This panel has nothing to do yet.
Put some text into 01 and it lands here. The sample works too, if you would rather not think of anything.
How your text is processed. Pressing Write headlines sends your text to NexKit's servers and on to a third-party AI provider to generate the output. NexKit does not store prompts or output after the request, and never links them to an account, because there are no accounts — that is not a guarantee about what happens on the provider's side, so avoid pasting confidential, sensitive or personal information. AI-generated output can be wrong; check anything that matters before you rely on it.

What people use it for
- Get five subject lines to pick between instead of agonising over one
- Retitle a post that nobody clicked

- Write for a phone inbox, where forty characters is all you get
Questions
Why five and not one?
Because headlines are chosen, not generated. One suggestion invites you to accept or reject it; five let you see the range and notice which angle actually fits. Each tab shows its character count so you can rule out the ones that will be cut off.
Will it exaggerate to get a click?
It is instructed not to: every headline has to be supported by the text you gave it, with no invented numbers and no promises the piece does not keep. A headline that oversells is one the reader resents by the second paragraph.
How long should a subject line be?
Shorter than you think. Most phone clients show around 40 characters and most desktop clients around 60. The Short setting targets 50, which survives both. For blog titles, search results cut around 60 characters.
