What they are

Otter.ai

Otter.ai records, transcribes, and summarizes spoken audio in real time, syncing words to the original audio so you can search and replay any moment. Podcasters, interviewers, and content teams use it to turn conversations into searchable text without manual note-taking. Transcription accuracy is strong for clear speech but drops noticeably with heavy accents, crosstalk, or poor microphone quality.

Sonix

Sonix is an automated transcription service that converts audio and video files into text using AI, then lets you search, edit, and export transcripts in multiple formats. Journalists, podcasters, researchers, and video producers use it to speed up post-production workflows. Transcription accuracy is solid for clear audio but drops noticeably with heavy accents or poor recording conditions. There is no free tier, so you pay from the first minute.
