Captions & hooks

Write captions for a post

Write scroll-stopping hooks

Content ideas & planning

Build a one-week content calendar

Create a 7-day content calendar for [platform] for [brand/topic]. For each day give the format, a hook, and a short caption idea. Keep the mix varied so it doesn't feel repetitive.

Hashtags & repurposing

Turn a video into a caption + clips

Here's a transcript of my video: [paste transcript]. Suggest a caption, three short clip-worthy moments with timestamps, and a title.

Sound human, not like a brand robot

The fastest way to make social content fall flat is to let AI write in the generic, exclamation-heavy "brand voice" it defaults to. Fix that in the prompt: describe your actual voice (dry, warm, nerdy, blunt) and give an example post you like, so the model has something real to match. The other lever is the hook — the first line decides whether anyone reads the rest, so it's worth generating ten and picking one. Use AI to produce volume and options; use your own judgement to choose what actually sounds like you.

FAQ

How do I stop AI captions sounding generic?

Describe your voice specifically and paste one or two example posts you like. Asking for several options and picking the most natural one helps far more than taking the first result.

Are AI-suggested hashtags reliable?

Treat them as a starting list, not gospel. Models can suggest tags that are oversized, off-topic or out of date, so sanity-check a few on the platform before using them.
