Every feature made for AI.

Stash is the first screenshot tool made for agentic coding. Every capture is composited with an AI Context Banner — app, window title, OS, display, appearance (light/dark), timestamp, and an 8-character capture shortID — so Claude Code, Cursor, ChatGPT, Windsurf, and GitHub Copilot Chat always know what they're looking at. Your arrows and rectangles are described as structured callouts, not confused with the original UI.

• AI Context Banner composited directly onto every screenshot:
  • App name and window title
  • OS version, appearance (light/dark), display resolution
  • Timestamp and 8-character capture shortID (#XXXXXXXX) for MCP lookups
  • Color space and scale factor
• Annotations (arrows, rectangles, ellipses) are described in structured text metadata
• AI reads annotations as user callouts, not as part of the original UI
• Solves the "visual context gap" — AI tools strip image metadata and can't distinguish annotations from UI elements
• Works with Claude, ChatGPT, Cursor, Windsurf, GitHub Copilot Chat, and any multimodal AI

When you paste a screenshot into Claude or ChatGPT, AI tools strip standard image metadata (EXIF, IPTC). They can't tell which app the screenshot is from, what OS version you're running, or whether your red arrow is part of the UI or your annotation. Stash composites an AI Context Banner directly onto the image and converts your annotations into structured text metadata. The AI sees something like Visual Studio Code — main.ts · dark · macOS 14.2 · 2026-04-20 10:14 · #5B8B643F — plus descriptions of your callouts. No typing required. (Also ideal for vibe coding workflows.)

How AI Context Banners work →

Stash ships a local Model Context Protocol server so Claude Code, Claude Desktop, Cursor, and other MCP-speaking agents can query your captures by name or ID. The one-line installer auto-configures the official three; the server listens on a Unix domain socket — no cloud relay, no network traffic, nothing leaves your Mac to use it.

• Auto-configures Claude Code, Claude Desktop, and Cursor with one command
• Local socket only (~/Library/Application Support/Stash/mcp.sock) — no cloud relay, no network traffic
• Five tools agents can call:
  • stash.list_recent(n) — newest-first summaries of your recent captures
  • stash.search(query) — substring search across app, window title, bookmark, text content, URL
  • stash.get_capture(id) — full dossier for a screenshot (app/window/URL/a11y tree/annotations)
  • stash.get_bundle(id) — video bundle with report, per-frame metadata, and audio path
  • stash.render_plain(id) — token-minimal plain-text rendering for inline paste
• Versioned stash-1 protocol — agent instructions don't break when Stash updates
• Peer-auth allowlist — only clients you've approved can connect
• Other MCP clients (Windsurf, Zed, ChatGPT Desktop, Codex CLI) work via manual setup

Why MCP beats pasting a screenshot into a chat: when you drag a PNG into most chat clients, the XMP metadata and accessibility sidecars get stripped on upload. MCP delivers the entire dossier — app/window/URL, pristine accessibility tree, annotation geometry, dev context for code editors — in a single tool call, without you reaching for the clipboard. A full video session costs an agent ~6–10K tokens for the structured context; the same session uploaded as files would cost 50K+ and arrive with weaker grounding.

Show a quick walkthrough, a visual bug or a product update in a short loop. Share GIFs in email and Slack, or upload one to X so people can see a moving demo directly in the feed. Playback depends on the app and viewer’s settings.

• Dedicated GIF shortcut (⌃⌘G) — choose a window, region or full screen
• Trim and copy — select the few seconds that make your point
• Automatic size fitting — adjusts export dimensions and frame rate to fit the selected sharing limit
• Original video retained — use it when you need sound, detail or a longer explanation
• AI context retained — the source capture keeps its extracted frames and context report; include those separate files when sharing with an agent

There is a time for video and a time for a GIF. Use the short loop to explain one action, and the full recording when the story needs more room.

Why GIFs can be better than video recordings →

Take screenshots, add arrows and annotations, and share with one click. Built for agentic coders who move fast, want fewer clicks, and paste visuals into AI chat dozens of times a day.

• ⌘⌃S to capture (region, window, or full screen)
• Built-in annotation: arrows, rectangles, ellipses, blur
• Compact color picker (7 colors)
• Auto-copy on each edit — no save step
• One-click sharing workflow

Press ⌘⌃S, select the region, and an annotation overlay appears instantly. Draw an arrow to point at the bug, add a rectangle around the UI element, blur sensitive data. The moment you draw, the annotated image is copied to your clipboard automatically. No save dialog, no file management, no exporting. Just ⌘V into Claude, Cursor, Slack, Jira, or any app that accepts images.

Assign keyboard shortcuts to your most-used clips. Press the hotkey from any app and it pastes instantly. For terminal AI tools like Claude Code, ⌘⌃P pastes a file path plus enriched context — the one shortcut that bridges GUI screenshots and terminal agents. The same paste works over SSH: a terminal on a headless Mac or Linux box can't accept a pasted image, but it takes a file path. Save captures to a synced folder and the path resolves on the agent's host.

• Up to 20 custom keyboard shortcuts
• Press hotkey from any app — content pastes instantly
• Auto-assigned on bookmark creation
• Default shortcut: ⌘⇧V to open Stash
• File-path paste (⌘⌃P) — for Claude Code, Cursor terminal, and other agentic CLIs that read images from disk
• Headless and remote agents — SSH'd into a headless Mac or Linux machine, you can't paste an image into the terminal; you paste the file path instead. See the headless workflow

Bookmark your system prompt, code review template, Zoom link, or email signature. Assign a hotkey like ⌘J or ⌘K. Press it from anywhere — Claude, Cursor, Slack, email, browser, terminal — and it pastes instantly. No app switching, no scrolling, no searching.
