What they are
Bolt.new
Bolt.new is a browser-based AI app builder by StackBlitz that generates, runs, and deploys full-stack web applications from a plain-text prompt, with no local setup required. It uses WebContainers to execute code live in the browser, supports multiple JavaScript frameworks, and integrates with Supabase, GitHub, Figma, Netlify, and Stripe. Pricing runs on a token consumption model, where larger and more complex projects burn through allocations faster than simple prototypes. The free tier is genuinely usable for experiments, but the daily token cap makes it impractical for sustained development work.
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.
