AI that learns your voice
posterly's AI isn't generic — it adapts to your brand. The more you use it, the better it understands your tone, topics, and audience. Here's how to get the most from each AI feature.
AI Captions
Available directly in the composer, AI Captions generates platform-optimized copy in seconds.
How to use it:
- Open the composer and select your platforms
- Add your media or write a brief description of your post topic
- Click AI Caption to generate suggestions
- Choose a variation or edit to make it yours
Pro tips:
- The more context you give (topic, goal, audience), the better the output
- Generate multiple variations and mix the best parts
- Always review and add your personal touch — AI is a starting point, not the final product
- Your brand voice settings directly influence the output
AI Scheduler
The AI Scheduler is your conversational assistant for content planning. Access it from the sidebar.
What you can ask:
- "Write a caption about our new product launch for LinkedIn and Instagram"
- "When's the next available time to post?"
- "Schedule a post for @myaccount about our weekend sale"
- "Start a campaign for Black Friday across all my accounts"
It handles:
- Finding available time slots across your calendar
- Generating captions with your brand voice
- Scheduling posts directly from the chat
- Planning multi-post campaigns

Use cases:

- Product mockups and lifestyle imagery
YouTube Thumbnails — posterly includes specialized presets for thumbnails: bold text overlays, attention-grabbing styles, and formats optimized for click-through rates.
Brand Voice Learning
Your brand voice profile isn't static. As you write and edit captions, posterly's AI learns your preferences:
- Tone patterns — Whether you're casual or formal, humorous or serious
- Common phrases — Your go-to expressions and hashtags
- Topic focus — The themes you consistently post about
- Format preferences — Short punchy posts vs. long-form storytelling
Keep your brand voice settings updated as your brand evolves. Head to Settings → Brand Voice to refine it anytime.
