Caption Writer warns you if a post runs outside the length range for its platform.

For each generated post you can:

• Copy to clipboard with one click
• Add company-specific details, links, or tags
• Adjust tone or length manually

Save: Save your posts to keep them in your Content Library. Unsaved drafts can be resumed from Home.

Platform best practices

LinkedIn

• Start with a hook (first 2 lines appear above "see more")
• Short paragraphs (2–3 lines each)
• End with a question or call-to-action
• Best times: Tuesday–Thursday, 7–8 am, 12 pm, 5–6 pm

X (Twitter)

• Hook in the very first line
• Specific numbers beat vague claims ("Save 5 hours/week" > "Save time")
• Best times: Monday–Friday, 9 am, 12 pm, 3 pm, 6 pm

Instagram

• Lead with a strong first sentence (it's all users see before tapping "more")
• Tell a story — Instagram rewards engagement
• 10–15 relevant hashtags grouped at the end
• Best times: Monday, Wednesday, Friday around 11 am–2 pm

Facebook

• Longer-form content performs well — ask questions
• Conversational tone resonates
• Best times: Wednesday–Friday, 9 am, 1 pm

Advanced tips

Tip 1: Batch-create a week of content Generate 5–7 posts per session, each for a different topic or angle. Schedule them with Buffer, Hootsuite, or Later.

Tip 2: Repurpose other content Turn a blog post into social posts, or convert an interview transcript into pull-quotes.

Tip 3: Create a recurring series

• "Monday Motivation" (Instagram)
• "Tip Tuesday" (LinkedIn)
• "Behind the Scenes" Friday (Facebook)

Tip 4: Pair with visuals Generate matching images with the AI Image Studio or branded graphics with the Social Image Creator.

Tip 5: Upload brand guidelines Add your style docs to the Brand Library and toggle Brand Guidelines on for on-brand output every time.

Common mistakes

❌ Same content copy-pasted to every platform ✅ Generate platform-specific versions with the right length and tone

❌ Too promotional — constant selling ✅ Follow the 80/20 rule: 80% value, 20% promotion

❌ Inconsistent posting schedule ✅ Batch-create and schedule a week or month at a time

❌ No call-to-action ✅ Ask a question, encourage shares, or prompt a reply

Troubleshooting

Content doesn't sound like your brand?

• Select a Persona before generating
• Toggle on Brand Guidelines (Creator, Pro, and Team)
• Upload brand documents to the Brand Library

Hashtags not relevant?

• Edit the generated hashtags manually
• Research platform-specific tags

Need a longer thread for X?

• Generate a single tweet, then use AI Refine to expand it into a multi-part thread.

Character limit exceeded?

• Switch to the "Short" length preference for that platform
• Use AI Refine and ask: "Make this shorter"

Credit cost

Each post costs 1 credit, so selecting three platforms costs 3 credits.

Next steps

• Generate matching images or social photos for your posts
• Create a deeper blog post on the same topic
• Send highlights as an email newsletter
• Turn your best posts into video scripts
