A data-driven research and scriptwriting platform for short-form video creators. Build a Watchlist of channels in your niche, deep-analyze their best-performing videos (1 credit each) to extract transcript, hook, storytelling format, visual layout, and outlier score, then turn those patterns into ideas and scripts. MCP is built in: connect https://mcp.sandcastles.ai/ to Claude Desktop or Google Antigravity, and ask it to bulk-analyze top outliers or research winning hooks and formats directly from the chat. Automations (Pro+) let rules auto-analyze videos by outlier score, views, and engagement. Pricing: a one-time $5/month Starter plan exists for new accounts only, but it is severely limited—10 credits/month, 1 workspace, no MCP, no Automations, no Reports, no new-channel tracking. Full plans: Pro $49/mo (or $39/mo annual, 100 credits, 3 workspaces, MCP), Visionary $99/mo (or $79/mo annual, 250 credits, 5 workspaces), Titan $499/mo (or $399/mo annual, 1,500 credits, 20 workspaces, API access). Note: Starter is a one-time offer and its limitations are easy to miss—full plans start at $49/mo. ScamAdviser shows a trust score of 0 but concludes the site is legit (score likely stale—not scanned in 30+ days); WHOIS is hidden and traffic is low. Not a publishing tool—research and scriptwriting only. Not to be confused with the open-source sandcastle-ai workflow engine on PyPI.
