Add Placet to your Slack workspace. A /placet command builds the vote with your team; voting happens on the web (with real methods: approval, majority judgment, Condorcet…) and the result comes back to the channel.
Placet requests the minimal permissions (commands, chat:write) to post and update voting messages. Ballots stay on the web; no voter needs an account. Type /placet help in Slack anytime.
