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.
Sketch AI turns your voice into a one-glance graphic recording — not just a transcript. Record a meeting, brainstorm, or lecture, and AI lays it out visually in three styles: Simple (key points), Detailed (full coverage), or Manga (fun narrative). Generate multiple sketches per recording to compare angles. Built on Google Gemini, native iOS 26+.
