Platform-Specific AI Post Creators Frequently Asked Questions

Have questions about platform creators? Our support team is here to help.

What are Platform-Specific AI Post Creators?

Platform-Specific AI Post Creators are dedicated content creation tools designed specifically for LinkedIn, Instagram, X (Twitter), and Threads. Each creator provides AI-powered content generation with platform-specific features like customizable tones, character counting, hashtag suggestions, image generation, and—most importantly—real-time previews showing exactly how your post will appear on that platform's desktop and mobile interfaces before you publish.

Which platforms have dedicated post creators?

We currently offer dedicated post creators for LinkedIn (with professional and thought leadership tones), Instagram (with caption generation and visual grid preview), X/Twitter (with tweet and thread support, multiple tone options), and Threads (optimized for Meta's community engagement patterns). Each creator includes platform-specific AI models trained on what performs best for that network's unique audience and format requirements.

How do the real-time platform previews work?

Each post creator includes live preview panels that render your content using the actual design layouts from LinkedIn, Instagram, X, and Threads. As you type, add images, or generate content with AI, the preview updates instantly to show exactly how your post will appear on desktop, mobile, and tablet devices. This includes proper text wrapping, image positioning, hashtag highlighting, and even thread sequencing for multi-post content.

Can I create threads for Twitter/X and Threads?

Yes! Both the X Post Creator and Threads Post Creator include dedicated thread composition tools. You can create multi-tweet threads (up to 25 tweets on X), see real-time preview of the entire thread sequence, add images to specific tweets within the thread, and ensure consistent narrative flow. The AI can help you break long-form content into optimal thread segments with engaging hooks and strong conclusions.

What tone options are available for each platform?

Tone options vary by platform to match audience expectations: LinkedIn offers Professional, Thought Leadership, Storytelling, and Inspirational tones. Instagram provides Casual, Inspirational, Educational, and Behind-the-Scenes tones. X/Twitter includes Insight, Storytelling, Educational, Humor, and Hot Take tones. Threads focuses on Authentic, Community, Conversational, and Supportive tones. All tones can be further customized with your brand voice preferences.

Does it include image generation and search?

Absolutely! Each platform creator integrates AI image generation, web image search, and access to your media library. You can generate custom images from text prompts, search millions of stock photos, upload your own visuals, or pull from previously uploaded brand assets. The system automatically optimizes images for each platform's recommended dimensions and aspect ratios.

How does smart hashtag suggestion work?

Our AI analyzes your post content, industry, and target audience to suggest relevant hashtags that drive discovery and engagement on each platform. For Instagram, it recommends a mix of popular and niche hashtags (optimized for the 30-hashtag limit). For LinkedIn and X, it suggests professional or trending tags. You can accept all suggestions, pick individual tags, or add your own custom hashtags.

Can I schedule posts directly from the creators?

Yes! Once you're happy with your post preview, click "Schedule" to choose a specific date and time, or use Smart Schedule to automatically select the optimal posting time based on your audience activity. The post is added to your content calendar and will publish automatically. You can also save to drafts for later refinement or publish immediately if you prefer.
