Technical founders can build a working product and still struggle to explain who it helps, why it matters, and what to say when launching it. The inputs already exist—a website, a README, a deck, screenshots—but translating them into a coherent campaign takes time and marketing experience. Reef turns those inputs into a reviewable launch workflow. A founder adds a product website, public GitHub repository, description, or source files, then chooses a goal such as getting early users or collecting feedback. Muse synthesizes a product brief, suggests an audience, identifies product claims with source references, and writes distinct drafts for X and Threads, with optional LinkedIn content. The application validates the model’s output before saving it. Founders can inspect the brief, review the suggested evidence, edit drafts, preview each post, and approve a specific version. Editing removes the previous approval. Approved posts can open in X or Threads with the text prefilled; the founder reviews the platform composer and presses Post. Screenshots and uploaded media can be downloaded and attached manually. An optional owner-scoped Buffer integration supports API-based queue submission, but it is not required for the direct-compose workflow. Reef treats platform differences as product requirements. Hacker News is a human-written, manual submission task, not another generated post. Samples cannot be approved for publishing, and unavailable analytics are shown as unavailable. A light, animated ASCII sky gives the workspace a distinctive visual identity without obscuring the work.
