PromptPaste

AI text assistant for Android

PromptPaste is an AI text assistant that lets you correct, rewrite, transform, and run custom AI actions on selected text.

It works with multiple AI providers and allows you to create your own actions using prompts and variables.

Your API keys stay on your device and are protected using Android Keystore.

How It Works

Android controls how applications can access and modify text from other apps.

PromptPaste uses official Android integrations:

1. Select text in any supported app.
2. Choose a PromptPaste action from the selection menu.
3. PromptPaste processes the text.
4. Review and replace the result.

Some applications do not expose editable text or hide Android selection actions.

For these apps, PromptPaste provides an optional action keyboard.

Action Keyboard

The optional PromptPaste Actions keyboard provides another way to run AI actions.

1. Enable PromptPaste Actions in Android settings.
2. Switch to the PromptPaste keyboard.
3. Choose an action such as Correct, Rewrite, or a custom action.

The keyboard only reads selected text after you explicitly trigger an action.

It does not monitor typing and is disabled in password fields.

AI Providers

PromptPaste supports:

• Local AI models through Ollama
• Cloud providers through their APIs

Each action can use its own provider and model configuration.

Privacy

PromptPaste is designed with privacy in mind.

The app:

• Only sends text when you explicitly run an action
• Stores API keys locally using Android Keystore
• Does not collect analytics
• Does not monitor clipboard activity
• Does not use accessibility services
• Does not require an account

Cloud providers have their own privacy policies, retention rules, and usage limits.

Review their policies before sending sensitive information.

Build

Requirements:

• JDK 17 or newer
• Android SDK Platform 37
• Android SDK Build Tools 36 or newer

Build debug APK:

./gradlew assembleDebug

APK output:

Run verification:

./gradlew testDebugUnitTest assembleDebug lintDebug

Ollama

For local Ollama servers:

• 127.0.0.1 refers to the Android device itself.
• Android emulators usually reach the host machine through http://10.0.2.2:11434.
• Physical devices normally require the computer's local network address.

Ollama must listen on an address reachable by the Android device.

Related Projects

PromptPaste is available across multiple platforms:

• GNOME Shell extension
• Android app
• Browser extensions

The goal is to provide the same AI text workflow everywhere.
