relayFree Instagram caption generator
Describe what your post shows and what you want people to do. The AI suggests three different captions you can copy as they are or tweak.
What makes a good caption
Instagram cuts captions after about two lines, so the first sentence has to make people want more. Then give the useful details (price, date, place), then say clearly what to do next: order, book, comment, share.
- A first line that hooks, without shouting in capitals
- The detail people look for: price, size, date, address
- One clear call to action
- Three to eight relevant hashtags rather than thirty generic ones
Going further
This generator writes one caption at a time. In Relay, the assistant knows your brand, creates the visual, schedules the post and shows it to you before it goes out.
