Use tool ↗About AutoRegex
AutoRegex takes a sentence like 'match valid email addresses' and returns a working regular expression, and can also translate an existing pattern back into English. It is a single-page, donation-supported utility — no plans, no paywall, just a text box aimed at developers and analysts who reach for regex rarely enough to forget the syntax. Because it is a side project (a tip jar and crypto address stand in for pricing), treat it as a convenience rather than infrastructure.

Pros & cons of AutoRegex
For occasional regex needs it removes the syntax tax in seconds and asks nothing in return. It is a hobby project with no visible author, changelog or uptime promise, and generated patterns still need testing before production use.
Pros
- Free with no paywall in the way
- Two-way translation: English to regex and regex back to English
- Zero-friction single-page interface
Cons
- Page renders only with JavaScript and names no author or company
- No stated model, changelog or support channel
- Output correctness is unverified — always test the pattern
Best for
- Developers who write regex a few times a year
- Analysts cleaning data who cannot recall lookahead syntax
- Explaining an inherited regex in plain English
Not for
- Production dependence — no SLA, API or maintainer contact
- Complex patterns needing dialect-specific features (PCRE vs RE2)
Watch out: On 15 October 2026 the page loaded but the conversion endpoint it calls returned an error, so the converter may not answer at all; and when it does, generated expressions can be subtly wrong — run them through a tester such as regex101.
