Features

Core Capabilities

• Autonomous Agent — More than chat: plans, invokes tools, reads/writes files, executes commands, and completes complex tasks end-to-end
• Plan Mode — For high-risk steps (delete / overwrite / send / install), Abu first presents a step-by-step plan and waits for you to click "Confirm & run"; only read-only ops run while awaiting approval
• Interactive questions — When Abu needs you to decide (pick an approach, provide a parameter), it pops an option card above the composer; single or multi-select, with an "Other" free-text row
• Per-conversation settings — Permission mode (Request Approval / Smart Review / Full Autonomy) and model can be switched per conversation without bleeding across chats
• Soul Personality System — Three proactivity presets (Quiet / Buddy / Butler) decide when Abu speaks up; customize tone, address, reply style, and boundaries via SOUL.md
• Self-Evolving Skills — After you run a multi-step complex flow, Abu proactively offers "want to crystallize this into a skill?" — one click drafts it, you review, you accept. Next time, just name the skill; no need to re-explain
• Smart Notification System — Menubar unread count / sidebar badge / system notification auto-routed; notices queued to inbox while you're in fullscreen / DnD, surfaced via badges once you're back; audit trail kept for 180 days
• Projects — Promote a workspace into a Project: conversations in the same direction auto-aggregate; each project gets its own default model, skill set, and MCP connectors
• Multi-Agent Parallel Execution — Run up to 5 background agents simultaneously, each executing tasks independently with real-time progress tracking
• Desktop Pet (Labs) — Transparent floating window; left-click opens main window, right-click menu, drag-to-edge dock; activity tray shows Abu's live status (working / awaiting approval / done) and lets you reply inline while it waits
• Theme switching — Light / dark / system, via Settings → Appearance
• Labs — In-progress features, off by default, opt-in, may change or be removed (currently hosting: Desktop Pet)
• Conversation Sharing — Export any conversation to JSON in one click; API keys and local paths are auto-redacted before sharing
• 29 Built-in Skills — PDF/PPTX/DOCX/Excel generation, frontend design, canvas design, algorithmic art, Mermaid/SVG/infographics, Abu's built-in browser, optional Chrome bridge, deep research, Agent self-reflection (reflect), workflow automation, and more — one-click install, fully customizable
• MCP Protocol — Connect to databases, search engines, GitHub, and other external services via Model Context Protocol
• Browser Automation — Zero-setup built-in browser for ordinary web tasks, plus an optional Chrome extension bridge for existing tabs and signed-in sessions
• Computer Use — Screenshot + mouse/keyboard control for desktop-level tasks, with sensitive app blocking, dangerous key interception, and a 5-minute session timeout
• HTTP Fetch — Built-in safety gateway: URL length cap, embedded credential blocking, cloud metadata endpoint blocking, 10 MB download limit, 60-second timeout — no more raw curl blind spots

AI Services & Models

• 12+ Cloud Providers — Anthropic Claude, OpenAI, DeepSeek, Qwen (Bailian), Doubao (Volcengine), Moonshot, Zhipu GLM, MiniMax, SiliconFlow, Qiniu, OpenRouter, and more
• Local Models — Zero-config Ollama integration with automatic local model discovery
• Custom Endpoints — Connect any OpenAI-compatible or Anthropic-compatible API
• Provider Management — Add, edit, delete, reorder providers with connection health checks and latency detection
• Model Selector — Switch models on-the-fly during conversations with capability badges (vision, tool use, web search, thinking, image generation, long context)
• Favorites & History — Star frequently used models, quickly switch between recent ones
• Image Generation — Built-in DALL-E 2 / DALL-E 3 support, plus any custom image-generation endpoint

Web Search

• Multiple Search Engines — Bing, Brave, Tavily, SearXNG (self-hosted, no API key needed)
• Independent Configuration — Search engine settings decoupled from main AI service

Automation & Triggers

• Scheduled Tasks — Cron-based scheduling (e.g., daily AI news digest at 9 AM); runs missed while the app was closed are replayed in time order on next launch
• Trigger System — Multiple event sources to automatically invoke agents:

• Trigger Permission Model — Four capability levels (read-only → safe tools → full access → custom whitelist) for fine-grained control

IM Channel Integration

Turn Abu into your team bot — just @Abu in your chat:

• Supported Platforms — D-Chat, Feishu (Lark), DingTalk, WeCom, Slack
• Session Management — Auto-isolate conversations by user/group/thread, auto-archive on timeout, "continue last" recovery
• Security Controls — User allowlist, workspace path restrictions, capability level enforcement
• Response Modes — Mention-only or all-messages

Memory & Context

• Three-tier file-based memory (Memdir architecture):

• Project Rules (hand-written):

• Project Aggregation — Promote a workspace into a Project to aggregate its conversations; older conversations auto-backfilled with projectId on startup. Each project can independently configure default model, skill set, and MCP connectors
• Session Memory — Large tool outputs automatically persisted to disk; compact summaries kept in-context to prevent context explosion
• Persistent Todos — Per-conversation todo_write plans persisted to disk and survive app restarts
• Auto-Compaction — Intelligently compresses long conversation history while preserving key context

Security & Privacy

• Three Permission Modes — Request Approval (free read/write inside workspace; out-of-bounds writes and dangerous commands need confirmation; default) / Smart Review (out-of-bounds ops go to an AI reviewer: allow low-risk, block high-risk, ask only when unsure) / Full Autonomy (everything runs automatically except hard system red-lines); global default in Settings → Sandbox, also switchable per conversation via the chip above the composer
• Content Safety Scan — Scans agent-authored skills / memory entries to catch dangerous instructions, prompt injection, hardware commands, and 120+ other risk patterns
• OS Sandbox (macOS only) — macOS Seatbelt (sandbox-exec) confines a shell command's file access to the workspace. Windows has no OS-enforced sandbox: PowerShell ConstrainedLanguage restricts in-process language features, not file access, and a child powershell.exe does not inherit it. Treat Windows shell containment as advisory, not as a security boundary
• Network Isolation — Local proxy + domain allowlist + private-network toggle. Enforced through environment variables, not by the OS: a command that bypasses the proxy (curl --noproxy, a runtime with its own proxy settings) still reaches the network. On Windows the toggle is not exposed in Settings and isolation is off by default
• Path & Command Safety — Sensitive directories (system folders, SSH keys, etc.) blocked by default; dangerous commands (rm -rf /, etc.) caught statically
• Computer Use Safeguards — Blocked sensitive apps (terminals, system settings, credential managers, IDEs), dangerous key interception (Cmd+Q, Cmd+Tab, Force Quit, Win+R), per-app grants you can revoke, confirmation before any consequential action, 5-minute timeout. These govern the Computer Use tool; they do not constrain the shell tool, which can reach the desktop by other means while no OS sandbox is in place
• Encrypted API Key Storage — Windows DPAPI / macOS AES-256-GCM with a hardware-UUID-derived key; keys are no longer written to localStorage in plaintext
• Local-First — Your data stays local, your API keys stay local — nothing goes through third-party servers
• Cross-Platform — Supports macOS (Apple Silicon / Intel) and Windows

Diagnostics & Troubleshooting

• One-Click Self-Check — Settings → Diagnostic, runs through AI service connectivity, data & permissions, MCP, skills, network, app environment
• Diagnostic Bundle Export — When something breaks, package logs / config / version info in one click (API keys and paths auto-redacted) and send it to the maintainer
