Frequently asked questions
Are the hashtags researched?
They are built from your topic keywords. They are not popularity or competition research.
Does it post for me?
No. You copy the caption and post it yourself.
Which platform should I choose?
The platform changes the opening line and framing. LinkedIn captions are framed more formally; X captions are kept short and shareable.
