Turn every post into a conversion opportunity
The best social posts do not end at the caption. They drive people to the next step.
Mallary helps you add comments under posts automatically so every launch, update, video, or announcement can include the right CTA at the right moment. Add a signup link, trial link, demo link, product page, documentation link, community invite, or promo code directly under the post without making the caption feel crowded.
Then keep the conversation going with AI auto-replies that can help answer questions, point people to the right place, and support your social workflow after the post goes live.
- Put links and CTAs where people already look
- Add context without overloading the main caption
- Automate first comments and follow-up comments
- Combine comments, AI replies, and analytics in one platform
We are launching the new Agentic API for teams building social media workflows into their products.
Post once, publish everywhere, and add the right follow-up below it.
1/ Built for dashboard, API, MCP, and CLI publishing workflows.
2/ Add the CTA under the post without crowding the main caption.
Built for clean captions and better follow-through
Add useful follow-up without turning every caption into a wall of links.
Keep posts clean
Move links, hashtags, and extra context into the comments while keeping the main caption focused.
Drive the next action
Automatically add trial links, demo links, launch pages, docs, promo codes, or community invites under your post.
Automate the first comment
Stop manually pasting the same follow-up after every post. Add comments once and publish them with the content.
Use dashboard or API
Create comments from the Mallary dashboard or attach them programmatically through the API, MCP, or CLI.
Pair with AI replies
Seed the conversation with comments, then let AI auto-replies help answer questions and keep engagement moving.
How comments under post works
Comments are stored with the post request and published after the main post succeeds on supported platform and format combinations.
Write the post
Create the main caption, attach media, and choose the platforms you want to publish to.
Add follow-up comments
Add up to three comments for links, context, launch details, documentation, or offer copy.
Publish in one flow
Mallary posts the main update, then adds the supported follow-up comments under it automatically.

Add comments under posts without building another integration
