one post, 13 platforms, zero copy-paste
Most tools let you post to multiple platforms. PostAI adapts your content for each one — so every post feels native, not like a copy-paste job.
what you get
13 platforms connected
X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Telegram, Reddit, and Discord — all from one queue.
Per-platform caption variation
PostAI automatically rewrites each caption for its destination — shorter for Twitter, more formal for LinkedIn, hashtag-heavy for Instagram.
Format adaptation
Images are cropped to the right aspect ratio. Videos are trimmed to platform limits. Carousels become single images where carousels aren't supported.
Platform-specific features
First comment on Instagram, article link on LinkedIn, alt text everywhere — PostAI fills in the platform-specific fields automatically.

frequently asked questions
Can I post to multiple social media platforms at once?
Yes. PostAI publishes to all 13 connected platforms simultaneously from a single post. You write once; PostAI distributes everywhere, with per-platform captions.
Does cross-platform posting hurt engagement on individual platforms?
Only if you cross-post verbatim without adapting the content. PostAI automatically rewrites captions for each platform's context — shorter for Twitter, more formal for LinkedIn, hashtag-heavy for Instagram — so every post feels native rather than copy-pasted.
What platforms does PostAI support for cross-platform posting?
PostAI supports 13 platforms: X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Telegram, Reddit, and Discord. OAuth platforms publish through their official APIs; Bluesky uses an app password, Mastodon an access token, Telegram a bot token, and Discord a webhook.
