Black One / Desktop app / Windows release online

Black One app icon

Your models. One desktop.

Black One is a local-first AI workspace for Windows. Chat with any provider, run real terminals, manage work on a Todo board, and delegate to CLI coding agents — without giving your data to the cloud.

What it does

Everything you need to turn an idea into shipped code.

Provider independent

Switch between cloud providers or a local endpoint without rebuilding your context.

Native multi-terminal deck

Real PTY shells in grid, horizontal, or vertical layouts. PowerShell, CMD, Bash, and Zsh.

CLI coding agents

Install and run terminal-first agents alongside cloud chat models, all from one UI.

Todo board

Kanban lanes with drag-and-drop, per-lane models, and builder/reviewer multi-agent passes.

File & shell tools

Read, edit, list, and run commands with permission modes from Manual to YOLO.

Long-term memory

Save project context, preferences, and facts that get injected into future prompts.

Quick Chat shortcut

A global floating chat window for fast questions that land in the main workspace.

Local by design

Sessions in SQLite, API keys in the OS credential store, no cloud required for the app.

Code view

Chat on the left. Terminals on the right. Context in the middle.

Code view is the primary workspace: a chat composer with file, folder, image, URL, and clipboard attachments, plus a dock of native PTY terminals. Tool calls collapse into expandable "Thinking" blocks so you see the final answer and can inspect every step.

Todo view

A Kanban board that actually runs the tasks.

Switch to Todo view for four priority lanes — Critical, High, Mid, Low. Drag and drop tasks, assign a model per lane, and let the runner execute from Critical to Low. Tasks use the current chat session and tool permissions, so context carries over.

CLI tools

Bring the agents you already use in the terminal.

First-run onboarding installs Codex, Claude Code, Gemini CLI, Kimi Code, and OpenCode in the background — no shell window required. Use them as standalone terminal agents, or let cloud chat models call file and shell tools through the same workspace.

Memory

It remembers the details so you do not have to repeat them.

Black One extracts <memory> blocks from model responses, categorizes them, and injects the most relevant entries back into future prompts. Memory is stored as JSONL and mirrored to Markdown, so you can always see — and edit — what the app knows.

Local-first

Your workspace lives on your machine.

Black One is a native Tauri app. Conversations are persisted in SQLite, API keys are guarded by the OS credential store, and file/shell access is bounded to the folders you attach.

Quick Chat

A thought should not need a full window.

Press the global shortcut to open a small floating chat, pick a model, attach context, and send. The conversation moves into the main workspace when you are ready for more room.

Release notes / security review

A few scanners say "suspicious." The evidence says "false positive."

The Windows installer is unsigned and uses Tauri's NSIS wrapper, which can download WebView2 and launch setup processes. That is normal installer behavior, not hidden app behavior.

The flagged signals line up with the NSIS installer, runtime WebView2 download, unsigned packaging, and legitimate shell and file permissions. Read the linked reports for the complete vendor and behavior details.
