Copy the contents of a Slack thread.
Great conversations happen in Slack. But once the conversation is over, how do you use what you've learned? You could rely on your memory, so your precious insights are as easy to find as your car keys. Or you could extract the content and store it in your favourite knowledge-management system, like Notion, Confluence, Obsidian or JIRA.
Unfortunately, when it comes to sharing data, Slack is pretty stubborn. Simply highlighting the text of a thread and copying it results in mostly garbage. If all your Slack administrators are similarly motivated, they might have installed third-party apps that tie into a corporate workflow.
So what if you just want the text of a Slack thread your way? You need slackclipper.
slackclipper uses your personal Slack account to copy the text you want in the format you prefer. Want to add a discussion to a JIRA issue? Store some golden knowledge in Obsidian? Reference some colleagues in your Notion? slackclipper enables it all. Simply provide it the thread you want to clip and it will return the content, formatted ready for its new life.
By default the clipped content will be neatly formatted in Markdown. But the data is yours! Customise the format, or even export to any format with an API. Prefer PDF, or Google Docs or even dictated audio? Go for it!
This project is not endorsed or authorised in any way by Slack Technologies LLC.
Note: requires Python 3.11 or earlier! This is a limitation of the leveldb package, which is used by the slacktokens dependency. The restriction is now enforced by the packaging, but pip and friends provide confusing error messages like "these package versions have conflicting dependencies.
With a compatible version of Python installed, just run:
pip install slackclipper
This will install the slackclipper library for advanced use within Python, but also installs a convenience executable by the same name, so you can run it directly from the command line.
- Copy the link to the thread in Slack.
- Run
slackclipperin your Terminal.
- Paste the result into the destination of your choice.
When slackclipper is run for the first time, it will attempt to extract your Slack credentials using slacktokens. You may be prompted for your password.
If extraction is successful, these credentials will be stored (in ~/.config/slackclipper/) for future use. To replace the store with freshly extracted credentials, run slackclipper with the -u or -update-credentials flag.
Support for when Slack is directly downloaded and installed, instead of installed through the Mac App Store, is broken in the current release version of the dependency pycookiecheat. However the fix has been merged into the repository. To apply it, you can do something like:
# Download the current version of the source file
curl -L https://raw.githubusercontent.com/n8henrie/pycookiecheat/refs/heads/master/src/pycookiecheat/chrome.py -o chrome.py
# Get the location of the pycookiecheat package on your computer
# Replace `python3` with the python you used to install slackclipper. Eg `python3.11`.
PACKAGE_PATH=$(python3 -c "import pycookiecheat, os; print(os.path.dirname(pycookiecheat.__file__))")
# Dry run to make sure the replacement is good. You should see a diff like that in the commit:
# https://github.com/n8henrie/pycookiecheat/commit/36f72082e9a6a77cf84c5000150e7f779d73b14d
diff chrome.py "$PACKAGE_PATH/chrome.py"
# Do the replacement
mv chrome.py "$PACKAGE_PATH/chrome.py"
slackclipperrelies onslacktokensto extract your Slack credentials.slacktokenscurrently only supports macOS and Linux.-
If credentials extraction fails for this or any other reason, credentials can be provided manually using Python like so:
>>> from slackclipper import update_credentials_store >>> update_credentials_store(creds) # where "creds" is in the format produced by slacktokens

- Only exports in a fixed MarkDown format for now.
