What they are
Runway
Runway is a browser-based AI video platform used by filmmakers, social media creators, and marketing teams to generate, edit, and transform video with text and image prompts. Its Gen-4 Alpha model produces short video clips from text or images, while traditional editing tools sit alongside AI features in one workspace. Output quality impresses at short durations, but longer or complex scenes still require significant iteration.
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.
