for.

Keyword Insight is a lightweight, browser-based tool that fetches real-time search suggestions directly from Google and Bing. It reveals the keywords that everyday users are actively typing into search engines — giving you an honest, data-driven view of search demand before you write a single word.

No API key. No login. No subscription fee. Just open it and start discovering keywords.

What This Tool Does

🔍 Real-Time Suggest Extraction

Type any seed keyword and instantly retrieve the autocomplete suggestions that Google and Bing serve to users. These suggestions are powered by real search volume data and trending queries.

🌐 Multi-Engine Support

Switch between Google, Bing, or fetch from both at once to compare what each engine surfaces for the same topic.

🗂️ Bulk Extraction (50-Sound / Alphabet mode)

With one click, the tool automatically appends every Japanese mora (あ〜わ) or letter (A–Z) to your keyword and collects all variations — giving you a comprehensive keyword map in seconds.

📋 One-Click Copy

Export the full list of discovered keywords to your clipboard instantly, ready to paste into your spreadsheet, Notion doc, or SEO tool.

🔗 Check Top Search Results

Each keyword is clickable. Tap any suggestion and the top search results for that word open in a new tab — so you can analyze the competition on the spot.
