Screenshot anything on your screen, scribble right on it, and send it — to your builder, your designer, your team, your students… or your AI. What took a paragraph now takes one pink arrow.
Free to start — no credit card, up and running in your browser today.
Install it and it just works — on any tab, logged in or not. Circle what's wrong, hit one key, and the screenshot lands in your downloads folder with your ink baked in. You never have to sign up for anything.
Want those shots saved into folders you can come back to, re-edit and export as PDF reports? That's what a plan is for →

MarkerBack lives in your browser — a dashboard with a built-in device preview, plus a Chrome extension for any live page.
Load a URL in the phone, tablet or desktop preview — or snap any live tab with the extension in one keystroke.
Marker, highlighter, arrows, numbered pins and text — right on the screenshot. It feels like a whiteboard, not a form.
Copy the marked-up shot into Slack, email, or an AI chat — or export the whole review as a tidy PDF for clients.
Telling Claude or ChatGPT "the button is misaligned somewhere on checkout" wastes three round-trips. Paste a MarkerBack shot instead — the arrow, the circle and your note travel with the pixels, and the AI fixes exactly what you pointed at.
Try it with your next bugAnything on your screen can be captured, scribbled on and sent — to a client, a builder, a student, a team… or an AI. Here’s what people actually do with it.
A builder sends the homeowner tomorrow’s kitchen render. The homeowner circles the island, moves the pendant lights with an arrow, writes “this wall in the sage green” — and sends it straight back. No site visit, no twenty-message thread.
The extension works right on top of YouTube, podcasts and online courses. Pause a tutorial, circle the exact chart or chord or setting on screen, add your note — and capture it into your study folder. Your notes finally have the picture attached.
Generate an image in any AI tool, then mark it up: an arrow for the motion you want in the video version, a circle where the product should sit, a note for the lighting. Copy the marked-up shot back into the chat — the AI sees precisely what you meant.
Freeze match footage on any screen, draw the run, circle the open player, number the sequence — then send the shot to the team group chat. Works for football, chess streams, esports VODs, anything you can pause.
Coding agents are brilliant at writing code and hopeless at guessing which button you meant. Screenshot the page, circle the broken spacing, arrow the misaligned card, drop a numbered pin on each thing you want changed — then paste that one image into Claude, ChatGPT or Cursor and say “fix 1, 2 and 3”. It sees exactly what you see, so it changes the right thing the first time instead of the third.
Agents mark up listing photos and floor plans: “this wall comes down”, “north-facing window here”, pin #1 on the water damage to ask about. Buyers send back their own circles. Every property gets its own folder, ready to compare.
No accounts for your clients, no plugins, no screen-recording marathons. Just the fastest way from "this looks wrong" to "here's exactly what to change".
iPhone, Android, tablet and full desktop views — auto-scaled, scrollable, capture-ready.
Hand-drawn-feel strokes in six colors and three sizes. Circle it, underline it, cross it out.
Drop #1, #2, #3 on the exact spots, then reference them in your notes. Zero ambiguity.
Click anywhere and type. Labels wrap automatically and can be dragged around freely.
Branded, numbered, prioritized — every screenshot and note laid out ready to forward.
Flattened, annotated screenshots straight to your clipboard — paste into Claude, ChatGPT or Cursor.
Flag what matters, tick off what's fixed. Your feedback list doubles as a to-do list.
Capture any tab in one keystroke and draw on live websites. Included with premium plans.

Every tool people reach for was built to make things. You're not making anything — you're pointing at something that already exists and saying "this bit, fix it". That job deserves ten seconds, not a design app.
Open the app, import the screenshot, add a layer, find the brush, pick a colour, export a PNG, hunt for the file, attach it. For an arrow.
Brilliant for making a poster. Wrong shape entirely for "the checkout button is broken on mobile" — you end up rebuilding the page just to draw on it.
Six minutes to record, six minutes to watch, and nobody can skim it. An AI can't read it, and neither can the person who joins the project next week.
"The thing under the header, next to the other thing — not that one, the one below." Three replies later you're both still guessing.
To be fair: if you need to actually design something — a logo, a poster, a brand kit — go use a design tool. They're great at that. MarkerBack does one thing: point at what's already on your screen and make it obvious.

The Chrome extension is free for everyone. Paid plans are what save your work into folders you can come back to — cancel anytime.
Grab the marker, circle what's wrong, hit export. Whoever's on the other end — human or AI — will know exactly what to do.
