API key setup is a bit tedious.

Ask a GPT-style model to complete or rewrite your text straight from a button on the keyboard you already use.
Pre-built starting points for emails, tweets, pickup lines, and social captions remove the blank-page problem.
Recommendations try to match the tone and intent of what you are already typing so suggestions stay coherent.

Typing and prediction run locally while AI generation is routed through the OpenAI API you configure.
Smart Typer takes the idea of an AI chatbot and folds it into the most used surface on your phone: the keyboard. Once it is set as your default input method, a dedicated key lets you ask an AI model to continue, rephrase, or generate text without leaving the app you are writing in. That makes it useful for quick wins — finishing a sentence in a message, polishing an email, or drafting a tweet — rather than for long-form editing.
A big part of the appeal is the bundled prompt templates. Rather than staring at a blank AI prompt box, you pick a category such as email, tweet, or social post and adapt the scaffold to your situation. The app then feeds that into the model and returns coherent, on-topic text you can drop into your draft.
Practically, Smart Typer is a hosted keyboard wrapper around the OpenAI API: you supply your own API key, which means AI generation depends on your OpenAI account and usage. It is published by developer X-SLAYER, has tens of thousands of installs on Google Play, and is distributed as a free, ad-supported app updated for current Android versions.
Draft replies, follow-ups, and short professional notes from a template without switching apps.
Generate captions, tweets, and replies in seconds while staying inside the social app.
Get sentence completion and light rewriting help as you type in any messaging app.
