Wavegrain makes curated TikTok slideshows and Instagram carousels for your brand on autopilot. Add your brand from your website, save the photos you want to a board, and give Wavegrain a topic. It writes the hook, the slides and the caption in your brand's voice and designs every slide with your photos; an AI image fills a slide only if you choose Collection + AI. Edit any slide, save a slideshow as a format you can reuse, plan posts on a calendar, and let Wavegrain schedule and post them, or export a 1080x1920 ZIP or MP4 for TikTok and 4:5 or square sizes for Instagram. AI agents can use it through an MCP server.
