Ecosystem
Ecosystem🔗
The LocalGPT family, the open format at its center, and the broader landscape of AI assistant implementations and explorable world systems.
LocalGPT Apps🔗
Everything under localgpt.app runs locally and is open source (Apache 2.0), in one repository.
| What it does | |
|---|---|
| LocalGPT, the desktop app | One window, every mode: a world from a prompt, from a Markdown document or from a song, or any .world package opened as a live canvas that agents edit from outside |
| LocalGPT Gen | The world builder as a binary: interactive, an MCP server for Claude Desktop, Claude Code, Codex, Gemini CLI and editors, headless generation, collaborative sessions, the live canvas |
| Previs | Drop a screenplay on localgpt.md — a PDF, a Final Draft file, Fountain or Markdown — and get a board in the tab: a set, stand-ins and coverage per scene with real lenses, nothing installed, nothing uploaded. localgpt-previs is the same draft on the command line. Then revise the shots in the live canvas |
| The assistant | A local AI agent with persistent Markdown memory, heartbeat and cron, a kernel-enforced shell sandbox, an HTTP API, an MCP server — and localgpt world, a .world package’s command line |
| LocalGPT Verse | Listens to your music and imagines a living 3D world for every song — analyzed, staged and performed on your machine. A mode of the desktop app, and a window of its own |
| LocalGPT MD | Opens a Markdown file and walks through it as a 3D world; every section becomes a place, and saving rebuilds it. A mode of the desktop app, with an editor pane and in-place rebuilds, and a window of its own |
The sites: localgpt.app is the hub and the only docs site; gen.localgpt.app and verse.localgpt.app are landing pages; localgpt.md is the previs page (md.localgpt.app redirects there); localgpt.world is the gallery and the one web viewer, which opens worlds from every app in the browser; localgpt.rs is the devlog about building it all in Rust.
The Open World Format🔗
Every LocalGPT app reads and writes one format, and the format is not LocalGPT’s: the Open World Format is an open standard for .world packages — interactive, AI-authorable 3D worlds: the scene, the history that built it, and what happened in it. A package is a folder holding a world document, a typed state document, an append-only session log and content-addressed assets; the state at any revision is a pure fold of the log over the base. It sits above glTF, not beside it: meshes stay glTF, referenced by hash.
The specification repository holds the spec (draft 0.3), the normative JSON Schema, the conformance worlds, and five reference parse-and-fold packages — npm, PyPI, crates.io (openworldformat, which this workspace consumes), SwiftPM and Kotlin. Other tools over the format include worldprobe, a desktop inspector that folds, validates and walks a package’s history and branches, and worldwalk, a viewer for macOS, iOS, iPadOS, visionOS and Android that opens a package and walks the world it folds to, at any branch tip.
