Foist, Slack's suspicious-message detective

Why it surfaced

Foist builds an evidence board for messages like “Let's leverage this opportunity to unlock meaningful synergies,” then offers to draft an even more aggressively AI-sounding reply. It is free to self-host, MIT licensed, and careful to say it is not an AI detector or proof of authorship.

An open-source Slack tool that examines overly polished workplace prose and assigns it a low, medium, or high suspicion reading.
