Banana Keyboard

Banana Keyboard is an Android keyboard designed to insert comprehensive AI prompts with a single tap.
Eliminate repetitive typing and copy-pasting across ChatGPT, Claude, Gemini, and notes apps.

【Privacy by Design: Insert-Only Architecture】
Q. Android shows a standard warning when enabling the keyboard ("This input method may be able to collect all text you type..."). Is it safe?
A. Yes, completely safe. Banana Keyboard is built strictly as an "Insert-Only" keyboard:

1. Zero text-reading APIs in our code:
We do not use any text-inspection APIs (such as getTextBeforeCursor, getTextAfterCursor, or getSelectedText). Banana Keyboard cannot read, intercept, or monitor your keystrokes or text in other apps. The keyboard only commits approved prompt text directly (commitText). Password fields automatically block insertion.

2. Never sends on its own:
It only pastes the selected prompt into your input field. It has no mechanism to trigger the send action (no IME_ACTION_SEND)—you always review the prompt and hit Send yourself.

3. History & favorites stay local:
Your recent prompts and favorite cards are stored exclusively on your device.

4. Network access is strictly limited:
Internet access is used solely for syncing prompt library updates and verifying purchases. It is never used during typing, and no user input is ever transmitted.

【Key Features】
・One-tap instant insertion: Populate long, structured prompts in a split second
・Smart auto-collapse: Keyboard automatically shrinks into a slim bar immediately after insertion so you can hit the Send button right away
・Curated prompt library: Business summaries, Anthropic official writing guidelines, and image generation styles
・Local history & favorites: Fast access to your favorite prompts
・Security guard: Automatic insertion lock in password input fields
・4 languages supported: English, Japanese, Korean, Traditional Chinese
