Why does it ask who sent it?
Because the same words mean different things from different people. “k” from your partner mid-argument is not “k” from a coworker confirming a time. Picking who sent it, a friend, a match, a partner, a parent, a boss, gives the decoder the context you have in your head.
Does it just tell me what I want to hear?
No. It gives the likely readings in order and is honest when the most likely one is not the fun one. It also says when a message is genuinely ambiguous, which is often the most useful answer: stop decoding, ask them.
Decode, Is this flirting? or Vibe check?
Decode a message is for a single text whose meaning you are unsure of. Is this flirting? answers one specific question with a verdict. Vibe check reads the mood of a whole conversation. Red or Green Flag judges behaviour across messages. They all accept screenshots.
Then what?
Once you know what they meant, Reply to a text drafts the answer and Rate my message checks your draft before you send it. Decode a message runs in the TextAI app; share a screenshot or paste the text.
