Cross-posting from one composer
Write a post once and Postlia reformats it for each connected network, so users do not need to copy and rewrite the same update in separate apps.
Postlia
Freemium
Postlia is a social media scheduler and cross-posting tool for publishing one post across multiple platforms from a single composer. It also offers free AI content tools, analytics, and an MCP server for agents to draft, schedule, and verify posts.
What is Postlia?
Postlia is a social media publishing tool built around one composer, scheduled cross-posting, and a set of free content utilities. It lets users connect social accounts, write a post once, and publish or schedule it across supported networks such as LinkedIn, Bluesky, Instagram, TikTok, Pinterest, YouTube Shorts, and Mastodon.
The product also includes a library of 25+ free tools for tasks like handle checking, caption writing, hashtag generation, bio optimization, and content repurposing. For users building agent workflows, Postlia offers an MCP server and API access so AI clients can draft, schedule, and verify delivery.
What can Postlia do?
Scheduled publishing
Posts can be queued on a calendar and published at a chosen time, which supports batch planning and more deliberate timing.
Per-platform caption tailoring
The composer supports different captions for different networks, which is useful when the same idea needs a different length or tone by channel.
Multi-account posting on Pro
Pro users can connect multiple accounts on the same platform and choose exactly which accounts receive each post, which is useful for agencies and multi-brand workflows.
Analytics board
Postlia includes engagement and follower-growth analytics for connected accounts, along with guidance on when an audience tends to be active.
Free AI and utility tools
The site includes more than 25 free tools such as handle checkers, caption generators, hashtag tools, character counters, post previews, and thread splitters, with many available without signup.
Use Cases
“Solo creators managing several channels”
A creator can draft once, adjust captions per platform, and schedule a week of posts without switching between multiple tools.
“Founders and makers posting alongside other work”
Users who post occasionally can use the calendar, free AI tools, and repurposing tools to turn one update into several platform-specific versions.
“Agencies handling client accounts”
Pro's multiple accounts per platform, client review links, and grouped publishing fit workflows where one team posts for several brands or clients.
“Teams using AI assistants to publish content”
With the MCP server, an AI client can create drafts, schedule posts with media, and check delivery receipts after publishing.
“Users testing handles and content ideas”
The free tools section supports quick tasks such as checking usernames, generating bios, previewing posts, and finding hashtags before publishing.
