What they are

Publer

Publer is a social media scheduling tool that covers publishing, analytics, and AI-assisted caption writing across platforms including Instagram, TikTok, LinkedIn, and Pinterest. It suits solo creators, agencies, and small teams who manage multiple accounts. The free plan is genuinely usable but limits the number of connected accounts, and the pricing climbs noticeably once you add team members or workspaces.

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.
