Give DeepSeek a pair of extra hands: instantly use Skills, with long-term memory, browser control and toolchain! Open-source plugin, DeepSeek++

DeepSeek++ extends the DeepSeek web version into an AI Agent workbench supporting Chinese/English experience, memory, projects, Skills, MCP, multimodal media, browser control, saved items, artifact downloads, conversation export, and automation. Simply put - install it and your DeepSeek upgrades from a disposable chat tool to an agent that remembers you, can call tools, and works automatically.

Unlike the official version that forgets after chatting, DeepSeek++ lets AI automatically identify key information in conversations and save it as cross-conversation long-term memory, automatically injecting relevant context next time you chat, so you never need to re-introduce yourself.

Key Highlights

Native-like tool calling: The extension identifies tool calls in real-time within the SSE stream and executes them automatically. Results render as collapsible blocks, keeping DeepSeek's native look. Multiple tool calls can execute sequentially in one reply, and display restores after refresh.

MCP Tool System: Supports Streamable HTTP, HTTP POST, SSE, local stdio bridge, and Chrome Native Messaging protocols. New services auto-execute by default. The sidebar lets you test connections, refresh tools, and view latency and errors.

Memory System: When AI identifies key information in conversation, it automatically calls memory_save to store as long-term memory. Supports four types: user profile, behavior feedback, topic context, and reference materials. Sidebar allows viewing, editing, pinning, and deleting memories.

Skill System: Built-in 9 ready-to-use skills covering deep thinking, frontend design, document collaboration, PPT design and more. Type / in the chat box to bring up the completion panel; selecting a skill auto-injects the corresponding prompt.

System Prompt Presets: Create multiple presets defining global role settings or behavior instructions. One-click activation applies automatically to every new conversation.

Automation Tasks: Supports manual run and cron/RRULE scheduled triggers (minimum 15-minute interval). Each task has an independent session for continuous topic tracking. Task list shows next run time, last run status, and error reasons.
