Our verdict on Kotoba Simultaneous Interpreter
Kotoba Simultaneous Interpreter is a mobile app for translating live speech into subtitles, aimed at people handling conversations, meetings, travel, or customer service across languages. It runs on iOS and Android and supports two-way dialogue through a QR-linked mode, so speakers can connect for a translated exchange. Its main appeal is immediate access to translated speech on a phone; teams looking for desktop-first interpreting should look elsewhere.
The Free plan includes real-time subtitles and live translation, with 21 input languages and 13 output languages. The monthly Unlimited plan costs $99 and adds unlimited translation time and translation history while retaining Free features. An annual Unlimited plan is listed at $999.99 with the same highlights. Enterprise is listed at $95 per device per month and adds unlimited translation, centralized member management, and priority support. Enterprise Volume lists the interpreter app and Meeting Bot, support for Google Meet, Zoom, and Microsoft Teams, and two-way translation across Japanese, English, Chinese, and Korean. Those enterprise options make the product more relevant to organizations standardizing meeting translation than to users who only need occasional travel help.
The feature set stays focused on spoken translation: subtitles may appear before a speaker finishes, users can save or share translation text, and Unlimited adds translation history. The vendor says Koto voice AI powers core language pairs, with external models used for some others. That distinction may matter to buyers evaluating language coverage rather than just headline counts. Kotoba is a fit for mobile conversations and meetings where subtitles and two-way dialogue are the priority. It is less suited to teams requiring a desktop app, or buyers whose needs exceed the stated language coverage; Enterprise Volume specifies four languages for its two-way translation offering.
