SocialAgentAI social media post generator
One idea in, a post for every channel out: a hook-first Instagram caption, a short X post, a considered LinkedIn update — with images, carousels or video, ready to review and schedule.
Free plan · Bring your own AI key · Approval before anything publishes
From idea to posts in three steps
-
Start with an idea
Write a sentence, paste a link from your website, or let AI suggest a topic from your brand.
-
Generate a version per channel
Each connected platform gets its own caption, sized for its limits and written for its audience.
-
Review and schedule
Check the previews, approve, and publish now or at a scheduled time.
Every format your channels use
Text posts
For X, Threads, LinkedIn and Facebook. On Instagram and TikTok, text posts go out as a quote-card image.
Images
Brand-styled artwork generated with your OpenAI, Gemini or Grok key.
Carousels
Two to five slides, published as carousels or multi-image posts where a platform supports them.
Short video
On Pro: 15–30 second vertical videos for Reels, TikTok and native video posts.
Research-based posts
On Pro: drafts built from your website or RSS sources, with the sources shown at review.
Recurring drafts
Schedules that prepare posts 1–14 days ahead of each slot.
Common questions
Which platforms does it generate posts for?
Instagram, Threads, X, TikTok, LinkedIn Company Pages and Facebook Pages — and it can publish to all six.
Is the AI post generator free?
The Free plan includes 15 published posts a month and unlimited generations on your own AI key. AI usage is billed by your provider.
Does it write in my brand voice?
Yes. Every draft is written from your saved brand profile: audience, tone, topics and language.
What languages does it support?
You set a language per brand, and drafts are written in it. Quality depends on the AI model you connect; major languages work well.
