Write 5 birthday messages for [NAME].

Relationship: [FRIEND / PARENT / COLLEAGUE / PARTNER]
Age: [AGE]
Something we share: [MEMORY OR INSIDE JOKE]
Tone: [FUNNY / SWEET / FORMAL]

Vary the length: one tweet-sized, one WhatsApp message, one card verse, one long letter opening and one funny roast-style line. Sound like a real person, not a greeting card.

What you will get

Five birthday messages for one person in five lengths: a tweet-sized line, a WhatsApp message, a card verse, the opening of a long letter and a funny roast-style line, all in the tone you picked.

Common mistake

The roast line is too sharp for the audience, especially in a group chat.

Fix: Add “the roast must tease only a harmless habit, never age, looks, money or relationships”, and read it as the birthday person would.

Also watch for

All five start with “Happy birthday to someone who…”. Say “each message must start differently, and not with the words Happy birthday”.
With no memory given, the AI invents an inside joke. Give one real memory. If you have none, add “do not invent shared memories, keep it warm and general”.

Try a variation: voice note

Ask for “the long letter as a 30-second voice note script, with short sentences and a pause marked where I should smile”. A voice note feels more personal than text.

Still not right? Reply with this

Start each message differently, use only the memory I gave, keep the roast line to a harmless habit and make the WhatsApp one sound like a text from me.
