Yes, AI Can Build This: AI Social Media Caption Generator
Small businesses and creators describe a post once and get five platform-tuned caption variants in their saved brand voice, with ready hashtag sets and length checks.
The Prompt
Build an AI social media caption generator with these features: 1. Quick post builder: upload an image or video thumbnail (optional), describe the post in one line, and pick the platform: Instagram, TikTok, LinkedIn, X, or Facebook. 2. Platform-aware output: correct length and style per network, hashtag sets, and line breaks that match how each platform renders captions. 3. Voice settings: pick a brand voice from presets like playful, expert, luxury, or friendly local, or paste three sample captions and the AI matches that style automatically. 4. Generates five caption variants per run, each with a different hook type: question, bold claim, story, statistic, or call to action. 5. Emoji density slider from none to heavy, applied consistently. 6. Hashtag strategy section: five broad, ten niche, and three local or community tags, with a copy-all button. 7. Character counter with platform limit warnings before posting. 8. Saved brand voices, a favorites library, and export as plain text for the scheduler the user already has.
