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.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
