Down to where they should look

“Here, like this” lands with teammates and AI alike.

A plain screenshot often fails to say where to look. Box the spot that matters and add a few words about what should change.

Copy the image into the conversation, and everyone is looking at the same place.

The request list without annotation. Nothing shows where to look or what is being asked. — What the reader gets“Where, and what should change?”They see the screen. Not the request.

The request list with the deadline column boxed, an arrow, and the note 締切が近い順に並べたい (sort by nearest deadline). — What the reader gets“Sort by deadline, nearest first.”Where to look, and what to do.

From capture to annotation

Arrows and notes, right there.

Select a region and the detail window opens. Choose Edit to annotate the image in place.

Point with an arrow, box what matters, add text, hide with mosaic. The annotated image is saved as a separate file; the original stays by default.

Editing tools

Copy for wherever it goes.

Choose Copy Image to paste into a conversation. Slack, Discord, email, and AI assistants all take it.

Stored where you are

Your captures never go to the cloud on their own.

They are kept safely on your Mac, and only there.

Captures, GIFs and MP4s are saved to the folder you choose. No Shottan account, no uploads, no usage tracking.

To share, you pick the image and copy it yourself. If the folder is synced, or you paste into an outside service, it travels through that service.

Captures and annotated images only ever land in your save folder on your Mac. Nothing goes to the cloud.

Look back, show motion

Every past capture, and motion as a GIF or MP4.

For finding an earlier capture, and for the things a single image cannot explain.

Past captures, by month.

Browse the images, GIFs and MP4s in your save folder by month, and search by file name.

The Shottan gallery, listing the images and GIFs in the save folder by month, with a file-name search field at the top. — Images, GIFs and MP4s in one gallery.

Motion, with Shottan GIF.

Select a region and record with the companion app, Shottan GIF. Trim the ends, choose GIF or MP4, and it lands in the same folder.

The Shottan GIF trim window: a preview of the recording and a timeline for setting the start and end. — Keep just the part you need, as a GIF or MP4.

Frequently asked questions

Storage, sharing, originals, and how to get it.

Are my captures sent anywhere?

Shottan never uploads images or videos. They are saved to the folder you choose, and no usage data is collected. If that folder is synced (iCloud Drive, for example), or you paste an image into an outside service, it travels through that service.

How do I share an image?

Choose Copy Image and paste it into a chat or document. There are no sharing URLs. The Markdown copied by Share references a file on your own Mac, so sending it as-is will not share the image.

Does annotating overwrite the original?

No. The annotated image is saved as a separate file and the original stays by default. If you tick “Delete the original”, the original is moved to the Trash after saving.

How do I get it?

Shottan is coming soon to the Mac App Store. Once released, the buttons on this page will take you there. It requires macOS 14 or later and installs two apps, Shottan and Shottan GIF. Screen Recording permission is required on first capture. The app interface is in Japanese.
