Who generates regex with AI
- Devs
- Describe a pattern instead of crafting regex by hand
- A working regex plus an explanation of each part.
- Data wranglers
- Build patterns for log parsing or data cleaning
- A regex for the messy strings you're matching — with test cases.
- Learners
- Understand a regex someone else wrote
- A plain-language breakdown of what it matches.
How the AI regex generator works here
- 01
Describe what to match
Open @vustbot and describe the pattern ("email addresses", "dates like 2026-06-25", "the ID in this log line"). Paste sample strings if you have them.
- 02
Get regex + explanation
A working pattern with each token explained, plus matches against your samples.
- 03
Refine
"Also allow the +tag in emails", "make it case-insensitive" — iterate in the same chat.
Generate a regex free
Open @vustbot, describe the pattern (and paste samples), and get a tested regex — free tier, no card.
Regex, honestly
Give samples
Paste a few real strings (matching and non-matching) — @vustbot builds and checks the pattern against them, which beats describing it in words alone.
Flavor matters
Say your regex flavor (PCRE, JavaScript, Python re) so the output works in your environment.

Frequently asked questions
How does the AI regex generator work here?
Open @vustbot, describe the pattern ("email addresses", "the ID in this log line") and paste a few sample strings. The bot returns a working regex with each token explained and checked against your samples.
Why should I paste samples?
Real matching and non-matching strings let the bot build and verify the pattern, which is far more reliable than describing it in words alone.
Which regex flavor does it use?
Say your flavor — PCRE, JavaScript, Python re, Go — so the output works in your environment.
Can it explain an existing regex too?
Yes — paste a regex and it breaks down exactly what it matches in plain language.
Will the regex be safe from catastrophic backtracking?
Ask it to check — it can flag patterns prone to ReDoS (nested quantifiers on overlapping input) and suggest a safer, linear rewrite for untrusted input.
