A customizable AI workspace that adapts to how you work — start with deep code intelligence, then shape it with the plugins, tools, and integrations you need. One assistant. Endless possibilities.
macOS Apple Silicon · Windows x64 · Linux x64 — all builds below
No Docker, no cloud accounts, no API keys required to get running.
Available on macOS, Windows, and Linux.
Open Settings → License, paste your preview key, and click Activate. Don't have a key yet? Request one below — it's free for 30 days.
Go to Settings → AI Providers. Add Anthropic, OpenAI, or point it at a local Ollama instance. JMart Studio works with any OpenAI-compatible endpoint.
Open a folder, start a chat, or launch the MCP server so Claude Code and Cursor can use your project context directly.
Built for developers who want AI as a native part of their workflow — not a browser tab.
Runs models fully on-device via Ollama, or connects to Anthropic and OpenAI. Your code never leaves your machine unless you explicitly choose a cloud model.
Exposes a local MCP endpoint on port 3456. Claude Code, Cursor, and any MCP-compatible agent can use your project's live context — file tree, symbols, git state, terminal.
Semantic file indexing, symbol inspection, and codebase search — all local, all fast. The AI always knows what's in your project without uploading it anywhere.
Built-in Whisper STT for voice-to-text in chat. Speak your prompts, review them, send. Works fully offline using the local Whisper model.
Run agent tasks inside an isolated container. Supports Docker and Apple Container — the AI can write and execute code without touching your host system.
Store API keys and credentials in the macOS Keychain — never in plaintext, never in .env files. Access them from your agents without exposing them in prompts.
Track tasks, agent runs, and project work in a built-in kanban board. Agents can create and move cards. Everything stays local in SQLite.
Works with Anthropic Claude, OpenAI GPT, Ollama local models, or any OpenAI-compatible API endpoint. Switch models per task — route fast tasks to cheap models automatically.
Built-in updater checks for new releases in the background. One click to install — signed binaries, verified on-device before applying.
JMart Studio is in private preview. Enter your email to receive a 30-day license key instantly.
The preview is free for 30 days with a license key. After the preview period, JMart Studio will be a one-time purchase — no subscriptions for the core IDE. You bring your own AI API keys or run local models free of charge.
Yes, for local models (Ollama). The IDE, code intelligence, kanban, terminal, and secrets manager all work without an internet connection. Cloud AI features (Anthropic, OpenAI) require connectivity only for those API calls.
Any model accessible via an OpenAI-compatible API — including Anthropic Claude, OpenAI GPT-4o, and local models via Ollama (Llama 3, Mistral, Qwen, and hundreds more). You can add multiple providers and route tasks between them.
Only when you explicitly use a cloud AI model and include file context in a prompt. The codebase index, search, symbols, git state, and all local features never leave your machine. You are always in control of what gets sent.
macOS on Apple Silicon (M1 and later — signed & notarized), Windows x64 (NSIS installer), and Linux x64 (Debian .deb package) — all available above. macOS and Windows update themselves in-app; the Linux build is download-only for now (re-download to update).
This preview's Windows build isn't Authenticode code-signed yet, so SmartScreen flags it. Click More info → Run anyway to install — it's safe. Code signing is on the roadmap; the macOS build is already fully signed and notarized.
JMart Studio runs a local Model Context Protocol server on port 3456. This lets Claude Code, Cursor, and other MCP-compatible AI agents access your project's live context — file tree, symbols, git status, terminal — directly from their own sessions.
