Japanese Input System 'ATOK Passport' Begins Offering AI-Powered Writing Assistant 'ATOK MiRA' for macOS, Android, and iOS Starting June 29 (Mon)

JUSTSYSTEMS Corporation (Headquarters: Minato-ku, Tokyo; President and CEO: Kota Sekinami) announces the launch of 'ATOK MiRA' (Eitokumira), an AI-powered writing assistant, for macOS, Android, and iOS as part of the 'ATOK Passport' service—providing continuous access to the latest Japanese input system—starting today, June 29 (Mon).

'ATOK MiRA' Now Available Across 4 Operating Systems, Enabling Use from Any Device

With support across Windows, macOS, Android, and iOS through 'ATOK Passport', the writing assistant 'ATOK MiRA', previously available only for Windows, is now accessible on all four operating systems. This enables users to leverage the writing assistant across all devices, including PCs and smartphones.

'ATOK MiRA' combines ATOK's Japanese language processing technology with generative AI tailored to individual input patterns, offering personalized and natural text suggestions. Without needing to launch a separate app or enter prompts (instructions), users can simply invoke the feature via the 'ATOK MiRA icon' and select predefined commands such as 'Refine Text' or 'Add Emoji' to easily generate ideas, edit, summarize, or rewrite text.

Enhanced Conversion Performance for Fragmented Input on Mobile Devices

The conversion engine for Android and iOS has been upgraded. Optimized for the smartphone-specific input style of confirming words individually while viewing predictive suggestions, the update improves conversion accuracy for fragmented input starting with particles and for words containing附属 elements (e.g., auxiliary verbs).

For example, previously, after confirming '経験' (experience), typing 'のうむ' next would be processed independently and incorrectly converted to '濃霧' (dense fog). The new engine correctly interprets such fragmented input in context, converting it accurately to '経験の有無' (whether or not one has experience) in a single step. Additionally, conversion accuracy for common daily expressions containing附属 elements like '〜たい' ('want to') and '〜よう' has been enhanced. This enables more natural and seamless Japanese input, whether composing long texts or engaging in fast-paced messaging on social media.

[Overview of ATOK Passport]

'ATOK Passport' is a Japanese input system supporting four operating systems—Windows, macOS, Android, and iOS—and usable on up to 10 devices simultaneously.

It delivers a consistently up-to-date and comfortable input environment, whether in the office or on the go.

FAQ

Q: What is ATOK?

A: ATOK is a Japanese input method editor (IME) first released in 1982 that was among the first to incorporate AI (artificial intelligence) conversion and has continued evolving ever since. Its key features include the comprehensive 'ATOK Conversion Dictionary'—covering everything from trendy terms and IT jargon to business terminology, place names, and dialects (spoken language)—and a conversion engine refined over decades, enabling efficient Japanese text creation.

By combining dictionary data, contextual understanding, and individual input characteristics, ATOK achieves accurate homophone disambiguation and automatic correction of input errors, supporting natural, personalized Japanese input for each user.

Q: Why choose the paid 'ATOK Passport' when free input software is available?

A: The key advantages are its superior text proofing capabilities and the ability to maintain a consistent input environment across multiple devices. It comes standard with high-end electronic dictionaries like 'Kōjien', allowing users to instantly verify nuances and correct usage examples, enhancing text reliability. Furthermore, the latest 'ATOK Passport' supports four operating systems and enables real-time synchronization across up to 10 devices. It is chosen by users who demand 'error-free, refined writing' in professional and writing contexts.

Q: How is the AI-powered writing assistant 'ATOK MiRA' different from typical AI tools?

A: Unlike typical AI tools that require launching a browser or separate app and entering prompts, ATOK MiRA allows one-tap text editing and rewriting directly from the input screen. Moreover, by combining decades of Japanese language processing expertise with personalized input settings, it delivers naturally flowing text suggestions that avoid a mechanical tone.

Q: What specific improvements does this update bring to text input on smartphones such as Android and iOS?

A: 'ATOK MiRA', previously available only on Windows, is now accessible on smartphones. Additionally, the application of AI technology to the mobile conversion engine significantly improves accuracy for fragmented input typical on smartphones (e.g., typing 'のうむ' after confirming '経験') and for everyday conversational expressions containing附属 elements (e.g., '寝てたい'). This greatly reduces input frustration caused by incorrect conversions.

Q: Is additional payment or special registration required to use 'ATOK MiRA' or the new conversion features on macOS, Android, and iOS?

A: No additional fees or new registration are required. Customers currently subscribed to 'ATOK Passport [Premium]' can access all features simply by updating the 'ATOK' app on each OS to the latest version.
