Aarunya AI Regex Generator vs Regex101
Both tools help you work with regular expressions — but they approach it differently. Here's when to use each.
Use Aarunya when…
You need to write a new regex fast and don't want to memorize syntax. Describe what you want, get a working pattern in seconds.
Use Regex101 when…
You already have a regex and need to debug it step-by-step, visualize match groups, or test it against many example strings.

The verdict
Regex101 is the industry standard for regex debugging — its match explorer and step-through debugger are unmatched. If you're debugging a 50-character pattern, Regex101 is the right tool.
Aarunya's AI Regex Generator fills the other half: generating patterns from scratch. Most developers spend more time trying to writea regex than debugging one. Describing "match all environment variable keys that start with NEXT_PUBLIC_" in plain English is faster than building it character-by-character.
FAQ
Is Aarunya Regex Generator better than Regex101?
They solve different problems. Aarunya is better when you need to create a new pattern from a plain-English description. Regex101 is better when you already have a pattern and need to debug, visualize, or test it.
Does Aarunya Regex Generator store my patterns?
No. Only your plain-English description prompt is sent to the AI (via OpenRouter). Your pattern, test strings, and any match results stay in your browser and are never stored.
Can I use both?
Yes, and many developers do. Generate the initial pattern with Aarunya, then copy it to Regex101 to test it against edge cases and visualize group captures.
