Capture & annotate your screen from an AI agent: arrows, boxes, text, highlight, blur/redact.

Overview

AI-generated overview

Lets an AI assistant capture the screen, view the image, and annotate it with arrows, boxes, text, highlights, and blur or redaction.

What you can do
The desktop app doubles as a local MCP server exposing capture_fullscreen, capture_region, annotate, get_image, and save_image. An assistant can take a full-screen or region screenshot, look at the resulting image, draw annotations such as arrows, shapes, text, highlighter, mosaic redaction, and watermark, then save the result. Captures play an audible cue and processing stays on the machine.
When to use it
Useful when you want an assistant to produce visual bug reports, before-and-after proof, or annotated screenshots from a short instruction. It suits desktop workflows where the assistant needs to see what is on screen and mark it up.
Requirements
Runs as a local process on the user's machine and is desktop only. Install the desktop app (v1.2.0+), then add the server either through the npm launcher genai-capture-mcp with npx, or by pointing directly at the installed binary with the --mcp flag, which needs no Node. On macOS, grant Screen Recording permission or captures come back black.
Before you install
The server captures your screen, so anything visible on the desktop can be sent to the connected AI client; images only go to that client. On macOS the app is not notarized yet, so first launch may require allowing it under Privacy & Security. Screen Recording permission is required for capture to work.

Installation

In SourceWeft

  1. Open Genai Capture in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

GenAI Capture

[Downloads] [Latest release]

Screen capture + annotation, two ways:

  • Desktop app — capture the whole desktop, annotate (arrows, shapes, text, highlighter, mosaic redaction, watermark), then copy / save / pin. Global hotkeys, gallery, themes. Cross-platform (Java).
  • JetBrains IDE plugin (this repo's source) — the same engine inside any JetBrains IDE: GoLand, PhpStorm, PyCharm, WebStorm, IntelliJ, CLion, Rider, …

Download the desktop app

Grab the installer for your OS from Releases:

OSFile
macOSGenAI Capture-<version>.dmg
Windows (installer)GenAI Capture-<version>.exe
Windows (portable)GenAI-Capture-portable-win.zip

macOS note: the app isn't notarized yet. If macOS blocks the first launch, allow it under System Settings ▸ Privacy & Security ▸ "Open Anyway", and grant Screen Recording permission when asked. Details ship in the DMG's First Launch.txt.

The plugin is on the JetBrains Marketplace — search for GenAI Capture (or install the zip from Releases by hand).

Use with AI agents (MCP)

The desktop app (v1.2.0+) doubles as an MCP server: AI agents that speak the Model Context Protocol — Claude Code, Claude Desktop, Cursor, … — can capture your screen, look at the image, annotate it (arrows, boxes, text, highlight, blur/redact), and save the result. Visual bug reports and before/after proof, driven by one sentence to your AI.

Install the desktop app, then add the server to your client. Easiest (cross-platform, via the genai-capture-mcp launcher on npm):

bash
claude mcp add genai-capture -- npx -y genai-capture-mcp

Or point directly at the installed binary (no Node needed):

bash
claude mcp add genai-capture -- \  "/Applications/GenAI Capture.app/Contents/MacOS/GenAI Capture" --mcp

Tools: capture_fullscreen, capture_region, annotate, get_image, save_image. Captures play an audible cue; everything runs locally — images only go to the AI client you connected.


JetBrains IDE plugin

Brings the screenshot capture + annotation engine inside any JetBrains IDE (GoLand, PhpStorm, PyCharm, WebStorm, IntelliJ, CLion, Rider, …).

Features

  • Tools ▸ Take Screenshot — ⌘⇧1 (macOS) / Ctrl+Shift+1 (Win/Linux). Captures the whole desktop (IDE included) and opens the annotation overlay.
  • Tools ▸ Capture Desktop (Hide IDE) — ⌘⇧2 / Ctrl+Shift+2. Temporarily hides the IDE, captures the desktop behind it, and keeps the IDE hidden until you dismiss the overlay (ESC / save / copy / pin / close).
  • Tools ▸ Take Delayed Screenshot ▸ 3s / 5s / 10s — shows an on-screen countdown, then captures (time to switch windows or open a menu first).
  • Status-bar buttons — a camera icon (immediate capture) and a monitor icon (hide-IDE desktop capture). Toggle either via the status-bar right-click menu.
  • Annotation overlay — arrows, shapes, text, highlighter, mosaic redaction, watermark, with copy / save / pin.
  • Settings ▸ Tools ▸ GenAI Capture — a Watermark page (appearance, default text, behaviour, live preview) and a Toolbar page (choose/reorder the tools on the capture toolbar). All shortcuts are rebindable in Settings ▸ Keymap.

On macOS, grant the IDE Screen Recording permission (System Settings ▸ Privacy & Security ▸ Screen Recording) or the capture comes back black — same requirement as any screen-capture tool.

How it's built

It reuses the desktop app's code (../src/main/java + ../src/main/resources) via a Gradle Copy step that filters out the app shell and the parts that don't load inside the IDE's JBR (the osystem/ FFM code, jnativehook global-hotkey, tray, and the desktop-themed Settings panels). Thin FFM-free shims under src/main/java/io/genai/screenshot/ (osystem/AbstractOs, CaptureController, ScreenshotApp) satisfy the few OS calls the overlay makes. The capture itself uses java.awt.Robot (no native code). The plugin's own actions, settings pages, and status-bar widgets live under src/main/java/io/genai/screenshot/plugin/.

Built against the platform module only (com.intellij.modules.platform), so a single build runs in every JetBrains IDE.

Prerequisites

  • JDK 17+ (a JBR or any JDK 17+).
  • A JetBrains IDE installed (the build targets your local GoLand by default — see build.gradle.kts). To use a different IDE, edit the local("…") line, or switch to a downloaded one, e.g. intellijIdeaCommunity("2024.1").
  • Gradle: easiest is to open this jetbrains-plugin/ folder in IntelliJ IDEA (it imports the Gradle project and provides the wrapper). Or brew install gradle and run gradle wrapper once.

Run it (sandbox IDE)

bash
cd jetbrains-plugin./gradlew runIde          # launches GoLand with the plugin loaded

Then use Tools ▸ Take Screenshot (⌘⇧1) or the status-bar camera icon.

Build an installable plugin

bash
cd jetbrains-plugin./gradlew buildPlugin      # -> build/distributions/genai-capture-plugin-1.0.0.zip

Install in any IDE: Settings ▸ Plugins ▸ ⚙ ▸ Install Plugin from Disk… → pick the zip.

Notes / next steps

  • The reused overlay code is verified to compile at Java 17 with no FFM / jnativehook dependency.
  • First runIde may need minor tweaks to the IntelliJ Platform Gradle DSL or the local(...) IDE path for your exact versions — iterate from there.
  • Possible future options: capture a chosen region only, or a configurable default delay.
