Built for Instagram.
Not generic AI.
Every feature is calibrated to Instagram's algorithm, format, and audience behavior — not copy-pasted from a generic writing tool.
Reels Hooks That Stop the Scroll
Generate attention-grabbing opening lines optimized for Instagram Reels. The AI writes hooks using proven patterns: curiosity gaps, bold statements, and trend-aware phrasing that drives watch time.
Caption Formats for Every Post Type
From aesthetic minimalist captions to storytelling long-form, product launches to behind-the-scenes — the AI adapts to the format. Just describe your post and the tone you want.
Smart Hashtag Sets
Get 20–30 hashtags per post, intelligently mixed across high-volume, mid-tier, and niche tags. This maximizes discoverability across audiences of all sizes without shadowban risk.
Stories & Carousel Text
Generate swipe-through carousel text, Stories poll questions, Q&A prompts, and call-to-action slides. Covers the full Instagram content ecosystem.
From idea to ready-to-post
in under 30 seconds.
Describe your post
Tell the AI what your photo or Reel is about — your product, your story, your niche. Add your brand tone if you have one.
Select Instagram & your content type
Pick Instagram as your platform and choose from caption, Reel hook, Story text, carousel copy, or auto-detect.
Copy, customize, post
The AI generates your caption and hashtags instantly. Review, make any tweaks, and post directly from the app.
