What is AI Social Media Post Generator?
Semrush's AI Social Media Post Generator (Social Content AI in the Semrush Social Toolkit) helps users ideate, create, design, and schedule social media posts, images, carousels, and short videos tailored to specific platforms and brand voice. The generator surfaces topic ideas from a website or business description, trend-based inspiration via Top News by Category, and converts ideas into ready-to-publish posts with adjustable tone, post type, and platform-specific formats — then sends finished content to Semrush's Social Poster for scheduling or publishing.
AI Social Media Post Generator pricing
Pricing model: Freemium
Semrush offers multiple entry points: the free AI Text Generator (part of the Content Toolkit) allows up to three free uses per day without registration for text generation; Social Content AI is included within Semrush’s Social Toolkit (paid access) and the AI Social Content Generator app in the Semrush App Center is offered as a paid subscription with tiered limits. The AI Social Content Generator app subscription is listed at $35/month and includes management for two brands, up to 200 AI-generated posts per month, 100 competitor analyses per month, and 50 minutes of voice-over per month; optional add-ons are available (for example, +$20/month for additional brand/posts/competitor analyses/voice minutes, and +$15/month for premium stock assets). Additional billing options inside the Semrush account allow purchasing extra brands, post credits, or competitor analyses a la carte.

Frequently asked questions about AI Social Media Post Generator
How do I generate social post ideas with the tool?
Launch Social Content AI and enter your website URL or a short business description; the tool uses that input to generate categorized content ideas and organized suggestions, or you can enter topics manually and click 'Find ideas' to get fresh suggestions instantly.
Which social networks are supported for post generation and publishing?
Social Content AI supports Facebook, Instagram, X, LinkedIn, Google Business Profile, and Pinterest for content generation and integrates with Social Poster to publish or schedule posts across those connected platforms.
Can the tool create images and videos as well as text?
Yes — you can add designs (static or video), generate images, create scripted short-form videos with AI narration, subtitles, and music, and edit creatives in the post editor before publishing.
How does the Top News by Category feed work?
Top News by Category updates regularly (hourly in the dashboard) and displays fresh articles by category; each news card shows headline, source, date, and includes a 'Generate' button to convert that news item into a tailored social post.
What branding controls are available?
The Brand & Social Accounts area lets you set brand colors, fonts, brand name, social handles, main hashtags, tonality, and upload logos (light/dark); these settings are applied in templates, palettes, and generated posts to maintain consistency.
How do I publish or schedule content created by AI?
From the Content Library, open a generated post, click 'Publish' to enter the publishing flow, select connected accounts, choose date/time (or ask AI to suggest), and send to Social Poster to publish immediately or schedule it in the Content Calendar.
What are the limits on generated posts and brands?
Limits depend on your subscription or app plan; for the AI Social Content Generator app, the base subscription at $35/month covers two brands and up to 200 generated posts per month, with add-ons available to increase brands and post quotas.
Can I create e-commerce posts directly from my product catalog?
Yes — after linking your ecommerce platform (Shopify, WooCommerce, Squarespace, or Wix) or uploading a product catalog CSV, you can generate e-commerce posts using products pulled from your store and choose formats, aspect ratios, and captions.
How does competitor analysis work in the app?
Competitor Analysis examines a single social profile at a time to surface content themes, top-performing posts, engagement metrics, hashtag usage, posting cadence, and other insights, and allows exporting reports or saving PDFs for review.
What editing capabilities exist for video voiceovers and scenes?
The Voiceover tab allows per-scene voice selection, mapping text elements to voiceover, applying a single speaker across all scenes, adjusting highlight color for spoken text, and disabling voiceover for individual frames when needed.
