Context Sender

Chrome extension to copy diffs, PRs, and Jira ticket details to your clipboard or download them as text files — optimized for pasting into LLMs.

How It Works

GitLab / GitHub

When you're on a merge request or pull request page, the extension:

1. Detects the MR/PR URL and shows a badge on the extension icon
2. Fetches the raw diff (e.g. merge_requests/113.diff)
3. Lets you copy the diff to your clipboard or download it as a .diff file

Jira

When you're on an Atlassian Jira ticket page, the extension:

1. Detects the issue key and shows a "JIRA" badge on the extension icon
2. Fetches the ticket via the Jira REST API v3 (summary, description, and comments)
3. Converts the Atlassian Document Format (ADF) response into clean, readable plain text
4. Lets you copy the ticket details or download them as a .txt file

Supported ADF elements include panels, ordered/bullet/task lists, tables, code blocks, mentions, emoji, inline cards, blockquotes, and more.

You can then paste the content into ChatGPT, Claude, or any other LLM for review.
