Find subdomains with GPT, for free

SubGPT takes subdomains you have already discovered for a target and uses BingGPT to predict what other subdomains are likely to exists. It's free as it uses Microsoft Bing.

Like the tool? Support my work for as little as $1, here :)

Using SubGPT

Find Subdomains

subgpt -i input.txt -o output.txt -c /path/to/cookies.json

Generate Subdomains

If you just want to generate subdomains and not resolve them, use this option:

subgpt -i input.txt -o output.txt -c /path/to/cookies.json --dont-resolve

Important

1. Sometimes your cookie will expire if you visit bing.com. In that case, just export it again.
2. Make sure your subdomains list only has subdomains from one domain.
3. SubGPT looks at A/CNAME records to determine whether a subdomain exists. It can also detect wildcard on first-level subdomains and handle it automatically. You can go through the code to see how its implemented if it concerns you.
4. It can't replace traditional sub-generators like gotator, alterx, dnsgen etc. However, being powered by AI helps it generate subdomains that may not exist.
