Frequently asked questions
How long should an Instagram caption be?+
Only the first ~125 characters show before "...more", so that opening line is what actually earns attention — everything after it is for people who are already interested.
Should I copy a caption exactly as generated?+
Treat these as strong first drafts — swap in your own voice, specific details, and personality so it doesn't read as generic AI copy.
