We provide fastest AI models for everyday recording, high-accuracy AI models when every word matters, and multilingual AI models for different languages.

Local AI keeps track of speakers across recordings, helping you recognize the same people through meetings, interviews, and special memories. ► So instead of only searching for what was said, you can find who said it. ■ Never lose the original moment. A transcript should always lead you back to the source. Every sentence stays connected to its exact moment in the recording.
