KeyboardAI: AI-Driven Keyboard

KeyboardAI replaces or extends the standard iOS keyboard with an AI writing layer. After installing it and enabling the keyboard in Settings, you can call up AI suggestions from inside Messages, Mail, social apps, and other text fields. Rather than switching to a separate chatbot, you describe what you want in plain language and the app produces polished text, which you then insert into the active field. The developer has steadily expanded the model lineup: version history shows the addition of Claude 3.7 and DeepSeek R1/V3 vendors, plus dedicated rephrase and translation features.

The app is built around a citation-free, single-purpose workflow: generate, rewrite, or translate. Tone and style controls let you steer output toward a formal email or a casual reply, and a word-count control sets roughly how long the response should be. A dashboard-type interface and an onboarding flow guide new users through setup, and the 2.0 release added an interactive GPT-based chat assistant for questions and suggestions that go beyond short replies.

KeyboardAI is a freemium product. The core app is free to download, and longer or higher-volume use is metered with token packages purchased as in-app items, so heavy users should expect recurring costs. It is an independent third-party utility and is not affiliated with Apple, OpenAI, Anthropic, or DeepSeek; the AI models it offers are reached through the app's own provider configuration.
