What they are
Captions
Captions is a mobile-first AI video editor aimed at creators who produce talking-head content for social media. It auto-generates captions, removes filler words, corrects eye contact, and can clone your voice for overdubs. The app targets solo creators who want a post-production shortcut, though its desktop feature set is still catching up to its mobile counterpart.
Grok
Grok is a large language model chatbot built by xAI that answers questions, drafts content, analyzes data, and generates images. It pulls live information from X (formerly Twitter) and the broader web, making it more current than many competitors. Creators use it for research, writing assistance, and brainstorming. The free tier is limited in usage, and the personality-forward tone can occasionally prioritize wit over precision.
