What they are

Opus Clip

Opus Clip uses AI to analyze long-form video content and extract the most engaging moments as short clips sized for TikTok, Reels, and Shorts. Creators, marketers, and podcasters use it to repurpose existing content without manual editing. The AI scoring system ranks clips by predicted virality, which is a useful starting point, though its judgment does not always align with your specific audience.

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.
