Download & Install
Download the DMG, open it, and drag Clasp Helper to your Applications folder. It's signed and notarized by Apple — no Gatekeeper warnings.
Clasp on the App Store is fully functional and powerful. But Apple's sandbox restrictions prevent some features that power users need — like pasting directly into other apps, intercepting keystrokes for text expansion, and capturing screenshots automatically.
Clasp Helper runs outside the sandbox to unlock these capabilities. It's free, signed and notarized by Apple, and communicates securely with Clasp through a shared local database. No data ever leaves your Mac.
Without the helper, Clasp copies items to your clipboard and you press Cmd+V. With the helper, Clasp pastes directly into the active app — no extra step needed.
Register system-wide keyboard shortcuts that work in any app, even when Clasp isn't in the foreground.
The helper monitors your keystrokes and instantly expands snippet triggers as you type — in any app, system-wide. No need to open Clasp or use the keyboard extension.
{date}, {time}, {clipboard}, {uuid}The helper watches your screenshot directory and automatically imports every screenshot into Clasp — with OCR text extraction so you can search by what's in the image.
Set per-app rules that automatically transform clipboard content before pasting. Strip tracking parameters from URLs, force plain text in terminals, pretty-print JSON in code editors.
Three steps, under a minute.
Download the DMG, open it, and drag Clasp Helper to your Applications folder. It's signed and notarized by Apple — no Gatekeeper warnings.
On first launch, Clasp Helper will guide you to System Settings → Privacy & Security → Accessibility. This permission lets it paste into other apps and expand text. It's local-only — no data leaves your Mac.
Clasp Helper runs silently in your menu bar and connects to Clasp automatically. Your clipboard history, snippets, and settings sync through a shared local database.
No. Clasp from the App Store is fully functional on its own. The helper is an optional add-on for power users who want paste injection, system-wide hotkeys, and real-time text expansion.
Apple's App Store requires apps to run in a sandbox that prevents simulating keyboard shortcuts in other apps and monitoring keystrokes for text expansion. These are the core features of the helper, so it must be distributed outside the App Store.
Yes. Clasp Helper only simulates Cmd+V (and similar shortcuts) when you explicitly trigger a paste from Clasp. It never reads content from other apps or monitors anything beyond your own keystrokes for text expansion triggers. The app is notarized by Apple, which means macOS has verified it's free of malware.
Yes. Clasp Helper uses Sparkle (the industry-standard macOS update framework) to check for updates automatically. You'll see a notification when a new version is available.
macOS 14 (Sonoma) or later, same as Clasp.
