KeysAI

KeysAI, listed as Grammar AI Keyboard: KeysAI, is an AI writing keyboard for iPhone made by Zerovik. It replaces the standard keyboard with one that checks text for typos and grammar mistakes and can generate or rewrite text. KeysAI is aimed at anyone who writes on a phone, including people composing emails, social media posts and notes, and it is listed in the App Store's Productivity category.

KeysAI works as a keyboard extension, so its tools are available inside the apps where a user already types rather than in a separate editor. The user composes a message as usual, and KeysAI checks the writing, offers alternative word choices and can translate the message in real time without copying and pasting it elsewhere. It also gives real-time feedback intended to help users refine their writing.

The main capabilities of KeysAI are grammar and spelling checks across a range of languages, wording suggestions, real-time translation, automated message completion that continues a message from its context, and paraphrasing for producing rewritten, plagiarism-free versions of a text. AI text generation helps users find words for what they want to say, and the keyboard is meant to work across all platforms and applications on the device.

KeysAI is free to download, with a KeysAI Full Access subscription billed weekly or yearly. Listed in-app purchases include Keys AI Premium weekly at $2.99 or $7.99, annual at $29.99 or $39.99, and lifetime at $49.99, $59.99 or $69.99. Subscriptions renew unless cancelled at least 24 hours before the period ends. KeysAI runs only on iPhone, requires iOS 16.0 or later, and its interface is in English.
