MewuAI is an open-source desktop Agent app for Windows, macOS, and Linux. Select screen content and express what you need through annotations, freehand drawings, and files. Chat, organize references, generate interactive tools, and use plugins to act in the same space. Mewu with you — working alongside you.

_{Capture, ask, and annotate in place.}

• Personal Agent: choose a role, model, tools, and memory, and reference images, videos, and files in conversation. Read Markdown, formulas, and model-provided reasoning. Long conversations can compact context while preserving the original history for retrieval. Use the official Agent's persistent local memory or connect an independent memory service.
• Local tools and skills: the built-in Agent can read, write, edit, and search files, run commands and scripts through Shell / PowerShell, and stop execution when you cancel a task. Portable SKILL.md skills can include scripts and references. Bundled skills cover image annotation, video annotation, interactive objects, and task verification; ordinary local tasks need no custom plugin.
• AI creative canvas: arrange, resize, pin, or save images, videos, text, and generated objects. Describe interactive HTML / SVG / Canvas content, use the resulting calculator, experiment, or game in the workspace, and ask for further changes.
• Capture and multiple selections: capture a region, multiple areas, scrolling content, or supported windows. Selections automatically become references while the surrounding screen dims, with no separate “Reference” click.
• Quick interaction: open with a configurable hold shortcut, select and copy recognized text, capture a region, or pin an image. The interface closes after a successful image/video copy or pin. With a voice plugin enabled, you can also start tasks by voice. See Hooks for setup and shortcuts.
• Drawing and AI annotation: pens, arrows, shapes, text, numbering, highlights, and mosaic, with undo, redo, and object editing. Annotate manually or ask AI to add construction lines, formulas, tables, and explanations to worksheet images, code, and other references. Generated annotations remain editable.
• Text and tables: local OCR, capture translation, chart understanding, and table extraction. Windows/macOS also offer actionable recognition of links, emails, phone numbers, QR codes, and barcodes.
• Recording and video annotation: capture system audio and microphone input; pause, resume, trim, and export MP4 / MP3 / GIF. Annotate manually or ask AI to use video frames to add rectangles and text over specific time ranges. Edit or undo annotations, and click conversation timestamps to revisit frames. Audio support varies by system.
• Blackboard: draw and explain on a full-screen board, combining questions, formulas, and AI analysis. Dock the toolbar to any of the four edges. A setting lets screen-sharing apps see selections and annotations.
• CLI and region AI operations: local Agents can inspect scenes, capture, add selections, draw, and export. The region plugin lets a model observe a selected target, act, and check a fresh screenshot before continuing.
• Plugins and event triggers: extend Agents, memory, tools, and UI independently. Official Hooks supports schedules, prompts, completed replies, press or hold shortcuts, and app/plugin events, connecting Mewu operations, MCP, commands, and keyboard/mouse actions. Theme plugins contribute shared colors and backgrounds, with cross-window updates and restoration when disabled or removed.
• Self-made plugins: describe a need to the built-in Agent to create, validate, and package a plugin project. Review permissions before installation under Plugins → Installed → Self-made. Plugins can reorder the original screenshot toolbar through the generic layout service. See skills and authoring.

Capture, drawing, and recording work without AI setup. AI conversations, translation, and generated content require a configured service.

• Reference-guided generation and dedicated image/video model connections.
• Circle-to-search, a desktop companion plugin, and more desktop collaboration workflows.
• Android x86 support for classroom interactive displays and TV systems.
• Messaging channel integrations.
• Exporting and sharing interactive workspaces.
• One-click sharing.
• Broader platform coverage, language support, and performance improvements.

Exam annotation Explain a worksheet and add construction lines, reasoning, and annotations to the original.	Generate HTML tools Describe a tool, generate interactive content, and keep using and refining it.
AI creative canvas Arrange storyboards, images, and conversations to develop a creative project.	Blackboard Draw axes, curves, and notes by hand to explain your reasoning.
Video annotations Annotate time ranges, play the result, and click timestamps to revisit the relevant frames.	CLI capture and drawing Call capture, selection, and drawing operations from a terminal and see the results in Mewu.
Text recognition Extract the text you need from a capture using local OCR.	Code explanation Select code, explain its logic, mark the failing line, and show a correction beside the original.
Table extraction Turn a captured table into structured data you can copy, compare, and use for further analysis.	External Agents Connect Codex, MiniMax Code, WorkBuddy / CodeBuddy, or Hermes to the existing conversation bar.

1. Install and launch. Choose your platform above. Windows uses WebView2; on macOS, move the app into Applications; on Linux, make the AppImage executable. Downloads follow the latest stable release.
2. Enter the workspace. Open Mewu from the tray or a capture shortcut to select, draw, save, or open a blackboard. Configure capture shortcuts in Settings → Capture & recording, and quick interaction and automation rules in Settings → Hooks. Grant system capture/recording permissions when requested.
3. Connect AI. Add a model in Settings → Agents & Connections, choose a role and memory, or connect a client through External Agents. Selections become references automatically; send your task from the conversation bar.

For Linux dependencies and permissions, see the AppImage guide and recording guide. Region AI operations support Windows, macOS, and compatible GNOME 50 Wayland x64 setups; Linux also requires Desktop Witness and Portal authorization.

Image, video, tool calling, and thinking effort support, as well as usage limits and fees, depend on the selected service. Leave thinking effort unset to use the provider's default. External Agents require the corresponding client to be installed and signed in; consult each plugin's documentation for platform support.

Browse, install, and manage extensions in Settings → Plugins, or import a release ZIP. Browse the full marketplace.

You can also describe what you need to the built-in Agent and ask it to create a plugin. For example, send:

Generate a Mewu plugin that adds OpenClaw channel support.

The Agent can load the plugin-authoring skill to create, validate, and package the plugin. Once it is ready, review its permissions and install it under Plugins → Installed → Self-made. See skills and plugin authoring.

Start the desktop app, then open a terminal. The CLI shares the same Mewu workspace with you:

mewu                         # Start an Agent conversation
mewu status                  # Inspect the app and current scene
mewu schema                  # Discover operations and parameters
mewu call capture.open --json '{}' --wait
mewu call capture.quick --json '{}' --wait

Plain mewu chat sends text by default; screenshots and files require explicit references. See the CLI guide and operation catalog for setup, platform requirements, and parameters.

Bug reports, use cases, code, plugins, and documentation contributions are welcome. The desktop app uses Rust + Tauri 2 + SolidJS / TypeScript + SQLite and renders through the system WebView.
