Writing assistants
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.

Hi PH 👋 I'm a solo developer from Japan.
I built Henji because I was tired of the same loop: ask ChatGPT for a reply, get something polished but not me, then rewrite the whole thing. The AI was doing the wrong half of the work — it was thinking for me, when all I actually needed was help putting my own thoughts into words.
So Henji flips it. You stay in charge of what to say; it handles how to write it — in your voice. Under the hood it learns your real writing style over time, so replies stop sounding like an AI and start sounding like you. That "wait, this is exactly how I'd say it" moment is the whole product.
