Caliptic Translate is a real-time speech translation application for macOS and Windows. It translates audio from meetings, videos, YouTube, podcasts, and face-to-face conversations as they happen. The software processes all transcription and translation locally on the user’s device, meaning no audio data is sent to external servers. This on-device architecture ensures that transcripts and translations remain private and do not require an internet connection once the application is installed. The application supports 22 languages and offers two-way translation: it can translate incoming speech into the user’s language, and it can also deliver the user’s spoken words into a meeting in another language through a virtual microphone. Features include system audio capture, ambient mode for in-person conversations, spoken translation voices, and a higher accuracy model option. The free tier provides 40 minute translation sessions that can be reset without requiring an account or payment. A paid tier removes session limits and adds priority support and free updates. Typical use cases include translating video calls on platforms such as Zoom, Google Meet, Microsoft Teams, Webex, and Slack huddles. It also works with online courses from Udemy, Coursera, and YouTube tutorials, as well as voice chat in Discord, TeamSpeak, and in-game communication. The ambient mode allows translation of offline conversations by using the device’s microphone. The workflow involves selecting the source and target languages, then playing or joining audio content; the translation appears as text or spoken output in real time. Technical requirements include macOS 15 or later, or Windows 10 or later. The application is optimized for Apple Silicon on Macs and runs fully offline after the initial installation. No account creation is needed to use the free tier. The software does not impose monthly minute quotas or daily limits, and it does not store transcripts on remote servers.
