About

Henji

Features
Read full description

Henji is a keyboard with AI replies that learns how you actually write. Five generations a day, free forever — no card required. Copy the message you received, tap "Generate a reply," and in about three seconds a draft appears right in the text field — in your own phrasing, at your own level of formality. It works in any app: LINE, Slack, email. No app switching. 【Key Features】 ■ Generate a reply Turn a copied message into a reply in your voice, inserted straight into the field. ■ Compose a new message by voice Not just replies. Tap the mic, say what you want to send, and Henji writes it. If you have text on the clipboard, it can be used as the starting draft. ■ Personas Automatically switch tone for teammates, managers, or customers. You can also pick a different persona when regenerating. ■ Redo it by voice Say "make it shorter" or "offer three time slots" and Henji rewrites the draft with that instruction applied. ■ Go back to a version you liked Every regenerated draft is kept. Step back and forward through them and insert the one you prefer. ■ Quick replies One-tap insertion of the lines you send all day (works offline). 【About Full Access】 The Henji Keyboard works as a quick-reply keyboard without Full Access. Full Access is required only for AI generation and voice. Even with Full Access granted, Henji never collects or transmits your keystrokes. 【AI providers and your data】 Replies are generated using AI from Google (Gemini). Only when you tap "Generate a reply" is the target text — along with your instruction and your style rules — sent through Henji's server (henji.ai) to that provider. What you send is not stored on the server and is never used to train AI models. We explain this and ask for your consent during onboarding. If you decline, you can still use Henji as a quick-reply keyboard. 【Pricing】 ■ Free (no card required) Five generations a day, forever — ten on your very first day. Your allowance resets the next day. Regenerating does not count against it, so you can redo a draft as many times as you like. ■ Henji PRO (monthly or yearly, auto-renewing) For when five a day is not enough. New users can start with a 7-day free trial, after which the subscription renews automatically at $5.99 per month, or $59.99 per year. The yearly plan works out to about $5.00 per month, which saves about two months compared with paying monthly. ・Payment is charged to your Apple ID account at confirmation of purchase ・The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the period ・Your account is charged for renewal within 24 hours prior to the end of the current period ・You can cancel any time in Settings > Apple ID > Subscriptions on your iPhone ・Any unused portion of a free trial is forfeited when you purchase a subscription ・Terms of Use: https://henji.ai/en/terms ・Privacy Policy: https://henji.ai/en/privacy Quick replies work offline on both plans.
