AI Captions & Caption Brief

capty doesn't write one caption and copy it everywhere. Every selected platform gets its own version – LinkedIn sounds different from TikTok, even behind the same image. You'll find this in Create, under "Generate Captions".

Generate with AI, or write yourself

Two buttons set the route:

  • Generate with AI – capty writes the suggestions. You can edit them freely afterwards.
  • Write yourself – you get empty fields and write your own. The platform tabs remain, so you can still give each channel its own text.

You can switch at any point: generate first, then rework by hand.

The caption brief – the biggest lever

The "Caption brief" field is optional but makes the largest difference. In one or two sentences, say what the post is about and what readers should do. The AI can see your image, but it doesn't know the occasion.

Weak: "New product" · Better: "Launch of our sustainable water bottle made from recycled stainless steel, in the shop from today, emphasis on durability rather than price."

What controls the tone

Just above, in "Tone, length & Brand Voice", you set how the writing works:

  • Tone: Inspirational, Professional, Casual & Fun, Witty–Ironic, Storytelling, Minimal.
  • Length: Short (1–2 lines), Medium, Long.
  • Call to action: None, Link in bio, Shop now, Sign up, Learn more, DM us.
  • Language: "Same as brand" takes the language from your Brand Voice; otherwise pick another.
  • Emojis: Auto, None, Few, Moderate, Lots.
  • Brand Voice, Target Audience, Things to avoid: pre-filled from your Brand Voice, changeable here for this post.
These settings only apply to the post you're working on. Permanent changes belong in the Brand Voice – otherwise you'll be setting them again every time.

Reworking the results

Every platform has its own tab. You can:

  • type straight into the field, trim it, add or remove hashtags,
  • regenerate a single version,
  • use "Regenerate all" to redo every version at once.

Regenerating overwrites the existing text. If you like a phrase, copy it out first.

When the suggestions don't fit

  • Too generic? The caption brief is too thin. Name the occasion, the audience and the concrete offer.
  • Wrong tone? Check the Brand Voice first – the per-post tone switch can't make up for a wrong baseline.
  • The same words every time? Add them under Words to Avoid in the Brand Voice.
  • Too long for TikTok? Set Length to Short and trim in that platform's tab.
  • No output at all? Check under Settings → Plan & Usage whether your AI generation allowance is used up.

Labelling AI content

Below the generate button, capty notes that AI-generated content may need to be labelled. Our free AI Label Check gives you a first read on your case. It isn't a substitute for legal advice.
