A desktop app designed for the lifecycle of your ideas: capture thoughts, track your cognitive energy, and synthesize projects. Verdant features an ink-and-paper aesthetic and a local-first architecture — your data never leaves your machine. Use our BYOK (Bring Your Own Key) model to connect OpenAI or Anthropic at raw API cost, or hook up a local model for 100% private, air-gapped synthesis. Available for Mac, Windows, and Linux.
