by TOOL3.COM – The Most Powerful Bulk Domain Name availability checker Online

Check Thousands of Domain Names at Once

Looking for a fast, accurate, and flexible way to check domain name availability in bulk? The Bulk Domain Availability Checker from TOOL3.COM lets you scan up to 20,000 domains instantly, or, if you are logged in, you can check hundreds of thousands by uploading a zipped file...

Whether you're generating domain suggestions by chatting with an AI chatbot, or pasting a list from your brainstorm, TOOL3.COM can extract all valid domains from any random text... and check their status in seconds.

🔍 How It Works

Paste any block of text—or upload a file—and our system will automatically extract valid domain names and check their status across hundreds of supported TLDs (except ccTLDs, which are coming soon).

Each domain is categorized into:
✅ Available
❌ Not Available
🕒 Pending Delete
🚨 Registry Redemption
⏳ Checking (Pending)

⚡ Lightning-Fast & Smart

Our smart system prioritizes active domains for faster results and handles inactive or expiring domains with accuracy. Enjoy a high-speed experience whether you're checking a few dozen names or uploading a file with thousands.

🧠 Ideal for AI-Generated Names

AI tools are great at suggesting domain ideas, but validating them manually is a pain. TOOL3.COM solves this. Just drop in your entire AI-generated list or output and we'll extract and check everything automatically.

Better yet, tool3 provides an AI domain generator that can do all of this automatically, but we understand that you may be looking to experiment with other LLMs online, if so, this tool is for you.
