Paster

Menu bar clipboard history, plus a screenshot tool that annotates and pins.

Paster lives in the menu bar. Press ⌥⌘V and the panel opens over whatever you are working in — without taking focus, so your app stays frontmost and ⌘V still pastes where you left off. Everything you have copied is there: text, rich text, images, files, each row showing which app it came from and how long ago.

The other half is a screenshot tool. ⌥⌘S freezes the screen, snaps the selection to whatever window you hover, and gives you a pixel magnifier that reads the exact colour under the pointer. Mark the capture up, then copy it — or pin it to the screen as a floating window that stays above every other app.

No account. No ads. No tracking. Paster makes no network connections of any kind — it has no code that can reach the internet, and it runs fully sandboxed.

Clipboard History

Everything, automatically: text, rich text, images and files, kept as you copy them.
No pile-ups: copy the same thing twice and it returns to the top rather than appearing again.
Search that works in CJK: substring search across the whole history, including Chinese, Japanese and Korean.
Filter, favourite, enlarge: narrow by type, star the clips you keep coming back to, and open any image or long text at full size.
Provenance: every row shows the app it came from and when.

Colours Get Their Own Tab

Copy a colour in any notation and Paster draws it as a swatch instead of a string of characters. One click converts it to the notations you have not written yet — HEX, RGB, HSL, HSB — and copies it. Transparency shows over a checkerboard rather than quietly disappearing.

Screenshot and Annotation

⌥⌘S freezes the screen and hands you a selection; hover a window and the selection snaps to it.
A pixel magnifier reads the exact colour under the pointer in HEX or RGB.
Full annotation set: rectangle, ellipse, line, arrow, pencil, marker, text, numbered badges, mosaic and blur.
Undo and redo anything, including strokes hidden under a mosaic.
Return copies it, or save a PNG.

Pin It to the Screen

Pin any image as a floating window that stays above every other app.
Drag it, scroll to resize, hold a modifier and scroll to fade it.
Pins survive a restart — they come back exactly where you left them.
A screenshot pins onto the pixels it was taken from, so the screen looks frozen in place.

Whiteboard

⌥⌘W opens a blank canvas with the same annotation tools. Or send an image straight from the history into one with ⌘E.

Nothing Leaves Your Mac

There is no account, no sync, no telemetry and no backend. Clips that an app marks confidential — the nspasteboard.org convention password managers follow — are never recorded. History is capped at 1,000 items and 30 days; favourites and pinned images are never swept.
