Build · real repo + live preview
Build apps by chat
Describe an app and bychat scaffolds a real, full-stack web app — with a live preview you iterate on and publish.
bychat turns a plain-language description into a working application. An AI agent scaffolds and edits a real GitHub repository you fully own, CI builds it, and a live preview serves the running app so you can see every change as it happens. You keep iterating in the same chat thread until it's right, then publish a live build.
It's made for founders, product owners, agencies, and anyone who wants to turn an idea into a real product without waiting on a development team. Every message becomes a commit, so the whole build history stays in one timeline you can revisit — and because the code is a normal repo, there's no lock-in.
How it works
Describe it
Tell the chat what app you want, in plain language — features, pages, the works.
Watch it build
The agent writes the code and a live preview shows the running app. Iterate by chatting.
Publish
Ship a live build when it's ready, and keep editing whenever you like.
Example prompts
Copy one to start, or write your own — bychat takes it from there.
Build a todo app with projects, due dates, and a calendar view. Clean light-and-dark theme, drag-to-reorder, and a quick-add bar.
Make an internal CRM: contacts list with search and filters, a contact detail page with notes and a timeline, and a simple pipeline board.
Create a booking app for a barber shop: pick a service, choose a time slot, and confirm — with an admin view of the day's appointments.
Build an expense tracker with categories, a monthly summary with charts, and a CSV import.
Frequently asked questions
Do I need to know how to code?
No. You describe the app in plain language and the AI agent writes and edits the code for you. Anyone can go from an idea to a working app from a single prompt.
Do I own the code?
Yes. Every app is a real GitHub repository you fully own from the first message. Review every commit, connect your own GitHub, and export the code anytime — no lock-in.
Can I import an existing project?
Yes. You can import a project from GitHub or Lovable and keep building on it by chatting — the agent picks up your code, runs a live preview, and continues from there.
How does bychat actually build it?
An AI agent scaffolds and edits the repo and commits each change, CI builds the app, and a live preview serves it for you to test. Each message becomes a commit, so the build history stays in one timeline you publish from.
