Author captions are different — readers expect a writer's hand in the copy. Generic AI fails here.
instacaptions AI writes captions for launches, pre-orders, signing tours, excerpt posts and review reposts — in the writer's voice.
What to post — with examples
Pre-order
Soft ask.
"Pre-orders open. Every one tells the algorithm a reader is waiting."
Excerpt
Let the prose carry.
"From chapter 3. Save it for the kind of evening that asks for nothing."
Review repost
Quiet, grateful.
"When a stranger writes the line that you wished the back-cover copy had said."
