How to use an AI keyboard on Reddit
Typing on Reddit usually means bouncing to another app every time you want to translate a reply, fix a typo, or make sense of a wall of comments. An AI keyboard removes that friction — it puts writing tools inside the keyboard itself, so they work wherever you are typing. Here is how to set one up on Reddit and use it well, using Redkit as the example.
What an AI keyboard actually is
A regular keyboard turns taps into letters. An AI keyboard adds a row of tools on top: fix grammar, rewrite a sentence, translate, summarize, explain, or draft a reply — acting on whatever you have typed or selected. Because it is a system keyboard, it works in every app on your phone, not just Reddit. Redkit's keyboard runs these tools on its own private model, so your text is not shipped to a third-party AI or used to train anyone.
How to set it up
1) Install the Redkit app on iOS or Android. 2) Sign in with Reddit SSO — no Reddit password is shared. 3) In your phone settings, add Redkit as a keyboard and allow it. 4) Switch to the Redkit keyboard with the globe key whenever you want the AI tools. Setup takes about a minute, and you can flip back to your usual keyboard any time.
Using it on Reddit
Open a Reddit comment box or chat and switch to the Redkit keyboard. Type your message, then tap a tool: Grammar to fix mistakes, Improve to rewrite it clearer, Translate to change languages, or Reply Helper to draft a response in the tone you want. Tap to insert the result, and undo if you change your mind. Starting a post instead? Post Helper can generate the title, body, subreddit and flair. You can even quick-share a video, voice note or file as a playable card without leaving the keyboard.
Keeping it private
Because the tools run on Redkit's own model, nothing you type is sent to an outside AI or stored after the result appears. Sign-in uses Reddit SSO rather than your password, and the AI is quota-aware — the free tier covers everyday use, with Pro lifting the limits. Privacy-first means the convenience does not cost you your data.
