Mesmerizing
A space for images, sounds and thoughts.
macOS · CHF 20 · One-time
Your visual moodboard as a native Mac app. Drag images, videos, voice notes, 3D models, PDFs or text files straight into the window — they become freely arrangeable tiles you move, resize and view in light or dark. Everything lives as real files in a folder on your Mac: no database, no account, no cloud. Runs fully offline. Buy once, use forever.
What it does
Drag anything in
Images, videos, audio, 3D models, PDFs, text, code and Markdown — just drag them into the window. Every file becomes a tile.
A real preview for every format
3D models spin, PDFs and design files show a still, text and code open up to read right in the board — not just file icons.
Arrange and resize freely
Move tiles by drag & drop, three sizes each — order and sizes are remembered.
Light & dark
One click on the background flips the whole board — right into the window chrome.
Mark for Claude
Mark an image on its tile and use it straight from Claude Code — “take the marked image”, no upload, no detour.
100% local, no subscription
Your media stays as normal files in your folder. No cloud, no account, no subscription — buy once, use forever.
Frequently asked questions
Where are my files stored?
In a folder you choose on your Mac, as plain files. You can open it in Finder anytime — Mesmerizing is just the nice view on top.
Does Mesmerizing need internet or a server?
No, Mesmerizing runs fully offline on your Mac. Internet is only needed once, briefly, to activate the license.
Which file formats does Mesmerizing understand?
Images (JPG, PNG, WebP, GIF, HEIC, TIFF, AVIF), video (MP4, WebM, MOV), audio (MP3, WAV, M4A and more), 3D models (GLB, OBJ, STL, STEP, IGES), PDF and many design/office files as previews, plus text, code and Markdown.
What does “Mark for Claude” mean?
Mesmerizing plays nicely alongside Claude Code: mark an image on its tile and refer to it directly in a Claude Code session — no uploading or dragging in. Handy when you work with your reference images.
Is there a subscription?
No. Mesmerizing is a one-time purchase — pay once, use forever. Updates within the major version included.
Does Mesmerizing work as a moodboard or reference board?
That is exactly what it is built for: arrange reference images, clips and notes freely on a canvas — except everything lives with you as real files instead of in someone's cloud. Great for designers, photographers and anyone who thinks visually.
