Cross-platform clipboard history manager — lives in your system tray, stores every copy, lets you search and re-paste instantly.
Everyone uses a clipboard. Almost no one uses the same one twice.
macOS hides its history behind a setting most people never find. Windows has Win+V. Linux has a dozen tray applets, each with its own quirks. The moment you switch machines — or switch operating systems during a workday — the muscle memory breaks. Different shortcut, different window, different behavior, and your history stays trapped on the box that captured it.
cut-tool collapses that into one experience. The same tray icon, the same Cmd/Ctrl+Shift+V, the same search-and-repaste flow on all three platforms. Underneath, each OS is served by its native mechanism — CGO/NSPasteboard on macOS, atotto/clipboard on Windows and Linux — so capture is fast and correct everywhere; on top, the interaction is identical.
That consistency is a design choice, not an accident. History lives in a local SQLite database driven by pure-Go modernc.org/sqlite (no CGO), which is exactly what lets one codebase cross-compile and behave the same across macOS, Windows, and Linux. Nothing leaves your machine — no cloud, no sync, no account.
- Clipboard history — captures every text copy automatically
- Image support — copy an image, it's captured too; the list shows a thumbnail, click to paste it back
- Instant search — filter history with a real-time search box
- Pin entries — star (★) important snippets to keep them at the top
- Global hotkey —
Cmd+Shift+V(macOS) /Ctrl+Shift+V(Windows/Linux) opens history from anywhere - Sensitive content filter — skips password-manager entries (macOS:
org.nspasteboard.ConcealedType) - System tray — always running, zero taskbar footprint
- Persistent storage — SQLite, survives restarts, keeps the latest 500 entries
| Platform | Clipboard (text + image) | Hotkey | Tray |
|---|---|---|---|
| macOS 12+ | ✅ NSPasteboard (CGO) | ✅ Cmd+Shift+V | ✅ |
| Windows 10+ | ✅ Win32 (pure Go) | ✅ Ctrl+Shift+V | ✅ |
| Linux (X11) | ✅ X11 via purego | ✅ Ctrl+Shift+V |

- Launch
cut-tool— a ✂ icon appears in the menu bar / system tray - Copy text as usual — it's captured automatically
- Press
Cmd+Shift+V(or click Show History in the tray) to open the history window - Type to search, click an entry to paste it back to the clipboard
- Click ☆ to pin an entry — pinned items always appear at the top

cut-tool 是一个跨平台桌面剪贴板增强工具，常驻系统托盘，自动记录每次复制内容，支持快速搜索和一键回填。
剪贴板人人在用，但几乎没人用的是同一套。
macOS 的历史藏在多数人从没打开过的设置里，Windows 靠 Win+V，Linux 则有一堆各具脾气的托盘小工具。一旦换台机器——或者一个工作日里在几个系统间来回切——肌肉记忆就断了：快捷键不同、窗口不同、行为不同，历史还各存各的，锁死在当初捕获它的那台设备上。
cut-tool 把这些收敛成同一种体验：三端都是同一个托盘图标、同一个 Cmd/Ctrl+Shift+V、同一套搜索与回填流程。底层各走原生机制——macOS 用 CGO/NSPasteboard，Windows 和 Linux 用 atotto/clipboard——保证各平台捕获都快而准；上层交互则完全一致。
这种一致性是刻意的工程取舍，而非巧合。历史记录存在本地 SQLite，由纯 Go 的 modernc.org/sqlite 驱动（无 CGO），正是这一点让同一份代码能交叉编译、在 macOS / Windows / Linux 上表现如一。数据不出本机——无云端、无同步、无账号。
- 剪贴板历史 — 自动捕获每次复制的文字
- 图片支持 — 复制图片同样记录，列表显示缩略图，点击即回填
- 实时搜索 — 在搜索框输入关键字即时过滤
- 置顶收藏 — 点击 ★ 固定常用内容，始终排在最前
- 全局快捷键 —
Cmd+Shift+V（macOS）/Ctrl+Shift+V（Win/Linux）随时唤出 - 敏感内容过滤 — 自动跳过密码管理器写入的条目（macOS）
- SQLite 持久化 — 重启不丢失，保留最近 500 条
# macOS
go build -o cut-tool . && ./cut-tool
# Linux
sudo apt install gcc libgl1-mesa-dev xorg-dev
go build -o cut-tool . && ./cut-tool首次运行需在 系统设置 → 隐私与安全性 → 辅助功能 中为 go 授权，之后全局快捷键才能生效。
