Find and invent nicknames from your name, diminutives, reduplications (Fefê, Dudu), syllable blends, compound names and international styles.
Real nicknames rarely follow a single formula: some come from diminutive suffixes (-inho/-inha in Portuguese), others truncate the front of the name (apocope, like Rodrigo → Rod) or the back (aphaeresis, like Fernando → Nando), and Brazilian compound first names, increasingly the norm, generate their own blends, like Maria Luiza → Malu or Maria Eduarda → Duda. This tool combines a curated dictionary of nicknames genuinely used in Brazil and in English with a rule-based engine that recognizes syllable boundaries, applies the correct gender-matched suffix, and derives plausible forms even for rare, invented or foreign names, the dictionary guarantees accuracy for known names, and the rule engine guarantees the tool is never left with nothing to say. Turn on the international styles to see affectionate suffixes like -chan and -kun (Japanese fandom culture) and -ito/-ita (Latin style), and keep an eye on the fun-fact panel: sometimes the name you typed happens to match the real name of someone publicly known by a different nickname, like Xuxa (Maria da Graça) or Lula (Luiz Inácio).
The tool always checks the curated dictionaries (Portuguese and English) first, that's where the 'classic' nicknames live, genuinely documented and used (Francisco → Chico, Robert → Bob). But the dictionary is never the only source: the apocope, aphaeresis, diminutive and augmentative rules run for every name, whether or not it's in a dictionary.
That means a rare, foreign or even invented name always gets plausible suggestions, the engine looks for syllable boundaries (where a consonant is followed by a vowel) to cut the name naturally, instead of truncating at an arbitrary position.
Compound first names are now the most common pattern among newborns in Brazil, and many already have an established blend: Maria Eduarda becomes Duda, Maria Luiza becomes Malu, João Pedro becomes Jampa. The tool recognizes these pairs in its compound-name dictionary and suggests the real blend.
When the pair isn't in the dictionary, the engine still tries an algorithmic blend by joining the first two letters of each name (Maria + Júlia → Maju) and applies the apocope/aphaeresis rules to the second half of the name, the same logic behind Maria Eduarda → Duda, just without relying on a curated entry.
Many of the cutest Brazilian nicknames come from no suffix at all, they come from reduplication, repeating a syllable of the name: Felipe becomes Fefê, Eduardo becomes Dudu, Júlia becomes Juju, Beatriz becomes Bebê. The tool builds a syllable map of the name and reproduces that pattern for any name, with the right accent, not only for names already in the dictionary.
Beyond reduplication, the engine 'invents' nicknames by blending pieces of the first name and surname (Maria Fernanda → Mafer) and coining affectionate monosyllables (Fernanda → Fê). Every invented form passes a phonotactic filter that keeps it sounding like a pronounceable name, never a pile of scrambled letters.
Turn on 'Include international styles' to pick which base nickname the style applies to and see the same name rendered across eight cultures: Japanese (-chan, -kun, -sama, -senpai), Spanish (-ito, -illo), Italian (-ino, -uccio), Russian (-ka, -ochka), French (-ette, -ou), German (-chen, -lein), Korean (vocative particle) and internet (lil, -ster, -zilla). They're affectionate, fun styles, not literal grammar rules.
The fun-fact panel stays purely informational: it shows when the name you typed matches the real name of a publicly known person who goes by a different nickname, a fun coincidence, not a prediction.

It uses a hybrid engine: it first checks curated dictionaries of real, documented nicknames in Portuguese and English, then applies linguistic rules for truncation (apocope and aphaeresis), diminutives, augmentatives and compound names, which work even for names that aren't in any dictionary.
