Listwave

Launching a new SaaS or startup shouldn't mean copying and pasting the same text into dozens of different spreadsheets and directory forms. Meet Listwave—your personal launch cockpit. Listwave lets you fill out your launch kit just once. It automatically stores and maps your name, taglines, descriptions, and pricing to 26+ of the top startup directories and listing communities (like Product Hunt, Show HN, and BetaList). When you're ready to submit, Listwave provides pre-mapped copy optimized for each specific site’s field requirements. It features private, WebGPU-powered on-device AI to rewrite your copy on demand without needing API keys. Track your progress, prioritize outlets with a simple drag-and-drop interface, and fully customize your list to ditch the launch spreadsheets for good.
