Lightbulb is the AI social media post writer that turns your notes into platform-perfect content. Capture a thought, get publish-ready posts for X, Instagram, LinkedIn, Threads, Facebook, WhatsApp, and Line in seconds. Unlike a notes app that just stores ideas, Lightbulb distributes them. Unlike a generic AI copywriter, we know the difference between a viral X thread and a professional LinkedIn post. Your voice, every platform, no rewriting. HOW IT WORKS Log a note or idea. Lightbulb's AI scans your social media accounts to learn your niche, analyse your tone per platform, and continuously feed you viral content ideas based on what's trending in your space. Review, refine, and publish. AI NOTES TO POSTS Lightbulb is the AI note taker built for distribution, not storage. Every note is raw material for ready-to-publish content across all your active channels. PLATFORM-PERFECT CONTENT X and Threads: Viral tweets, full thread stories, hashtag optimisation Instagram: Captions, carousel slides, Stories copy LinkedIn: Professional posts, thought-leadership content Facebook: Group posts, Page updates AI GHOSTWRITER, YOUR VOICE, EVERY PLATFORM Lightbulb scans your recent posts to build a voice profile per platform, identifies your niche, and keeps feeding you a continuous stream of viral ideas tailored to your audience.
