DeepChat is a local-first desktop client that puts chat models, tools, skills, and agent runtimes in one Electron application for Windows, macOS, and Linux. It talks to cloud APIs and to locally deployed Ollama models through the same interface, stores chat and configuration data locally, and supports network proxies and screen-projection hiding.
Sessions follow the Tape.systems approach: a session Tape records structured work history so context, tool calls, requests, and results stay recoverable and resumable, and trace previews expose the request sequence, provider and model metadata, Tape view manifests, included entries, and token budgets for long-running agent work.
Three extension surfaces sit alongside the chat window. Skills follow the Agent Skills specification and can be installed from folders, ZIP files, or URLs, enabled per conversation, and exchanged with other compatible tools; built-in skills cover generative art, code review, document collaboration, DOCX, PDF, PPTX, XLSX, frontend design, git commit messages, MCP building, and web artifacts. Agent Client Protocol (ACP) support runs external agent runtimes as first-class entries in the model selector, with a workspace view for plans, tool calls, and terminal output. Model Context Protocol (MCP) support covers resources, prompts, and tools over StreamableHTTP, SSE, and stdio transports, plus in-memory services for code execution, web retrieval, and file operations, and one-click installation through DeepLinks.
Remote control binds a running session to a messaging channel — Telegram, Feishu/Lark, QQBot, Discord, or WeChat iLink — so you can start sessions, switch models, answer pending permission prompts, stop a run, or open the session on the desktop with commands such as /new, /sessions, /use, /stop, /pending, and /status.
