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.

Sudowrite

Sudowrite is an AI writing assistant designed for novelists, short story writers, and screenwriters who need help developing plot, prose, and characters. It offers specialized tools like Story Engine for structured novel drafting, Describe for sensory scene details, and Brainstorm for unstuck moments. Unlike general-purpose AI writers, it is tuned for creative fiction rather than marketing copy. The tradeoff is that it is narrowly focused, so non-fiction and content creators will find limited utility here.
