Describe what you want to match in plain English ("US zip codes", "all URLs except localhost", "balanced parentheses up to depth 3") and get back a precise regex with a flavor-aware syntax (PCRE, JavaScript, Python re, Go regexp, POSIX), step-by-step explanation, and a test panel showing real strings that match vs. don't match.
Regex101 / Regexer / Debuggex ni nyenzo za kifahari - unaandika regex, zinaeleza. Free.ai ni mfanyakazi wa Gruder - unaelezea kile unachohitaji katika Kiingereza, inaandika regex.
PCRE (default in PHP, Perl, most modern Linux tools). JavaScript (browser + Node, no lookbehind in Safari ≤16.3). Python re (closest to PCRE, no possessive quantifiers). Go regexp (RE2 - no backreferences, no lookarounds, but linear-time guaranteed safe). POSIX BRE/ERE (grep, sed without -E). Pick the one your target language uses - features like lookbehind / possessive quantifiers / named groups don't port across all flavors.
Honest answer: no regex matches every real-world input perfectly. Email validation alone has a 6,425-character "RFC 5322 compliant" regex nobody actually uses. Free.ai targets the 99% case for the use you describe and warns about known edge cases in the explanation (e.g., "this matches example.co.uk but not example.museum"). Always test against real data before shipping to production.
Ndiyo huchanganya neno hilo la regex katika maelezo yaliyo kwenye sanduku la maelezo lililotiwa "cheo: " (e.g., مexlain: יהוה?*[A-Z])[5]?*\d).[5][5] na kigezo kitavunja kila ishara na kukuambia ni nini hasa kilicho sawa na hicho. Utumizi / alcode/exlain/slainc).
Ndiyo - wakati kiungo kilichochaguliwa kinapowategemeza. PCRE/Python/JS inaporuhusu mtazamo chanya na wa kiyozi; maelezo ya nyuma yanafanya kazi katika PCRE/Python/NGava lakini SI katika Go (RE2). Mfano huu huchagua jengo sahihi zaidi na kuonya wakati kitu fulani hakinaweza kubebeka.
When asked to match "letters" or "word characters" the model uses Unicode-aware classes (`\p{L}`, `\p{N}` in PCRE/Python/Java; `[\p{L}]` with the `u` flag in JavaScript) instead of legacy ASCII-only `[a-zA-Z]`. Mention "ASCII only" in the prompt if you want the legacy behavior.
Mfano huo umeagizwa kuepuka vipapasio vilivyojengwa kama faida za parafali kama vile faida ya+) ambayo hufanya ReDoS. Kwa maana Go (RE2) injini iwe na uhakika kwa ajili ya muda ambao hili haliwezekani kwa ujenzi. Kwa ajili ya PCRE/JS/Python, sikuzote chunguza kompyuta ndefu sana baada ya nta kuingia Regex101 kwa kamba 10,000 na kuangalia ngazi kinyume cha hilo.
ChatGPT (GPT-4) handles regex well but costs $20/mo and the context isn't regex-tuned. Free.ai's system prompt forces explicit flavor + match/non-match test cases + complexity warnings. Self-hosted Qwen 3 Coder is free under the daily token pool. For unusually weird patterns, premium GPT-5 is available with paid tokens.
Ndiyo - nta ni mchanganyiko wa ladha ya risasi na inauliza "kuunganisha kiungo hiki cha Python kwenda Go RE2".
Ndio - POST to /v1/chat/with mfumo maalumu wa uundaji wa kompyuta unaharakisha na ufafanuzi wako kama ujumbe wa mtumiaji.Faida kwa vifaa vinavyoendeshwa na magari na mtumiaji kwa kompyuta (hakuna namna ya wajenzi, watengeneza magogo).
Ndiyo - kipande cha msingi cha maandishi kina muundo kamili kwa kutumia lugha ya kawaida inayoitwa pimiters (5/tatani/flags mbingunis, na pia"pter" kwa Python, faida ya Go 178/ 171-1.
