What you set, and what it changes
Instagram Caption Generator is driven by tone (playful, warm, inspirational, minimal, funny, informative) and hashtags (no hashtags, 5 hashtags, 10 hashtags, 30 hashtags). Those are not decoration — each one rewrites the instruction the model is given, so changing tone and running again gives you a genuinely different piece rather than the same one reworded.
Hitting the length
Targets here run 90–320 words. A result that stops well short is usually not the model giving up, it is the request running out of token budget — so this page sizes that budget from your target rather than leaving it at a fixed default. The result panel shows the words produced against the words asked for, and if it still lands short, Continue extends the draft instead of rerolling it and losing what was good.
What happens to your text
Your settings are remembered in this browser so you are not retyping them next visit. The text itself is not: it is sent to generate the result and kept nowhere. Everything a model writes is worth reading before you use it — check any fact, figure, name or citation against a real source first.
