In their own words:

Otter saves you time (and money). Transcribe audio instantly, capture and find what you need, jump from a summary keyword to see all instances in a note, or search across everything. Speed up the playback or skip silence to skim through a long recording. Otter plays well with others — keep everyone on the same page with live notes that render in real time. Because Otter is powered by Ambient Voice Intelligence, it’s always learning.
