What they are
ConvertKit
ConvertKit is an email marketing platform aimed at bloggers, podcasters, course creators, and independent writers who need to grow and monetize a subscriber list. It combines email broadcasts, automated sequences, landing pages, and a paid newsletter feature in one place. The interface is simpler than enterprise tools like Mailchimp or ActiveCampaign, which makes onboarding fast but limits advanced design flexibility.
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.
