writewithstela.comAbout Stela Writing Studio
Stela Writing Studio is a desktop workspace for manuscripts, novels, and screenplays with optional AI on your terms. Bring your own Gemini, OpenAI, or Anthropic API key, choose the selection, section, or document context, and review proposed edits before applying them. For external agents, Stela includes an opt-in local MCP server over HTTP and stdio. It can discover, search, read, create, and edit documents in approved workspaces. Access can be read-only or writable, paused, and revoked; writes use revision checks and pre-edit save points. Stela must be running; this is a bundled local server. Organize chapters and scenes, compile manuscripts, and export writing through DOCX, book PDF, Fountain, FDX, and PDF workflows. Available for Windows x64 and macOS on Intel and Apple Silicon. Free during beta; optional AI provider charges may apply.
