Share your posts on LinkedIn with AI-optimized formatting.
Hot Metal lets you share your content on LinkedIn directly from the Publish modal. You can choose between two post formats, let AI optimize your text for LinkedIn best practices, and publish alongside your blog post in one step.
Prerequisites
Before you can share to LinkedIn, you need to connect your LinkedIn account. Go to Settings > Social Connections and follow the prompts to authorize Hot Metal. Once connected, the LinkedIn section in the Publish modal becomes active.
If your account is not connected, you will see a “Connect in Settings” note next to the LinkedIn option.
Enabling LinkedIn sharing
In the Publish modal, you will see the LinkedIn card below the Publications section. Click the card or check the checkbox to enable LinkedIn sharing. The card expands to show all the LinkedIn options.
Post types
Hot Metal supports two LinkedIn post formats. You can switch between them using the toggle buttons at the top of the LinkedIn section.
Link Post
A link post includes a short commentary text along with an article preview card that links back to your blog post. LinkedIn automatically generates the preview card from your blog URL, showing the title, image, and description.
The text field defaults to your draft’s hook — a short, compelling opening that encourages readers to click through. This works well for driving traffic to your blog.
Text Post
A text post publishes your full content as a standalone LinkedIn post. Hot Metal loads your entire draft body, strips out Markdown formatting (since LinkedIn only supports plain text), and adds a link to your blog post at the end.
Text posts tend to get more reach on LinkedIn because readers do not have to leave the platform. The text is automatically trimmed to fit within LinkedIn’s 3,000-character limit, cutting cleanly at paragraph boundaries.
AI optimization
For text posts, you can click the Optimize for LinkedIn button to have AI rewrite your content following LinkedIn best practices — short paragraphs, strong hooks, scannable formatting, and a conversational tone. The AI takes your current text and transforms it into something designed to perform well in the LinkedIn feed.
A loading indicator appears while the AI works. Once finished, the optimized text replaces the current content and an AI badge appears next to the label.
Character counter
For text posts, a character counter appears in the top-right corner of the text area showing your current count out of the 3,000-character maximum. If you exceed the limit, the counter turns red and you will need to shorten the text before publishing.
Link posts do not show a character counter since the commentary text for link posts is typically much shorter.
Editing before publish
You can freely edit the text in the text area at any time, whether it was auto-generated or AI-optimized. Your changes are preserved — Hot Metal will not overwrite text you have manually edited.
How publishing works
When you click Publish (or Update), your LinkedIn post is sent alongside your blog publish. LinkedIn sharing is fire-and-forget — the modal shows you the result of each destination after publishing. You will see a success message like “Shared on LinkedIn” in the confirmation banner, or an error message if something went wrong.
