# Cullshot

Cullshot is an app for quickly **reviewing, culling and rating** photos – on Mac and iPad. It is built for the moment after a shoot, when hundreds of images sit on your memory card and you want to find the good ones.

{% hint style="success" %}
**Your originals stay untouched.** Cullshot never modifies an image file. Ratings are stored in XMP sidecar files next to the images and are compatible with Lightroom.
{% endhint %}

## What Cullshot can do

* **Review directly on the memory card** – no copying first.
* **Browse fast:** previews from the RAW files appear instantly, 100% zoom checks sharpness.
* **Rate:** Pick, Reject, 1–5 stars and color labels, all by key (or on iPad by tap and swipe).
* **On-device AI suggestions:** blurry images, closed eyes and bad exposures are flagged, and the best image of each series is suggested. The AI only suggests – you decide.
* **Detect series:** similar shots taken in quick succession are grouped.
* **Hand off:** to Lightroom, Capture One, Apple Photos or a folder – with embedded stars and labels.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cullshot.gitbook.io/cullix/readme.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
