Replit Agent recreated a full-stack product, added seven RAG features, and produced a demo video in about 12 hours.

Done with Replit Agent· Advanced· May 2026

What they did
They gave Replit Agent an existing full-stack platform and asked it to reconstruct the system from scratch. After that, they had it layer seven new capabilities onto a live RAG app and create a cinematic demo video. The work ran for roughly 12 hours and ended with 46 commits and more than 14,000 lines of code.
How it went
Three products went out the door in the same day. The sprint took place on a free Replit Agent day.
Tips
Keep the request split into clear blocks so the agent can tackle them one by one. Ask it to stop for approval before any database edits, publishing step, or other change that cannot be rolled back.

Try it yourself with Replit Agent

I’m working on [project link or name]. First, recreate the current app so it matches the behavior and structure I already have. Then add these items to the live product: [feature 1], [feature 2], [feature 3], [feature 4], [feature 5], [feature 6], [feature 7]. Check each change as you go, and give me a brief report of what you updated. If you reach a step that would modify the database, publish to production, remove data, or send anything outward, stop and ask for my approval before proceeding.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
