Write better content, faster
Vision-powered captions
Upload images or videos. The AI sees what's in them and writes captions that match the content, your brand, and your audience.
Platform-optimized output
Each platform gets its own caption. Instagram gets storytelling, LinkedIn gets professional tone, X stays under 280 characters.
7 text refinement tools
Fix grammar, make concise, expand, rephrase, improve structure, simplify, or polish. Select text and pick an option.
6 writing tones
Default, friendly, funny, bold, professional, and motivational. Each tone changes the style, not just a few words.
AI image generation
7 models from fast to photorealistic. Generate images in 5 aspect ratios and use them directly in your posts.
Video and audio analysis
Videos are analyzed frame by frame. Audio is transcribed automatically. Both feed into caption generation for accurate results.

AI caption generator that sees your content
Most AI caption tools ask you to describe what you want to write about. PostPlanify is different. Upload your images or videos and the AI analyzes them directly. It sees the product, the setting, the mood, and writes captions based on what's actually in the content. Combined with your brand description and target audience, it produces captions that are relevant and on-brand without you having to explain the context.
Platform-specific captions in one click
A caption that works on Instagram won't work on LinkedIn or X. Each platform has different character limits, audience expectations, and content styles. PostPlanify generates a separate caption for each platform you select. Instagram gets visual storytelling with line breaks. LinkedIn gets professional, insight-driven copy. X stays concise and punchy under 280 characters. TikTok gets trendy and informal. You get all of them from one generation.
Refine any caption with 7 AI tools
Generated captions aren't always perfect on the first try. Instead of rewriting from scratch, select any text in your caption and pick from 7 refinement options: fix grammar without changing your voice, make it more concise, expand with more detail, rephrase with different words, improve the structure and readability, simplify complex language, or polish with minimal subtle tweaks. Each option preserves your original tone and personality.
AI image generation for social media
Create images directly inside PostPlanify with 7 AI models. Flux Schnell for fast drafts, Flux Pro for balanced quality, Google Imagen for photorealistic results, Ideogram for text and logos, and Recraft for design work. Choose from 5 aspect ratios including square, portrait, and landscape. Generated images can be used in your posts immediately.
Built for speed and volume
PostPlanify supports bulk caption generation. If you have 10 posts ready to go, generate captions for all of them in parallel. Each post gets captions tailored to its specific images and target platforms. Video processing happens in your browser so your files stay private. Audio transcription runs automatically. The whole workflow is designed to help you batch content without slowing down.
