CloserAI

A local-first, model-agnostic, permission-transparent desktop AI workbench for real Chat + Work + Code/Cowork outcomes. Built on DeepSeek Harness.

简体中文 | English

CloserAI is an open-source desktop application that wraps a DeepSeek Harness process in a hardened Electron shell. It is not a reskin: it adds a desktop supervisor, three permission-isolated working modes (Chat / Work / Code), local-first session storage, provider management with OS-keychain secrets, and a plugin safety model — while delegating the agent runtime to DSH.

Status

Pre-release — v0.0.4. The project is under active construction toward a v0.1.0 daily-use release. See docs/STATUS.md for the current milestone and docs/EXECUTION_PLAN.md for the full roadmap.

Milestones

Version	Scope	Status
v0.0.1	Bootstrap: monorepo, tooling, mock provider, CI	Released
v0.0.2	Desktop shell: DSH supervisor + hardened Electron window	Released
v0.0.3	Onboarding, OS-keychain secrets, DeepSeek/OpenAI-compatible providers, mock mode	Released
v0.0.4	Chat / Work / Code permission-isolated profiles	Released
v0.0.5	Daily conversation: session persistence, history, projects, file handling	In progress

What works today

• Hardened Electron shell: single instance, deep links, strict CSP, locked-down navigation, sandboxed preload.
• Crash-recovering DSH child-process supervisor with a random loopback port.
• First-run onboarding (Chinese UI) for DeepSeek, any OpenAI-compatible provider, or offline mock.
• API keys encrypted with the OS keychain and injected only into the DSH child environment.
• Three isolation modes: Chat (no shell/filesystem), Work (app-sandbox filesystem, no shell), Code (full shell/filesystem/terminal/plans/subagents over an authorized directory).

Principles

• Local-first & BYOK — bring your own API key; secrets live in the OS keychain, never in logs, files, or the renderer.
• Model-agnostic — DeepSeek and any OpenAI-compatible provider, plus a deterministic mock provider for offline use.
• Permission-transparent — three capability-isolated modes enforced through DSH agent presets and the sandbox workspace root, not prompt wording alone.
• Own identity — CloserAI has its own name and UI; it only credits "Built on DeepSeek Harness".
