Slanki is a quick and dirty tool that queries users from a Slack team and then uses genanki to create an Anki deck with a set of really simple FullName / Photo cards for each person in the Slack team.
Copy/rename .env-sample to .env, and then the only value you actually need to change is the SLACK_API_TOKEN. To get that, you’ll either need to create a Slack app or maybe use a legacy token (I don’t know if a legacy token would work, YMMV).
I created an App at https://api.slack.com/apps?new_app=1 , with OAuth scopes identity.avatar:read:user, users:read, and users.profile:read.
On my app’s “OAuth & Permission” tab, I generated a workspace token. That token looks like xoxo-12345-56789-8675309-whatever. Take that token and put it in your .env file as the SLACK_API_TOKEN.
You can run it with pipenv run python slanki.py; it should churn for a while downloading avatar images into a temporary directory. Finally it should pop out an .apkg file suitable for loading into Anki.
If your Slack team is anything like mine, you’ll have dozens of bot accounts / fake users from integrations, so you’ll either want to prune them from your Anki deck by hand or else add their names to the set(['slackbot']) of excluded names.
