Two kinds of tools
Everything Plumón can do, in one place.
An everyday toolkit for marking up any screenshot: capture it, point at it, box it in, hide what shouldn't be there. And four smart tools that go further: pulling text back out, stitching a whole scroll, catching personal info, and drawing focus. Jump to either, or just scroll.
Everyday toolkit
The basics, done right.
Every capture opens ready to mark up. These work exactly like you'd expect, no setup, no digging through menus.
Capture
Region Snap
Drag a box over anything on screen, get just that.
Timed Snap
Set a delay, get the window or menu open the way you want it, then it fires.
Window Snap
Just the active window, no desktop clutter around it.
Full Screen Snap
One press, the whole display.
Annotate
Arrow
Click, drag, point at exactly the thing that matters.
Text
Click, type a caption, done.
Stamp
Drop a checkmark, an X, a question mark, or an emoji right on the shot.
Numbered
Click to drop 1, 2, 3 that stay in order as you go.
Pen
Freehand draw, any color, any width.
Frame & focus
Crop
Trim the shot down to just what matters. The one you'll use the most.
Black-out box
Drag over anything to hide it completely, a name, a logo, a face. Manual, for whatever "Hide personal info" below doesn't catch on its own.
Blur
Softens what's underneath instead of covering it outright.
Highlighter
A streak of color over text, never covers it.
Shapes
Rectangle, oval, or line, to box in what matters.
The 4 smart tools
Beyond the basics: four features built specifically for the screens you actually capture. Each demo below is a short animated walkthrough of how it works in the app.
Copy text straight out of a screenshot.
Drag a box over any text and get back an editable, copyable result you can fix before it hits your clipboard, or grab everything on the screen in one press.
- Grab a region for a preview you can correct first
- Grab all for a one-press copy of every text block
- Recognition happens on your Mac; nothing is sent anywhere to read it
Grab Text: region-with-preview, instant copy, or grab all
Capture the whole conversation, however far it scrolls.
Frame the scroll area, then scroll normally while Plumón grabs frames and stitches the overlap live, so a long thread or page becomes a single shot instead of six.
- Adjustable frame keeps window chrome and sticky headers out of the shot
- A live growing preview shows the stitch is clean as you go
- Scrolling back up doesn't duplicate content
Scrolling Capture: frame it once, you scroll, Plumón stitches
Catch the emails, phone numbers, and account numbers in a shot. Black them out in one press.
Plumón proposes what it found. You confirm it, dismiss a false flag, or click anything it missed. Nothing is redacted until you say so, and the scan never leaves your Mac.
- Detects emails, phone numbers, SSN-style numbers, and card- or account-length numbers
- Names and addresses aren't auto-detected, since detectors miss non-English names too often; click any of them to add a box
- Composes with the Black-out box tool for a face or logo
Hide personal info: it proposes, you confirm
Dim everything except the one thing you're pointing at.
Draw a box around what matters and the rest fades. Move it, resize it, or remove it later. Nothing underneath is touched.
- A normal, revisable layer, not a one-shot effect
- Dim strength is adjustable
- Combine it with arrows or numbered steps to point inside the spotlight
Spotlight: dim the surroundings, change nothing else
Works with your AI
Just tell your AI what you want.
Plumón ships with a command an assistant like Claude can run on its own. It's inside the app you download; nothing separate to install. Ask your assistant in plain English to redact the personal details, add numbered steps, and frame a screenshot, and it hands you the finished guide. The command uses the same engine that powers the app, just without a window. For anyone who builds step-by-step procedures, training docs, or how-tos for a team, a folder of raw screenshots becomes a finished set of guides without editing each one by hand.
Two-step setup: in Plumón, open Settings → Command Line → Install… (one click puts plumon on your PATH), then paste this into your assistant's standing instructions (CLAUDE.md, AGENTS.md, or a system prompt):
This machine has Plumón, a headless screenshot EDITOR CLI (annotate, redact, callouts, numbered steps — it does NOT capture). Before building any image-annotation tooling, run `plumon help` and `plumon schema`.
The full walkthrough is in the app: open Help → CLI & AI Guide.
Ask Claude in plain English; it runs Plumón and hands back the guide
