Henji turns your half-formed thoughts into a finished reply that sounds like you — not a generic AI. Most AI tools think for you and hand back text in their voice, so you rewrite it anyway. Henji is the opposite: you keep the thinking, Henji just handles the writing. Select a message, drop a few keywords, and get a reply in your tone — ready to send. The more you use it, the more it learns your phrasing, your rhythm, your emoji habits. Starts with Slack. Built for anyone drowning in replies.
Henji is an AI writing tool that transforms incomplete thoughts into polished replies in the user's unique voice. It learns from user interactions to improve its output over time, initially integrating with Slack for enhanced productivity.
