This AI tool writes your emails, texts, and even your abuelita’s birthday card

Seán Goedecke doesn’t use ChatGPT to write essays or code. He uses it to do the boring stuff that eats up his afternoons: replying to emails, drafting texts to his sister, and even writing his abuelita’s birthday card in Spanish. He feeds it his old messages, his tone, his quirks — like how he always ends with "¡te quiero mucho!" — and now the AI writes like him.

It’s not magic. It’s muscle memory for machines. He trained it on 300 of his own messages. Now when he needs to tell his cousin the tamales are ready, the AI doesn’t just say "The tamales are ready." It says, "Oye primo, ya están listos los tamales, no te los comas todos, que yo también quiero mi parte."

He uses it for work emails, too. No more "Dear Sir/Madam." Just: "Hola, aquí te paso lo que pediste. Si necesitas más, dime y te lo mando en una hora."

The tool? Zero by Vercel. Free. No login. Just paste, press enter, and let it learn. No prompts. No prompts. No prompts. He says the best part? It doesn’t try to sound smart. It sounds like him.

Why this matters for us: When the machine learns to speak like your tío, your mamá, your primo — you stop fighting tech and start using it to breathe.
