Write the spec.
Let agents build it.
Prefill is a desktop app that turns your documents into working software. Write a product spec, and AI agents implement it — section by section, with live progress right in your document.
Document-driven
Your spec is the source of truth. Each section becomes a task agents execute against your codebase.
Live progress
See what each agent is working on in real time — status overlays per section, no switching tools.
Smart orchestration
Tasks run in the right order with automatic dependency resolution. Independent sections build in parallel.
