One image, the whole story
A labeled contact-sheet montage you paste in a single message. No 40-attachment chat.
Free · Open source · Windows
Show your AI what you mean.
Flipbook captures your screen as a sequence of labeled frames — one clean montage you paste straight into Claude Code, Cursor, or Copilot. The animation, the glitch, the flow you couldn't put into words? Now your AI can see it.

01The problem
Typing out a moving UI is the worst.
You’ve tried it: “the menu flickers on the second open, but only after the page scrolls, and the easing feels off near the end…” Three paragraphs later, your AI still guesses wrong — because words can’t carry motion.
And a single screenshot is just one frozen instant of something that only makes sense in sequence.
02How it works
Capture it. Montage it. Paste it.
01
Capture
Hit a hotkey. Flipbook quietly grabs your screen — or just one window — frame by frame, on a timer or only when something actually changes.
02
Montage
It stitches the frames into one labeled grid. Every tile is stamped with its frame number and timestamp, so "between frame 4 and 5 it glitches" actually means something.
03
Hand it to your AI
Click Copy Montage, paste into your AI chat. It reads the sequence like video — the motion, the states, the glitch — and gets to work. Want a deeper read? Drop the full-res frames too.

03Features
Does one thing. Does it well.
Skip the boring frames
Capture-on-change keeps only the frames where something moved. No 200 identical stills to wade through.
Whole screen, or just the window
Capture one app via the native picker — no messy desktop in the shot.
Trigger and forget
Global hotkey plus system tray. The app hides itself, so it's never in your own screenshots.
Frames ordered like video
Lossless PNGs in a timestamped session folder, named so order and elapsed time read frame-by-frame.
100% local. Always.
Zero network requests. No telemetry, no account. Your screen never leaves your machine.
04Why frames
Why not just send a video?
Most AI models can't watch video — and the ones that can usually sample a few blurry frames and miss the exact moment that matters.
Discrete, labeled stills are what image models read best. Flipbook hands them a clean sequence instead of asking them to guess.

05Use cases
Where it earns its place.
Reproduce an animation you like
Capture a site's motion, hand over the frames, get a faithful starting point to build on.
Show a visual bug in motion
The flicker, jump, or layout shift a single screenshot can't catch.
Hand off a design flow
A multi-step interaction, frame by frame — no screen-share back-and-forth.
Document your own workflow
Keystrokes, mouse paths, app transitions — captured without remembering to hit record.
06Straight talk
What to expect.
// straight talk
Frames let your AI reproduce the look and approximate the motion. It's a brilliant head start for an animation or a faithful bug repro — not a frame-for-frame copy of a proprietary WebGL scene.
We'd rather tell you that up front.
07Privacy
Your screen is yours.
Flipbook makes zero network requests — no telemetry, no update pings, no account. Captures are written only to the folder you choose.

08FAQ
Questions, answered.
Which AI tools does it work with?
Anything you can paste an image into — Claude Code, Cursor, Copilot, ChatGPT, and friends.
Does my screen get uploaded anywhere?
No. It's 100% local, with no network calls at all.
Is it free?
Yes — free and open source.
What platforms?
Windows 11 (64-bit) today. One self-contained .exe — no .NET install needed.
Why does Windows show a blue warning on first run?
It's not code-signed yet. Click More info → Run anyway; Windows remembers after the first time.
What do I actually get?
Lossless PNG frames, a montage.png, and a metadata.json — in one timestamped folder per session.
Stop typing out the motion. Show it.

Like this? I build custom software for clients.
Flipbook is something I designed and shipped solo. Got an idea of your own — an app, an immersive site, a SaaS? I can build that too.
